Agreement on the Conservation of Albatrosses and Petrels

Japanese fishing master wins WWF Smart Gear prizes for double-weight branch line to save albatrosses and petrels

The prize-winning entries for the WWF 2011 International Smart Gear Competition were announced at the Pacific Marine Expo in Seattle, Washington, USA on 17 November this year.  Winning both the Grand Prize (US$ 30 000) and this year's Special Tuna Prize (US$ 7500) from the International Seafood Sustainability Foundation (a coalition of tuna processors, leading scientists and WWF) was an entry from Captain Kazuhiro Yamazaki, Fishing Master of the tuna longline vessel Fukuseki Maru No 5.

His design is called the ‘Yamazaki Double-Weight Branchline' and works by increasing the sinking rate of pelagic longlines, making it more difficult for seabirds to get caught on the baited hooks.  It also reduces injuries and fatalities to fishing crew caused by rapidly recoiling weights and hooks.  Used in conjunction with bird-scaring (Tori) lines and night setting it can reduce seabird mortality during pelagic longlining by 89%, based on research conducted in the South African tuna joint venture fishery.

"The Yamazaki Double-Weight Branchline is an innovation that meshes practicality and safety with function and conservation and breaks down the barriers to the adoption of branchline weighting as a seabird bycatch mitigation measures in world tuna commissions (RFMOs) and in domestic fisheries."

Yamazaki-san was at sea fishing in the Indian Ocean at the time of the Expo and so was unavailable to accept his awards in person.  However, Mr. Tokuichi Nishikawa, Chairman of Fukusekimaru Fisheries, accepted the award on his behalf from Dr John Stein, Acting Science Director of the Northwest Science Center, NOAA Fisheries Service in Seattle.  Mr Yoshida of the Federation of Japan Tuna Fisheries Cooperative Associations (Japan Tuna) translated Nishikawa-san's acceptance speech.
