In the North Atlantic, the nominal catch of Atlantic salmon in 2009 (1300 t) was the lowest in the time-series. Marine survival remains low. Northern North-East Atlantic Commission stock complexes (1SW and MSW) are at full reproductive capacity prior to the commencement of distant water fisheries. Southern European 1SW stock complex is considered to be suffering reduced reproductive capacity. Southern European MSW stock complex is considered to be at risk of suffering reduced reproductive capacity. The current estimates for both stock complexes are amongst the lowest in the time series. Estimated exploitation rates have generally been decreasing over the time period for both 1SW and MSW stocks in Northern and Southern NEAC areas and in North America. Despite management measures aimed at reducing exploitation in recent years there has been little improvement in the status of stocks over time. This is mainly because of continuing poor survival in the marine environment attributed to climate effects. Efforts ...
