The results of the Russian and Norwegian surveys for shrimp, Pandalus borealis, in the Barents sea in spring and the Svalbard area in autumn 1991 are presented in this paper. The survey results are presented by nation but the discussion is given combined. The results show that the data from both countries show similar trends. They indicate that shrimp biomass in the area of the joint research activities has increased, especially in the areas north of 74°N and east of 25°E. The norwegian data indicate that the shrimp biomass in the western Barents Sea is at the level of last year. A slight decrease in the biomass is observed in the southemmost areas of the Barents Sea. A decrease in biomass is observed in the areas west of 25°E and north of 73°N, that is in the Svalbard region.
