Макрозообентос шельфа Камчатского залива по данным 2002 г.

The taxonomic composition of the bottom fauna was identified on the data of dredge survey carried out at 11 stations in 2002 in Kamchatka Gulf at depths of 24–200 m. The distribution of macrozoobenthos biomass and its taxonomic structure are compared with the data of 1950s and 1986. The distribution of biomass and taxonomic structure of macrozoobenthos are given in comparison with the data of 1950s and 1986. It is shown that on the bottom areas surveyed in 2002, coinciding with the bottom areas studied earlier, faunal complexes identified by biomass have a similar appearance and comparable biomass. Thus, the highest biomass of macrozoobenthos was observed in the southwestern part of the gulf, the lowest – in the desalinated area near the mouth of the Kamchatka River. The distribution of bottom communities was highly mosaic.
