Captures of Pacific halibut Hippoglossus stenolepis (Pleuronectidae) in Anadyr estuary of the Bering Sea

Pacific halibut Hippoglossus stenolepis is registered in the Anadyr estuary (Bering Sea basin) for the first time: 20 specimens, 18.5–160.5 cm in length, were caught by trawl and longline within the sea portion of the Anadyr River estuary in August 2010 and September 2015 in highly desalted (23.5‰ on average) and heated (6.5°С) water at a depth of 14–30 meters. Halibut is suggested to form feeding groups within the Anadyr Estuary. An opportunity for organized fishing in this region is discussed.
