Results of stratified random bottom trawl survey in the Barents Sea in April - May and the Svalbard region in July August 1989 are described. However, the strata south of Bear Island were surveyed in July- August 1989. Based on data from 123 trawl stations in the Barents Sea survey, the biomass of shrimps was estimated to about 173 800 tonnes, which is an increase of 11.6% compared with 1988. Based on data from 62 trawl stations in the Svalbard region, the biomass was estimated to about 44 000 tonnes, corresponding to an increase of 56.4% compared with 1988.
