1 Introduction The purpose of the annual Surveillance Report is fourfold: 1. To establish and report on whether or not there have been any material changes to the circumstances and practices affecting the original complying assessment of the fishery; 2. To monitor the progress made in improving the score of those performance indicators that were scored as below “good practice” (a score of 80 or above) but above “minimum acceptable practice” (a score of 60 or above) – as captured in any “conditions” raised and described in the Public Report and in the corresponding Action Plan drawn up by the client; 3. To monitor any actions taken in response to any (non-binding) “recommendations” made in the Public Report; 4. To re-score any Performance Indicators (PIs) where practice or circumstances have materially changed during the intervening year, focusing on those PIs that form the basis of any “conditions” raised. Please note: The primary focus of this surveillance audit is assess changes made in the last year. For a complete picture, this report should be read in conjunction with the Public Certification Report for this fishery assessment and the subsequent annual surveillance audit reports. 2 General Information 2.1 Certificate Holder details Fishery name Louisiana Blue Crab Unit of assessment Louisiana Blue Crab Date certified 9th March 2012 Date of expiry 8th March 2017 Surveillance level & type Level 6: On-site site visit.

3 Background 3.1 Changes in the management system There have been no changes in the management system since the previous annual audit. The FMP was last up-dated in November 2014 (http://www.wlf.louisiana.gov/sites/default/files/pdf/page/37762- fishery-management-plans-marine/finalbluecrabfmp11-7-14.pdf) 3.2 Changes in relevant regulations Although some changes are under discussion (closed season) no new regulations are in effect. The Escape Ring regulation becomes effective in 2017. 3.3 Changes to personnel involved in science, management or industry Following the election of new Governor, the LDWF Executive team changed. However, none of the changes affected the day-to-day management of the blue crab fishery. 3.4 Changes to scientific base of information including stock assessments During the surveillance visit, the Client provided the audit team with a draft copy (subsequently confirmed) of the most recent stock assessment for blue crab in Louisiana waters (LDWF, 2016). This stock assessment uses the same methodology as previous years (the Collie- Sissenwine catch-survey analysis (Collie and Sissenwine, 1983)), and includes stock survey and catch data for 2015. The assessment model is appropriate for data-moderate stocks such as Louisiana blue crab and has been used extensively in a wide range of stock assessments where a full age-structure is not available. The model requires a time series of annual abundance indices for juvenile and adult life stages, a time series of annual harvest estimates as individuals, an estimate of instantaneous natural mortality (M), and the relative selectivity of the juvenile and adult life stages to the survey gear. Indices of abundance are derived from the LDWF fishery-independent marine inshore trawl survey. Landings are taken from National Marine Fisheries Service (NMFS) statistical records for the period 1968-1998, and the LDWF Trip Ticket Program for the period 1999-2015. The assessment model provides estimates of exploitable biomass and recruitment to the Louisiana blue crab stock for 1968- 2015. Annual fishing mortality is estimated, but is not available for the last year of the time- series. The output of the model allows an assessment of stock status in relation to pre-defined reference points. The existing Louisiana blue crab data does not allow reliable estimates of maximum sustainable yield (MSY). Precautionary limits to fishing were established in an earlier assessment (West et al., 2011). These require that exploitable biomass does not fall below the three lowest levels observed (1968-2009) where the stock demonstrated sustainability (i.e. no observed declines in recruitment over a wide-range of exploitable biomasses). This is equivalent to maintaining the stock above a limit spawning potential ratio (SPR; Goodyear, 1993). The equilibrium SPR corresponding with the exploitable biomass limit is estimated to be 19.7%, which is equivalent to specifying the limit spawning stock biomass (SSBlimit) as 17.1 million pounds i.e. the average of the three years with the lowest biomasses (1968-2009) in which the stock demonstrated sustainability. The equivalent fishing mortality rate limit (Flimit) is estimated as 0.96 years-1. The biomass target reference point SSBtarget is defined as SSBlimit×1.5, or 25.7 million pounds. This biomass is achieved when there is an equilibrium SPRtarget of 29.6% and Ftarget of 0.74 years-1. The latest stock assessment shows that for the last year when estimates of both F and SSB are available (2014), SSB was at, or just below, SSBtarget (Figure 1), and that F was 0.97 x Flimit (Figure 2). On that basis, it can be concluded that, in 2014, SSB was above the point at which recruitment would be impaired, and that SSB was at the target level. In comparison, the model showed that SSB was at SSBlimit, i.e. overfished, despite having been at or above SSBtarget for the previous 8 years, and notwithstanding that F was below Ftarget (Figures 1 and 2).

Figure 2: Estimates of fishing mortality from the catch-survey model for Louisiana blue crab relative to management benchmarks

In 2015, the SSB estimate is below SSBlimit (0.83 x SSBlimit). However, as the model does not provide an estimate of F for the current year, there is no point available for 2015 on the phase diagram (Figure 3). Notwithstanding this point, the conclusion from the SSB and F estimates in 2014 and the SSB estimate in 2015 is that there is overfishing and the stock is overfished. Figure 3: Phase diagram of estimates of exploitable biomass and fishing mortality for Louisiana blue crab. The yellow circle represents the last year of data pairs, and the yellow triangle represents the biomass estimate for 2015.

Although recruitment levels over the last few years are lower than observed previously in the time series, recruitment has not declined significantly since SSB dropped below TRP, and indeed showed a slight increase in 2015 (Figure 4).

Due to the change in stock status, we determined to re-score PI 1.1.1 (Table 6). As the most recent stock assessment estimated that SSB was lower than SSBTARGET in two of the last four years, we concluded that the stock was not at or fluctuating around its TRP and PI 1.1.1 SG80 SIb was not met. On reviewing the evidence in relation to PI 1.1.1 SIa and after consideration of: (i) the biology of the target species; (ii) the limited difference between the TRP and LRP; and (iii) the previous recovery of the fishery from similar levels, we concluded that it is likely that the fishery is above the point where recruitment would be impaired and met SG60a. The score of 60 for PI 1.1.1 led to a new condition (7) being placed on PI 1.1.1 (Section 5.7). As PI 1.1.1 failed to score 80, we had to score PI 1.1.3 (Table 7). The score for PI 1.1.3 is 80. 3.5 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) No changes. 3.6 TAC and catch data Table 1: TAC and Catch Data TAC Year NOT Amount NOT APPLICABLE APPLICABLE UoA share of TAC Year NOT Amount NOT APPLICABLE APPLICABLE UoC share of Year NOT Amount NOT APPLICABLE TAC APPLICABLE Total green Year 2015 Amount 41.28 million pounds weight catch by Year 2014 Amount 43.30 million pounds UoC Fishery managers do not establish a TAC. Since 1997, commercial landings of blue crab in Louisiana have remained above 40 million pounds per year, with the exception of 2005, 2010, and 2013 (Figure 5). The highest reported landings of 53.5 and 54.7 million pounds were in 1988 and 2009, respectively (LDWF 2016).

