Document: Bratsk Reservoir Perch Fishery 2nd surveillance report page 4 Date of issue: November 2018 1 Background This report contains the findings of the 2nd surveillance cycle in relation to the Bratsk Reservoir trapnet perch fishery. The client’s responses to the conditions of certification were set out in the Client Action Plan (CAP). Progress associated with the actions set forth in the CAP was examined as a part of this surveillance audit. For each condition, the report sets out progress to date. This progress has been evaluated by Marine Certification Audit Team (set out below as “Progress on Condition”) against the commitments made in the CAP.

Table 1. Revised principle scores Principle Final Principle Scores Principle 1 – Target Species 83.3 Principle 2 – Ecosystem 80.3 Principle 3 – Management System 80.2

1.1 Update on the fishery since the 2015 surveillance audit Changes to Management systems: There were no major changes highlighted for the fishery or management system. In the 2016, the fishing parcels were formally distributed between the users based on contracts. As a result, the number of used fishing parcels in the reservoir increased up to 174 (i.e. 2.3 – fold). This resulted in increase of the catch. Changes to Relevant regulations: None identified. Changes to personnel involved in science, management or industry: There have been no notable changes to the organisations managing the fishery. In 2018, ownership of Bernard Wolf over Bratskaya Ryba was officialy approved by the Federal Antimonopole Service (http://www.interfax-russia.ru/Siberia/special.asp?sec=1737&id=930587). This change in personalities does not result at all in changes of the management of the company. Changes to scientific base of information – including stock assessments: No significant changes in the scientific base of information regarding this fishery were identified. Stock assessments are conducted annually. Updates on enhanced fishery’s position in relation to scope criteria: Not applicable Any developments or changes within the fishery which impact traceability or the ability to segregate between fish from the Unit of Certification (UoC) and fish from outside the UoC (non- certified fish): None identified. None of the clients in the Bratsk Reservoir region is using MSC logo in product labeling or marketing. The only claim by the Client is that the fishery is MSC certified and is a sustainable fishery. No unsupportable claims are made.

3.1 Condition 1 Performance 1.2.1. Harvest strategy - There is a robust and precautionary harvest strategy Indicator in place Score 75 The Bratsk district perch fishery uses trap nets to catch 96 % of the harvest. The design of trap nets has been changed many times in order to obtain the greatest catch of the target species and avoid by-catch of juvenile fish. There is insignificant unwanted catch of other fish species in trap nets because fishers take all the harvest without any discard. Legal nets can have mesh size no smaller than 22 mm, but most Bratsk fishers use nylon nets with mesh sizes of 26 – 30 mm. These net sizes reduce catch of most small, juvenile perch. Rationale Nevertheless, some juvenile perch could be landed in net hauls with many fish. Fishers may try to sort out small fish and release them back to the water or use other alternative measures (or best practices) to reduce unwanted juvenile mortality. But there is no record of alternative measures and their regular review. Therefore, scoring issue 1.2.1 (f) Review of alternative measures, receives a score of 60 and PI 1.2.1 scores 75 overall and a condition is required to review of alternative measures. Within four years, the Client should demonstrate a regular review of the potential effectiveness and practicality of alternative measures to minimize trap Condition net mortality to unwanted catch of juvenile perch and implement such measures as appropriate. Surveillance 1: The Client should develop a monitoring program to determine the amount of perch juvenile by-catch and the effectiveness of several alternative methods to reduce mortality. Prepare Year 1 report summarizing monitoring protocols and promising methods. No change expected in the score. Surveillance 2: The Client should continue the Year 1 monitoring program. Also, the Client should discuss possible changes to harvest practices to minimize juvenile by-catch with fishery managers and fishermen. Prepare a Year 2 report with evidence of discussions in the form of meeting minutes, draft rules, recommendations, or other records to demonstrate a review of Milestones harvest practices and alternative methods. No change expected in the score. Surveillance 3: The Client should present monitoring data and recommend alternative measures to reduce mortality. Prepare Year 3 report describing amounts of juvenile by-catch in trap nets and recommenced measures to reduce it. No change expected in score. Surveillance 4: The Client should implement appropriate measures to minimise perch juvenile by-catch and demonstrate a regular review process to evaluate their effectiveness. Prepare a Year 4 report describing findings and processes. Condition expected to be fully met and with an expected score of 80.

Document: Bratsk Reservoir Perch Fishery 2nd surveillance report page 10 Date of issue: November 2018 Year 1: Design a monitoring program to determine the amount of perch juvenile by- catch. Gosrybtsentr will lead the monitoring program and design the sampling protocols. They will work with fishermen to collect data from survey nets and commercial catch. Sign a contract with Gosrybtsentr to manage Condition 1 monitoring in collaboration with Bratsk Fish fishermen. Bratsk Fish will organise a “Fishermen Council” to support the monitoring program and review juvenile by-catch data, among other duties. The Council will include mostly local fishermen, but also management agencies, academic scientists, and other stakeholders with an interest in Bratsk Reservoir fisheries. The Fishermen Council will evaluate alternative measures to minimize juvenile by-catch, such as increasing mesh size, shaking the net, pulling the net slowly, etc. Fishermen will discuss possible improvements at Fishermen Council meetings. Year 2: Client action plan Begin monitoring according to Year 1 protocols. Determine amount of perch juvenile by-catch in sampling program. Review results with Gosrybtsentr and Fishermen Council and consider measures to reduce by-catch, if necessary. Year 3: Continue monitoring methods developed in Year 1. Review results with Gosrybtsentr, Fishermen Council, regional fishery councils and other stakeholder to consider alternative measures to reduce by-catch. Analysis of Year 2 monitoring data. Make recommendations for effective and practical methods to reduce juvenile by-catch. Year 4: Analysis of Year 3 monitoring data. Summarize results. Hold at least two meetings between Bratsk Fish fishermen and Gosrybtsentr to determine the importance of juvenile by-catch and review alternative measures. Establish a regular review process, if necessary to consider alternative measures to reduce unwanted catch. The Client arranged with Gosrybtsentr to conduct research and monitoring to Consultation on support the Client Action Plan. Marine Certification consulted with condition Gosrybtsentr to verify their commitment and to ensure that the Client Action Plan (CAP) is reasonable and attainable within the specified timeframe. The Client has contracted Gosrybtsentr to develop a joint and a monitoring program. In the framework of this program, Gosrybtsentr conducted the research to determine the ages of maturity of perch and their age in the commercial catch. With these data, scientists determine the juvenile perch Progress on catch rate. In particularly, the average annual catch of immature juvenile Condition [Year perch in the Bratsk Reservoir in 2012 - 2016 amounted about 173.5 tons or 1st] 22.6% of the total catch. Client established a Fishermen’s Council that met three times in its first year. In April 2017, a group of fishermen met at Bratsksya Ryba to discuss the problem of reducing juvenile mortality. Despite minimal meshsize allowed by

Document: Bratsk Reservoir Perch Fishery 2nd surveillance report page 11 Date of issue: November 2018 the local fishing rules is 20 mm, the fisherman decided to use meshsize 24-26 mm in trapnets, which reduces the by-catch of juvenile perch. This is based on long-term empirical experience of fisherman, and there are no commercial reasons to change this meshsize. After reviewing the advantages and disadvantages of several possible alternative fishing methods of reducing juvenile mortality (changing mesh size; changing fishing locations; changing times or seasons; and net handling practices), fishermen identified that the most practical approach is changing of location of trapnets.

Conclusion: These actions effectively addresses the first annual surveillance milestone according to which the Client should develop a monitoring program and prepare Year 1 report to address this condition. Partly, the results of this year also address the second audit milestone because the Client provided numeric information about the fishing mortality of immature perch.

(meeting summary) In the framework of monitoring program, Gosrybtsentr conducted the research to determine the perch maturity age. This allowed to determine the percentage of juvenile perch in commercial catches. It was established, that in 2012-2017 in the Bratsk reservoir, all perch mature at the age 3 years, when their mean body length is 15.6 cm. 40% of fish of both sexes reach sexual maturity at 2+, and all perch less than 15 cm are juveniles. Using these figures, it was shown, that the average annual catch of immature perch in the Bratsk Reservoir in 2012 - 2016 amounted about 52.8 tons or 10.2% of the total catch. These values were refined in comparison with those reported last year. Allocation of new fishing grounds and/or change the boundaries of old ones in Progress on 2017 made it possible to test the change of installation of trap nets as an Condition [Year alternative measure of reducing the by-catch of immature perch. Indeed, it 2nd] was shown that this measure reduced the percentage of by-catch of juvenile perch in the Bratsk district by 4.9 times compared with period 2012 – 2016 (from 10.2 to 2.1%). The absolute catch of juveniles reduced in 2017 three- fold up to 17.5 mt [1]. Before the start of the 2018 fishing season, the data on age and size of maturation of perch in the Bratsk reservoir was presented to the fishermen at the meeting of the Fishery Council. In accordance with the decision of the Council, perch under 15 cm long and weighing less than 60 g is considered immature fish and is bought by the Bratskaya Ryba from fishers for reduced price [2]. This attempts to use economic incentives in order to reduce catching of immature perch.

3.2 Condition 2 Performance 1.2.2. Harvest control rules and tools -There are well defined and effective Indicator harvest control rules (HCRs) in place Score 75

HCRs are well defined and in place to ensure the target stock (perch) stays above the point of recruitment impairment (PRI) and fluctuates around levels of Maximum Sustainable Yield (MSY). Specific HCRs include annual levels of Recommended Allowable Catch (RAC) and stop fishing rules when harvest reaches 70 % of this amount. Other HCRs involve quotas assigned to individual fishermen for specific gear types in defined areas. Also, fishing rules define allowable gear, seasons, areas, and species to harvest. However, these HCRs Rationale may be subject to uncertainties related to the total amounts of fish removals from recreational and IUU fishing. Managers estimate the level of recreational fishing based on questionnaires received from recreational fishers. Managers estimate the level of IUU catch by applying a correction factor to the official catch statistics. Fishery scientists at Gosrybtsentr determine values for recreational and IUU removals but the transparency of their analysis is not obvious. Therefore, scoring issue 1.2.2 (b) HCRs robustness to uncertainty, receives a score of 60 and PI 1.2.2 scores 75 overall. Condition Within four years HCRs are likely to be robust to the main uncertainties.

