摘要
Based on the results of bottom trawl surveys, the distribution and some aspects of biology of Lycodes cf. brashnikovi Soldatov, 1918 off the Pacific coast of Kamchatka are considered. In summer, main accumulations of this species are noted in Kronotsky Bay, and are rare to the south from 52° N. The bathymetric range of occurrence of the species is 83–202 m; the largest catches are typical for the depths of 100–180 m. The maximum length of L. cf. brashnikovi in Pacific waters is 53 cm, weight, 554 g. According to the degree of maturation of the gonads in summer, the species reproduces in the autumn–winter period. Critical analysis of the literature and original data, currently the genus Lycodes off the Pacific coast of Kamchatka is represented by five species, among L. cf. brashnikovi is the most abundance species in the eulittoral zone.