A number of the conditions were redefined after the second surveillance audit in 2014. Maintenance of the MSC certificate has been contingent on the fishery progress in meeting those conditions. It is usual for the 4th surveillance to include the site visit for the recertification process. However, as matters now stand, the client has decided not to seek recertification of the fishery. Unless the situation changes, the catch from the fishery will not be certified after March 8th 2017. 4.2 Scope & History of the Assessment 4.2.1 History The certified fishery is for Blue Crab (Callinectes sapidus) in the State Waters of Louisiana, FAO statistical area 31, using baited traps. The fishery was certified according to the MSC standard on 9th March 2012 after an assessment that commenced in July 2010. The fishery was originally certified by Scientific Certification Systems (SCS), that also carried out the first annual surveillance audit.1 The client

changed the Conformity Assessment Body (CAB) in February 2014.2 The subsequent two annual audits (20143 & 20154) were completed by Intertek Fisheries Certification (IFC). In September, 2015 Acoura Marine acquired the IFC fisheries certification portfolio. Subsequently, the client confirmed Acoura Marine as it’s contracted CAB for the blue crab fishery. Acoura Marine confirms that the fishery remains in scope. There is a single Unit of Certification (UoC). In the initial certification the scores for the UoC were as in Table 3.

As in the two previous audits, the former was Team Leader. 4.2.3 Date & Location of surveillance audit This site visit was held in Baton Rouge, Louisiana from the 12th-13th May 2016. 4.2.4 Stakeholder consultation & meetings The audit was announced on the MSC web site on 5th April, 20165. Sixteen identified stakeholders were informed of the up-coming surveillance audit by email. The auditors did not receive any response from stakeholders. On the first day of the site visit, a full morning meeting was held with the client in Baton Rouge (Table 4). During this meeting, there was a thorough revision of the fishery, with emphasis on stock status and the progress being made to satisfy the conditions to the certification.

Client action Revised Client Action Plan (after 2nd Annual Surveillance Audit) plan At the third annual surveillance audit, LDWF will provide the formal Blue Crab Fishery Management Plan. The FMP will have been reviewed at public meetings and approved by the Crab Task Force and the Assistant Secretary for Fisheries, Louisiana Department of Wildlife and Fisheries. At the fourth annual audit, LDWF will present the Blue Crab Fishery Management Plan, in which the harvest strategy for the Blue Crab fishery will reflect target and limit reference points. Progress on Minor non-conformance. By the second surveillance audit provide evidence that the LWFC has incorporated in an official document all elements of the Condition revised client action plan, including methods used to address responsiveness to the state of the stock. [2013] Progress on The uncertainty remains as to whether the fishery meets the SG80 scoring issues and whether “an approved Fishery Management Plan is in place that Condition supports the recommendations of the stock assessment” i.e. whether or not there is a protocol for taking management action should reference levels [2014] be exceeded has been formally adopted. While we consider that the Resolution is a step in the right direction, our preference is for the process to be formalised in a FMP that has been discussed with and verified by stakeholders. This is important as it may be concluded from the most recent stock assessment that there are signs of overfishing and the potential for the stock as a whole to be overfished, although the situation may be variable by individual fishing areas. Given that our conclusion is that the client remains behind target in the second year, while progress has been made with the client actioning a wide variety of activities, the question is whether or not the harvest strategy is appropriate to achieving the management objectives expressed in the target

and limit reference points i.e. does the revised resolution satisfy the condition. At this stage we cannot conclude that the condition has been met. While the stock appears to be in good condition, and typically in the past there have been marked fluctuations in abundance, it may be the case that some actions may be needed and the harvest strategy should be adequate and able to respond in a timely manner. Taking this conclusion forward, this would imply that the client has remained behind target in two consecutive years and as specified in MSC CR v1.1 para. 27.22.9 “In the event that the CAB determines that progress against conditions is inadequate and/or a condition is not back ‘on target’ within 12 months of falling ‘behind target’, the requirements of 7.4 (suspension or withdrawal) shall be applied” i.e. Para 7.4.3 “A CAB shall suspend a fishery certificate if a certificate holder.7.4.3.2 Has not made adequate progress towards addressing conditions”. However, MSC CR v1.1 Para 27.22.10 states “In the event that the requirements of any condition are changed, the CAB shall provide written justification for this in the Surveillance Report”. While MSC CR v1.1. para 4.11 that covers the situation where there is a change in CAB states in para 4.11.4.10 b ii “All conditions and/or non-conformities raised by the current CAB shall remain applicable, unless they are closed or revised as a result of an on-site audit by the succeeding CAB, and the actions taken are justified and documented”. MSC CR v1.1 c. 27.11.3.2 requires that a “CAB not accept a client action plan unless it is satisfied that the conditions are both achievable by the client and realistic in the period specified”. In our opinion, while PI 1.2.1 was scored correctly and a condition was required, the initial time scale and the client commitment to the creation of an FMP in one year was neither realistic nor achievable. This has led to what may be considered a piecemeal approach, with actions undertaken to satisfy the MSC condition rather than respond to an orderly and effective process that seeks to ensure that the fishery is sustainable according to the MSC standard. We conclude that the original milestones set for the condition were not achievable in the period specified. On that basis we have redefined the condition. In the meantime we consider that the work undertaken to-date means the client is on-target. Progress on The Louisiana Blue Crab Fisheries Management Plan (LDWF 2014) was posted on the LDWF web site after approval by the Assistant Secretary for Condition Fisheries, LDW. [2015] The FMP (p. 11) includes the text of the Resolution quoted above (under 2014 progress) as adopted by LWFC. The text of the Resolution is also included in the FMP (p. 36) as an element of fisheries management policy. The FMP is a comprehensive and well-organized document that provides background information on the stock and fishery, and outlines management issues and approaches. Prior to its adoption, LDWF officials made a formal presentation of the FMP to the Crab Task Force and the LWFC. Subsequently, the FMP was posted on the LDWF web site for public comment. Neither activity led to substantive feedback or identification of areas for concern. Consistent with the existing process for responding to comments and peer reviews on stock assessments, any feedback or concerns would have been met by a formal public response prior to final adoption of the FMP by the Assistant Secretary. The Team concludes that the revised year 3 milestone for this condition has been met. Evidence has been provided that the harvest strategy has been formally implemented by the Assistant Secretary for Fisheries, LDWF after validation by stakeholders.

Progress on The Client confirmed that the Louisiana Blue Crab Fisheries Management Plan (FMP) had been implemented. It includes (page 36) the specific policy Condition that “Should the fishing mortality or exploitable biomass exceed the overfished or overfishing limits, or exceed the targets for three consecutive years, [2016] as defined in the most current Louisiana blue crab stock assessment, LDWF shall come before the Commission with an updated assessment and a series of management options for the Commission to review and act upon, intended to keep the fishery from becoming overfished, and that management

options for review and action shall include provisions for emergency closures, time based closures, and spatial closures.” The Client confirmed that the most recent stock assessment had been updated to include 2015 data and had concluded that overfishing was occurring and that the stock was overfished. Detailed discussions are currently ongoing between the Blue Crab Task Force (BCTF) and LDWF concerning mechanisms for reducing F with the objective of rebuilding the stock back to target levels. Restricting fishing effort through total seasonal closures of the fishery (with all traps removed from the water) in March,6 when crabs are of poor quality, and/or in October when price per pound is low, are options under consideration, along with: possible limitations on gear; the introduction of biodegradable panels to minimize ghost fishing; and the introduction of larger escape rings. A total seasonal closure of the fishery is the preferred management option, as this would allow time for the cleaning and repairing of traps, while LDWF would undertake a major program to collect lost and abandoned traps that are considered to be a major source of uncontrolled removals of both target and bycatch species. The audit team concluded therefore that the defined harvest strategy has been responsive to the state of the stock and the elements of the harvest strategy work together towards achieving management objectives reflected in the target and limit reference points, and that the 4th year milestone had been met. This led to a rescoring of PI 1.2.1 and a revised score of 85 (Table 8). Status of PI 1.2.1 was rescored at 85 and condition 1 is closed. condition [2016]

