ICES  advises  that  when  the  MSY  approach  is  applied,  total  commercial  sea  catch  in  2016  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 2016.  
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. Inorder  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.
