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

The Spanish Institute of Oceanography carried out in 2006 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. While the catch (278 kg.) and estimated biomass (1300 tons.) confirm the decrease of shrimp importance from 2002 in 3NO, 3L showed since the beginning of the new survey in 2003 a constant and significant increase from 104551 tons. in 2003 to 215389 tons. in 2006. Catch results from the surveys and data analysis are discussed in this paper