At the fourth annual audit the client will present the CAB with evidence to show that explicit algorithm or decision rule which links observed changes in indicators to changes in fishery management measures (note that in the 2014 report this was incorrectly written as annual stock indicators) has been implemented and used in determining the harvest control rules and tools for the following year. Client action Revised Client Action Plan (after 2nd Annual Surveillance Audit) plan At the third annual audit LDWF will provide a formal Blue Crab FMP. The FMP includes management options that will be selected and implemented based upon target and limit reference points reached and identified in an updated stock assessment. Fisheries independent trawl blue crab CPUE may be used as an indicator during certain years (if the assessment is not updated). At the fourth annual audit LDWF will provide evidence that the harvest control rules are in place through the finalization of the Blue Crab FMP, with discussions and approvals of the CTF and LWC and implementation of harvest management control rules. Progress on Minor Non-Conformance. By the second annual surveillance audit provide evidence to the CAB that as per the client action plan the resolution has Condition been agreed, has defined the means of response and a rationale for the response being effective in achieving exploitation levels required under the [2013] HCRs. Progress on The client action plan for condition 2 was the same as for condition 1. Originally the client committed to the definition of an FMP but subsequently this Condition was changed to a Resolution. The initial Resolution did not adequately respond to the identified issue and this led to a new Resolution. [2014] SG80 SIa requires that “well defined harvest control rules are in place that are consistent with the harvest strategy and ensure that the exploitation rate is reduced as limit reference points are approached’. MSC CR v1.1 defines harvest control rules as “A set of well-defined pre-agreed rules or actions used for determining a management action in response to changes in indicators of stock status with respect to reference points”. In our view, the new regulation does not meet this requirement, as there is not a definitive mechanism to reduce the exploitation rate. Rather it meets SG60 SIa i.e. “Generally understood harvest control rules are in place that are consistent with the harvest strategy and which act to reduce the exploitation rate as limit reference points are approached”. In the post certification period, the client has made significant efforts to develop a fishery management strategy including harvest control rules, with the Resolution and reported strong progress in drafting a FMP. Technically we find that the client has not met the condition and remains behind target for two years on a row. In other circumstances, we would consider the requirement as specified in MSC CR v1.1 Para. 27.22.9 and Para 7.4.3 (see above) However, given MSC CR v1.1 Para 27.22.10 (see above) and Para 4.11 that covers the situation where there is a change in CAB (see above) in the context of MSC CR v1.1 c. Para 27.11.3.2 (see above), we consider that while PI 1.2.2 was scored correctly and a condition was required, the initial time scale and the client commitment to the creation of an FMP in one year was neither realistic nor achievable. On that basis we have redefined the condition. The work undertaken to-date means the client is on-target. Progress on The Team and client representatives discussed the applicability of an “explicit algorithm or decision rule” linking changes in stock indicators to changes Condition in management measures in this kind of fishery (as required in the revised Year 3 milestone). Since the suite of technical measures is considered [2015] adequate to maintain the reproductive capacity of the stock, and since TAC or effort control is not used in management, the client, after considering the

revised Year 3 milestone, believes that the development of explicit decision rules such as those used in fisheries managed by TAC is problematic and may not be useful. The Audit Team concurs that the suite of technical conservation measures in place (equivalent to decision rules) represents a substantial contribution to a precautionary approach to conservation of the resource. The client highlighted the commitment in the FMP to present proposals for new management measures to the Fisheries Commission should stock indicators go beyond identified reference levels (see above, Condition 1). Options for management measures to be considered should reference levels be transcended have been outlined in the FMP, such that industry and management authorities have been advised of the potential measures that could be taken if stock indicators reached critical levels. These include emergency closures, time based closures and spatial closures (p 36, FMP), increasing mesh size and increasing minimum legal size (p 46, FMP). The Audit Team also noted that LDWF has recently implemented new management measures to respond to identified conservation and management issues in the fishery. (i) A professionalization program requiring that new entrants undergo training has been put in place, which has had the effect of reducing total effort in the fishery. (ii) Escape rings have been increased in number (from 2 to 3) and size to improve protection of undersize crabs (measure to take effect in 2017). In summary, the Team notes that there has been explicit consideration of management options, as required by the revised Year 3 milestone for this Condition, but that the Client has not presented an explicit algorithm or decision rule linking stock indicators to management actions as required in the milestone. However, the Team concludes that the intent of the Year 3 milestone has been met (i.e. there is evidence that there is a capacity and a commitment to take specified management action should indicators show that the stock has declined below identified thresholds) as:  a process to take management action should stock indicators reach specified levels has been formalized within the FMP;  options for management action under this process have been identified in the FMP, and management authorities and the public are aware of them;  the management system has shown the capacity to respond to conservation and management issues by implementing new management measures The Team considers this process for taking action in the face of decline in stock indicators equivalent to a decision rule as required by the Year 3 milestone. The combination of the strong suite of technical conservation measures in place in the fishery with this action plan represents a suite of harvest control rules which meet the requirements of the PI. The Team concludes that the Y3 milestone for this Condition has been met. The FMP action plan is equivalent to a decision rule linking observed changes in indicators to changes in fishery management measures. This follows an explicit consideration of the various options.

Progress on The Client confirmed that the FMP has been implemented. The FMP includes (page 36) the specific policy that “Should the fishing mortality or Condition exploitable biomass exceed the overfished or overfishing limits, or exceed the targets for three consecutive years, as defined in the most current [2016] Louisiana blue crab stock assessment, LDWF shall come before the Commission with an updated assessment and a series of management options for the Commission to review and act upon, intended to keep the fishery from becoming overfished, and that management options for review and action shall include provisions for emergency closures, time based closures, and spatial closures.” Such actions may also include “increasing mesh size and increasing minimum legal size” (p 46). The audit team confirmed that evidence exists of the capacity and commitment to take specified management action should indicators show that the stock has declined below defined thresholds, with a formal commitment to take management action should stock indicators reach specified levels. The FMP identifies the options for management action ensuring the awareness of the management authorities and the public. Previously, the management system has shown the capacity to respond to conservation and management issues by implementing new

management measures. The audit team confirmed therefore that the FMP action plan is equivalent to a decision rule linking observed changes in indicators to changes in fishery management measures. The Client confirmed that the most recent stock assessment had been updated to include 2015 data. The finding is that overfishing was occurring and that the stock was overfished. Detailed discussions are currently ongoing between the BCTF and LDWF on mechanisms to reduce fishing mortality in order to rebuild the stock back to target levels. Restricting fishing effort through a total seasonal closure of the fishery (with all traps removed from the water) in March (when crabs are of poor quality) and/or in October (when price per pound is low) are measures being considered, along with: possible limitations on gear; the introduction of biodegradable panels to minimize ghost fishing; and the introduction of larger escape rings. Total seasonal closures of the fishery are the preferred management option as these would allow the cleaning and repairing of traps, while LDWF could undertake a major program to remove lost and abandoned traps that are considered to be a major source of uncontrolled removals of both target and bycatch species. Previous experience following Hurricanes Katrina and Rita demonstrated that enforced reductions in fishing effort resulted in significant increases in stock biomass, and that mechanisms for reducing fishing effort are therefore appropriate and effective tools in achieving the exploitation levels required under the HCR. On that basis, the audit team concluded that well defined HCRs are in place that are consistent with the harvest strategy and ensure that the exploitation rate is reduced as LRPs are approached. The 4th year milestone had been met. This led to a rescoring of PI 1.2.1 and a revised score of 80 (Table 9). Whilst there is a well-defined HCR and a re-building strategy is in place based on reducing the level of fishing effort, the audit team stresses that major management action which significantly reduces fishing effort is required to ensure that the stock recovers to target levels and remains at or above the target biomass level. Status of PI 1.2.2 was rescored at 80 and condition 2 is closed. condition [2016]