Surveillance 1: The Client should design a monitoring program to identify uncertainties related to fish mortalities in the reservoir. It should consider the amounts of recreational and IUU fishing, juvenile by-catch and significant Milestones sources of non-fishing mortality. The monitoring strategy should include activities to evaluate perch juvenile by-catch as described in Condition 1. Prepare Year 1 Report with monitoring strategy. Surveillance 2: The Client should implement a monitoring program to determine the sources and amounts of fish mortality based on Year 1

Surveillance 3: The Client continues the monitoring program in Year 3. The Client should meet fishery managers to review data and discuss possible changes to HCRs, if necessary. Prepare Year 3 Report with evidence of manager meetings in the form of meeting minutes, presentations, draft rules, or other records to demonstrate management consideration of uncertainties in HCRs. No change expected in the score. Surveillance 4: The Client should provide evidence that HCRs are robust to sources of uncertainty, including those from recreational and IUU fishing, juvenile removals, and any significant sources of natural mortality. Managers should adjust HCRs, if appropriate. Condition expected to be fully met with an expected score of 80. Year 1 : Sign a contract with Gosrybtsentr to manage monitoring for Condition 2. Design a monitoring program to account for all sources of fish mortality to support Harvest Control Rules (HCRs). Collect data for: a) Recreational fishing: Conduct a sampling program to estimate the level of recreational fishing based on questionnaires received from recreational fishers or “amateur fisher card.” Estimate the number of fishers during winter and summer periods, the intensity of fishing, and fisher behavior to target certain species. b) Juvenile by-catch: see Condition 1 c) IUU fishing: Gather all official data available on IUU fishing (from Gosrybtsentr, FAR, and Baikalrybvod); and describe how managers make estimates of IUU fishing. Client action plan d) estimates of non-fishery mortality. Year 2: Collect data according to the monitoring protocols developed in Year 1. Present data in a Year 2 Report. Year 3: Continue monitoring program according to Year 1 protocols. Present data in Year 3 Report. Review use of data in HCRs and discuss possible changes to HCRs. Review results with Gosrybtsentr, Fishermen Council, regional fishery councils and other stakeholders to consider measures to reduce unwanted or unreported catch. Year 4 : Analyze Year 3 monitoring data. Prepare Year 4 Report. Meet with fishery managers to review and share data and to implement modification in HCRs, if necessary. The Client arranged with Gosrybtsentr to conduct research and monitoring to Consultation on support the Client Action Plan. Marine Certification consulted with condition Gosrybtsentr to verify their commitment and to ensure that the Client Action Plan (CAP) is reasonable and attainable within the specified timeframe.

Document: Bratsk Reservoir Perch Fishery 2nd surveillance report page 14 Date of issue: November 2018 The Client has contracted Gosrybtsentr to develop the relevant monitoring program. In the framework of this program, Gosrybtsentr conducts research to determine the ages of maturity in perch stocks and the ages of fish in the commercial catch. With these age data, scientists determine the juvenile catch rate for perch. In particularly, the average catch of immature juvenile perch in the Bratsk Reservoir in 2012 - 2016 amounted to 173.5 tons or 22.6% of the total catch. Juvenile removal is taken in consideration by the management system because are already used in the forecasts. Besides, in the report, the scientists present methods and protocols for calculating values of IUU and recreational catches of perch, which also taken into consideration while assessing the total fishing mortality in the reservoir. The illegal catch in Bratsk reservoir is mainly for larger fish with significant commercial value, such as omul, peled, bream, Prussian carp, pike, Amur catfish. The estimate of the illegal catch of perch is based on the number of confiscated prohibited fishing gear such as gill nets during a spawning season when the most of illegal removal of perch takes place. According to Angara- Baikalsky Territorial Administration (ABTU, Bratsk Division), in 2015 fish inspectors confiscated 232 gill nets with a total length of 11,855 m. 50% of these nets had a mesh size of 32-40 mm, suitable for catching perch. Assuming, based on long-term observations, an average catch of perch during the spawning season of 15 kg per net, the estimated catch from confiscated nets could be 1740 kg/day. Accepting that illegal fishing nets are in operation every third day during the spawning season of 30 days, the possible IUU catch Progress on by these nets could reach 17.4 mt. Assuming that fish inspectors collect Condition [Year approximately 10% of illegal nets, the total illegal catch of perch in the Bratsk 1st] reservoir is estimated 174 mt per year. According to Aleksander Ivanov, the number of violations of fishing rules is increased last 8 years for about 15%. He links this with worsening of the economical situation in the country. Also, procedure of registration of violations became more complicated and long which resulted in decrease of number of violations because poachers have time to inform colleagues about the check. Therefore, an actual level of poaching may increase even more than 15%. Recreational catch changes from year to year quite a lot, mostly due to changes of weather conditions. It is the most intensive in November- December and in April-May. Recreational fisher are more active when there is less snow on the ice because absence of snow makes accessible many locations in the reservoir with car. According to the estimates, the recreational catch may vary from year to year about three-fold. Maximum estimates approached 500 mt. Last years the distribution of recreational fishers narrowed and they concentrated mostly around the city of Bratsk, probably because of economical reasons (high prices for fuel). Earlier more people went fishing also from other villages along the reservoir coast. Many fishers from both Bratsk and villages sale their catch to representatives of fish processing factories from other regions who come to buy fish to the reservoir. Others use catches in the household or sales the catch locally. In the 2016, the magnitude of recreational catch is estimated based on field observations and surveys of fishers. According to the surveys, the average catch ranges from 0.3 to 6 kg per day near the Bratsk city and up to 35 kg per

Document: Bratsk Reservoir Perch Fishery 2nd surveillance report page 15 Date of issue: November 2018 day in remote parts of the reservoir. Factored in number of fishers in different parts of the reservoir, the amateur fishers catch about 2.7 kg of perch per day during the ice period. In free-of-ice season, the fishermen catch small amounts of perch with rod and reel estimated as 20 mt. The most intensive recreational fishing occurs near the settlements, where density of fishers is 20 - 100 persons per square km, and in remote the density is 2-4 fishermen per sq km. According to the surveys, about 180 people are fishing each day during ice period. Based on theses, Gosrybtsentr scientists estimate the average total amateur catch on the Bratsk Reservoir in the first quarter of 2016 as 131 tons. Seasonal fluctuations of water level of the reservoir, are recognized as a potential source of non-fishing mortality, according to researchers of Gosrybtsentr. The researchers note in low-water periods the concentration of immature perch in the coastal zone may increase, which may cause an increase of their fishing mortality, but this factor is not considered to be important for perch. In addition to effects of water level fluctuations, discussed in the PCR report, the researchers mentioned also alteration of sediments contaminated with disc discharge from the enterprises of petrochemical and power generation located in Angarsk town (upstream part of the reservoir).

Conclusion: The provided information effectively addresses the first annual surveillance milestone that the Client should develop a monitoring program and prepare Year 1 report to address this condition. The Client reported the first results of that program which also meets the criteria of the milestone of the second audit, i.e the Condition 2 is performed ahead of the schedule.

Status of Condition is open and on target Condition Gosrybtsentr conducted the research to determine the ages of maturity of perch and their age in the commercial catch. With these data, the researhers determined the juvenile perch catch rate (see Condition 1). In 2017, the catch of immature perch reduced three times (from 52.8 tons in 2012-2016 to 17.5 tons in 2017) (see Condition 1). In addition to Gosrybtsentr the monitoring of Progress on the species composition and catches of commercial trap nets is carried out by Condition [Year the state fishery inspectorate. Alltogether, Gosrybtsentr and the State Fish 2nd] Incpection check about 60 trap nets and about 190 fishermen a year. In the 2017, the magnitude of recreational catch is estimated based on field observations and surveys of fishers. According to the surveys, the average catch of the recreational fisher ranges from 2.2 to 5 kg of perch per day in winter period. The total number of fishermen in the Bratsk district varied from

Document: Bratsk Reservoir Perch Fishery 2nd surveillance report page 16 Date of issue: November 2018 30-60 people on workdays and from 200 to 300 people on weekends during the period from January to March (including December of the next winter season). Based on this, Gosrybtsentr estimates the recreational catch in the Bratsk fishery region for the ice cover season of 2017 as 42,7 tons [3]. According to Alexander Ivanov (ABTU), in free-of-ice season, the fishermen catch small amounts of perch with rod and line since the main target species are bream and pike. Thus amount of perch caught in ice-free season is considered negligible. To estimate the IUU catches of perch, scientists continued to collect statistical data on the number of confiscated prohibited fishing gear such as gill nets during a spawning season when the most of illegal removal of perch takes place [4,5]. Assuming that only every tenth illegal net is confiscated, the scientists determine (i) the total length of confiscated nets with a mesh size suitable for perch fishing, (ii) the average perch catch per net in the spring period, and (iii) taking into account the total number of days the nets are have been operating, they calculate the total size of IUU catch. Estimated values of amateur and IUU catch of perch are used as “expert estimates” in justifying the total catch of perch in the Bratsk reservoir. According to the official statistics, in 2017, the commercial catch of perch was 1,113 tons, and amaterur and IUU catch is 300 mt, thus the total catch is 1,413 tons [10]. At the same time, the provided level of detalistaion of the methodology and data is less than at the Year 1 survelliance. Due to the general decline of poaching at the Bratsk Reservoir, the work of State Fish Inspection is becoming more focused on habitat monitoring in connection with the activities of industrial enterprises, construction in the water protection zone, etc. According to researchers of Gosrybtsentr and to Alexander Ivanov (ABTU), since the last surveillance audit the new sources of non-fishing mortality of perch have not been identified.

Conclusion: The provided information effectively addresses the second annual surveillance milestone according to which the Client should collect data according to the monitoring protocols developed in Year 1.

However, as described in Condition 2, there are data gaps related to fish mortalities associated with recreational and IUU fishing and juvenile by-catch. Moreover, the assessment team found no catch data for trap nets only, the Rationale UoA. Rather, available fishery data present aggregated catches for all gear types; trap nets, gill nets, and beach seines. Without catch data for trap nets, it is not possible to know the true impact of the UoA on perch stocks. For this reason, scoring issue (c) “Comprehensiveness of information” scores a 60 and PI 1.2.3 scores a 75 and the assessment team set Condition 3.

