ICES advises that new data (landings and surveys) available for this stock do not change the perception of the stock status. Therefore, the advice for this stock in 2017 is the same as the advice for 2016. The assessment was not updated in 2016, but some information on catches in 2015 is provided.
ICES advises that when the maximum sustainable yield (MSY) approach is applied, total commercial sea catch in 2017 should not exceed 116 000 salmon. Applying the same catch proportions estimated to have occurred in 2014, this catch would be split as follows: 10% unwanted catch (previously referred to as discards) and 90% wanted catch (77% reported, 7% unreported, and 6% misreported). Setting a TAC under a discard ban needs to take account of wanted and unwanted catch. In setting the TAC, consideration should also be given to expected unreporting and misreporting levels in 2017.
ICES advises that management of salmon fisheries should be based on the status of individual river stocks. Fisheries on mixed stocks that cannot target only river stocks with a healthy status, present particular threats to stocks that do not have a healthy status. Fisheries in open-sea areas or coastal waters are more likely to pose a threat to depleted stocks than fisheries in estuaries and rivers. Effort in these mixed-stock fisheries has been reduced to low levels and should not increase.
Salmon stocks in the rivers Rickleån, Kågeälven, and Öreälven in the Gulf of Bothnia, Emån in southern Sweden, and in several rivers in the southeastern Main Basin are especially weak. These stocks need longer-term, stock-specific rebuilding measures, including fisheries restrictions in estuaries and rivers, habitat restoration, and removal of physical barriers. In order to maximize the potential recovery of these stocks, exploitation should not increase along their feeding and spawning migration routes at sea. The offshore fishery in the Main Basin catches all weak salmon stocks on their feeding migration. The coastal fishery catches weak stocks from northern rivers when the salmon pass the Åland Sea and the Gulf of Bothnia on their spawning migration.