At the third annual audit the client will present the CAB with evidence that identifies main species and the data needed to undertake a risk based analysis of PI 2.2.1. This will lead to the rescoring of PI2.2.1 and potentially the closing of the condition Client action Revised Client Action Plan (after 2nd Annual Surveillance Audit) plan LDWF’s Marine Fisheries Section is conducting on-going research monitoring trap by-catch; results from this project will be presented at the third annual audit, including the identification of main by-catch species as defined by MSC (5% of the total catch in the fishery, valuable or vulnerable). Analysis of the main species will be done through existing monitoring data. At the fourth annual surveillance audit, LDWF will provide evidence that the fishery does not pose a risk to main by-catch species. Data presented will come through the blue crab by-catch study, the terrapin abundance and distribution research, finfish stock assessments and fishery independent monitoring data. If the condition is closed by the third annual surveillance audit, LDWF will not consider this action item. Progress on Open – On target Condition [2013] Progress on Under the MSC approach, bait fish are considered as retained species (MSC CR v1 Para CB 3.5.5). In the certification, PIs 2.1.1 thru 2.1.3 considered Condition bait species however in the main text of the report they are covered under by-catch species. Possibly, the approach is confused as the CAB differentiated [2014] by-catch by retained and discards, while the MSC approach uses retained (PI 2.1) and by-catch (PI 2.2) and each achieved a score of at least 80; hence a condition was not raised. Thus there is no existing requirement for the client action plan to include any consideration of bait species. As part of this annual surveillance audit, we did review the stock status and information on the main bait species and we did not identify any cause for concern and no need to rescore P 2.1. The purpose of setting a condition is to raise the score of a specific PI to a minimum of 80 within a defined period of time. For PI 2.2.1 SG 80 considers “main” species (as defined above). It is at SG 100 that all by-catch species are taken into consideration. On that basis, we consider that the second sentence of the existing condition (“By the third annual surveillance provide evidence to the CB that all by- catch species, including terrapins, are highly likely to be within biologically based limits”) should be limited to main by-catch species. Further, we do not consider it realistic or achievable that there is sufficient time within a 3-year time frame to assess whether or not main by catch species including terrapins are highly likely to be within biologically based limits. In addition, the first sentence in the condition relates to information and should be covered under PI 2.2.3. On that basis, and bearing in mind the arguments used to justify a change in the approach to Conditions 1 and 2, we have redefined the condition. In the meantime we consider that the work undertaken to-date means the client is on-target. Progress on The Client provided updated results (to May 2015) of the on-going by-catch survey, which started in 2012 and is scheduled to complete in June 2015. Condition As in the 2014 report, hardhead (“sea catfish”) was the most abundant species in the by-catch, with 976 individuals. Total weight of this species [2015] was estimated from length data collected on the survey and an existing length-weight relationship, at 659 lbs. The next most important species in estimated weight was Atlantic croaker at 45 lbs. (131 individuals). All other species were at much lower weights and numbers.

Louisiana Blue Crab

Total survey catch of commercial-sized blue crabs was 5,531 lbs. Accordingly, hardhead catfish represented approximately 10% by weight of the total catch (5531+659+45 = 6235 lbs.), while Atlantic croaker represented 0.7%. On the basis of weight, hardhead catfish is the only “main” by-catch species. Although application of a simple catch weight ratio (hardhead catfish: blue crab) to total blue crab catch (ca. 40m lbs. / yr.) might not provide an accurate estimate of total hardhead catfish catch in the fishery, the total amount caught could potentially be of the order of 4 - 5 million lbs./yr. However, hardhead catfish is a very widely distributed, abundant species (GCRL 2015) and is highly productive (age at maturity less than 2 yr., life span 5-8 yr.) (GCRL 2015). Fecundity is low (20-65 eggs) but this species is a mouth brooder of eggs and young, which greatly increases survival of young compared to high-fecundity broadcast spawners. The species has no commercial value or culinary interest, so all individuals caught would be discarded, and discard survival is likely quite high (of the order of 90% J. Marx, pers. comm.). The updated by-catch survey results showed a total catch of 12 diamondback terrapin (DBT). As noted in the Year 2 audit report, due to vulnerability it would be precautionary to consider this species as a “main” by-catch species. To be classified as an MSC main species, a by catch species must comprise more than 5% of the catch by weight, be considered as valuable or be vulnerable. As the biological status of diamond back terrapin taken in the fishery is uncertain, using a precautionary approach in the context of the known status of the species in other US waters, we consider that it may be vulnerable. It may be the case that evidence becomes available to consider that the species is not vulnerable. It is confirmed that DBT must be considered a main species. While the client has spent considerable resources (about $500,000) to clarify the situation as yet the research has not led to any definitive conclusions. There is continued uncertainty on DBT’s status and the impact on it by the blue crab fishery. In addition, only limited information is available on hardhead catfish which is a main bycatch species. Review of MSC CR v1.3 Table AC2 indicates that if the impact of the fishery in assessment on the P2 species cannot be determined quantitatively the risk based framework should be used to generate an MSC score. This being the case, we propose to carry out the required risk based analysis at the fourth annual surveillance audit / site visit for the reassessment. This will follow MSC CR v1.3 Annex CC and involve stakeholders to inform the process. In preparation for the RBF, we recommend that the client compile information on the status of the hard head cat fish and diamondback terrapin population, the impact of the fishery on the population and the effectiveness of related management options. Progress on We reviewed the status of the bait species. As found by the 2014 audit, there is no concern for their sustainability and the potential impact of the blue Condition crab fishery on them. [2016] The main point for analysis in this fourth audit was confirmation of the main bycatch species and to review the previously allocated score and associated rationale. The client provided us with up-dated by catch data. A sample of 354 sets and 16,480 traps recorded a blue crab catch of 5,728 lbs. with a total by catch of 1,732 lbs. A total of 37 by catch species were identified. The most often caught was hardhead catfish ( felis) with the total 637 lbs. (1,021 fish) representing 8.54 % of the total catch. While 98.6 % of the sea catfish was released alive, there is no information on post release mortality. Given that the species is of no commercial value and most of the catch is released live, it may be possible to argue that while it comprises more than 5 % of the catch, it is not a main by catch species. This issue should be revisited if the fishery enters the recertification process. On the basis of the foregoing and previous audits, it is pertinent to question whether or not DBT should be considered a main by catch species.