Milestones: Surveillance 1: The Client should design a monitoring program to determine the amount of perch caught from trap nets only. It should be part of an integrated monitoring program that also collects data about IUU and recreational fishing, and juvenile by-catch. Prepare Year 1 report describing monitoring program. Surveillance 2: The Client should implement the monitoring program defined in Year 1. Prepare a Year 2 report to present monitoring data. No change expected in the score. Milestones Surveillance 3: The Client should continue monitoring activities started in Year 2. Also, the Client should review results with fishermen and fishery managers and discuss possible data gaps and/or changes to HCRs. Prepare Year 3 Report with evidence of discussions in the form of meeting minutes, draft rules, presentations, or other records to demonstrate consideration of monitoring results. No change expected in the score. Surveillance 4: The Client should prepare Year 4 Report providing comprehensive information about all fishery removals from the stock, including those from trap nets only, recreational and IUU fishing (Condition 2) and juvenile by-catch (Condition 1). Condition 3 expected to be fully met with a score of 80. Year 1: Design a monitoring program to determine catch composition in trap nets. The program will include a fishery-independent field survey combined with information collected from commercial fishermen. Client action plan Gostrybcentr will establish a network of survey trap nets and design monitoring protocols that specify sampling locations, methods, times, and frequencies. Sign a contract with Gosrybtsentr to manage monitoring for Condition 3. Select Bratsk Fish fishermen to work with Gosrybtsentr to gather information

Document: Bratsk Reservoir Perch Fishery 2nd surveillance report page 18 Date of issue: November 2018 about catch composition of trap nets. Fishermen will record catch composition by gear type in logbooks. Year 2: Determine the catch composition of different species in survey trap nets. Collect data according to the monitoring protocols developed in Year 1. Analyze survey and logbook catch data for trap nets only and compare them to catches in other gear types. Year 3: Continue monitoring using Year 1 protocols. Meet with fishery managers to review data relevant to HCRs s and consider possible modifications. Year 4: Analyze Year 2 - 3 monitoring data and describe trap net catch for at least on year for all three districts in Bratsk Reservoir. Meet fishery managers to review data about all fishery removals and how they support the harvest strategy. Prepare Year 4 Report with data and recommendations. The Client arranged with Gosrybtsentr to conduct research and monitoring to Consultation on support the Client Action Plan. Marine Certification consulted with condition Gosrybtsentr to verify their commitment and to ensure that the Client Action Plan (CAP) is reasonable and attainable within the specified timeframe.

The Client has contracted Gosrybtsentr to develop a monitoring program to assess fish mortalities associated with recreational and IUU fishing and juvenile by-catch of perch (see details on progress of Conditions 1 and 2), and to determine the amount of perch caught from trap nets only. The Client identified fishing logbooks as an information source allowing to separate catch obtained with different gear (traps, beach seines and gillnets). The logbooks already contain an entry for gear types, fishermen provide gear type information in logbooks and fishery inspectors of the ABTU check the presence of such records which must be kept at least five years. At the same time, it must be emphasized that these data are not reported to ABTU, and, in fact, Progress on never used by the management system. Bratskaya Ryba will collect available Condition [Year logbook data and analyze catch information to separate catches by different 1st] gear types. Such data will be analyzed for three administrative districts – Bratsk, Balagansk and Usolsk.

Conclusion: These actions effectively addresses the first annual surveillance milestone that the Client should develop a monitoring program and prepare Year 1 report to address this condition. Partly, in terms of information on recreational and illegal catch, these data meet milestone of the second year audit.

The results of inspection of commercial fishermen in Bratsk and Balagansk administrative districts are provided as acts, containing information on the number of fishing gears actually used by the fishery brigades, on the species composition and catch volumes [7]. Also, Gosrybtsentr works with selected fishermen of Bratskaya Ryba conducting a complete biological analysis (species composition and mass measurements of mass species) from commercial trap nets [6]. The answers from the departments of fish protection in the Bratsk and Balagansky administrative districts has been received by the request of Bratskaya Ryba for the number of inspections of fishing brigades [5,7]. This work is fulfilled to determine the amount of perch caught from trap nets only.

Conclusion: These actions partly address the second annual surveillance milestone that the Client should present the monitoring data of trapnets. The information on the survey of the trapnets are presented, but the data itself are not summarized and not compared with overall structure of catches in different administrative districts.

3.4 Condition 4 Performance 1.2.4. Assessment of stock status - There is an adequate assessment of the Indicator stock status Score 75 The stock assessment takes a precautionary approach. In setting RACs (quotas) it does not consider stocks for the entire reservoir. Rather it only considers stocks on the fishing grounds, representing 24% of the total area. Since the fishery operates on only about a quarter of the available habitat, we assume Rationale that they also fish on 24 % of the total population because fish densities are the same in 24% (fished) and 76 % (non-fished) parts of the reservoir. Despite this precautionary approach, the assessment team recognizes uncertainties related to sources of all fish mortality. These include data gaps identified in other conditions: juvenile by-catch (Condition 1); recreational and IUU fishing

Document: Bratsk Reservoir Perch Fishery 2nd surveillance report page 20 Date of issue: November 2018 (Condition 2); and perch catch from trap nets only (Condition 3). Other sources of uncertainty may involve significant non-fishery related mortalities, such as those associated with changing water levels in the reservoir. Together these data gaps represent uncertainty in the assessment and scoring issue (c) receives a score of 60.

The Client arranged with Gosrybtsentr to conduct research and monitoring to Consultation on support the Client Action Plan. Marine Certification consulted with condition Gosrybtsentr to verify their commitment and to ensure that the Client Action Plan (CAP) is reasonable and attainable within the specified timeframe. The Client has contracted Gosrybtsentr to develop a monitoring program to determine fish mortalities associated with recreational and IUU fishing and juvenile by-catch of perch. Gosrbytsentr scientists estimate amateur fishing based on surveys and field observation. They estimated IUU fishing based on the amount of confiscated nets and the assumed catch-per-unit-effort of all illegal gear (see more details in parts related to conditions 1 and 2). The total estimated unofficial catch is 325 mt. for Year 2016 Scientists add these removals to the official catch in a category called “expert assessment of catch.” For example, in 2016: Registered commercial catch = 912.4 tons Amateur catch + IUU catch = 325 tons Expert assessment of catch = 1237.4 tons. Scientists assess the juvenile by-catch for perch by determining the ages of maturity in perch stocks and the ages of fish in the commercial catch. For example, the average catch of immature juvenile perch in the Bratsk Reservoir in 2012 - 2016 amounted to 173.5 tons or 22.6% of the total catch. Juvenile removal is already taken into consideration by the management system Progress on because are already used in the forecasts. Condition [Year There is a plan in place to address the issue of the amount of perch caught by 1st] trap nets only by retrospective analyzis of stored logbooks. The other potential sources of non-fishery mortality in Bratsk reservoir are seasonal fluctuations of water level of the reservoir, chemical pollution, timber rafting. These sources were also considered, but were decided not to be important factors for perch mortality.

Conclusion: The above actions effectively addresses the first annual surveillance milestone that the Client should prepare Year 1 report with analysis of key information gaps related with sources of fishery and non-fishery mortality. They also partly address Year 2 milestone because provide information that the management system takes into account some findings while performing stock assessments.

Measures to minimize juvenile by-catch include legal minimum net mesh size (20 mm) and allowed fishing areas. However, there is no evidence that fishery managers have considered the threat of juvenile by-catch or regularly review alternative measures to minimize it. For this reason, the Rationale assessment team scores Scoring Issue (e) “Review of alternative measures” as 60. Since juvenile by-catch issues occur in both primary main stocks (roach, bream and Prussian carp and target stock (perch); Condition 5 (primary) overlaps with Condition 1 (target).

Document: Bratsk Reservoir Perch Fishery 2nd surveillance report page 24 Date of issue: November 2018 Condition [Year The Fishermen Council discussed the following possible methods to reduce the 1st] juvenile by-catch: 1) increasing mesh size; 2) change of fishing locations; 3) change fishing seasons; and 4) removal of juveniles by hand nets. Among these alternatives fishermen suggested the best two options as: 1) removing bream juvenile by hands from the trap; and 2) changing of areas with high concentrations of juveniles. As for now, the juvenile cyprinids are released after the catch already taken onboard of the boat. This definitely causes a high mortality of juveniles. It is considered that removing the fish from the trap, when they are still in water, would reduce mortality significantly. This is however more labor-intensive, thus it is needed to organize the process in the most effective way. If the by-catch of juvenile cyprinids exceeds 25-30%, the fishers usually change the location of the trap to reduce the by-catch.

It was shown, that the average annual catch of immature juveniles of the main primary species in the Bratsk Reservoir in 2017 compare to 2016 decreased for roach from 13% to 10%, for bream from 62% to 23%, for Prussian carp from 36% to 11% [9]. The Fishermen Council recognized that the procedure for changing fishing places is the most effective in order to avoid high by-catch of juveniles.

However there are few data to estimate unwanted catch of juvenile species as described in Condition 5 and few data related to IUU and recreational fishing for roach, bream, and Prussian carp. Also, there are no data to describe catch of these species in trap nets only since catch data aggregate catches for combined gear types. As a result, the assessment team was not able to determine primary main species catch composition specifically for the UoA (trap nets). Therefore, the team believes that information is inadequate to support a management strategy and scoring issue (c) receives a score 60. Condition 6 (for primary species) overlaps with Condition 3 (for target species) since they both collect catch composition from trap nets.

Marine Certification consulted with Consultation on Gosrybtsentr to verify their commitment and to ensure that the Client Action condition Plan (CAP) is reasonable and attainable within the specified timeframe.

The Client designed a monitoring program to determine catch of primary species in trap nets. The program will review available logbook data to determine catch by gear type. Fishing logbooks already contain an entry to document gear type; but the official database does not record it. Therefore Bratskskaya Ryba will create a non-official database to monitor the trap net catch among its fishermen. Also, Gosrybtsentr provide information about amounts of juvenile catch of roach, bream and Prussian carp in 2016.

The team felt that there was no management strategy for ETP species due to: No records of ETP catch or interactions; Rationale No information about monitoring of ETP populations; No information about determination of red list status (Matveev, et al 2009); and No evaluation of a partial strategy based on information about ETP species. While it highly unlikely that the perch trap net fishery causes adverse effects to ETP species, there is little information and no cohesive management strategy to manage ETP species. For these reasons, the team assigned PI 2.3.2 an overall score as 65.

Within four years the Client should: a) develop and put in place a strategy to ensure that the perch trap net fishery does not hinder the recovery of ETP species; b) provide objective evidence that the strategy works; and c) Condition implement a regular review process of alternative measures reduce mortality of ETP species and implement them, as appropriate.

Surveillance 1: The Client should review existing measures to manage ETP species and recommend possible improvements, including procedures to collect information about any ETP catch or interactions with the fishery in all three districts. Prepare Year 1 Report with findings and recommendations. No change in score expected. Surveillance 2: The fishery should review data about ETP species interactions and start a process to discuss possible measures to minimize mortality. The Milestones Client should identify measures to support a management strategy. Prepare Year 2 with evidence of discussions and a summary of recommended management measures. No change of score expected.

