WWF-Russia increases the number of fishing companies covered with observations
The observers spent 240 days on the board of three longline fishing vessels. The vessels were fishing for cod and halibut in the northern part of the Sea of Okhotsk, in the areas near Sakhalin Island and the North Kuril islands, and in the western part of the Bering Sea.
The main goal of the observers’ work was to collect data for assessing commercial fish stocks conditions. At the same time, the observers were registering incidents of seabird mortality and streamer-line usage. The observers monitored about 400 fishing operations onboard. According to the provided data, the major part of the operations was conducted using single and double streamer-lines.
The effectiveness of streamer-lines as the mitigation devices has been proven many times before. According to scientific data, the double streamer-line lowers bird mortality by more than 90%. It also saves the bait increasing catch per unit of effort making fishing operation more profitable for the fishermen.