Due to the lack of information at the time, the original scoring for PI 2.2.1 presented limited rationale for considering DBT as a main bycatch species. There was recognised limited cross over of the blue crab fishing area with the main habitat of the DBT. The main issue identified was the potential for ghost fishing in discarded or lost traps, with a claim that “tens to hundreds of thousands” of traps per year are potentially ghost fishing. There is now better information. DBT was ranked 13th in the number of individuals taken in the fishery, with 12 caught with a total weight of 18 lbs. to 24 lbs (0.24 % - 0.32 % of the total catch weight). 41.7 % was released alive. There is no information on post release mortality. In the clear-up operation in 2015 (see below) no DBT were found in the removed traps that were sampled for by catch. In the original rationale, no reference was made to the existence of a commercial fishery for DBT in Louisiana. It is legal to catch DBT all year except for 2 months from April 15. It is illegal to use any type of trap. There is a minimum carapace length of 6 inches. In its most recent publication, the Louisiana Wildlife Federation noted “LWF requests the Louisiana Department of Wildlife and Fisheries to monitor and report the commercial harvest of Diamondback terrapins in Louisiana and to assess the impact of increasing exports of the turtle on the sustainability of its wild population. LWF supports additional rules or restrictions on commercial harvest of Diamondback terrapins in Louisiana as necessary to maintain a sustainable wild population. There is a significantly increasing trend of Diamondback terrapin exports from 833 in 2003, to 4,401 in 2010, 3,734 in 2011, 4,003 in 2012, 2,596 in 2013, and 16,226 in 2014”. In addition, DBT is used for direct human consumption. While it may be argued that DBT is not a main species, it is selected to maintain the approach of the original assessment. In the event of the fishery going to recertification, this decision may be reviewed. Review of MSC CR v1.3 Table AC2 indicates that if the impact of the fishery in assessment on the P2 species cannot be determined quantitatively the risk based framework should be used to generate an MSC score. In difference to the original assessment that presented an unclear rational to score the fishery at 70 using the default assessment tree, we decided that the RBF must be used to score PI 2.2.1. Status of On the basis of the evidence available, PI 2.2.1 was rescored using RBF. The allocated SICA score was 2 which is equivalent to an MSC score of 80. condition [2016] Accordingly, it is concluded that the fishery now meets that part of the MSC standard contained in PI 2.2.1 and CONDITION 3 IS CLOSED.

By the fourth annual audit, there is evidence that there is a partial strategy in place, if necessary, that is expected to maintain main by-catch species at levels which are highly likely to be within biologically based limits or to ensure that the fishery does not hinder their recovery; there is some objective basis for confidence that the partial strategy will work, based on some information directly about the fishery and/or the species involved; and there is some evidence that the partial strategy is being implemented successfully. Milestones Revised Milestones (after 2nd Annual Surveillance Audit) At the third annual audit, the client will present the CAB with evidence that confirms the efficiency of the lost trap removal programme. At the third annual audit, the client will present the CAB with evidence that options for a partial strategy, if necessary, have been identified and discussed. At the fourth annual audit, the client will present the CAB with evidence that the partial strategy, if necessary, has been implemented. Client action Revised Client Action Plan (after 2nd Annual Surveillance Audit) plan The Louisiana derelict crab trap removal program was initiated in 2004; funds are generated through fees dedicated from sales of recreational and commercial crab trap gear license fees. Plans have been initiated to continue the program in 2015. At the third annual surveillance audit, LDWF will present updated information concerning progress with the derelict crab trap removal program. Diamondback terrapins are listed as a main by-catch species because of their inherent vulnerability. Results from the on-going LDWF blue crab by- catch survey along with the terrapin abundance and distribution research will indicate if the blue crab fishery is hindering terrapin “recovery”. Current regulations and options for future management will be presented at the third annual audit. At the fourth surveillance annual audit, LDWF will present information concerning management actions initiated for main by-catch species, if needed. Progress on Open - On target Condition [2013] Progress on To provide the basis for effective future surveillance audits, we consider that the condition and associated milestones need to be reworded. In the Condition meantime, we consider that the work undertaken to-date means the client is on-target. [2014] Progress on The client provided an update of the annual report on the derelict crab trap removal program, which has been under way since 2004. In February 2015, Condition 422 derelict traps were removed in the Sabine Lake area, bringing the total for the program to 24,645 traps removed (LDWF 2015dc). The 2015 [2015] removals were lower than in most previous years. No updated information on by-catch in the derelict traps was provided, however the Team noted that a publication on by-catch in derelict traps removed in the program in 2012-2013 had recently appeared (Anderson & Alford 2014). The trap removal program has concentrated on the inter-tidal zone, in part because this is the probable area of concentration of terrapin by-catch. The trap removal program will continue in future. A proposal to NOAA for a grant to apply new methods to derelict trap removal under the NOAA marine debris removal program has been accepted. A similar program in North Carolina was successful in removing several thousand crab traps. Total funding will be $276,000 with $135,000 from NOAA.

The one-year project in Barataria/Terrebonne/Pontchartrain areas will assess the use of side scan sonar to locate derelict traps, and consider the contracting of unemployed crab fishermen to remove traps. With respect to a potential partial strategy to manage terrapin by-catch, the new FMP includes a number of options including: use of terrapin excluder devices in certain areas; use of biodegradable panels or hardware; and designation of areas prohibited for use of crab traps in habitats important for by-catch species (pp. 45). Options for managing ghost fishing and derelict traps (p. 47) include: bio-degradable panels; requiring fishermen to tend traps within a specified period of time; the removal of inactive traps; warning or penalizing fishermen whose registration numbers are found on derelict traps, including fishermen in derelict trap clean-ups; and using side scan sonar to locate derelict traps (the latter two options will be explored under the NOAA grant). LDWF staff reported that the potential to use bio-degradable panels to reduce the impact of ghost fishing panels has been considered, but currently fishers consider the cost ($25-$30 per trap) to be too high. Trap theft (a significant issue over many years) may have contributed to some of the higher estimates of trap loss given in published reports. The Team notes that the MSC Certification Requirements (v 1.3 CB 3.3.1, 3.3.2) indicate that the “if necessary” wording in relation to a partial strategy is only relevant if the fishery has no impact on the component under consideration i.e. a partial strategy would be required to manage main by-catch species unless the fishery had no impact on these. As the fishery is thought to impact the diamondback terrapin, a partial strategy would be necessary for the fishery to meet SG80 SIa. MSC requirements for a “partial strategy” are outlined in the Guidance to Certification Requirements, v 1.3, section GCB 3.3, page GC 83. In addition to new measures, measures already in place which could reduce the impact of the fishery may be part of the partial strategy. The need for a partial strategy will be clarified following the RBA proposed for the 4th annual surveillance report / recertification site visit. The Team concludes that the revised Year 3 milestones for this Condition have been attained. The Client has presented evidence that confirms the efficiency of the lost trap removal programme (an update on trap removals, the accepted NOAA grant application for further work), and evidence that options for a partial strategy to manage by-catch of main species, if necessary, have been identified and discussed (in the FMP). Accordingly, progress is on track to meet this Condition in Year 4 as required. Progress on The RBA indicates that there is some potential for the blue crab fishery to impact DBT which has been considered as a main by catch species. Condition Accordingly, to meet PI 2.2.2 SG80 a partial strategy is required. In difference, there is no indication that the blue crab fishery may impact the hardhead [2016] catfish; thus a partial strategy for this species is not required The client presented us with the following summary of NOAA funded project. “LDWF was awarded a contract from the NOAA Marine Debris Removal Program in July 2015. The goal of the contract is to remove 20 metric tons of debris in the form of ghost traps. Two components of the program are: 1) holding two volunteer derelict crab trap removal events and 2) conducting side-scan sonar of selected areas and removing submerged derelict crab traps. Two large scale volunteer events for derelict trap removal were held. Lake Pontchartrain Basin Foundation (LPBF) was contracted to coordinate the volunteer clean up event in the Lake Pontchartrain basin and hold the art competition. The Barataria-Terrebonne National Program (BTNEP) was contracted to coordinate the volunteer clean up event in the Barataria basin and hold volunteer events to retrofit crab traps with biodegradable panels. During both volunteer cleanup events, LDWF personnel collected bycatch data on 12% of the 1428 traps collected. There were no Diamondback Terrapins found in those traps. Cleanup continued during the closure period and the total number of derelict crab traps that were retrieved during both

closures was 2,580. Side scanning of selected grids in both Lake Catherine and the Pen were completed. Trap retrieval has begun with the weather not being very agreeable to this point. In the Pen, grids 6 and 7 were cleaned and a total of 42 traps were retrieved out of a total of 119 targets. In Lake Catherine, grid 65 was cleaned with a total of 9 traps retrieved out of a total of 45 targets. The decision to scan grids and come retrieve traps at a later date was incorrect. This is what is causing the high amount of false targets. There have been no Diamondback Terrapins found in the 51 traps collected from the side-scan project”. While not implemented as yet, if there is a closed season for blue crab fishing in 2017, with all “active” traps removed from the water, LDWF will have the opportunity to increase efforts to remove lost and discarded traps.