Surveillance 3: The fishery should implement some management measures defined in Year 2 and conduct meetings with stakeholders to review their effectiveness. Also, the fishery should continue to gather information about the status of ETP populations in the reservoir. Prepare Year 3 Report with

Document: Bratsk Reservoir Perch Fishery 2nd surveillance report page 30 Date of issue: November 2018 findings. No change in score expected.

Surveillance 4: The Client should provide objective evidence that management measures implemented in Year 3 and 4 are both adequate and relevant to the fishery, including measures to collect adequate information and to regularly review alternative measures to minimize ETP species mortality in trap nets. Expected score: 80. Year 1: Review possible elements of a management strategy and discuss them with fishermen, Fishermen Council, and Gosrybtsentr. Elements may include: • Monitoring systems • Scientific research • Monitoring, Control and Surveillance. (MCS) • Participation in national research plans • Consideration of stakeholder input. Contact fishery (or nature protection) managers in Bratsk, Balagansk and Usolsk districts to request information about ETP species. Gather available data as described in Condition 8 for Usolsk and Balangansk districts. Within four years, the Client should demonstrate a regular review of alternative measures, as necessary, to minimize UoA mortality on unwanted catch of ETP species.

Year 2: Client action plan Evaluate quantities of ETP catch in trap nets based on monitoring protocols for catch composition defined in Condition 3 for Bratsk district. Conduct stakeholder interviews in Bratsk, Balagansk and Usolsk to gather information about ETP interactions. Identify measures, or elements, to support a management strategy and discuss them with the Fishermen Council, Gosrybtsentr, and other stakeholders.

Year 3: Continue Bratsk district monitoring based on ETP protocols defined in Year 1. Expand ETP monitoring to Balagansk and Usolsk districts. Continue stakeholder interviews. Analyze Year 2 - 3 monitoring data and evaluate ETP status based on preliminary results. Review alternatives measures to minimize mortality of ETP species. Discuss them with the stakeholders such as the Fishermen Council, Gosrybtsentr, FAR, etc.

Document: Bratsk Reservoir Perch Fishery 2nd surveillance report page 31 Date of issue: November 2018

Year 4: Present a management strategy to gather adequate information, reduce ETP interactions, and conduct regular reviews of alternative measures to minimize ETP mortality. The Client arranged with Gosrybtsentr to conduct research and monitoring to Consultation on support the Client Action Plan. Marine Certification consulted with condition Gosrybtsentr to verify their commitment and to ensure that the Client Action Plan (CAP) is reasonable and attainable within the specified timeframe. An executive committee of the Bratskaya Ryba MSC team met on 26 April 2017 and discussed elements of an ETP strategy. These elements include: Fishing rules and enforcement. Baikal region fishing rules and ABTU enforcement. Communication. Catalogue of Rare Species published and distributed among fishers. Coordination among managers in Bratsk and Balagansk districts regarding information on interaction of ETP species with perch traps. Fishermen Council reviews and comments on ETP interactions. Research and policy. Dr. Ponkratov’s suggestion to prohibit commercial fishing in river mouths and subsequent changes in fishing rules. Fishery stakeholders in the Bratsk district reported no recent interactions of ETP species with trapnets. Angara River Red Book fish species mostly disappeared after the creation of the large reservoir and the loss of riverine habitat. The Client got information from the ABTU at Balagansk district about Progress on absence of interaction of ETP species with trapnets. In the Year 2, it is planned Condition [Year to compare known exact distribution of ETP species, especially in the Usolsk st 1 ] and Balagansk districts, with location of trap nets targeting for perch. Protected species occur under riverine conditions (rivers, central part of the reservoir), but trapnets are situated in coastal area where current is almost absent, because most of commercially important fish occur there. Absence of overlap of these distributions means absence of interaction of ETP species under the interest with perch fishing gear.

Conclusion: The provided information effectively addresses the first annual surveillance milestone. Year 1 report describes the elements of strategy towards reducing effect of trap nets on ETP species, and described available information of interactions of ETP species with the UoA fishing gear in the entire reservoir.

Since 2017, the monitoring of the species compositions and catch volumes of commercial trap nets in Bratsk fishery region is carried out in accordance with research protocols developed in the first year by the employees of the Gosrybtsentr in collaboration with fish state fishery inspectorate. Together, scientists and the state inspectors inspect about 60 trap nets and about 190 fishermen a year. According to research protocols, fishery logbooks and official letter from the state fishery inspection of the Bratsk region, no interactions of ETP species with trap nets have been found [4,6,7]. The results of inspection of commercial fishermen in Balagansk fishery region are provided as acts, containing information on the number of fishing gears actually used by the fishery brigades, on the species compositions and catch volumes [7]. As in the case of the Bratsk fishing area, there have been no cases of catching ETP species in the Balagansk fishery region in 2017 [5].

Progress on Conclusion: Condition [Year nd The provided information partly addressed the second annual surveillance 2 ] milestone. Year 2 report describes the analysis of the surveys of the ETP species catches, and evidences absence of them in surveyed catches in Bratsk and Balagansk administrative districts, but not in Usolsk administrative district.

3.8 Сondition 8 Performance 2.3.3 -- ETP species information Indicator Score 60 According to catch information, fishing logbook data, and interviews with fishery managers, there is little evidence of significant ETP interactions in the Bratsk district of the Bratsk Reservoir. However, many of the ETP species listed for the Irkutsk region, such as sturgeons and salmonids, occur in river ecosystems that vanished with the establishment of the Bratsk Reservoir. Today, relatively more of these river ecosystems remain in upstream portions of the reservoir in Usolsk and Balagansk districts. However, the assessment team did not find ETP information for the Balagansk and Usolsk districts or catch records for ETP species in any district. As a result, the assessment team Rationale concludes that there is some qualitative information to assess the UoA-related mortality of ETP species. But without some quantitative information, especially for Balagansk and Usolsk districts, the team assigns a score of 60 to scoring issues (a) “Information adequacy for assessment of impacts” and (b) “Information adequacy for management strategy” resulting in an overall score of 70 for PI 2.3.3. Data gaps and actions required for Condition 8 overlap with those of Condition 7 (PI 2.3.2 ETP Management Strategy) and both Conditions should be developed together.

Within four years, the Client should gather some quantitative information to assess the UoA-related impacts to ETP species for all three districts of the Condition Bratsk Reservoir and provide adequate information to support a strategy to manage impacts on ETP species.

Surveillance 1: The Client should gather information about ETP interactions with fishers, including logbook data and results of interviews with fishery managers in all three districts. Prepare Year 1 Report of findings. No change expected in the score.

Surveillance 2: The Client should review Year 1 ETP interaction data and consider innovative procedures to gather information about fishery interactions with ETP species. Prepare Year 2 Report to present findings and Milestones recommendations. Surveillance 3: The Client should continue to gather data about ETP species and expand information gathering to include all three districts in reservoir. Prepare Year 3 Report to summarize findings. Surveillance 4: The Client should present some quantitative information to determine impacts of the perch trap net fisheries on ETP species and to support ETP management measures. The Condition shall be fully met to score 80.

Since 2017 monitoring of the species compositions and catch volumes of commercial trap nets in Bratsk fishery region is carried out in accordance with research protocols developed in the first year by the Gosrybtsentr in collaboration with the State Fish Inspectorate. Totally, about 60 trap nets and 190 fishermen are inspected. According to research protocols, fishery logbooks and official letters from the state fishery inspection of the Bratsk and Balagansk administrative districts, catche of ETP species in commercial traps were recorded [4,5,6,7].

3.9 Сondition 9 Performance 3.2.2 -- Decision-making processes Indicator Score 75 Some information about the fishery’s performance and management actions is Rationale generally available on request to stakeholders. This was clear during meetings of the assessment team with agencies participating in fishery management.

Document: Bratsk Reservoir Perch Fishery 2nd surveillance report page 36 Date of issue: November 2018 Fishery managers and fishers provided good information to the assessment team. Results of fishing season and effectiveness of management actions undertaken are discussed at government agencies such as ABTU and FAR and also at Research Councils of fisheries institutes such as Gosrbytsenter and VNIRO on a regular basis. However, information on stock abundance, harvest by time and area, and fishery management decisions, is not reported regularly outside the management system. Occasional publications of related information provide a historical perspective, but they are not sufficient to allow stakeholders to track decision-making processes associated with relevant and timely findings and recommendations. The team was not able to collect all relevant information from non-fishery stakeholders, such details about the management system controlling water level changes in the reservoir. This information is important for understanding long- and short-term changes of fish abundance. The limited availability of fishery performance information outside the local management system and lack of explanations for actions associated with findings and recommendations results in a score of 60 for scoring issue (d).

Within three years, the fishery should implement procedures to provide public information relevant to fishery decision-making, in a transparent and timely Condition manner. Information should include results from research, monitoring, and evaluations along with explanations of how managers use information to make decisions. Surveillance 1: The Client should consider mechanisms to share public information about fishery performance and provide transparent explanations of how it is used to make fishery decisions.

3.10 Сondition 10 Performance 3.2.4 – Monitoring and management performance evaluation Indicator Score 60 The fishery has in place institutions and mechanisms to evaluate some parts of the management system. For example, public councils and government agencies have review processes to evaluate quotas, catches, and stock assessments, to minimize quota over-runs, and make in-season adjustments. But the assessment team did not identify mechanisms to evaluate key parts of the fishery management system, such as evaluations of UoA impacts on ETP species and catch composition by gear type. Moreover opportunities for external review are limited by the inconsistent Rationale availability of information outside the regional and local governmental management system. While managers discuss results of the fishing season and quotas at meetings of the ABTU and research councils of fisheries institutes, they do not typically provide comprehensive and timely information outside of the management agency for outside review. This includes information about stock size and harvest by time and area. While occasional publications of relevant information provide a historical perspective, they are not sufficient to enable a regular and timely review of the fishery-specific management system. Within three years there will be mechanisms in place to evaluate key parts of the fishery-specific management system and procedures to allow for Condition occasional external review of relevant issues, including the impacts of the perch trap net fishery on ETP species and catch composition by gear types.

Appendix I – Rescoring Evaluation Table No changes in this surveillance.

Appendix II – Fishery Information Fishery Area The fishery occurs in the Bratsk district of the Bratsk Reservoir of the Irkutsk Province Eastern Siberia.

