August 13, 2019 — SEAFOOD NEWS — Hawai’i swordfish fishermen finally have a plan for loggerhead and leatherback sea turtle bycatch. The Western Pacific Regional Fishery Management Council finalized new mitigation measures last week for the shallow-set longline fishery, after waiting for the completion of a new biological opinion for more than a year.
Hawai’i-based longliners provide nearly half of the domestic swordfish to the U.S. market.
The amendment to the Pelagic Fishery Ecosystem Plan sets an annual fleet-wide hard cap limit on the number of leatherback turtle interactions (hooked or entangled) at 16. The Council did not recommend setting an annual fleet-wide hard cap for loggerheads in light of that species’ improving population trends and other mitigation measures, but the Council retains the authority to set a hard cap limit in the future if necessary. The Council noted that few interactions lead to serious injury or mortality of the animal, which is normally released unharmed.
To limit the impact of interactions on sea turtles and to promote year-round fishing opportunities, the Council further recommended the establishment of individual trip interaction limits of five loggerheads and two leatherback turtles. Once a vessel reaches either of these trip limits, the vessel is required to return to port and will be prohibited from engaging in shallow-set longline fishing for five days after returning. This action is expected to allow sea turtle “hot spots” to disperse, while encouraging fishermen to take action to avoid sea turtle interactions before the trip limits are reached, the Council said in a press release.
Additional restrictions set trip limits on each vessel. Any vessel that reaches the trip limit twice for either leatherback or loggerhead sea turtles in a calendar year will be prohibited from shallow-set longline fishing for the remainder of that year. The following calendar year, these vessels will have an annual vessel limit equivalent to a single trip limit – either five loggerheads or two leatherbacks. These additional vessel restrictions are measures required under the new BiOp prepared by NMFS.
The Council’s Scientific and Statistical Committee noted in its report that in light of the BiOp finding that the fishery does not jeopardize the continued existence of these sea turtles, the additional restrictions are punitive. Furthermore, they are not supported by the scientific information that show the fishery has no adverse impacts to the overall loggerhead and leatherback populations.
NMFS Pacific Islands Regional Office Regional Administrator Michael Tosatto reminded the Council that it is the Council’s “mandate to minimize interactions with protected species … minimize means approach zero,” according to the press release.
“You’ve heard the expression barking up the wrong tree – we’re swimming in the wrong ocean,” Council member Ed Watamura, said in the statement. He noted the disproportionate impact the Hawai’i fleet experiences due to the U.S. government’s strict regulations, while foreign fleets have much more impacts to sea turtles. With almost 100 percent of the incidentally hooked turtles returning to the ocean alive, the Hawai’i swordfish fishery has had negligible impact on the leatherback and loggerhead turtle populations in the Pacific Ocean.
Furthermore, threats to loggerhead and leatherback turtles in other parts of the populations’ range include bycatch in artisanal and coastal fisheries in the Western Pacific, direct harvesting of eggs and adult turtles, nest predation by feral animals, beach nesting habitat alteration, and climate change.
The Council did not recommend setting a fleet-wide interaction limit for loggerhead turtles, recognizing that the status of the population has improved since the Council first recommended implementing hard caps for the shallow-set longline fishery in 2004, according to the press release. A recent population assessment of the North Pacific loggerhead turtles showed the population is growing at an annual rate of 2.4 percent, and the total is estimated at 340,000 individuals. Considering this population growth and the additional restrictions on trip limits, the Council found the fleet-wide hard cap limit for loggerhead turtles is no longer necessary or appropriate to conserve the species.
Final action taken yesterday by the Council was a culmination of a nearly two-year process to improve measures for managing loggerhead and leatherback turtle interactions in the shallow-set longline fishery. The process was stalled for nearly a year due to NMFS’ delay in completing the new BiOp, which was originally scheduled to be completed in October 2018. The Council’s final recommendation will be forwarded to the Secretary of Commerce, followed by a rule making process including a public comment period.