Status of On the basis of the evidence available, PI 2.2.2 was rescored to 80. Accordingly, it is concluded that the fishery now meets that part of the MSC condition [2016] standard contained in PI 2.2.2 and CONDITION 4 IS CLOSED.

recreational fishing activities. Results from the 2014 survey of derelict traps will be analysed and used to continue collecting information during derelict trap removals. At the fourth annual surveillance audit, LDWF will present all updated data on by-catch in the commercial blue crab trap fishery. Progress on Open - On target Condition [2013] Progress on Information on by-catch and species’ abundance and distribution has been substantially improved through survey programs that are expected to Condition continue through 2016. The data derived will support an assessment of the impact of the fishery and development of a partial strategy to ensure that [2014] impact does not prejudice biological status, if necessary. We recommend that LDWF estimate weight of target species and by-catch species catch such relative weights can be determined and compared to the MSC guideline of 5% of target species catch weight for “main” by-catch species. We recommend that an estimate of total by-catch of this species in the fishery be prepared (recognising that significant uncertainties and assumptions will underlie such an estimate) and that this be compared with information on abundance of the species in the wild (from the ongoing LDWF study of distribution and abundance) such as to assess the impact of the fishery on the population. We conclude that the impact of ghost fishing on by-catch species appears to be relatively limited although this needs to be further analysed. Annual and cumulative removals of lost traps over 10 years appear relatively small relative to estimates of total potential traps lost but represent a substantial effort to address the issue. The impact of ghost fishing should continue to be monitored on future surveillance audits. We recommend that further information be collected on catch in derelict gear, and that the available information be analysed to estimate the impact of derelict gear on target and by-catch species. As argued for Conditions 1 thru 4, we consider given the need to prepare a research programme, source funding, implement the research and collect and analyse data, the time allowed to meet the condition was not realistic. On that basis and to link with Conditions 3 & 4, we have revised the condition with a new milestone. Progress on The Client provided updated results (to May 2015) of the on-going by-catch survey, which started in 2012 and is scheduled to complete in June 2015. Condition As in the 2014 report, hardhead catfish (“sea catfish”) was the most abundant species in the by-catch, with 976 individuals. Total weight of this species [2015] was estimated from length data collected on the survey and an existing length-weight relationship, at 659 lbs. The next most important species in estimated weight was Atlantic croaker at 45 lbs. (131 individuals). All other species were at much lower weights and numbers. Total survey catch of commercial-sized blue crabs was 5,531 lbs. Accordingly, hardhead catfish represented approximately 10% by weight of the total catch (5531+659+45 = 6235 lbs.), while Atlantic croaker represented 0.7%. On the basis of weight, hardhead catfish is the only “main” by-catch species. Although application of a simple catch weight ratio (hardhead catfish: blue crab) to total blue crab catch (ca. 40m lbs. / yr.) might not provide an accurate estimate of total hardhead catfish catch in the fishery, the total amount caught could potentially be of the order of 4 - 5 million lbs./yr. However, hardhead catfish is a very widely distributed, abundant species (GCRL 2015) and is highly productive (age at maturity less than 2 yr., life span 5-8 yr.) (GCRL 2015). Fecundity is low (20-65 eggs) but this species is a mouth brooder of eggs and young, which greatly increases survival of young compared to

high-fecundity broadcast spawners. The species has no commercial value or culinary interest, so all individuals caught would be discarded, and discard survival is likely quite high (of the order of 90% J. Marx, pers. comm.). The updated by-catch survey results showed a total catch of 12 diamondback terrapin. As noted in the Year 2 audit report, due to vulnerability it would be precautionary to consider this species as a “main” by-catch species An updated version of the terrapin study funded by LWDF was provided to the audit team (LDWF 2015dt). This did not appear to contain substantial new information compared to the version reviewed on the Year 2 audit. Diamondback terrapins were found to be widely distributed in Louisiana coastal waters, but population assessments have not been carried out, and there has been no assessment, however preliminary, of the impact of the blue crab fishery on populations. Research on terrapin populations and the impacts of blue crab fisheries in other areas has suggested that by-catch in crab fisheries, along with a range of other threats (nest depredation, habitat degradation, road kills) could be linked to declines in terrapin abundance (see reviews by e.g. Roosenburg 2004, Hart & Crowder 2011). However, the species is difficult to survey, and there are many uncertainties about quantitative impacts of the various threats. Available work suggests that traps set in intertidal areas near shore have more impact than those in deeper areas (e.g. Hart & Crowder 2011, Gandy & Turner 2014), as terrapins are not usually found in deeper waters, and that derelict traps appear to be particularly problematical (perhaps in part because these are often concentrated in intertidal waters) (e.g. Anderson & Alford 2014). Mitigation measures identified in literature include prohibiting crab fishing within a specified distance from shore, prohibiting fishing in specified seasons, and use of by-catch reduction devices (Hart & Crowder 2011). These options were identified in the Louisiana Blue Crab FMP (LDWF 2014). Many studies confirm that sampling and surveying are particularly challenging for this species. Intensive small-scale surveys may be required to estimate population sizes, and extensive larger-scale surveys may be adequate to map distributions but not to estimate population sizes (e.g. Gandy & Turner 2014). Although new information on the derelict trap removal program was presented (see Condition 4), new information on by-catch in derelict traps and its potential impact on populations of by-catch species was not available. The Team concludes that the year 3 milestone has been met by client - quantitative information on the level of by-catch and the identification of the main by-catch species. Hardhead catfish is the only “main” by-catch species on the basis of weight. Diamondback terrapin is a “main” by-catch species on the basis of vulnerability. The recommendation put forward in the Year 2 audit to estimate total by-catch of diamondback terrapin in the fishery, and to compare this with abundance information from the LDWF survey, such as to estimate impact of the fishery, has not been followed-up by the client. Such an assessment would be needed to meet SIb of the SG 80 for PI 2.2.3 (information is sufficient to estimate outcome status with respect to biologically based limits) and possibly SIc (Information is adequate to support a partial strategy to manage main by-catch species).