Gear The fishery is prosecuted with trap nets in the coastal waters of the reservoir. Other gear types used in the reservoir such as beach seines and gillnets are not included in this assessment. Seasons Commercial perch fishing is allowed all year around, but in fact, the trap net fishing operations are carried out during ice-free period. The fishig season starts in the first half of May just after ice melting and continues till ice formation in late October – early November. Under-ice commercial fishing at the Bratsk Reservoir is carried out only using gillnets, which are not included in the assessment).

Organization Fishing parcels consisting of trapnet sites are leased to fishing companies by the government under a long-term lease arrangement. Only commercial fishing occurs in these parcels.

Figure 1. Bratsk Reservoir. The entire Bratsk Reservoir has a surface area of 5,470 square kilometers. It covers three fishing districts: Bratsk, Balagansk, and Usolsk. Bratsk Fish ltd. fishes in the Bratsk district at the north end of the reservoir. Managers defined 182.5 K hectares (ha) of potential perch habitat in the shallow coastal areas (less than 15 meters deep). Currently fishers use only 43 K ha of this habitat, leaving 139.5 K ha available for future fishing sites. The harvest strategy assumes the fishery can expand by increasing the area of fishing sites. Fishing mostly occurs in places with easy access and good roads. The red dots refer to monitoring sites described in Section 3.4 of PCR. Target Stock The European perch – Perca fluviatilis L. has wide distribution in Eurasian rivers, lakes, coastal areas of the seas. The species covers most of Europe except the Iberian Peninsula, northern England, Ireland, and at the Atlantic coast of Scandinavia, In Asia, it does not appear in the mountainous areas of the Caucasas, Central Asia, southern Mongolia, the Amur watershed, the Russian Far East, Kamchatka or Chukotka. Due to introduction of perch in the water bodies of Australia, New Zealand, South Africa and Azores islands, the habitat of the European perch has enlarged (Berg, 1949 Popova et al., 1993). In Russia, perch distribution extends from the northern border near the Arctic Ocean, from River Pasvic to Kolyma River, to the southern border of Black Sea and Northern Caucasia to the upper streams of Siberian rivers. Perch is a lake-river fish, living in the coastal vegetation zone of the water body, where it eats

Document: Bratsk Reservoir Perch Fishery 2nd surveillance report page 43 Date of issue: November 2018 zooplankton, benthic organisms and juveniles of different fish. The diet changes as the fish grows. The perch diet can vary depending on food availability from reservoir to reservoir. In some reservoirs perch eat zooplankton throughout its life or stays as a bottom feeder, not shifting to fish predation. In large lakes and reservoirs with diverse food webs, ecotypes can develop as two or three forms of the same species. These ecotypes can differ in habitat, feeding type and rate of growth. In earlier years, Bratsk Reservoir had two types of perch: 1) slow-growing coastal perch eating mostly invertebrates; and 2) fast growing deeper-water fish eating mostly juvenile carp and other perch. In subsequent years stock of fast growing ecotypes decreased and the size of fish declined (Mamontov, 1977). Scientists now believe that the ecotypes have merged and single population now lives in the reservoit (Pastukhov, 2015; Mamontov - stakeholder interviews). Perch are widely distributed in Bratsk Reservoir. The highest concentrations are confined to shallow areas less than 15 m depth. There is no perch affinity to a particular type of spawning area. Eggs are found in shallow waters among last year's vegetation in hollow areas on bottom, main in areas protected from the effects of wind and waves. Laying of perch eggs are found on submerged trees at depths of 5-7 m. Efficiency of perch reproduction in the Bratsk Reservoir is high enough due to the use of open spawning grounds, and normally good water levels in coastal spawning grounds. Fluctuations in water levels due to hydropower operations have little effects on successful spawning and survival of juvenile perch since they are less dependent on submerged aquatic vegetation compared to phytophillic species such as roach and pike (Ponkratov, 2015, Pastukov, 2015). Fecundity of perch in Bratsk Reservoir varies from 4.3 to 158 thousands eggs. Eggs in the form of long mesh type are laid on submerged vegetation and on underwater substrates. The eggs are large with the diameter of 2.0 -2.5 mm. Such way of laying eggs allows high survival rate of eggs and larvae. The spawning occurs once. The eggs development takes 14-24 days. At hatching time larvae are 6 mm long and present almost resorbed yolk, so they start moving actively at once and predating on plankton crustacea. The juvenile eats zooplankton and benthos during the first summer, and reaching 2-3 years old perch also prey on other fish (Popova 1971, 1979; Mamontov, 1977; Reshetnikov, 2003). Apart from the coastal areas of reservoirs with depths up to 15 m, which is a typical habitat for juvenile perch, a significant number of young fish of 8-12 cm length may be found in the central part of the expanded reservoir. For example, young perch caught on Kaltukskoye expansion above depths of 50-70 m. (Mamontov, 1977). Growth rate and maturation time of perch can vary greatly. In small and little feeding reservoirs perch hardly reaches 5 cm body length during the first year, by the age of 6 it reaches just 20 cm body length. In large lakes and reservoirs, in estuaries of large rivers, one year-old perch reach 12 cm, 5 year – 35 cm. Spawn of perch can be early in spring, after melting of ice: in February – March in the south, in May – June – in the north when the water temperature is 7-8 C. Male perch begin to mature at age 2+ with an average length of 13.5 cm and a weight of 75 g. Females begin to mature at ages 3 +. On average males mature at 2-3+ years and females at 3- 4+ years. By the age 5 all perch reach maturity. Good feeding conditions in the Bratsk Reservoir casues high abundance and good stock status of perch. If fish is not sufficient, perch easily shift to invertebrates (mainly benthos), abundance of

Document: Bratsk Reservoir Perch Fishery 2nd surveillance report page 44 Date of issue: November 2018 which in the Bratsk Reservoir is high, that favorably affects the growth of perch. Intensity of feeding and growth rate of perch by shifting from predator to invertebrate feeding remains at high level. The perch usually live in shallow areas, migrating in small groups looking for food and spawning places. In large lakes and reservoirs like Bratsk Reservoir some part of the perch population can enter tributaries for spawning, later return to the big reservoir for feeding. Seasonally, the largest perch migrate from the coastal zone to middle part of the reservoir (sometimes 30-40 kilometers) after spawning in spring-summer. There, they feed in surface waters quite far from the shore and winter in relatively deep places up to 30 m. This behaviour shows potential of perch to restricted migrations and intermixing. At the same time, younger fish are more sedentary and can spend al the year around in small inlets (Pastukhov 2015)" Growth and weight rates of Bratsk Reservoir perch are shown in Figure 3.6 below. In 2014, the perch caught in the fishery were between 9.6 and 29.0 cm long, belonging to age groups 1-10.

Figure 2. Growth of perch by length (left) cm and weight (b) g in the Bratsk Reservoir in 2014. (Ponkratov, 2015).

Linear growth of perch in 2002-2014 compared with the earlier period 1990-1998 did not change, indicating the stability of the biological characteristics of this species over the last two decades. The perch is the most abundant commercial fish of the Bratsk Reservoir. During the period from 1997 to 2014 in commercial catches perch met aged 1+ to 12+ years. Fish aged 3-4 years - an average of 61.4 % - predominate in commercial stocks of perch (Bobkov, 2013; Ponkratov, 2015). The exception is caused by the emergence of productive generation. For example, due to productive generation in 2001, 60.9 % of the number of commercial stocks of fish formed by the age of 2-3 years in 2003, and 68.4 % of the catch came from individuals of 4- 5 years in 2005. The average age of perch catches in different fishing gear was 3.7-3.8 years in 2014. Perch actively preys on young fish, including its own juveniles. Other fish species eat perch including pike, burbot, and Amur catfish. Bird predators include seagull, heron, cormorant, and osprey. In the Bratsk Reservoir perch compete for food mostly with roach (before transition of perch for predating) and coregonids (plankton feeding Baikal cisco and benthos feeding lacustrine whitefish), which previously were abundant in the reservoir and were supported mainly by hatcheries.

The assessment of stocks of all commercial fish in the Bratsk Reservoir is lead by Baikal branch of Gosrybtsentr, located in Ulan-Ude. With the aim of getting primary information Gosrybtsentr organizes research surveys, which take place at different parts of Bratsk Reservoir throughout the year. Other research support comes from the Bratsk branch of Baikalrybvod, (or the Baikal Fishery Enhancement Agency), which is part of a state-wide network of agencies operating to increase the fishery productivity of water bodies.Providing test catches they use 1-2 set of nets with different mesh size (14-80 mm) and minnow seine (20-50 m long, mesh size in cod-end 6 mm). They analyze species composition of fish catches, their size and weight characteristics (at least 10-15 individuals in each size group and 20-25 individuals in modal size groups) and carry out a full biological analysis of a part of the catch. During FBA sex, age, stage of maturity, stomach fullness and a range of other biological indexes are identified according to the Program of sampling (Anon., 2015), elaborated by Gosrybtsentr on the base of Russian standard method (Anon., 1990, Sechin, 1998). Ichthyological investigations are performed in the whole reservoir, also in the areas forbidden for commercial fishing, including spawning areas (V. Poroshin, personal communication). Gosrybtsentr and Baikalrybvod along with ichthyiological research, also monitor hydrological characteristics and temperature regime of the reservoir. Apart from information taken from the research catches they use data from commercial catches to assess the stock status. The following parameters are analysed based on collected samples:

• Dynamics of catches (diurnal, seasonal, year-by-year); • Fishing effort (periods when the fishing gear are used, number of fishing days; number of fish removals per day, construction of fishing gear; catch per gear, catch per day per fisherman, etc.); • Species composition of catches (by number, by weight and by type of fishing gear), taking into account their seasonal dynamics; • Size and age structure of catches; • Biological characteristics of main commercial species.

To account for removals of the recreational fishing, Gosrybtsentr researchers interview recreational fishers in different seasons. They collect information on stock composition, weight of caught fish, method, place and duration of fishing. The collected data are recorded in so called “recreational fisher cards”. Based on this information, Gosrybtsentr makes estimates on the annual sizes of recreational catches for the whole reservoir. The annual volumes of IUU catches are also accounted at the base of expert judgment.

Biological analysis uses individuals of each species from commercial catches to determines their age (Anon, 2015). As for perch, total number of fish analyzed in 2014 was 2523 individuals, and age was determined for 261 individuals. A total of 46,750 individuals of the perch of archival materials were analyzed for size and age composition for the period 1992-2013.

Document: Bratsk Reservoir Perch Fishery 2nd surveillance report page 46 Date of issue: November 2018 Among those species of Bratsk Reservoir, for which Gosrybtsentr sets standards of the Total Allowable Catch (TAC), are grayling, Baikal cisco and lacustrine whitefish. TAC is determined based on justification of optimal removals suggested by Tiurin (1967), according to which the appropriate level of commercial fish mortality should not exceed the natural mortality of dominant age classes in the fishery, 3 - 5 year old, approximately 30 % for most species. Russian scientists have effectively used these principles to manage freshwater stocks for many years in many water bodies.

