Assessment of the International Fishery for Shrimp (Pandalus borealis)in Division 3M (Flemish Cap), 1993-2014
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...

The low exploitation rates in the recent past years and the moratorium in 2011-2014 have not provoked changes in the state of the stock. Also the recruitment prospects remain uncertain and therefore the fishing mortality would be set as close to zero as possible in 2015.
