Description
Summary:The Spanish Institute of Oceanography carried out in 2009 two bottom trawl surveys in the NAFO Regulatory Area in Division 3NO and 3L during the months of June, July and August respectively. The results on Northern shrimp (Pandalus borealis) are presented and compared with those from previous surveys from the same series. In 2009 the catch (33 kg.) and estimated biomass (139 t.) confirm the decrease of shrimp importance from 2004 in 3NO. In 2009 the biomass estimated of northern shrimp in 3L Division was 74091 t. showing a drastic decline (50% with respect to 2008) after the upward trend a long the whole period studied. Catch results from the surveys and data analysis are discussed in this paper.