For perch as well as for other low value species of the Bratsk Reservoir (bream, roach, Prussian carp, ruffe and others) researchers calculate Possible Catch, or Recommended Allowable Catch (RAC). The same methodology is used to determine RAC and TAC. However, compared to RACs, procedure of allocation of TACs is more complicated and includes additional discussions with the Federal Fisheries Agency and review by the State Ecological Expertise, an independent expert group.

RACs establishes biological reference points based on expected natural mortality of fish in dominant age classes, 3 - 5 year olds. Managers assume that fishing mortality cannot exceed this amount, defined as a percentage of the commercial stock. For perch, fishing mortality should not exceed 29% of the commercial stock, for roach no more than 26 %, for Prussian carp 25 %, and for bream 22 %. In this way, the remainder of the stock would be able to sustain the structure and function of the ecosystem within the reservoir (Tiurin, 1972).

Calculation of the stock status is conducted by scientists of Gosrybtsentr using data on the value and size-age composition of catches to calculate the virtual number of its population (Table 1). This age structured approach (bio-statistical method by Malkin & Borisov 2000) calculates the number of fish of each age group in the annual catch. The number of survivors of any age group can be found in the catches of following years when one generation after another consistently are caught. Further calculations sum each generation to estimate the stock size in a given year.

Table 1. Age composition of commercial catches of perch in Bratsk Reservoir (% of catch)

There is no accounting for natural mortality (M) because bio-statistical model applies only to stocks used in fishing, namely, those on the fishing grounds (Riker, 1979). The assessment method takes into account catches that are not registered in the official statistics. The volume of recreational and IUU catches are accounted for in the form of expert evaluations of scientists.

To determine the number of stock in view of not generations, which are not completely caugth, a regression method used by researchers, which takes into account a relationship between overall commercial quantities with the magnitude of caught part of it. The significance of the correlation coefficient was determined by the value of Temp. This given factor has a Student’s t-distribution with k = n - 2 degrees of freedom, when the null hypothesis is true.

According to data by Gosrybtsentr, the correlation coefficient between the catch and the stock of perch in 1992-2008 (N = 17) was 0.812, Temp - 5.3888> tcr - 2.9467 (the tcr was found in the table of critical points of the t-distribution at a significance level α = 0,01 and k = n – 2 degrees of freedom). Thus, the null hypothesis is rejected, the correlation coefficient differs from zero and X and Y are correlated, i.e. linearly related.

According to the regression equation (Figure 3) determinate between the catch and completely caught stock for 1992-2009, stock status for the period 2009-2014 was identified using data on catches of perch at the same years - 2009-2014.

Figure 3. The number of stock and catch of perch in 1992-2009.,(thsnds. Inds.).

Dynamics of received commercial stock allows scientists to predict the state of the stock by using trend for 2016 (Figure 4). The magnitude of reliability of approximation (R2) was 0.92.

Figure 4. The stock size of perch, thousands of individuals

Approximation of data on the dynamics of the commercial stock with a forecast for 2 years in advance, i.e., for 2019, gives the following results: in 2019 commercial stock of perch will be 45126.5 thousand individuals. Biomass of commercial perch stock - taking into account the average weight of 0,094 kg of one individual - will be 4416 mt

It is assumed that the amount of biologically acceptable withdrawal of fish from a water body must not exceed the rate of natural mortality in middle age. Under these conditions, the normal reproductive capacity is maintained and there is no risk of disruption of stock (Turin, 1972). Given the constancy of the rate of natural mortality of perch in the middle ages (0.29) the value of the possible catch installed by Gosrbycenter could reach 4416 * 0.29 = 1281 mt in 2019. Taking into account that perch mostly inchabit areas with depths less than 15 m, which area is minimum 182.5 thousand hectares (except for the areas in the upstream parts of the reservoir with poorly developed coastal water biotop). In 2015, the Ministry of Agriculture of the Irkutsk Region diverted for the 174 fishing parcels of the Bratsk reservoir 97.3 thousand hectares. In 2016, the tenders were held and in 2017 the actual area used as fishing parcels increased. Given this change, a part of the perch commercial stock is transferred from the category “reserve” to RAC. Due to the uncertainty with the size of the areas of fishing grounds, which will be used in 2019, the possible perch catch in 2019 is determined 1900 tons, although, potentilly, the stock allows to increase the harvest (Table 2).

Table 2. – Possible catch of perch in the Baratsk reservoir in 2019

Document: Bratsk Reservoir Perch Fishery 2nd surveillance report page 49 Date of issue: November 2018 Total catch in 2017 Possible catch in the Total area Possible catch in Areas of (official entire reservoir inchabited by fishing parcels in fishing plus perch (depths 2019 parcels, recreational under 15 m), thousand ha and IUU) thousand h S S mt Kg/h 15 kg/h mt 15 Kg/h mt th.h Th.h 182.5 53.0 1413 26.7 97.3 26.7 2598 182.5 26.7 4873

It should be noted that the commercial stock and thus the Possible Catch for 2019 are determined for the areas of the existing fishery. Based on calculations, it is 2598 mt. However, current RAC is 1900 mt. It takes into account capacity of fisheries, which were able to catch in 2017 only 1113.3 mt of catch. This figure is only 22.8% amount, which can be potentially allocated for fishing (4873 mt). Thus the actual catch of perch in the reservoir is much leass than the stock status allows, and can be increased about four-fold if the capacity of fisheries will allow. About the same situation with most of other commercial fish in the reservoir. Ecosystem Elements

Fish and the Bratsk Reservoir The Bratsk Reservoir is a man-made impoundment that covers 5,470 square kilometers of the Angara River north of Irkutsk, Russia. After completing the Bratsk dam in 1967, it took six years to fill the Bratsk Reservoir to its current storage capacity of 169.7 km3 of freshwater. Rising water levels displaced some local residents and agricultural lands. Today, the reservoir consists of two flooded valleys that created a large freshwater basin that does not contain sensitive habitats such as those for sponges or corals.

Hydrological changes impacted aquatic communities and change community composition of fish species. Native Siberian species adapted to riverine conditions, such as sturgeon, starlet, taimen, lenok, tugun, and char declined, while species suited more to lakes and reservoirs, such as perch and roach, increased. Biodiversity decreased and new alien species established niches in depleted communities of the artificial reservoirs (Ponkratov, 2014). Currently, there are 38 fish species and cyclostomes in the reservoir, of which 13 species are subject to commercial fishing.

The current Bratsk Reservoir has an average depth of 31 meters (m) and maximum depth of 155 m. It has an exchange rate of 1.82, this is the ratio of annual water volume to outflow. Managers control water levels by annual cycles of a winter-spring drawdown followed by summer-autumn impoundment. Reservoir levels also fluctuate due to weather patterns or needs of the power industry. The operation of the Angara HPP cascade (Irkutsk HPP, Bratsk HPP, Ust-Ilimsk HPP) has been performed in compliance with the “Main regulations on the use of aquatic resources of the Angara HPP cascade reservoirs.”

The level of the reservoir is characterized by a yearly cycle of minimum water level in April- May and the maximum levels in October-November (Sinyukovich, Martynov, 2003). The spring drawdown drains and freezes near shore areas. As a result, the coastal zone is virtually devoid of

Document: Bratsk Reservoir Perch Fishery 2nd surveillance report page 50 Date of issue: November 2018 aquatic vegetation that serves as spawning grounds and juvenile habitat for pike, bream, and roach that spawn in May-June. Perch is less dependent on submerged vegetation for spawning and a factor for its reproductive success. This annual variation of the water level adversely affects the natural reproduction of spring-spawning phytophilic fish species (especially pike) due to a lack of suitable spawning grounds for it (Bobkov, 2013). These changing water levels also negatively affect several autumn-spawning species such as Baikal cisco and lake whitefish (coregonids) that may not have enough gravel bottom habitat for spawning in shallow parts of the reservoir.

However later spawners, or multiple spawners, such as Prussian carp and catfish, find more favorable habitats as reservoir water levels and associated aquatic vegetation increase over the summer. As a result, abundance has increased for multiple-spawning Prussian carp, as well as catfish and carp. Spawning in late June – early July, these fish take advantage of rising water levels (0.5 m or more) to secure good spawning habitats in flooded areas. Abundance of species such as bream which depend on shallow water habitat (4-10 m deep) have stabilized. However, in general, perch and roach are the dominant fish species for the Angara reservoirs.

The efficiency of fish breeding in several areas of Bratsk Reservoir is negatively affected by the impact of industrial wastes such as those of the Usoliekhimprom, Angarsk Metallurgical Plant, Sayanskkhimplast, Bratsk Aluminium Plant, Bratsk Timber Processing Plant and others (Pastukov, 2015). These factories discharge a range of pollutants including mercury, organic matter content, oil products, and phenols). As a result, parts of the Bratsk Reservoir water are characterized as "poorly polluted" (Anon., 2012). Moreover, researchers have found measureable levels on mercury (Hg) in some fish, including perch (Pastukov, 2015).

Fishery Habitat Perch (and roach) prefer habitat with water depths up to 15 m. Most intensive fishing activities occur in these shallow areas close to settlements with good road access. Some scientists have suggested expanding the fishery to more remote habitats in order to increase yield. HCRs limit fishing effort to maintain biologically acceptable catch that is based on a ratio of catch to the stock. For pech ratio is 0.29, but in some years yield can reach 0.33 per cent of the stock. These levels of intensive fishing may be of concern to some local stocks.

Bratsk Reservoir Fish Bratsk Reservoir contains about 37 known species of fish, plus one hybrid. Fishery managers have defined reference points for 13 species and listed seven fish or lampreys as endangered or threatened species. See Table 3.

Primary Species

Roach (Rutilus rutilus) плотва Roach is in the Family Cyprinidae. It mostly inhabits shallow, littoral waters with vegetation that provides protection to larval and juvenile fish and food for adults. Roach eats plant material, bottom-dwelling (benthic) invertebrates, and plankton. Young fish feed mainly on plankton, while the mature fish feed mainly on benthos. It may shift from littoral to pelagic habitats and between benthic food and zooplankton when abundance of a specific food item is high or to avoid predators and/or competition. Roach may take short spawning migrations and stay in deep parts of the reservoir during the winter. They breed among dense submerged vegetation along flooded parts of the shoreline and deposits pale yellow eggs that attach to vegetation and tree roots. Occasionally it breeds with bream Abramis brama to produces fertile roach/bream hybrids. Roach harvest peaked in the early 1970s but declined in the 1990s during a period of economic difficulties in Russia. Since 2006 roach catch and catch per effort have been increasing along with strong control and management of the fishery.