Progress on Not recorded in the First Annual Surveillance Report. Condition [2013] Progress on We have some concern that Condition 6 duplicates Condition 5. However, as we conclude that progress is on track to meet the Condition within the Condition timeline specified, we will review this issue when the PI is rescored. [2014] Progress on The Team gave further consideration to whether this Condition duplicates Condition 5 (PI 2.2.3, information on by-catch species) with respect to DBT. Condition Condition 6 was established because of uncertainty about the impact of the fishery on the ecosystem, through its potential to reduce populations of [2015] DBT. However, despite a large literature of studies on the biology of DBT (reviews by, for example, Butler et al 2006, Hart & Lee 2007, and more recently Coleman 2013), we did not find any evidence that any reduction in DBT abundance from by-catch in the fishery would have significant ecosystem impacts with serious or irreversible harm to the ecosystem, DBT is ecologically unique in being the only turtle species living in brackish-water habitats, and it certainly is an important component of food webs in these habitats. However, if removal or reduction in abundance of this species was to have a significant ecosystem impact, we would expect there to be evidence to show that predation by the species (or some other ecological function it exerts) plays a structuring role, as a keystone predator for example. Although we have seen speculation that predation of DBT on Littorina molluscs could reduce the snails’ grazing on Spartina beds, and thus contribute to ecosystem health (Coleman 2011), we have seen no evidence to support such a role. There is evidence that removing Littorina from Spartina beds results in increased Spartina biomass, (Gustafson et al 2006), but we are not aware of evidence of a role of DBT in controlling Littorina

abundance. In one area (Kiawah Island, SC) the DBT diet was 76-79% Littorina, but in others a much wider range of prey, including snails, clams, mussels, crabs, insects, fish, worms and vegetation has been reported (Butler et al 2006). Substantial declines in abundance of DBT have been reported in a number of areas, but we have not found evidence that these have been associated with ecosystem changes, in particular changes which could cause serious or irreversible harm. In the absence of evidence for a structuring role of DBT in ecosystems, or for serious or irreversible harm occurring in ecosystems as a result of documented DBT population declines, we conclude that it would be more appropriate to consider impact of DBT by-catch under by-catch and not ecosystem. There has been progress in providing information on by-catch of DBT in the fishery (see Condition 5); as in Year 2 we conclude that progress is on track to meet this Condition. Review of MSC CR v1.3 Table AC2 indicates that if the impact of the fishery in assessment on the ecosystem cannot be determined quantitatively the risk based framework should be used to generate an MSC score. This being the case, we propose to carry out a risk based analysis for PI 2.5.1 to estimate the impact on the ecosystem of removal of DBT by the fishery at the fourth annual surveillance audit / site visit for the reassessment. This will follow MSC CR v1.3 Annex CC and involve stakeholders to inform the process. In preparation for the RBF, we recommend that the client compile information on the status of the ecosystem and the impact of the fishery on the various elements. This will allow consideration of the score for 2.5.3. Progress on We reviewed our findings in 2015 in the context of our concern that the scoring of the fishery based on the lack of information on DBT constituted Condition double jeopardy as these issues were taken into account under Component 2.2. [2016] Given that research completed by the client over the past 4 years provides an estimate of total mortality in the fishery, we consider that the original experts were mistaken in finding that the fishery only met SIa (Information is adequate to broadly understand the key elements of the ecosystem) and SIb (Main impacts of the fishery on these key ecosystem elements can be inferred from existing information and some have been investigated in detail) for PI 2.5.3 were met. It is unclear as to why the experts concluded that SIc SG80 (The main functions of the Components (i.e., target, Bycatch, Retained and ETP species and Habitats) in the ecosystem are known) was not met. The decision to not award the fishery SG80 SId was predicated on the lack of information on DBT. This issue has now been resolved. As with SIc SG80 it is unclear why the experts concluded that SG80 SIe (Sufficient data continue to be collected to detect any increase in risk level (e.g., due to changes in the outcome indicator scores or the operation of the fishery or the effectiveness of the measures) was not met. Notwithstanding the concerns expressed about the original scoring, with the by catch data available it appears clear that the client has complied with the condition (By the third surveillance audit, provide information on the impact of the fishery on ecosystem components like the terrapins taken as by catch in the Blue Crab fishery to allow the main consequences for the ecosystem to be inferred).

6 Summary 1. We found that the substantial progress made by the client enabled us to rescore the relevant PIs (1.2.1, 1.2.2, 2.2.1, 2.2.2, 2.2.3 and 2.5.3). Each of these PIs achieved a score of 80 or above, allowing us to close the existing conditions to certification. 2. However, the most recent stock status up-date (LDWF 2016) concluded that the stock moved below SSBLIMIT in 2015 although the previous year it was at SSBTARGET. In 2014, F was close to its LRP. The 2015 catch-survey model does not provide a current estimate of F. On that basis, we determined to re-score PI 1.1.1. As the most recent stock assessment estimated that SSB was lower than SSBtarget in two of the last four years, we concluded that the stock was not at or fluctuating around its TRP and PI 1.1.1 SG80 SIb was not met. In relation to PI 1.1.1 SIa, on reviewing the evidence and after consideration of: (i) the biology of the target species; (ii) the limited difference between the TRP and LRP; and (iii) the previous recovery of the fishery from similar levels, we concluded that it is likely that the fishery is above the point where recruitment would be impaired and met SG60a. The score of 60 for PI 1.1.1, led to a new condition (7) being on PI 1.1.1. It meant also that we had to score PI 1.1.3. The score for PI 1.1.3 is 80. 3. As this is the final surveillance audit for the current period of certification and the indications are that the fishery will not move to recertification, this condition will not impact the MSC status of the fishery. Should it be the case that the fishery does seek recertification, it is likely that the new condition would apply to allow the fishery, all things being equal, to be certified until Year 4, by which time it is expected that the stock would be fluctuating around the TRP. 4. Whilst there is a well-defined harvest control rule and a re-building strategy is in place based on reducing the level of fishing effort, the audit team stresses that major management action which significantly reduces fishing effort is required to ensure that the stock recovers to target levels and remains at or above the target biomass level. 5. To facilitate the management process, it is recommended that the client considers the definition of an additional biological reference point, with a trigger reference point between the current upper (target) and lower (limit) reference points. It is further recommended that the client considers options to widen the number of stock indicators beyond the current two which are based on exploitable biomass and fishing mortality. 6. Table 5 shows the revised Principle and PI scores.

7 Conclusion The Louisiana Blue Crab Fishery is certified according to the MSC standard for sustainable fisheries until 8th March, 2017. One condition to the certification is open.

Y N N MSC CR v1.3 Guidance (GCB2.2) notes that “for some short-lived stocks the actual point at which there is an appreciable risk that recruitment is impaired may be lower than (the default limit reference points which are generally consistent with being above the point at which there is an appreciable risk that recruitment is impaired)”.

The blue crab is a short-lived, highly productive species. Its SSBlimit was set to ensure that the stock does not fall below the three lowest levels observed (1968-2009) where the stock demonstrated sustainability (i.e. no observed declines in recruitment over a wide-range of exploitable biomasses). The 2015 stock assessment shows that, from 2012, the SSB estimate fluctuated between SSBtarget and SSBlimit. While the 2015 estimate was the lowest level recorded

in the 4-year series, the stock demonstrably recovered from SSB levels around

SSBlimit in the 1990s and 2000s and so SSBlimit can be considered to be precautionary and set above the point at which recruitment would be impaired. For this species, in preference to a LRP, the recruitment risk point is used to measure stock status. We note that there is no observed relationship between exploitable

Justification biomass and future recruitment. Although recruitment levels over the last few years are lower than observed at times in the historical time series, recruitment has not declined significantly since the SSB dropped below the TRP in 2012, and in fact showed a slight increase in 2015 (Figure 4 above). Current recruitment levels are also higher than observed recruitment in the mid-1970s, after which the stock made a strong recovery. In view of: the demonstrable recovery of the stock from similar previous stock levels; the small difference between the SSBtarget and SSBlimit reference points; and the short- lived nature of the target species, we conclude that it is likely that the stock is currently above the point where recruitment would be impaired and thus the SG60 is met. As the 2015 SSB estimate is lower than the SSBlimit, we take a precautionary approach and concluded that SIa SG80 is not met. The stock is at or There is a high degree of

Met? N N The latest stock assessment shows that for the last year when estimates of both F and SSB are available (2014), SSB was at or just below SSBtarget, while F was 0.97 x Flimit. On that basis, it can be concluded that in 2014 the stock was at SSBtarget. This compares the 2013 model result that gave SSB at SSBlimit. i.e. overfished. This was after a period when SSB had been at or above SSBtarget in the previous 8 years, and F was below Ftarget.

