Change Is in the Air: Western Pacific SSC Suggests New Approaches for Suite of Issues

March 19, 2019 — SEAFOOD NEWS — The Scientific and Statistical Committee of the Western Pacific Regional Fishery Management Council concluded a three-day meeting last week in Honolulu with a suite of recommendations to more effectively address issues facing fisheries in the U.S. Pacific Islands. The Council will consider those recommendations this week.

Regarding false killer whales, the SSC recommended inclusion of a population variability analysis to supplement the use of and reduce the variability of potential biological removal estimates.

The Southern Exclusion Zone (SEZ), a 132,000 square mile area in the offshore waters around the main Hawaiian Islands, was closed to the Hawai’i longline fishery on Feb. 22, 2019, after its interactions resulted in a mortality and serious injury determination for two false killer whales. With the SEZ closed, less than 18 percent of US exclusive economic zone around Hawai’i remains open to the fishery.

The SEZ may reopen in 2020 if the average estimated false killer whale M&SI in the deep-set longline fishery within the remaining open areas of the EEZ around Hawai’i for up to the five most recent years is below the potential biological removal for the species, the WPRFMC said in a press release.

The Honolulu-based longliners land about $100 million of sashimi-quality tuna, which stays principally in the state.

The PBR is defined by the Marine Mammal Protection Act as the maximum number of animals that can be removed, not including natural mortalities, from a marine mammal stock while allowing that stock to reach and maintain its optimum sustainable population, i.e., its maximum productivity keeping in mind the carrying capacity of the habitat and health of the ecosystem. The SSC recommended the Council request NMFS develop approaches to incorporate population viability analysis to supplement the use of PBR and to reduce uncertainty in PBR estimates. PVA is a species-specific risk assessment method frequently used in conservation biology.

The SSC also requested the Council ask NMFS to provide the data needed for the SSC to develop the PVA in parallel to the NMFS process. Furthermore, it also asked that NMFS develop serious-injury determination criteria for false killer whales that are probability-based. Currently, NMFS considers the impact of a false killer whale determined to be seriously injured to be equivalent to the impact of a dead false killer whale, even though animals determined to be seriously injured are released alive.

Spatial Management: A subgroup of the SSC worked to define benefits and limitations to spatial management actions relative to regional fishery issues and management objectives. The working group explored time-area closures; adaptive/real-time closures and restrictions; permanent no-take closures; and alternative non-spatial management actions, such as gear restrictions.

Members also discussed objectives of management actions, such as increasing targeted bigeye and albacore tuna abundance and reducing Hawai’i longline interactions with sea turtles and false killer whales. The group also identified criteria for evaluating the effectiveness of spatially managed areas. The SSC reviewed the outcomes of the working group and recommended that effective spatial management should have the following:

  • Objectives and performance metrics explicitly specified prior to developing a spatial management area in order to evaluate the effectiveness of the spatial management. The performance metrics should concurrently address conservation, economic and social objectives;
  • Regular monitoring of the performance of the spatial management area; and
  • Planned and tenable compliance monitoring and enforcement. The SSC said permanent closed areas are likely less effective than modifying fishing gear or methods to minimize protected species bycatch. It recommended regulations that would allow industry to find voluntary means to reduce bycatch and have input in the development of mitigation measures.

Hawai’i Kona Crab: The SSC evaluated the benchmark assessment of the Hawai’i Kona crab fishery and determined it is the best scientific information available for status determination and setting harvest limits.

The scientists said the assessment possibly accounted for a limited portion of the stock due to the small geographic extent of the commercial fishery relative to the larger distribution of the stock in Hawai’i as well as a lack of information on noncommercial fishing activities.

It suggested that female crabs discards be recorded on fishermen trip reports and that a stock assessment model be used that can account for sex-specific dynamics, since State of Hawai’i management measures allow the take of males but requires females to be discarded. The SSC recommended that the sex ratio of Kona crab at Penguin Bank be studied to evaluate the potential effects on the stock from the sex-selective fishery and reiterated its strong recommendation that extension of the closed season, changes in mesh size, retention of females and other alternative management options be evaluated to stimulate fishermen participation in this healthy fishery. Fishery participation had declined significantly after the non-retention of female Kona crabs went into effect.

U.S. Territory Longline Bigeye Tuna Quota: Regarding the federal quotas of longline-caught bigeye tuna for the U.S. Pacific Territories that participate in the Western and Central Pacific Fisheries Commission, the SSC noted that the projected impacts of allowing each U.S. Territory to transfer 1,000 or up to 2,000 metric tons of their 2,000 mt quotas to permitted U.S. longline fishing vessels would not lead to bigeye overfishing and are consistent with the Commission’s management objectives.

Satellite Study Says Tuna Longliners Vastly Misreporting Compliance with Sea Bird Avoidance

February 4, 2019 — SEAFOOD NEWS — Seabirds, in particular birds like albatross, are highly vulnerable to longlines, and in some fisheries managed by the US, take of a single bird can shut down the fishery.

