HYDROLOGICAL CONDITIONS AND CATCHES OF BENTHIC FISHES IN SOUTHERN BERING SEA (Gidrologicheskie Usloviya i Ulovy Donnykh Ryb v Yuzhnoi Chasti Barentseva Morya)
The anomaly of water temperature in layer 0-200m along the Kola meridian from 70 degrees 30 minutes N to 72 degrees 30 minutes N, based on mean temperature during 1950-1965, was considered to be the variation index of heat conditions in the Barents Sea. In accordance with the heat conditions of the...
