Press Release – US Pacific Fishery Managers Vote to Prohibit Wire Leaders and Remove Trailing Gear in New Shark Conservation Measure (22 June 2021)

Press Releases

​HONOLULU (22 June 2021) The Western Pacific Regional Fishery Management Council voted today to prohibit wire leaders in the Hawai‘i deep-set longline fishery and require removal of trailing gear for all longline vessels operating under the Pacific Pelagic Fishery Ecosystem Plan to improve the post-hooking survivorship of oceanic whitetip sharks.

Oceanic whitetip sharks are listed as threatened under the Endangered Species Act and are subject to overfishing and overfished in the Western and Central Pacific Ocean (WCPO), primarily due to foreign fishing. U.S. longline impacts on oceanic whitetip sharks are only about 6% of the catch in the WCPO. Recognizing the low impact on the stock, the Council previously recommended that wire leader usage be reduced in international longline fisheries.

Available scientific information supports the fishing gear change from steel wire to monofilament nylon leaders to facilitate a shark’s ability to free itself from an accidental hooking by biting through the line. The measure is expected to reduce the oceanic whitetip shark catch and mortality by about 30%.

This conservation effort was initially developed by the Hawaii Longline Association (HLA) as a voluntary transition presented at the Council’s December 2020 meeting. Since wire leaders are used as a safety measure to prevent fly-back of the weighted swivel, HLA will provide crew with training on shark handling and safety protocols. The Council emphasized the importance of balancing crew safety with the requirement to remove trailing gear, and recommended that fishermen target removing trailing gear down to less than 1 meter (about 3 feet), only if it is safe to do so.

The Western Pacific Region has two other active longline fisheries—the Hawai‘i shallow-set and the American Samoa longline fisheries—both of which already use nylon leaders. For this reason, the Council’s action focused on prohibiting wire leaders in the Hawai‘i deep-set longline fishery, but the trailing gear requirement applies across the board.

The Council recognized that the wire leader prohibition would also reduce the already low interactions with silky sharks in U.S. longline fisheries. The WCPO silky shark stock is experiencing overfishing, but not overfished. The relative impact of the U.S. longline vessels is estimated at 0.8% of WCPO catches based on observer data and 0.4% based on market data.

The United States has a much higher observer coverage than most countries fishing in the WCPO, with 100% observer coverage in the Hawai‘i shallow-set longline fishery, and 20% in the Hawai‘i deep-set and American Samoa longline fisheries. The international target is 5%.

The Council concluded the first day of its three-day virtual meeting today with discussions and recommendations regarding pelagic and international fisheries. The meeting continues through June 24, 2021, by web conference (Webex). Instructions on connecting to Webex, agendas and briefing documents are posted at
