Scientists Support Combined Management Measures for Uku, Review Mitigation Tactics for False Killer Whales

June 16, 2021 — The following was released by the Western Pacific Regional Fishery Management Council:

The Scientific and Statistical Committee (SSC) of the Western Pacific Regional Fishery Management Council supported the combined management of the commercial and noncommercial sectors of the main Hawaiian Islands (MHI) uku fishery. Commercial fishery data is submitted mandatorily through monthly reports. However, variabilities in the noncommercial data from the voluntary Hawai‘i Marine Recreational Fisheries Survey (estimated bi-monthly) raise uncertainties about the reliability of this system as a tool for in-season tracking against the annual catch limit. Improvements in data collection systems and establishing a proper management framework for sector allocation are required if the uku fishery is to be managed separately.

In September 2020, the SSC set the acceptable biological catch for uku at 297,624 pounds for fishing years 2022 to 2025. The MHI stock is not overfished or subject to overfishing.

The Committee noted that the decision whether to use sector allocation of the total annual catch target is purely a management action. A 2020 stock assessment from the Pacific Island Fisheries Science Center indicates that noncommercial fishers harvest smaller fish compared to commercial fishers due to fishing location and gear type differences. From a scientific standpoint, this justifies managing the uku fishery separately. The SSC chair suggested that the group conduct a risk analysis to determine if management measures should be different for the two sectors in the future.

A working group of the SSC highlighted their preliminary findings on alternative approaches to reduce impacts to false killer whales (FKWs) in the Hawai‘i deep-set longline fishery. The draft issues paper reviews the history of the Pacific Islands Region FKW Take Reduction Team and their recommendations, past SSC recommendations, cetacean avoidance research and interaction reduction measures, among other topics.

The group suggested, for example, that mitigation strategies should focus on removing the trailing gear from an accidentally hooked FKW instead of using weak circle hooks, which to date have proved ineffective. Also, they noted there is not enough demographic information, such as survival rates at different ages and reproductive rates, to do a population assessment or diagnose trends for FKWs. The working group will work with the full Committee to review the findings and associated recommendations.

The meeting continues through Thursday, June 17, 2021. Instructions on connecting to the web conference, agenda and briefing documents are posted at www.wpcouncil.org/event/140th-scientific-and-statistical-committee-virtual-meeting.

Pacific Scientists to Consider Snapper Catch Limits, Evaluate Gear Requirements in Longline Fisheries

June 11, 2021 — The following was released by the Western Pacific Regional Fishery Management Council:

Scientists from throughout the Pacific will meet June 15 to 17, 2021, to provide advice on managing the main Hawaiian Islands (MHI) uku fishery, longline fishery gear and release requirements, and other topics to the Western Pacific Regional Fishery Management Council. The meeting of the Scientific and Statistical Committee (SSC) will be held virtually and is open to the public. The full agenda, background documents and instructions for connecting to the meeting and providing oral public comments are available at www.wpcouncil.org/event/140th-scientific-and-statistical-committee-virtual-meeting. Among the agenda items are the following:

MHI Uku Catch Limits
At its September 2020 meeting, the SSC set the acceptable biological catch for uku (green/gray jobfish) at 297,624 pounds for fishing year 2022 to 2025. This corresponds to a 43% risk of overfishing when accounting for scientific uncertainties. The SSC may provide scientific advice on the appropriate level of management based on the ability to track the catch in-season. The commercial fishery data is from monthly mandatory fisher reports, while the noncommercial fishery data is estimated from voluntary surveys completed every two months. The SSC will consider if the uku fishery commercial and noncommercial sectors should be managed as a whole or separately.

Gear and Release Requirements for Longline Fisheries
Most vessels in the Hawai‘i deep-set longline fishery use wire leaders in the terminal portion of the branchline between the hook and the weighted swivel to reduce the risk of crew injuries resulting from flyback. Wire leaders make it difficult to remove the terminal portion of the branch line from sharks or other protected species that cannot be brought onboard. Switching to monofilament nylon leaders would allow crew to remove gear closer to the hook and may facilitate a shark’s ability to break free by biting through the line. Tagging studies show that shorter trailing gear gives sharks a better chance of survival.

