Open and welcome The chair welcomed the participants and opened the meeting at 8:45, 15.12.2011. 2. Adoption of the agenda Agenda was adopted without changes. 3. Project work plan – short report on implemented actions so far 3.1 Sampling of adult salmon (coastal and estuarine) and juveniles (rivers): status and numbers Coastal, fjord and estuary - sampling of adults in 2011 Russian coastal and estuarine sampling 2011 Sergey Prusov reported on the actions implemented in Russia. Adult fish sampling was conducted from commercial catches in the Terskiy Bereg of Murmansk oblast and in the Zimniy Bereg of Archangelsk oblast. Samples were also collected from fish taken in the research fishery on the Rybachiy Peninsula (early July). Estuarine areas in 2011: adult fish sampling was conducted from commercial catches in the Pechora River and Severnaya Dvina River (August– September). Samples were also collected from fish taken in the research fishery in the Varzuga River. Number of samples: Terskiy Bereg – 500, Zimniy Bereg – 60, River estuaries – 240, Rybachiy – 50. In total: 850 samples. The commercial fishery starts in the White Sea for a couple of weeks period in June, and they resume fishing in late August in Kola Peninsula area of the White Sea. In Archangelsk region fishing at the Zimniy Bereg and Letnjj Bereg is conducted. There is no fishery along the Karelian coast, just subsistent fisheries: none samples from here. Quota regulations in Kola Peninsula area: up to 20 tonnes total for all stations in use today. Five (5) fishing entities (“users”) have quota for coastal salmon fishing on the Kola Peninsula today. In Archangelsk region the quota is 15 tonnes in total, this is a newer system in this region with up to 200 users, distributed on the existing fishing stations. Plan for 2012 – coastal and estuarine sampling Russia Plan for the year 2012 is to continue salmon coastal/ estuarine sampling in June-July in Letnij Bereg (summer coast) of Archangelsk oblast and Rybachiy Peninsula areas, July in Teriberka area (northeast on the Kola Peninsula - East of Kola river). Discussion and questions: Up to date the amount of Russian adult scale samples collected from coastal and estuary fishery is approximately 1100 (2008, 2010 and 2011), the plan is to analyse up to 2200 adult Russian salmon scale samples. Is there other historical adult scale material available for the project, and if yes in what amounts? Norwegian coastal sampling 2011 Martin Svenning reported from the results from the coastal sampling in Norway. Sampling localities: number of localities in Nordland: 3, in Troms: 6 and in Finnmark: 29. The sampling of adult salmon was conducted by professional sea fishermen using commercial fishing gear, i.e. hook nets and/or bag nets. The fishermen involved were given a special permission (applied from DN) when fishing outside the ordinary fishing season (~May and 5th August- 8th September) or during the ordinary season if fishing was conducted with a method or gear being otherwise prohibited. The special fishing permission was connected to the person fishing and his legal fishing site. A few fishermen had access to two localities when fishing with the special permission in May month, while most of them are allowed to use only one site. During the ordinary fishing season fishermen are allowed to use 1-3 sites. The average catch in Nordland: 95 fish/ fisherman, average catch in Troms: 393 fish/ fisherman (+ 47 additional samples from Malangen) and in Finnmark: 189 fish/ fisherman. 1 Eero Niemelä reported the numbers Norwegian adult scale material and its further process. Material from sea collected in 2011: material included 7253 wild salmon; 1050 escaped salmon, 2 kelts, 33 trout, 4 Pacific salmon, 7 not information; altogether 8349 fish. The number of previous spawners was 270. The total numbers of fish scales to be measured is approx. 6983 (previous spawners and escaped salmon excluded). The total number of fish for genetic analysis is 7250 fish (only first time spawners and previous spawners) Plan for 2012 - coastal sampling Norway List of fishermen – dead line in March 2012, FMFi will arrange individual contracts with participating fishermen. NB: Migratory pattern, spatial and temporal coverage, district distribution (coastal and fjord fishery) – plan the sampling on the basis of results from 2011. Discussion and questions: UTU has budgeted analyses of 12 000 adult scale samples (6000/ year). By today UTU has received approx. 7250 samples for DNA analysis. By today UTU has processed approx 3000 adult scales from 2011 and by the February meeting the number will be approx. 