Saving Seafood

Preserving Poke in a Changing Climate

July 18, 2019 — The following was released by NOAA Fisheries:

Managing bigeye tuna in the Pacific is already challenging, and now a new study shows that climate change may affect our supply of this fish, used to make the deliciously popular ʻahi poke. The study projects the decline of catch in Hawai‘i’s bigeye tuna fishery as climate change continues to unfold. However, alternate scenarios could bolster ecosystem resilience and limit fishery declines.

Scientists from the Pacific Islands Fisheries Science Center, the University of Hawai‘i, and the University of Tasmania teamed up to model the ecosystem in which Hawai‘i’s bigeye tuna fishery operates. Their model projected how increasing ocean temperatures and declining plankton would affect specific fish species. (Temperature and plankton values were from a suite of climate models used by the Intergovernmental Panel on Climate Change.) The model also predicted how different scenarios, such as decreased fishing effort, could change those effects.

The scientists found that climate change led to a decline in catch regardless of whether fishing effort increased, decreased, or remained the same. A decline in bigeye tuna catch means less ‘ahi poke at your local market. However, the study also revealed fishing scenarios that may allow the ecosystem to remain resilient in the face of climate change.

“Rather than seeing the results as a doom-and-gloom future for Hawai‘i’s fishery, I see them as encouraging. They show that local choices matter, that we can decide which future scenario we want to pursue,” says lead author Phoebe Woodworth-Jefcoats. She points to two future scenarios in particular:  In one, the fishery persisted with today’s fishing effort. In another, the fishery slowly reduced its effort to half. Both scenarios showed similar declines in bigeye tuna catch, but in the second scenario, the ecosystem was resilient despite the effects of climate change, and the biomass of each fish species increased.

Training Future Leaders in Marine Science and Conservation

June 14, 2019 — The following was released by NOAA Fisheries:

The well-lit room boasts two slow cookers on a small mobile table; two deep sinks with ample counter and cabinet space; two walk-in freezers large enough to fit king-size beds; and a central, hip-high table that could easily hold multiple adult boars for roasting.

If not for the overwhelming putrid scent, the room could pass for an unfinished kitchen of a new restaurant.

“This is the worst it’ll smell,” Taylor Williams says as she loads small bones into the slow cookers, unphased by the stench that, at times, is a cross between manure and rotting animal flesh. “Well, the worst until the bones start boiling.”

This is certainly no restaurant and Williams is no master chef concocting a new and exotic (albeit smelly) culinary masterpiece in her decked-out kitchen. Rather, the marine biology college senior is an intern with the NOAA Pacific Islands Fisheries Science Center (PIFSC) and her task is to boil the meat off of turtle humerus bones in the sea turtle necropsy (animal autopsy) lab. The gruesome work is part of a project led by Williams’ mentor Shawn Murakawa to determine the age of deceased sea turtles by counting rings within the bones (similar to tree rings).

“I do all the dirty work for that project,” Williams explains, adding that the other tasks of her internship include taking care of PIFSC’s rehabilitating sea turtles, responding to after-hours sea turtle strandings, entering data, and conducting her own research project using the humeri.

Action Item Summaries
A
1. Specifying Harvest Limits for the Main Hawaiian Islands Kona Crab

The Council will consider specifying multi-year harvest limits for the main Hawaiian Island Kona crab for fishing years 2020-2023. The best scientific information available is the 2019 benchmark stock assessment with catch projection to 2026[1]. Based on this updated information, the maximum sustainable yield was estimated to be at 73,609 pounds and the overfishing limit at 33,989 pounds. The Council’s P* and SEEM* Working Groups and the Scientific and Statistical Committee (SSC) evaluated the scientific, social, ecological, economic, and management uncertainties and recommended a risk level for the Council to consider. The SEEM* working group used a new standardized process developed by the Social Science Planning Committee (SSPC), in which the social, ecological, and economic dimension is used to determine the risk of overfishing, and the monitoring and compliance/management criteria are used to determine management uncertainty. The risk of overfishing informs the Council’s consideration of annual catch limit (ACL) specification, and the management uncertainty informs the Council’s consideration in setting the annual catch target (ACT).

