Abstract
Based on results of the bottom trawl surveys on the shelf of the Petropavlovsk-Commander subzone in 1999, 2002, 2016–2018, three standard grounds of similar square were outlined: in Kronotsky Bay, in the northern part of Avachinsky Gulf and near Southeast Kamchatka. Data about species composition of marine fish in the catches in the whole area of the research, about average density of aggregations, distribution, stock abundance and biomass of major commercial fish species on the standard grounds are demonstrated by years of the research. Length-age composition and number by age groups is demonstrated for Alaska pollock and Northern rock sole. Using the results is planned as indexes in adjusting model calculations.
