The paper presents the results of microbiological studies carried out in the Motovsky Bay (2017) and the northeastern part of the Barents Sea (2020) in October. It was shown that, with comparable values of abundance, the biomass of bacterioplankton in open waters was slightly higher than in coastal waters. The quantity was 148–717 thousand cells/ml in Motovsky Bay and 170–957 thousand cells/ml in the open water area. The biomass was 7.26–29.07 mg/m3 in Motovsky Bay and 9.71–51.39 mg/m3 in the open water area. The maximum values were in the 0–50 m layer,the minimum – in the bottom layer in both areas. Those results supplement the existing understanding of bacterioplanktons development and distribution in the Barents Sea in the autumn season.

Spawning Stock

Prior to the 1920s, the northeast Arctic (NA) cod were caught at spawning grounds ranging from the southernmost to the northernmost parts of the Norwegian coast, but have for the last 50 yr mainly been caught around the Lofoten archipelago and northwards. The NA cod have their feeding and nursery grounds in the Barents Sea, and migrate south towards the Norwegian coast in the winter to spawn. This study uses commercial fisheries' data from landing ports along the entire Norwegian coast during the period 1866–1969 as evidence of long-term truncation and northerly shift of spawning grounds. Nearly all spawning grounds south of Lofoten have been abandoned, while an increasing proportion of the spawning stock only uses the northernmost areas of the Norwegian coast, Troms and Finnmark. The truncation can hardly be attributed to long-term climatic variations, but may result from an intensive size-selective trawl fishery in the Barents Sea causing a sudden increase in fishing mortality, probably altering the size structure and migratory capacity of the stock.

New findings of four gastropod species: Melanella laurae, Hemiaclis ventrosa (family Eulimidae), Chrysallida sublustris and Odostomia acuta (family Pyramidellidae) are described. O. acuta was previously confused by Russian authors with H. ventrosa, distribution of both species in the Barents Sea is limited to the coastal waters of Finmark and Murman. M. laurae and C. sublustris were found for the first time in the adjacent to the Barents Sea parts of the Arctic Ocean.

The paper describes species composition, distribution and biology of the polychaeta genus Pholoe in the north-east region of the Barents Sea (between Franz Josef Land and north-west coast of Novaya Zemlya archipelago). One species of the genu s was identified based on the reviewed morphological descriptions – Pholoe assimilis. The highest values of population density (1130 specimens/m2) and biomass (570 mg/m2) were registered in comparatively warm coastal waters of Novaya Zemlya archipelago. Pholoe assimilis’ population size structure based on the dorsal width of the fifth chaetiger was investigated for the first time. Size-frequency histograms indicate presence of at least four size classes.