The Hawaii Longline Association announced at the December 2020 Council meeting that their member vessels will voluntarily eliminate the use of wire leaders by July 1, 2021, and use monofilament nylon leaders or other similar materials. The Council is considering a regulatory change to prohibit the use of wire leaders and to require removal of trailing gear to improve post-hooking survivorship of Endangered Species Act-listed oceanic whitetip sharks and other protected species. The SSC will discuss results from a risk analysis tool that the Pacific Islands Fisheries Science Center (PIFSC) applied to several longline mitigation measures, including the transition to monofilament leaders, among others. The tool provides all possible outcomes of decisions taken and assesses the impact of risk, which allows managers to make better decisions under uncertainty. The SSC may provide additional scientific input to the Council to inform its decisions on the transition from wire leaders and removal of trailing gear.

Recommendations made by the SSC on these and other matters will be considered by the Council when it meets June 22-24, 2021, virtually with host sites at Tedi of Samoa Building, Suite 208B, Fagatogo Village, American Samoa; BRI Building, Suite 205, Kopa Di Oru St., Garapan, Saipan, Commonwealth of the Northern Mariana Islands (CNMI); and Cliff Pointe, 304 W. O’Brien Dr., Hagatña, Guam. Instructions on connecting to the web conference, agendas and briefing documents are posted at www.wpcouncil.org/meetings-calendars.

More Measures Proposed for Western Pacific Longliners as Managers Agree to Electronic Reporting

September 22, 2020 — The Western Pacific Regional Fishery Management Council concluded its 2020 third-quarter meeting recently with actions related to electronic reporting for Hawaii longline fisheries, annual catch limits for grey snapper (uku) for years 2022-2025 and more.

Hawaii longliners and those greater than 50 feet long in the American Samoa longline fleet will have to use electronic logbook reporting by the middle of next year, the Council approved in an amendment to the fishery management plan. Under the amendment, vessel operators must record and submit logbook data within 24 hours after completion of each fishing day using an electronic logbook application certified by the National Marine Fisheries Service. In the event of technology malfunction, vessel operators would be required to submit the logbook data by paper or electronically within 72 hours of the end of each fishing trip. The recommended date for implementing mandatory electronic reporting is by July 1, 2021; the regulatory amendment is pending approval by the Secretary of Commerce.

WPRFMC: Federal Fishery Managers Agree to Longline Electronic Reporting, Preliminary Hawai’i Grey Snapper Limits

September 21, 2020 — The following was released by the Western Pacific Regional Fishery Management Council:

Yesterday, the Western Pacific Regional Fishery Management Council concluded its 2020 third-quarter meeting with the following recommendations and actions, among others. The Council is mandated by Congress to manage the fisheries offshore of Hawai’i, American Samoa, Guam, the Commonwealth of the Northern Mariana Islands (CNMI) and the U.S. Pacific Remote Islands Areas. The complete list of actions taken by the Council at the three-day meeting will be posted at http://www.wpcouncil.org/event/183rd-council-meeting/.

Mandatory Electronic Reporting: The Council took final action on a regulatory amendment for mandatory electronic reporting for vessels operating under the Hawai’i longline limited entry permit and vessels larger than 50 feet in length (i.e., size classes C and D) operating under the American Samoa longline limited entry permit. Under the amendment, vessel operators must record and submit logbook data within 24 hours after completion of each fishing day using an electronic logbook application certified by the National Marine Fisheries Service (NMFS). In the event of technology malfunction, vessel operators would be required to submit the logbook data by paper or electronically within 72 hours of the end of each fishing trip. The recommended date for implementing mandatory electronic reporting is by July 1, 2021. This regulatory amendment is pending approval by the Secretary of Commerce.