Bream (Abramis brama) Лещ Bream represented about 11 % of the commercial catch of fish in Bratsk Reservoir in 2012. Fishery managers introduced bream to the reservoir between 1962 – 1971 from stocks in Novosibirsk and Kazakhstan. After the new stock spawned successfully and spread across the reservoir, commercial fishing for bream began in 1987 (Ponkratov, 2013) Bream approach spawning areas near the shore in March and April and stay in these shallow zones until spawning takes place in June with rising water temperatures. Mature fish concentrate in areas less than 10 m deep and (55-60 %) of the harvest takes in June and the first half of July. Other harvest takes place in August and September in the Oka River region and fishermen fish from the bank at depths up to 36-40 m. There is little juvenile by-catch. Bream spawn on submerged vegetation and wood including flooded branches, timber, and stumps. Bream in the Bratsk Reservoir becomes sexually mature at the ages of 4 -5 + years and males mature first. At this time adult males average about 27 cm and weigh 280 grams. Later maturing females reach about 33 cm and weigh 870 grams. Despite significant fluctuations in commercial catch the trend in bream harvest shows an increase in the annual catch to 116.8 tons in 2012 compared to an expert assessment of 210 available tons. Expert assessment includes additional estimates for recreational and illegal or unreported catch.

Prussian Carp (Carassius gibelio) карась Prussian carp consists of about 9 % of the commercial catch and represents a MSC primary main species. Amur carp represents less than 1% of the catch and is considered an MSC primary minor species. Most of the harvest occurs in the shallow bays of Balagansk fishing area and the upper

Document: Bratsk Reservoir Perch Fishery 2nd surveillance report page 53 Date of issue: November 2018 reaches of the Oka River. Prussian carp are omnivores, eating plants, insects such as mosquito larvae, small crustaceans, zooplankton, and benthic detritus. The fish matures early, reaching sexual maturity at age 1 + in males averaging 11.0 centimeters (cm) in length. Carp spawn in shallow depths of 0.1 - 0.5 m on substrates that include submerged vegetation, wood branches, sunken logs, and stumps covered by rising water levels. Spawning begins in June and continues through August and depends on water levels and available spawning habitat. Catches have increased since 2001 with a rapid rise since 2007. Data from 2003-2009 show that most of the catch (66.2 - 82.6%) resulted from fish aged 4 - 5 years. In 2012 the average age in commercial catches was 5.7 years. Most of the catch takes place during mass spawning in the spring, followed by late summer harvest from July to October. During late summer Prussian carp represents by-catch from perch and roach fisheries. Primary Minor Species

MSC defines primary minor species as managed stocks that comprise less than 5% of the catch of the UoA. In this context, in this context managed stocks refer to fished stocks operating under a RAC or TAC (*). Bratsk Reservoir minor species include: Amur carp, peled, Burbot, Amur catfish, pike, dace, ruffe, grayling, Baikal cisco. Minor species are mostly by-catch of targeted perch and roach fisheries. And for these species scientists do not set RAC based on the same stock assessment models used for perch, roach, bream, and Prussian carp. Rather, they calculate an average percentage of by-catch in the perch plus roach fisheries and use this value to estimate RAC. For grayling and Baikal cisco (omul) scientists set a TAC. These fish are most often distributed in low numbers across the reservoir and tributaries and fishing has little affect on their populations relative to other factors determining their reproductive success. Introduced species include peled and cisco and their populations depend on artificial reproduction. While these fish do not represent significant portions of the commercial catch, fishers keep them to supply food to local populations. So they are not considered unwanted catch. Rather, unwanted catch may refer to juveniles of target and primary main species. Endangered, Threatened, and Protected (ETP) species

Among the Irkutsk Redlisted species those inhabiting the Bratsk Reservoir include: Far Eastern brook lamprey, Siberian sturgeon, starlet, taimen, lenok and tugun (Matveev et al, 2009). All they are reported for upstream parts of the reservoir with more riverine conditions – in Usolsk and Balagansk districts. However, fishermen use trapnets (the UoA) much less in these riverine, upper watershed districts than in downstream Bratsk district with more lacustrine conditions. For instance, in Usolsk district only 0.6 % of total catch is taken by trapnets. Moreover, lampreys, with their narrow body, are too small to be caught by trapnets with meshsize of 18 mm or larger, the minimum size allowed by fishing rules (in fact only trapnets with meshsize 22 mm of more are used). Lenok is a reophylic species, which inhabit stream and cannot occur in the reservoir. Therefore we considered that interaction of these species with trap nets in Bratks district is negligible and did not analyse them in framework of this certification. But the other four species can be caught in the trap nets. Although these species are not identified in commercial catches, fishers and fish inspectors occasionally mentioned them in stakeholder interviews. Ecosystem

Document: Bratsk Reservoir Perch Fishery 2nd surveillance report page 54 Date of issue: November 2018 Ecosystem changes in the Bratsk Reservoir can be measured at several trophic levels such as those for zooplankton, benthos, and fish. Since the 1970s, scientists have conducted research studies to characterize communities of zooplankton and zoobenthos. These include studies from 1974-1978, 1992, 2006, 2007, 2009, and 2011 that enable researchers to identify patterns and trends in these lower trophic orders (Pastukov, 2015). Figure 3.3 shows the distribution of 22 sampling stations across Bratsk Reservoir in an extensive 2011 aquatic monitoring survey.

Results describe zooplankton communities in three major groups: rotifers, copepods, and clodocera (Basharova, 2005). Plankton reach maximum development in mid-July and August and more than 90% of their production comes during the five summer months free of ice (Basharova, 1978).

Zoobenthos species in depths of 4 to 16 m include: oligochaetes (Oligochaeta), chironomid larvae and pupae (Chironomidae), bivalves (Bivalvia) and gastropods (Gastropoda), ostracods (Ostracoda), freshwater hoppers (Gammaridae), biting midge larvae (Ceratopogonidae), leeches (Hirudinea). Oligochaetes and chironomid larvae were the prominent group of benthos (Erbaeva et al 1999)

Sampling of zoobenthos in August 2011 was made mostly at depths of 5 – 6 m, typical of habitats of benthic feeding fish. This is confirmed by measured performances of fishing nets, showing that largest catches were observed at depths of 2-7 m. At depths greater than 10 m nets were empty and they got only a few specimens of fish. In shallower depths of 1 to 3 m, fewer fish and benthos resulted from large amounts of woody debris on the bottom and lack of good sediment for benthic communities in flooded forest areas (Pastukov, 2015).

The changing hydrobiological regime of the reservoir favors fish species that feed on chironomids, oligohaetes and plants such as roach, perch and carp, and to a lesser extent, bream and ruffe. At the same time scientists noted declines in commercial stocks of fish that feed on molluscs, such as whitefish and sturgeon) and these species have declined sharply in recent decades (Pastukov, 2015).

Based on research results over the last 40 years, scientists attribute ecosystem changes to several factors (Pastukov, 2015) including:

1. Logging and forest operations. Large amounts of cut timber floating in the reservoir increase organic content and modify plankton communities. 2. Eutrophic waters. Inputs of nitrogen and phosphorous from land based pollution results in low oxygen or eutrophic waters in some bays. 3. Changing water levels. Reservoir water levels rise and fall by as much as 7 m over a typical years. This periodic flooding and drying out of coastal areas submerges plants and woody debris, destroys clutches of fish eggs, and modifies habitats for benthic organisms. These changes affect all levels of the trophic structure. 4. Water temperature. Rising water levels and loss of riparian vegetation also affect water temperatures of communities of zooplankton. 5. Industrial pollution. Several studies have found elevated levels of mercury in tissues of fish, molluscs, and plankton. Although ecosystem effects of mercury and other heavy metals are

Document: Bratsk Reservoir Perch Fishery 2nd surveillance report page 55 Date of issue: November 2018 difficult to determine, they likely have subtle effects on the trophic order and human health. But pollution does not represent acute threats to fish stocks.

Impacts of fishing on the ecosystem None of the studies mentioned in the Pastukov report identify fishing as a cause of ecosystem changes. Scientists observe different feeding patterns for perch, roach, carp, and bream as these fish eat different amounts of plant material, detritus, zooplankton, benthic organisms, and other fish. And as various factors affect these communities, fish communities can also changes. For example both roach and perch consume zooplankton, but roach consumes more aquatic vegetation and detritus and relatively more bivalves and molluscs, while perch eat more amphipods and chironomids. But researchers conclude there is adequate food for all fish species and species can coexist that feed on the same prey. For these reasons, we conclude that fishing has little impact of ecosystem structure and function, especially compared to the other significant impacts in the reservoir (Pastukov, 2015). Management System The current Russian Federation became independent of the former Soviet Union in 1991. As a federation, it consists of numerous jurisdictions with various levels of autonomy. The legal system is based on civil law system with judicial review of legislative acts. The federal government has centralized authority in Moscow, where final decisions are made. The fisheries management system consists of complex levels of authority for management and research, with final decisions centralized in Moscow.

The current management system is regulated according to the federal law “On Fishery and Conservation of Aquatic Biological Resources”. This law gave the government the authority to assign fishery sections to individual leaseholders for up to 20 years, and freshwater fisheries management was entrusted to the regional executive authorities. This regulation replaced the previous more centralized fishery management system, when most of decisions were accepted in Moscow, with a much more responsive and effective regional system. The current system is widely viewed as an improvement for fisheries management as it can react more quickly to any changes of fishery situation. The Federal Fishery Agency (FAR) and its Gosrybtsentr branches manage much of the fishery. But the regional Ministry of Agriculture of Irkutsk Province distributes quota among users and the Baikal Scientific Commercial Fisheries Council (BSCFC) provides a mechanism for more local participation in fishery decisions.

Federal Governance Federal Fishery Agency

Federal Fishery Agency (FAR) (Федеральное агентство по рыболовству or Federal'noe Agentstvo po Rybolovstvu, http://fish.gov.ru) is an executive authority of the Russian Federation, established by the Presidential Decree No. 724 issued 05.12.2008, by converting the pre-existing Russian Federation State Committee for Fisheries (Rossrybolovstvo). The President issued the Decree No. 863 on 12.30.2008, which established that FAR reports directly to the Government of Russian Federation. RF Government Decree of 06.11.2008 No. 444 approved the current Regulations governing the FARs operations. The Federal Fisheries Agency is a part of Ministry of Agriculture.

