MetadataShow full item record
In 2011 Fisheries Commission Working Group of Fishery Managers and Scientists on Conservation Plans and Rebuilding Strategies (WGFMS-CPRS) reviewed the cod 3NO Conservation Plan and Rebuilding Strategy (CPRS) and proposed a new one that was approved by the Fisheries Commission in 2011. The new reference points values approved for the 3NO cod CPRS were the following: Blim = 60,000 t, Bisr = 120,000 t, Flim = 0.30 and Bmsy = 248,000 t. Concerns were raised on the high uncertainty and the lack of confidence intervals of the reference points. The WGFMS-CPRS agreed that the values of Bisr and Bmsy should be further reviewed by the Scientific Council and the Fisheries Commission. In 2012, Scientific Council noted that: the approach used in estimation of the maximum sustainable yield (MSY) reference points may not be advisable in the case of Div. 3NO cod due to the high uncertainty in the stock-recruit relationship for this stock. Scientific Council recommends the use of proxies based on the ...