In 2015, the SSB estimate is below SSBlimit, but the catch-survey model did not provide a 2015 estimate for F. Based on SSB and F estimates in 2014 and the SSB

estimate in 2015, there is overfishing and the stock is overfished. Although there is Justification only a small difference between the TRP and LRP such that the stock has been observed to move between the two in a single year, it cannot be concluded that the stock is at or fluctuating around its target reference point and the SG80 is not met.

Met? Y N Strategies for re-building depleted stocks are implicit within the FMP, the goal of which is to ensure long term conservation and sustainable use of the blue crab resource including preventing overfishing and ensuring that crabs are able to successfully reproduce and maintain their population, and achieve a level of fishing capacity that provides for a sustainable harvest. In addition, in 2014 the LWFC established a policy based on overfishing and overfished limits and targets: “Should the fishing mortality or exploitable biomass exceed the overfished or overfishing limits, or exceed the targets for three

consecutive years, as defined in the most current Louisiana blue crab stock assessment, LDWF shall come before the Commission with an updated assessment and a series of management options for the Commission to review and act upon, intended to keep the fishery from becoming overfished, and that management options for review and action shall include provisions for emergency closures, time

based closures, and spatial closures.” Justification In view of this policy, LDWF is currently investigating a range of management options for ensuring that F is reduced and the SSB is increased. LDWF actions can be considered as a rebuilding strategy for the stock. Previous experience following Hurricanes Katrina and Rita demonstrated that enforced reductions in F resulted in significant increases in SSB, and thus the re-building strategies have a reasonable expectation of success.

It can be concluded that the harvest strategy is responsive to the state of the stock and is designed to achieve stock management objectives reflected in the TRP and LRP. SG60/80/100 SIa is met.

Y Y The formally implemented FMP includes (page 36) the specific policy that “Should the fishing mortality or exploitable biomass exceed the overfished or overfishing limits, or exceed the targets for three consecutive years, as defined in the most current Louisiana blue crab stock assessment, LDWF shall come before the Commission with an updated assessment and a series of management options for the Commission to review and act upon, intended to keep the fishery from becoming overfished, and that management options for review and action shall include provisions for emergency closures, time based closures, and spatial closures.” Such actions may also include “increasing mesh size and increasing minimum legal size” (p 46, FMP). We consider that the FMP action plan is equivalent to a decision rule linking observed changes in indicators to changes in fishery management measures.

SG60 SIa is met.

The Client confirmed that the most recent stock assessment had been updated to include 2015 data and had concluded that overfishing was occurring and that the stock was overfished. Detailed discussions are currently ongoing between the BCTF and LDWF concerning mechanisms for reducing F and rebuild the stock back to

Justification target levels. Restricting F through total seasonal closures of the fishery (with all traps removed from the water) in March, when crabs are of poor quality and/or in October when price per pound is low, are measures being considered by LDWC, along with possible limitations on gear, the introduction of biodegradable panels to minimize ghost fishing, and the introduction of larger escape rings. Total seasonal closures of the fishery are the preferred management option as they would allow the cleaning and repairing of traps, while LDWF can undertake a major program of clearance of lost and abandoned traps, which are considered to be a major source of uncontrolled mortality of both target and bycatch species. We conclude that the well-defined HCRs in place are consistent with the harvest strategy and ensure that the exploitation rate is reduced as LRPs are approached. SG80 SIa is met

Rationale for selecting worst Recent research has indicated 37 by catch species in the blue crab trap fishery. One of these species (hard head catfish) is categorized as main due to it plausible case scenario forming about 8.5 % of the total catch in the sample. In the original assessment DBT was considered main due to its perceived vulnerability, especially to ghost fishing by lost gear. As hard head catfish is not a commercial species and a very high part of the catch is released live, it was concluded that it was not vulnerable. On that basis, and to maintain coherence with the original assessment, DBT was considered the most vulnerable. Note that trap fishing is prohibited in the commercial DBT fishery. DBT can be taken in both active traps and discarded traps. Survivability in the former was found to be 41.7 %. The survival potential depends on the period of time between the DBT entering the trap and the trap being lifted. By their nature, DBT entering discarded / lost gear have limited potential to survive. However, DBT are likely to only enter discarded traps that contain food, and only in those areas of the DBT habitat (marshy ground outside the main blue crab fishing area) where discarded traps may be found. The lack of escape rings prevents DBT from exiting the trap. The results of recent research indicate that about 0.28 % of the total catch weight consisted of DBT. If the total catch in traps targeting blue crabs was about 57 million pounds, there is a potential DBT catch of 136,800 lbs., or about 78,000 animals with direct mortality of about 45,000. Potentially, this exaggerates the vulnerability of DBT in the fishery, as the majority of the trap sets are not in areas forming the preferred habitat of DBT. No dead DBT were found in the recovered traps that were sampled for by catch. On that basis, we determined that DBT interactions with active gear was the worst possible case scenario, with the main sub component being population size. The potential for interactions of DBT with active fishing and ghost fishing will reduce with the introduction of escape rings and the continuing clear up of derelict gear.

Rationale for Spatial scale of activity The preferred habitat of DBT is marshy areas while traps are usually set on soft or muddy ground up to 3 miles off shore. It would seem reasonable to assume that the overlap would be no more than 30 %, and may be much lower. This is a SICA score of 3. Rationale for Temporal scale of The blue crab fishery operates throughout the year. This is a SICA score of 6. activity Rationale for Intensity of activity Given the limited blue crab fishery in the DBT preferred habitat, it is concluded that a SICA score of 3 is appropriate i.e. moderate detection of activity at broader spatial scale, or obvious but local detection. Rationale for choosing most Given the lack of understanding of DBT is Louisiana waters, it is considered that population size would be relevant sub component affected by the catch vulnerable sub-component of the blue crab fishery. Rationale for Consequence score A review if the literature indicates that in the USA, DBT faces a large number of threats including direct human impacts, climate change, pollution, commercial fishing and by catch. As there is a limit in the overlap between the two elements, on that basis, it must be concluded that the blue crab fishery contributes to potential vulnerability and there is possible detectable change in size/growth rate but minimal impact on population size and none on dynamics.

recovery and rebuilding. Previous annual surveillance reports have indicated a number of measures that have been taken to ensure the fishery does not hinder their recovery and rebuilding of DBT. These relate to the active fishery and ghost fishing. The fishery meets SG60 SIa for DBT. Cumulatively, the measures that form a partial strategy include: reducing the

Justification number of fishers to exclude non-professional fishers and limit effort and the removal of derelict traps. In the 2015 trap removal program, 1,428 traps were collected bringing the total over the various years of the programme to about 26,000. Due to the limited overlap of the fishery with DBT, such a partial strategy is considered sufficient to meet SG80. As SG100 relates to all by catch species, the fishery does not meet SG100.