Document: Bratsk Reservoir Perch Fishery 2nd surveillance report page 56 Date of issue: November 2018 FAR interacts with various agencies at the federal level while controlling its territorial departments. It is responsible for over sight of departments under its jurisdiction, which define the rules and the annual Total Allowable Catches (TAC) or Recommended Allowable Catches (RAC), and the areas allowed fisheries. FAR also conducts communication and coordination with foreign government agencies, international committees and international organizations on issues of fisheries, policy and technical programs related to innovative technologies in the fisheries complex, and prepares federal-level and agency-level reports on the fishing industry. The head of FAR supervises deputies and departments, which are responsible for the management of the fishing fleet, protection and rational use of resources, reproduction of marine resources and their habitats. FAR is also responsible for monitoring water resources and stocks of commercial species and control over the distribution of TAC/RAC among the users. FAR also conducts research and engineering, directs federal fishing vessel and fishing ports, and controls the activity of artificial breeding. Departments within FAR include the Angara-Bailkal Territorial Administration (ABTU), Gosrybtsentr, Baikalrybvod, and the Public Council.

Angara-Baikal Territorial Administration (ABTU) of FAR

FAR has territorial departments in all regions of the Russian Federation, which have been created in order to accelerate the implementation of many of the functions of the FAR on the level of Russian Federation subjects. Angara-Baikal Territorial Administration of FAR (ABTU) (Ангаро-Байкальское территоральное управление ФАР, АБТУ) is the local management and enforcement arm of FAR for Republic of Buruatia, Irkutsk Province and Zabaikal Province, which is located in city of Ulan-Ude. ABTU has departments in all administrative discricts. In the fishery under assessment, Bratsk department of ABTU is head by Aleksandr Ivanov. ABTU has final approval of fishing concessions and in-season fishery management regulation actions (to open and close fisheries). They give fishing companies permission to harvest, monitor fishing companies and processors to ensure regulation compliance. ABTU posts all approved management decision related to the region.

Gosrybtsentr of FAR

FAR includes a network of scientific research organizations conducting research and development of both applied and fundamental science in accordance with the program entitled “Scientific and engineering support of the Russia’s fisheries industry.” FAR has 15 scientific- research organizations under its direct supervision. One of these institutions is the Federal State Fisheries Research Institute, Gosrybtsentr, (Федеральное государственное бюджетное научное учреждение Государственный научно-производственный центр рыбного хозяйства). The Gosrybtsentr regional branch located in Tiumen city, with the Baikal branch in Ulan-Ude city. It was founded in 2008. In city of Bratsk, Stanisiav Ponkratov, the author of many of the technical reports this assessment is the Gosrbycenter representative responsible for Bratsk Reservoir, the area under certification. It is responsible for state-level monitoring of stocks and additional resources and for rational and efficient use of bio-resources. The Gosrybtsentr has legal status as federal state unitary enterprises. And its activities are regulated by charters approved by FAR.

Document: Bratsk Reservoir Perch Fishery 2nd surveillance report page 57 Date of issue: November 2018 In the Baikal region, Gosrybtsentr conducts research of aquatic biological resources and monitors the status of commercial species, including perch. It prepares annual forecasts of commercial species and their TACs or RACs. Each October Gosrbycenter issues forecast for recommended catch of perch for two years in advance. The forecast is developed based on proportion of spawning stock to be caught to maintain maximam sustainable yield (MSY). Annual forecasts by Ulan-Ude branch of Gosrbycenter for recommended catch are sent to Gosrbycenter (Tiumen) for approval and then sent to VNIRO.

All-Russia Institute for Fisheries Research and Oceanography – VNIRO.

All-Russia Institute for Fisheries Research and Oceanography VNIRO (Всероссийский научно- исследовательский институт Рыболовства и Океанографии, ВНИРО or Vserossiiskii nauchno-issledovatelskii institut rybolovstva i okeanografii) of Moscow is the head institute in the field of fishery related research. It examines and approves fishery through it Scientific Council. Following the adoption of the forecasts, VNIRO sends them to FAR for approval and implementation. The annual forecasts serve as the basis to organize the fisheries in the region.

Regional Governance Baikal Scientific Commercial Fisheries Council (BSCFC)

Baikal Scientific Commercial Fisheries Council (BSCFC) (Байкальский научно-промысловый совет) is an independent council made up of a FAR representative, state agencies related to nature resources management, scientific research institutes, non-profit commercial associations of commercial fisheries, and minority people representatives. The personnel composition of the BSCFC is approved by order of FAR based on the recommendations of the Russian Federation territorial subject. However, half of its members must be either from scientific or similar fish conservation or natural resources agencies. The council has the authority to engage other competent authorities, interested parties (or stakeholders) as needed, upon approval of a vote of its members. Meetings are held at least twice a year. Any interested party can attend BSCFC meetings to express opinions and participate in the discussions. Central to the responsibilities of the BSCFC is the compilation of scientific information concerning the management of regional aquatic bio-resources for submission to FAR for final approval. In addition, it reviews and submits its recommendations on fisheries regulations, construction of fish hatcheries and the recommendations for the distribution of quota among its subjects.

Fisheries Council of Ministry of Agriculture of Irkutsk Province

Fisheries Council of Irkutsk Province (Рыбохозяйственный Совет при правительстве Иркутской области) was organized 8 July 2015 (http://www.irk.aif.ru/politic/rybohozyaystvennyy_sovet_sozdan_v_irkutskoy_oblasti). The Fisheries Council is an advisory body established to discuss matters related to management of fishing, development of commercial fisheries and conservation of aquatic biological resources. The Council includes representatives of the government, scientific and public organizations. The Acting Minister of Agriculture of Irkutsk Province heads the Council. Within the framework of this Council, experts discuss issues such as the development of aquaculture in the region, compliance to legislation on the conservation of aquatic biological resources, prevention of

Вылов неполовозрелого окуня в 2017 г. С.Ф.Понкратов Окунь относится к промысловым рыбам с коротким жизненным циклом и ранним половым созреванием. Интенсивный вылов короткоцикловых рыб связан прежде всего с тем, что плотные концентрации обеспечивающие эффективный лов, они образуют не постоянно, а в отдельные сезоны, обычно в период нереста. Эти виды относятся к группе неохраняемых видов и правила регулирования рыболовства на них фактически не распространяются. Так, для окуня Братского водохранилища в Правилах рыболовства для Байкальского рыбохозяйственного бассейна не установлена минимальная промысловая мера, то есть не определены размеры и возраст молоди.

При подготовке отчета были использованы данные из ихтиологических сборов 2012-2017 гг. БФ Госрыбцентр по стадии зрелости окуня возрасте 1+ - 7+ лет в период размножения, в количестве – 988 экз. Наступление половой зрелости у самцов окуня приходится на возраст 2+, при достижении наименьших размеров (длины 12,0 см и массы 30 г), половозрелые самки в этом возрасте составляли 10,4%, самцы – 59,7% (таблица 1).

Таблица 1 – Созревание окуня (по материалам 2012 – 2017 гг.)

В возрасте 3+ значение половозрелых самок увеличивается до 58,6%, самцов – до 81,7%, в этом возрасте созревает свыше 50% рыб. В возрасте 5+ процент взрослых самцов и самок составлял 93,7%, к 6 годам созревают 100% рыб (Рис.1).

В возрасте 2+ созревает 40,0 самцов и самок. В возрасте 3+ созревают – 58,6% самок и 81,7% самцов. Принимается, что допустимая промысловая мера равна средней величине этого показателя у возрастной группы рыб, для которой характерно массовое половое созревание самок. Под массовым половым созреванием понимается тот случай, когда половозрелыми оказываются 50% самок и более [1]. Таким образом в Братском водохранилище к молоди (неполовозрелым рыбам) относятся особи в возрасте 1+ и 2+, а минимальная промысловая мера начинается с размеров особей в возрасте 3+. В таблице 2 приводится длина окуня Братского водохранилища в возрасте 3+ в 2012 – 2017 гг.

Таблица 2 – Промысловая длина окуня в возрасте 3+ в 2012-2017 гг. Размеры 2012 2013 2014 2015 2016 2017 Средняя Длина, см 15,4 15,7 15,3 15,7 15,9 15,8 15,6 Масса, г 66 63 65 67 73 68 67

Средняя длина окуня в промысловых уловах в возрасте 3+ составила 15,6 см, с учетом того что в возрасте 2+созревают 40% самцов и самок, за минимальную промысловую длину принимаем 15 см, особи с длиной менее 15 см относятся к молоди. Осенью 2016 г. были проведены торги на аренду рыболовных промысловых участков (РПУ) на Братском водохранилище. До этого участки были использованы пользователями без официальных соглашений. В 2017 г. промысел производился или на новых промысловых участках (три пользователя) или на измененных участках (пять пользователей). Места установка ставных неводов на новых местах использовалась в качестве альтернативной меры для снижения прилова молоди рыб. При установке ставных неводов избегались участки в вершине заливов, небольшие заливы в крупных заливах – места концентрации молоди. В таблице 2 приводятся данные по значению в промысловых уловах молоди окуня.

Catches of main primary species (roach, bream, Prussin carp) in 2017 Вылов молоди основных промысловых видов рыб (плотва, лещ, карась) в 2017 гг. В. Юрин При подготовке отчета были использованы данные из ихтиологических сборов 2012-2017 гг. БФ Госрыбцентр по стадии зрелости рыб в возрасте 2+ - 6+ лет в период размножения, в количестве: плотва – 504 экз., карась – 693, лещ – 275 экз. Принимается, что допустимая промысловая мера равна средней величине этого показателя у возрастной группы рыб, для которой характерно массовое половое созревание самок. Под массовым половым созреванием понимается тот случай, когда половозрелыми оказываются 50% самок и более [1]. Осенью 2016 г. были проведены торги на аренду рыболовных промысловых участков (РПУ) на Братском водохранилище. До этого участки были использованы пользователями без официальных соглашений. В 2017 г. промысел производился или на новых промысловых участках (три пользователя) или на измененных участках (пять пользователей). Места установки ставных неводов на новых местах использовались в качестве альтернативной меры для снижения прилова молоди рыб. При установке ставных неводов избегались участки в вершине заливов, небольшие заливы в крупных заливах – места концентрации молоди. Темпы полового созревания плотвы. Наступление половой зрелости у самцов плотвы приходится на возраст 2+, половозрелые самцы в этом возрасте составляли 38,9%, все самки, по нашим данным, в этом возрасте неполовозрелые (таблица 1).
