Observers assessed the effectiveness of streamer-lines

26 february 2019
Thanks to streamer-line implementation, the fishermen saved more than 800 birds during the two-month sailing.

For more than two months, two observers monitored operations onboard longline vessels fishing for cod and halibut in the Sea of Okhotsk, the Bering Sea and the Pacific Ocean. The observers were counting seabirds and marine mammals encountered during the sailing period, as well as reporting incidents of seabird mortality caused by fishing activity.

The average number of birds killed during fishing operations on each vessel was forty-five, with ninety-one killed in total. Experts say this is a fairly low number and is considered to be the result of streamer-line usage. The fishermen used double streamer-lines to improve the effectiveness of these mitigation devices. No endangered species were harmed during the sailing period.

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%.
