The development of the international shrimp (Pandalus borealis) fishery in NAFO Division 3M is described. Various indices show that even the stock was in high levels in 2006 and 2007 the lack of good recruitments in the last years and the progressive disappearance of the strong year classes 2001 and 2002 have caused a drastic decline of the stock. Although the effort in the last years was low due to high cost of oil and low marketing prize of shrimp, the increase of cod biomass (the most important predator of northern shrimp in 3M) has probably been the cause of the successive bad recruitments and resulting decline of the stock. The revised Nominal catches declined from 63970 tonnes in 2003 to 12889 tonnes in 2008. The catch in 2009 was only 2958 tonnes to 10 september. Noting the lack of reports on catch this figure might increase although is very unlikely that the catches exceed the 5000 tonnes. The results from ageing which is based on biological sampling showed a great number of five ...