The IUCN (International Union for the Conservation of Nature) lists 15 of 22 albatross species as endangered.

To mitigate bycatch, the RFMO’s in the Indian Ocean, Western Pacific, and the Atlantic have mandated measures to prevent bird interactions with longlines, such as night setting, use of weighted lines to sink faster, and use of streamers to keep birds away during setting.

However, the RFMOs depend on vessel self reporting.  Apparently a large number of vessels are lying about their mitigation measures.

According to a study of satellite data released by Birdlife International, only 15% of tuna longline vessels are using night setting, the single bycatch reduction measure most effective for albatross.

But the industry has been reporting compliance with night setting at levels between 29% and 85%, depending on the fishing area.

The study looked at satellite data for 201 vessels, analyzing their movement, speed, direction of travel and time, to determine when they were night setting.  The results showed only 15% of the vessels were actually using the practice.

The findings offered a stark contrast with reports given by countries to fisheries watchdogs that suggested night-setting was used at a much higher rate by  fleets.

“The results are very disappointing,” said Stephanie Winnard, a biologist with the albatross task force, a specialist unit set up by Birdlife International and the Royal Society for the Protection of Birds. “By this stage you would expect a lot more vessels to be using night setting.”

The aim of the research was to encourage best practice, to which end the results will be shared with the countries whose vessels were studied.

Albatrosses, petrels and other seabirds are “irresistibly drawn” to the trailing, baited longlines, said Winnard. Each year, an estimated 100,000 birds are hooked and drowned by longline and trawl fisheries.

“This level of bycatch in the fishing industry is hugely unsustainable for birds that can take up to 10 years to start breeding,” said Winnard, who added that the findings were “truly powerful” for the way the data shed light into the “opaque world” of global fisheries and their impact on ocean biodiversity.

“No one is going to report they are not sticking to the rules or they are killing seabirds, so we now have this independent way of measuring compliance,” said Winnard. “This information has never before been public. It is usually kept behind closed doors. It will promote transparency and hold countries to account. It is the first time we’ve been able to see what is happening on individual fishing boats.”

Hawaii Tuna Fishermen Want Higher Quotas

December 4, 2018 — Hawaii’s longliners caught their quota for bigeye tuna early again this year. But that may not be an issue going forward if U.S. officials can negotiate a higher limit next week with an international fisheries commission.

Meanwhile, consumers can expect stable tuna prices for the holidays as the longline fleet continues to haul in a steady stream of fresh ahi to Honolulu’s fish auction.

The season for bigeye tuna, one of two types of fish known as ahi in Hawaii, was uninterrupted thanks in part to a quota-sharing agreement that lets the longliners fish beyond the internationally agreed upon limit for the U.S. in the Western and Central Pacific Ocean.

The Hawaii longline fleet of roughly 145 vessels, based in Honolulu, had a 2018 limit of 3,554 metric tons, which it hit Nov. 1.

But under an agreement with the Northern Mariana Islands, the longliners, as they have for the last few years, paid $250,000 into a fishery development fund and continued fishing for another 1,000 tons. The longliners were about 57 percent of the way through that extra allotment as of last week.

US Western Pacific council recommends catch limits for CNMI, presents $250K check

October 25, 2018 — The US Western Pacific Regional Fishery Management Council, at its 174th meeting in the Commonwealth of the Northern Mariana Islands (CNMI) on Monday, recommended an annual catch limit (ACL) of 228,000 pounds for all CNMI bottomfish during the 2019 fishing year. That includes such species as amberjack and red snapper.

The amount is well above the average annual catch from 2015 until 2017 of 35,696 lbs, the council noted in a press release.

The next stock assessment is scheduled for review in February 2019 and will provide new information to set the ACLs for fishing year 2020 to 2022.

The council opened its meeting by presenting a $250,000 check to CNMI governor Ralph Torres and Department of Lands and Natural Resources secretary Anthony Benavente, according to the press release. The funds, which stem from a 2017 bigeye fishing agreement between the CNMI and Hawaii longline vessels, will be used to implement a bottomfish training and fishing demonstration project, which could then lead to the purchase of a vessel to help with fishery development, council executive director Kitty Simons said.

The council also discussed, among other issues, community concerns about the pre-positioning of ships anchored off Saipan’s shores. It said it would help an advisory panel in the CNMI facilitate a meeting between the Saipan military liaison and the CNMI government.

Mandatory reporting in Hawaiian longline fishery on table at science meeting

October 16, 2018 — Mandatory electronic reporting for the Hawaii longline fishery is on the agenda when the Western Pacific Regional Fishery Management Council’s Scientific and Statistical Committee (SSC) starts its two-day meeting Monday in Hilo, Hawaii.

The SSC is also expected to discuss acceptable biological catch limits for Hawaiian gray snapper, deep-water shrimp and Kona crab as well as the management of loggerhead and leatherback sea turtle interactions in the shallow-set longline fishery.