4000. These 4000 fish will be used to plan coastal sampling for 2012, with the extended 18 marker baseline. IMR will deliver the extended 18 marker baseline to UTU before 31.1 for assignments of the 4000 adult salmon. The planned 6000 scales will be ready in the course of May 2012, before new 2012 coastal samples start coming in. The price for additional samples over the planned 12 000 is approx. 9 €/ sample: approx. 1250 more samples were delivered in by fishermen in 2011. UTU has budget to analyse 5000 samples from 2012 catches in 2012 – if no additional funding is available. Important to have optimal spatial and temporal coverage in the adult sampling because of the plan to describe the migratory behaviour of different salmon stocks in the project area. Rivers – sampling of juvenile baseline in 2011 Russian juvenile baseline sampling – status and numbers Sergey Prusov reports on the Russian baseline sampling. Baseline sampling in 2011 was conducted in the rivers of Murmansk oblast, Archangelsk oblast, Karelia and Komi Republics. Number of samples: Kola Peninsula – 13 rivers (1050 samples), Karelia – 1 river (40 samples), Pechora – 2 rivers (100 samples), Severnaya Dvina – 3 rivers (40 samples), Kuloy – 3 rivers (80 samples). In total: 1300 samples in 2011. Number of samples collected 2001-2011: 2001-2007 – 3 rivers (130 samples), 2008 – 12 rivers (1000 samples), 2009 – 33 rivers (2500 samples), 2010 – 10 rivers (500 samples), 2011 – 22 rivers (1300 samples). In total Russia up until today: 80 rivers (5400 samples). Sergey will compile and circulate list of Russian rivers sampled and rivers to be sampled. Plan for baseline sampling in 2012 – Russia In general the Murmansk area has good coverage, 2 more rivers between Pyalitza and Ponoi will be sampled in 2012. Towards the White Sea coast still 5-6 rivers will be sampled in 2012 (the status will then be total of 20 rivers for this area). River basin of Mesen - 10 rivers to be sampled in 2012, the plan is to have 5-600 samples. Also rivers in the region of Karelia remain to be sampled. Analysis of the Russian baseline samples has priority, also with regards of the ‘gen map’ action. If there is need to reduce analysed numbers, reduce first in the coastal/ estuarine samples in the Russian material. Norwegian juvenile baseline sampling – status and numbers Referring to earlier documents circulated by Eero Niemelä concerning the Finnmark and Troms baseline numbers. Collected in 2009: 1044 samples from juvenile salmon in Finnmark; in 2010: 3350 samples from juvenile salmon in Finnmark; in 2011: 2350 samples from juvenile salmon from 3 rivers in Finnmark and from 27 rivers in Troms. In addition in 2011 it was collected: 3130 samples from salmon juveniles from the 20 biggest salmon rivers in Finnmark for Øystein Skaala (IMR). This material is used for the analysis of the possible effects of escaped salmon on the juvenile production. Altogether 6744 samples (not including samples to Øystein Skaala) has been collected by Fylkesmannen i Finnmark/FGFRI in 2009-2011 from Finnmark and Troms. Number of samples collected by NINA in year 2011: rivers in Nordland – 20. Nordland rivers – Roksdal, Saltdal, Beiar are sampled and analyzed baseline in IMR. IMR keeps a list of all sampled rivers + rivers planned to be sampled in 2012 in the project area. The list/ data base also include info on the number of markers they are analysed with. This list will be put on the share point when it is ready. 2 Plan for baseline sampling in 2012 – Norway Nordland rivers to be sampled – approx. xx rivers. Troms rivers to be sampled – maximum 5-6. Finnmark rivers to be sampled – maximum 7-10. Discussion and questions: Further strategy for the baseline analysis – towards the February meeting Currently at IMR: approx. 135 rivers/ sites. More rivers from Nordland, Troms and Russia will arrive in 2011/ 2012. IMR has budgeted analyses of maximum 150 rivers. As it now looks approx. 180 rivers will be sampled in the course of the project. Prioritising of rivers will be necessary, depending on regional coverage, smolt production and attainable precision in the assignment etc. River priority and strategy towards February 2012 meeting+ background for the plan for the coastal sampling in 2012; 1) Improve areal/ regional coverage: by expanding the baseline analyse rivers in Troms 9 (+ 2 rivers already ready in UTU – total 11 rivers to February). Improve the areal coverage both in Russia (Dvina, Mesen, Pechora – Eastern Russia – Karelia 1 Keret River), at least with the 18 markers. White Sea rivers – Umba, Varzuga, Kovda, Kitsa, Kanda (+ 5-6 more rivers will be sampled in 2012). Take the largest populations in the area as an addition to the 18 + marker baseline; 2) Combine all existing baseline for some areas with the 31marker system already in UTU and IMR – f.
