Data on the distribution and ecology of darkfin sculpin Malacocottus zonurus (Psychrolutidae) off Middle Kuril Islands
Abstract
Data on the occurrence, distribution, and some aspects of ecology of the darkfin sculpin Malacocottus zonurus in Pacific waters off the Middle Kuril Islands are presented based on materials collected during monitoring of bottom trawl fishing. It is shown this species to be a regular bycatch from April to July at the depths 100–520 m with bottom water temperatures of 1.8–3.9 °C. The greatest abundance of the species was recorded in the bathymetric range of 301–400 m. It is assumed that off the Middle Kuril Islands, as in other region of habitats, juvenile M. zonurus prefers greater depths, unlike adults, which can be numerous in lower shelf areas.