Main Hawaiian Island Grey Snapper (Uku): The Council selected a preliminary annual catch limit (ACL) of 295,419 for main Hawaiian Islands (MHI) grey snapper for fishing years 2022 to 2025. This ACL corresponds to a 41% risk of overfishing. The Council also selected an annual catch target (ACT) at 36% risk of overfishing, which corresponds to annual catch of 291,010 pounds. The Council will work with the National Marine Fisheries Service (NMFS) to develop accountability measures to ensure the catch does not exceed the ACL. The Council recommended that accountability measure options be considered that recognize the challenges with tracking catch from the noncommercial fishery. The Council may take final action on the ACL and accountability measures at its meeting in March 2021.

Seabird Mitigation in the Hawai’i Longline Fishery: Hawai’i longline vessels are required to mitigate interactions with seabirds. The Council will be considering including tori lines (also known as bird streamers or bird scare lines) at a future meeting as an additional option to measures already in place. The Council asked NMFS to support at-sea trials for winter 2020/spring 2021 through an Experimental Fishing Permit that would allow testing tori line efficacy without the use of blue-dyed bait when fishing north of 23° N.

North Pacific Striped Marlin: The Council will work with NMFS Pacific Islands Regional Office (PIRO) to develop a proposed international measure to limit total catch of North Pacific striped marlin in the Western and Central Pacific Ocean from 2021 to 2024. The North Pacific population is considered to be overfished and subject to overfishing. The Council will work with NMFS PIRO to incorporate U.S. longline catch limits of North Pacific striped marlin at 457 metric tons, consistent with previous Council recommendations, into the proposed measure.

Oceanic Whitetip Sharks: The Council requested NMFS PIFSC to provide updates on its oceanic whitetip shark projects for the Council and Scientific and Statistical Committee (SSC) to consider at its December 2020 meetings. The species is considered overfished and subject to overfishing and is listed as threatened under the Endangered Species Act. The Council also recommended that the Oceanic Whitetip Shark Working Group proceed with analyzing longline mitigation measures and that updates be completed and reviewed by the Council’s Plan Team before the March 2021 SSC meeting.

Advisory Committees: The Council approved the membership of the Non-Commercial Fishing Advisory Committee to include the Hawai’i Marine Recreational Fishing Survey coordinator, NMFS PIRO recreational fishing coordinator,NMFS PIFSC recreational fishing coordinator,Saipan Fishermen’s Association representative,Pago Pago Gamefish Association Representative, Shut Up and Fish (Guam noncommercial), Hawaii Fishermen’s Alliance for Conservation and Tradition representative(s), Pacific Islands Fisheries Group representative(s) and Hawai’i fishing club representative(s).

The Council also approved the following proposed new members of the Fishing Industry Advisory Committee: Michael Goto (United Fishing Agency, Ltd., Hawai’i), Kerry Umamoto (Hilo Fish Company, Hawai’i), Josh Schade (Ahi Assassins, Hawai’i), Eric Kingma (Hawaii Longline Association, Hawai’i), Kenton Geer (commercial seamount fisherman, Hawai’i),Carlos Herrera (Hitman’s Tackle, Guam), Vince Haleck (Tautai O Samoa Association, American Samoa), Lino Tenorio (commercial bottomfish fisherman, Commonwealth of the Northern Mariana Islands) and Dean Sensui (Hawaii Goes Fishing, Western Pacific Region).

Offshore Energy: The Council adopted an offshore energy policy that takes into account potential impacts of such developments to federal fisheries, habitat and ecosystem.

