4 Map from The Status of the Wild Atlantic Salmon a river by river assessment

5 International a arena a Atlantic ta tc salmon (incl Baltic salmon) NASCO (North Atlantic Salmon Conservation Organisation) (committees for North-West Atlantic, Greenland, North-East Atlantic) - Situation in many countries very critical (e g US, Canada) (Russian Kola peninsula still strong populations) - NASCO Stopped all open-sea salmon fisheries (Completely other management views compared to Baltic salmon) - NASCO apply model for management based on river population management 5

6 - Big problems with unintentional escapes from salmon fish- farming. - Strayers-escapees (0,5 million) (farmed salmon) migrate to rivers, and mix with wild populations - Compare to Baltic Sea, 5-6 million smolts released every year - Released salmon (compensation for hydro-power construction) for open-sea fisheries Conclusion: Baltic Salmon management has a lot to learn from Atlantic salmon management 6

7 International Baltic salmon management IBSFC (International Baltic Sea Fishery Commission)(closed i in 2005) ) Baltic Salmon Action Plan (SAP) The SAP was adopted in 1997 to support the sustainable management of the Baltic salmon and to secure the survival of the wild Baltic salmon populations. SAP goal:reach 50 % of the potential salmon production in each salmon river by

8 Baltic Salmon action plan (SAP) CCB proposal p - needed to decide on complementary goals and new actions to be included into the Baltic SAP. Redefinition of objectives for the SAP, in accordance with ICES advice ICES has proposed IBSFC to redefine the objectives for Baltic salmon management (2003) to include - Safeguarding genetic variability - Safeguarding each wild stock including the weakest 8

9 EU (European Union) EU start work for Baltic Salmon Action Plan in 2007/2008 BS RAC (Baltic Sea Regional Advisory Council for fisheries) (Fishing industry, Other interest t groups) -give advice on fisheries to EU -CCB is one NGO-partner -BS RAC Working group Salmon Discuss Baltic salmon in November 2006-early 2009 Provided advice to EC DG Fisheries, April 07 and May 09 EU Present a new Baltic Salmon Management Plan in spring

10 Baltic Salmon - conservation status favourable? Atlantic (Baltic) salmon a species of special interest in EU Habitat directive. Endangered or vulnerable; rare; endemic or require particular attention Wild salmon shall reach Good favourable conservation status Status described as non-favourable in Boreal region today Obligation for all EU-members to fulfil EU Habitat directive. 10

11 Studies - Genetic Lax: Material variability och metoder for Baltic Salmon Salmon populations p from Northern Europe (46 respectively 38 populations, approx. 50 ind/population) Genetic markers : mtdna respectively Micro-satellites 11

12 Main Results: Clear separation between the Baltic and Eastern Atlantic salmon populations p 12

13 Main Results: ND1 variation supports the hypothesis of postglacial colonization of the Baltic Sea by multiple lineages 13

16 Salmon: microsatellite variability 16

17 Conclusion Genetic variability: Baltic salmon : at least two colonization routes to Baltic Sea (via Barents Sea & North Sea) Wild Baltic salmon genetic variability today, reflects historical colonization routes after Ice age Knowledge of various Genetic units Basic data for Salmon conservation goals 17

18 Baltic Salmon situation today Salmon quota (TAC) salmon (year 2008) in Baltic Main basin (reported in year 2008) in Gulf of Finland (landings in 2008) Fisheries open-sea 24 % (mainly by Pol, Den, Fin, Swe) coastal 51 % rivers approx 25 % Farmed and released salmon 6-7 million per year Production from Natural spawning mainly in a few river in Bothnian Bay increased considerably last years ( approx. 2 million smolts per year) 18

19 Improper commercial fishing policies, and extensive artificial salmon stocking programmes threaten the naturally spawning Baltic salmon. 2/3 of all wild Baltic salmon river populations are threatened (26 river populations ) 19

21 ICES advice for Baltic salmon management for 2007 Main Basin and Gulf of Bothnia - Strong salmon stocks in northern Baltic: Current exploitation will not impair possibility to reach 50 % production goal - Status of less productive wild stocks is poor, especially in Southern Baltic - negative trend in smolt production observed in Southern Baltic (increased post-smolt smolt mortality during past decade) (Southern Baltic has high proportion of overall genetic variability of Baltic salmon stocks) 21

26 ICES advice for Baltic salmon management for 2007 Gulf of Finland - wild salmon stocks very critical situation -Native salmon populations in at least 3 Estonian rivers (genetically distinct from each other) Another 6 wild Estonian rivers supported with smolt releases - Russian Luga river native population, and smolt releases - Poaching a big problem -Recovery programmes should be developed for all rivers -Finland no wild salmon rivers in GoF 26

27 Gulf of Finland 27

28 No regulation of Baltic sea-trout fisheries No TAC for sea-trout in Baltic No minimum landing size of seatrout(for salmon min. landing size is 60 cm) Consequence is no limits for sea- trout landings & salmon landings-pol 28

30 Classifying salmon as sea- trout result in no-limits for salmon fisheries Fisheries inspection in Gdynia do not distinguish salmon/sea-trout Most probably misreporting in Polish salmon/sea-trout landings Polish misreporting can correspond to salmon/year EC must develop a control of landings that distinguish between salmon and sea-trout to t 30

35 HELCOM Salar a project in Overview of the state of salmon and sea trout stocks in Baltic rivers Develop a Baltic Sea salmon/sea trout river inventory and classification, incl. proposals for some actions - National salmon experts needed for the HELCOM work -Time-table, Febr Nov

36 Salmon fisheries es management age e Fishing in salmon rivers and river-mouths must be restricted and controled carefully each year, and should not be opened until a controled amount of returning spawners (male and female) have reached its spawning grounds for a sustained river population. 36

37 Important components for a Salmon River Management Plan Clear Salmon Management Goals *Production of naturally spawning Baltic salmon shall gradually increase to attain by 2015 a production of wild Baltic salmon of at least 75 % of the estimated potential. *Minimum of spawners returning to and spawning at the spawning areas of each individual river, without support from released salmon. 37

38 Salmon river management plans *Annual standard monitoring of - returning salmon spawners -downstream migration of smolts to Baltic Sea -river water quality data - efficiency of existing fish-ways -proportion of strayers and genetic composition of the populations *Habitat protection/restoration - mapping of important spawning and breeding areas - plan for and implementation of protection/restoration of 75% of the potential spawning and nursing grounds in each 38 individual river

39 *Harvest - fisheries regulations in the river/river mouth that will guarantee a minimum of returning spawners, and the 75% goal of the estimated potential production in each individual river -fisheries regulations should guarantee spawning of both early and late migrating spawners *Control - development of appropriate fisheries control measures to support the salmon management targets - effective control of illegal salmon fisheries - development of regulations for all salmon fisheries(incl. recreational fishing and fishing 39 tourism )
