Northern Shrimp (Pandalus borealis, Krøyer) from Spanish Bottom Trawl Survey 2006 in NAFO Divisions 3LNO

The Spanish Institute of Oceanography carried out in 2007 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 the same series. In 2007 the catch (71 kg.) and estimated biomass (401 tons.) confirm the decrease of shrimp importance from 2004 in 3NO. In 3L Division, since the beginning of the new survey in 2003 and after of years with consecutive and constant increase the estimated biomass in 2007 decreased about 10% with respect to last year. Catch results from the surveys and data analysis are discussed in this paper