Scientists to Set Acceptable Biological Catch for Main Hawaiian Islands Uku and Consider Hawaii Small-Boat Fisheries Management Options

September 3, 2020 — The following was released by the Western Pacific Regional Fishery Management Council:

Scientists from throughout the Pacific will convene Sept. 9-10, 2020, to discuss fishery management issues and make management recommendations for fisheries in the Western Pacific Region. The meeting of the Scientific and Statistical Committee (SSC) of the Western Pacific Regional Fishery Management Council will be held virtually and is open to the public. The full agenda, background documents and instructions for connecting to the meeting and providing oral public comments are available at www.wpcouncil.org/event/137th-scientific-and-statistical-committee-meeting. Among the agenda items are the following:

Main Hawaiian Islands Uku

The SSC will set the acceptable biological catch for the main Hawaiian Islands uku (grey snapper) fishery for fishing years 2022-2025. The best scientific information available for fishery management decisions is the 2020 stock assessment with catch projections to 2026. Based on this information, the maximum sustainable yield is estimated to be 204,972 pounds and the overfishing limit is 301,948 pounds. A panel of fishermen, fishery scientists and managers evaluated the social, ecological, economic and management uncertainties associated with the assessment and quantified a risk level for the SSC to consider.

Hawaiʻi Small-Boat Fisheries

Information on Hawaiʻi small-boat fisheries, which does not include the Hawaiʻi longline vessels, is currently insufficient for robust fisheries management. The Council will consider options that include no action, variations on a mandatory permitting and reporting system (including by sector or by species), a registry system and a pilot permit system. The Council held a virtual Fishers Forum and public meeting to discuss these options Aug. 27, 2020. The SSC will hear a report about the public meeting and an analysis of the options and may choose to recommend one for Council consideration.

Oceanic Whitetip Sharks

The SSC will hear a report on population projections for the western and central Pacific Ocean (WCPO) stock of oceanic whitetip sharks, a species that was overfished per a 2019 assessment and listed under the Endangered Species Act. Population projections for the stock assess the impact of internationally implemented conservation and management measures since 2013 (which prohibit shark retention and ban the use of “shark lines”) and are based on expected catches throughout the Pacific. The projections use updated estimates of post-release mortality. The SSC may make recommendations on the projections and report.

North Pacific Striped Marlin

Following a Council recommendation on phased catch reductions for striped marlin, the SSC will also review and may make recommendations on a rebuilding plan for North Pacific striped marlin and allocations of international catch limits. The stock has been internationally overfished per a 2019 stock assessment. The Council is required to address relative impacts of domestic fisheries and international overfishing per the Magnuson-Stevens Fishery Conservation and Management Act. Approximately 6% of reported North Pacific striped marlin landings since 1975 is attributed to U.S. Pacific fisheries, including the Hawaiʻi longline fishery.

Recommendations made by the SSC on these and other matters will be considered by the Council when it meets Sept. 14-17, 2020, virtually with host sites at Cliff Pointe, 304 W. O’Brien Dr., Hagatna, Guam; Hyatt Regency Saipan, Royal Palm Ave., Micro Beach Rd., Saipan, Commonwealth of the Northern Mariana Islands (CNMI); and Department of Port Administration, Airport Conference Room, Pago Pago International Airport, Tafuna Village, American Samoa. Instructions on connecting to the web conference, agendas and briefing documents will be posted at www.wpcouncil.org/meetings-calendars. Host sites are subject to local and federal safety and health guidelines regarding COVID-19; check the Council website for updates.

Feds Advance Management of Main Hawaiian Islands Uku, Rebuilding Plan for American Samoa Bottomfish

June 26, 2020 — The following was released by the Western Pacific Regional Fishery Management Council:

During the months of May through July, Hawai’i fishermen and seafood consumers can rely on uku (grey snapper). While available year-round, this flavorful pink to white flesh fish, is most abundant during this time, which is when it spawns. These months also coincide with the period between the peak of the winter season for deep-water snappers and before the summer run of ‘ahi (yellowfin tuna). A versatile species, uku can be found in a wide range of depths and can be caught by trolling, bottomfishing and even spearfishing.

