By-catch of macrozoobenthos in ichthyological bottom trawling as index of trawling intensity

The impact of bottom trawling on macrobenthic fauna has been investigated in this work. Species composition and abundance of macrozoobenthos by-catch from the ichthyological bottom trawling have been described. The influence of bottom trawl fishery intensity on by-catch biomass of bottom invertebrates have been analyzed. The significant relationship of inverse order between the intensity of trawling and the biomass of macrozoobenthos has been shown.

Frequency of feeding activity of red king crab Paralithodes camtschaticus (Arthropoda, Decapoda) in the Barents Sea

The paper presents the results of studies of feeding rhythmicity of the red king crab in the Barents Sea. The presence of circadian and monthly periodicity in feeding activity of king crab has been shown. The specified periodicity is associated with the tidal cycle. The value of the total index of fullness of crab stomach follows the heights of the tide with a small lag. The highest average daily catches of traps reflecting the high feeding activity of crab are recorded during spring tides.
