Northern Shrimp (Pandalus borealis, Krøyer) from Spanish Bottom Trawl Survey 2012 in NAFO Div. 3LNO
The Spanish Institute of Oceanography carried out in 2012 two bottom trawl surveys in the NAFO Regulatory Area in Division 3NO and 3L during the months of June and August respectively. The results on Northern shrimp (Pandalus borealis) are presented and compared with those from previous surveys from...