Yesterday, during the second day of its three-day virtual meeting, the Western Pacific Regional Fishery Management Council reviewed a new stock assessment for the main Hawaiian Island uku prepared by the National Marine Fisheries Service (NMFS). Established by Congress in 1976, the Council develops management plans and amendments and monitors federal fisheries operating in waters offshore of the State of Hawai’i, the Territories of American Samoa and Guam, the Commonwealth of the Northern Mariana Islands (CNMI) and the US Pacific Remote Islands Areas.

The Council directed staff to assess the scientific and management uncertainties in the fishery so that it could recommend the annual catch limit (ACL) for the fishery, when it meets next, in September. The Council will also explore splitting allocation of the ACL between the noncommercial and commercial fishing sectors. The Council’s recommendation will then go to the Secretary of Commerce for final approval.

Another major topic on the agenda yesterday was development of a rebuilding plan for American Samoa bottomfish. The most recent NMFS stock assessment for the fishery indicates that the fishery is overfished (too many fish have been removed) and subject to overfishing (too much fishing effort is occurring). Fishermen and the American Samoa Department of Marine and Wildlife Resources (DMWR) believe that the pessimistic assessment is due to poor and incomplete data.

Bottomfish habitat maps suggest that the majority of the bottomfish are caught in waters 0 to 3 miles from shore, which are under the Territory’s jurisdiction. The proposed interim measure would allow only 13,000 pounds of bottomfish to be caught annually from both federal and territorial waters, after which the bottomfish fishery in federal waters would be shut down. The average annual catch from 2013 to 2017 has been 21,139 pounds.

The Council will work with its Scientific and Statistical Committee and the American Samoa DMWR to explore other management options, such as area management and including cultural harvest at the offshore banks for deep-water snappers, to address the overfished status. The Council also requested that the NMFS Pacific Islands Fisheries Science Center (PIFSC) prioritize the development of a fishery-independent survey in American Samoa to improve understanding of the stock.

To help improve the collection of data in the American Samoa bottomfish fishery, the Council directed its staff to work with its local fishermen advisors in the Territory to identify ways the members can assist with training fishermen on using a self-reporting data app. The Council also requested that the American Samoa DMWR work with the Governor’s Fisheries Task Force to address issues with data collection that have led to the current poor stock status and to coordinate with the Council and NMFS PIFSC to develop a strategy to address those issues.

The Council also directed its staff to explore the creation of sectors in the American Samoa bottomfish fishery that would separate the species complex between the nearshore bottomfish fishery and the offshore deep-water snapper fishery.

The Council meeting will conclude today, by web conference (Webex) with host sites at the Hilton Guam Resort & Spa, Chuchuko Room, 202 Hilton Rd., Tumon Bay, Guam; Hyatt Regency Saipan, Royal Palm Ave., Micro Beach Rd., Saipan, CNMI; and Department of Port Administration, Airport Conference Room, Pago Pago International Airport, Tafuna Village, American Samoa. Instructions on connecting to Webex, agendas and briefing documents will be posted at www.wpcouncil.org/meetings-calendars.

Scientists Recommend Setting Annual Catch Limits for Uku in Main Hawaiian Islands, Options for American Samoa Bottomfish Management and Protected Species Mitigation Measures

June 15, 2020 — The following was released by the Western Pacific Regional Fishery Management Council:

The Scientific and Statistical Committee (SSC) of the Western Pacific Regional Fishery Management Council concluded its three-day virtual meeting yesterday. Key outcomes addressed the main Hawaiian Islands uku stock assessment, American Samoa bottomfish rebuilding plan and measures to mitigate incidental interactions of the Hawai’i and American Samoa longline fisheries with protected species.

Recommendations made by the SSC on these and other matters will be considered by the Council when it meets June 23-25, 2020, by web conference (Webex) with host sites at the Hilton Guam Resort & Spa, Chuchuko Room, 202 Hilton Rd., Tumon Bay, Guam; Hyatt Regency Saipan, Royal Palm Ave., Micro Beach Rd., Saipan, CNMI; and Department of Port Administration, Airport Conference Room, Pago Pago International Airport, Tafuna Village, American Samoa. Instructions on connecting to Webex, agendas and briefing documents will be posted at www.wpcouncil.org/meetings-calendars.

