Research survey information regarding northern shrimp (Pandalus borealis) in the Barents Sea and Svalbard area

The geographical distribution of the stock in 2008 is similar to that of the previous year. The estimate of mean biomass increased by about 40% from 2004 to 2006 and then decreased again to slightly below the 2004 value. Overall size distributions indicate a relatively large amount of smaller shrimp in 2004 which resulted in the increase in stock biomass until 2006. The recruitment index decreased since 2004. The new 'ecosystem survey' has not been calibrated to the 'shrimp survey' which was discontinued in 2004.
