NEAR-VESSEL SEABIRD AGGREGATIONS IN THE WINTER TRAWL FISHERY OF POLLOCK IN THE OKHOTSK SEA
At least 12 seabird species aggregated permanently around the vessels of pollock trawl fishery in the Okhotsk Sea in January-April, 2015. They were attracted by the fish processing waste and small-sized fish falling from trawls. Fulmars dominated in all fishery districts except the East-Sakhalin sub...