Main Hawaiian Islands Uku Stock Assessment

The uku (Aprion virescens; grey snapper) stock in the main Hawaiian Islands (MHI) is not overfished nor subject to overfishing according to a NOAA Pacific Islands Fisheries Science Center (PIFSC) 2020 assessment presented at the SSC meeting. The uku fishery is considered to be data-rich, using a fishery-independent measure of biomass, length and local life history information gathered from the commercial and non-commercial sectors. The 2018 spawning stock was estimated to be 1.8 million pounds, which is 2¾ times the calculated sustainable threshold of 663,705 pounds. The SSC accepted the assessment as the best scientific information available and recommended that the Council direct staff to convene the P* and Social Economic Ecological and Management Uncertainties working groups. The analyses from these groups quantify uncertainties and set the acceptable biological catch and specify the annual catch limits for the main Hawaiian Islands uku fishery for fishing years 2021-2024.

American Samoa Bottomfish Rebuilding Plan

In contrast to the data-rich MHI uku fishery, the American Samoa bottomfish fishery is data-poor. This data-limited situation has persisted for decades and culminated with a 2019 stock assessment that said the American Samoa bottomfish stock was overfished and subject to overfishing. National Marine Fishery Service (NMFS) notified the Council of its obligation to end overfishing immediately and develop and implement within two years a plan that would rebuild the overfished stock within 10 years. This fishery harvests multiple species of varying depth range and has diverse life history characteristics for which information is sparse and borrowed from other areas. Data sources are only from creel surveys that estimate total catch and the commercial receipt book system that captures fish sold to the market.

The SSC deliberated the different scenarios to reduce overfishing and rebuild the stock. The very low catch projections from the assessment do not allow for a viable fishery with a catch limit projected to be 2,000 pounds and in order to rebuild within 10 years, the catch has to be further reduced to 1,500 pounds. The SSC recommended that the Council work with American Samoa to develop management options and explore effort and biological limits and area management.

The SSC also discussed the cultural significance of the bottomfish fishery and recommended that the bottomfish rebuilding plan include cultural harvest in the offshore banks for deep-water snappers. American Samoa is a Magnuson-Stevens Act-designated fishing community that is widely recognized as having a unique ability to adapt to technological change while maintaining strong cultural resilience, roots and identity through the practice of Samoan custom and the Samoan way known as fa’a Samoa.

The SSC emphasized that closing the fishery means that no new information is generated that can be used in the next stock assessment. With the COVID-19 pandemic, data collection efforts have been reduced with unknown consequences on the quality of data that will represent fishing year 2020.

Reasonable and Prudent Measures for Protected Species Interactions

The SSC reviewed considerations to mitigate incidental interactions with protected species that may be needed under the ongoing Endangered Species Act consultations for the Hawai’i deep-set and American Samoa longline fisheries.

The SSC found that interactions with protected species such as leatherback turtles and giant manta rays are rare. Based on available scientific information, including recent sea turtle population assessments, the relative impact to these species from US longline fisheries operating out of Hawai’i and American Samoa is low compared to foreign fisheries. Any measure implemented in these fisheries is likely to have a limited effect on the population. The SSC recommended that mitigation measures create incentives for industry to report and reduce impacts. Measures should also consider trade-offs of target catch and protected species interactions to avoid unintended consequences.

Data from US longline fleets, highlighted by the SSC for its conservation value, represent one of few reliable sources for the overall number of interactions with protected species. Hawai’i-based deep-set longline fishery targeting bigeye tuna and American Samoa longline fishery targeting albacore are monitored with 20% federal observer coverage. In contrast, most international fleets operating in the North Pacific Ocean have less than 5% coverage.
