Characteristics of coastal fish in the bays of Eastern Murman during summer 2020

Abstract

In the article was considered species composition of fish in the littoral and sublittoral zones of Yarnyshnaya and Zelenetskaya bays (Barents Sea) during summer 2020. For the first time, the kelp snailfish Liparis tunicatus was recorded in the studied water area. At whole was discovered 15 species of fish and most abundent between them is staghorn sculpin Gymnocanthus tricuspis and shorthorn sculpin Myoxocephalus scorpius. Also quantitative characteristics of the distribution for each fish species are represented. The dynamics of abundance and diversity of coastal fish communities were analyzed. Comparing of perennial data with 2020 indicates that at the present observed relatively rich species composition, low fish distribution density, low abundance of young Gadidae, but high indicators of biodiversity in coastal communities.