The Council will evaluate the following options:
1) No Action. No harvest limits will be specified for fishing year 2020-2023.
2) Specify the previous harvest limit at 3,500 pounds using the 2015 assessment (Thomas et al. 2015) for fishing year 2020-2023.
3) Specify the ACL equal to the acceptable biological catch (ABC) at P*=38 percent at 30,802 pounds and set an ACT at P*=30 percent at 28,324 pounds based on the P* and SEEM* Analysis using the 2019 benchmark stock assessment.
4) Specify the ACL equal to the ABC at P*=38 percent at 30,802 pounds and set an ACT 10 percent lower than the SEEM* analysis at P*=20 percent at 25,491 pounds using the 2019 benchmark stock assessment
5) Specify the ACL equal to the ABC at P*=38 percent at 30,802 pounds and set an ACT 20 percent lower than the SEEM* analysis at P*=10 percent at 21,243 pounds using the 2019 benchmark stock assessment

At its 178th meeting, the Council will consider taking final action to specify the harvest limits and the accountability measure that will prevent the fishery from overfishing the stock.

2. Hawai’i Fishery Ecosystem Plan Amendment to Precious Coral Essential Fish Habitat

The Council at its 173rd meeting in June 2018 directed staff to develop options to redefine essential fish habitat (EFH) and any habitat areas of particular concern (HAPC) for precious corals in Hawai’i for Council consideration for a Fishery Ecosystem Plan (FEP) amendment. EFH information was reviewed through the 2015 and 2016 annual Stock Assessment and Fishery Evaluation (SAFE) report cycles and an options paper was developed for the 174th meeting in October 2018.

New observations of precious corals have occurred throughout the region, with research concentrated in the Hawai’i Archipelago. Observations in the territories and of the larval phase of precious corals are rare or nonexistent. However, new information exists to refine the habitat characteristics and geographic extent of deep- and shallow-water precious coral EFH in the Hawai’i Archipelago. Narrative information on which the EFH designations are based and information to fulfill the EFH requirements of fishery management plans may also be used to update the archipelagic FEPs. The redefinition of precious corals EFH is framed in three separate actions: refinement of deep-water species complex EFH; refinement of shallow-water precious coral species complex EFH; and update of the narrative information.

The Council at its 174th meeting reviewed the following options for each of the three actions:
Action 1 – Update EFH for deep-water precious coral species
Options
1) No change (status quo)
2) Revise EFH by depth range
3) Refine the geographic boundary of existing precious coral beds
4) Refine the geographic boundary of existing beds and add new beds

Action 2 – Update EFH for shallow-water precious coral species:
Options
1) No change (status quo)
2) Update geographic extent and habitat characteristics.

Action 3 – Update EFH narrative information
Options
1) Update the FEP narrative information on EFH
2) Do not update the FEP narrative information on EFH

The Council took initial action at its 174th meeting directing staff to prepare an amendment to the Hawai’i FEP to revise the Precious Corals EFH and selected the following preliminary preferred options:

Action 1 – Option 4: Refine the geographic boundary of existing beds and add new beds.
Action 2 – Option 2: Update geographic extent and habitat characteristics.
Action 3 – Option 1: Update the FEP narrative information on EFH.
At its 178th meeting, the Council will consider taking final action to amend the Precious Coral EFH section of the Hawai’i FEP.

3. Managing Loggerhead and Leatherback Sea Turtle Interactions in the Hawai’i-Based Shallow-Set Longline Fishery

The Council at its 173rd meeting in June 2018 recommended amending the Pelagic FEP to establish a management framework for the Hawai’i shallow-set longline fishery that consists of 1) annual limits on the number North Pacific loggerhead and leatherback turtle interactions consistent with the anticipated level of annual interactions that is set forth in the current valid biological opinion (BiOp) and 2) individual trip interaction limits for loggerhead and leatherback turtles. The Council also recommended specifications under the framework as follows: 1) annual limits of 37 North Pacific loggerhead turtles and 21 leatherback turtles; and 2) individual trip limit of five North Pacific loggerhead turtles.

The Council’s recommendation for specifying the loggerhead and leatherback turtle annual limits was based on the anticipated level of interactions analyzed in the biological evaluation (BE) initiating reconsultation of the Hawai’i shallow-set longline fishery under the Endangered Species Act (ESA) Section 7 consultation process. As part of its recommendation, the Council noted that it would review its recommendation if the new BiOp from the ongoing consultation results in a jeopardy decision or otherwise results in a different incidental take statement for North Pacific loggerheads or leatherbacks. The new BiOp was originally scheduled to be completed by Oct. 31, 2018, but the draft was not completed in time for the October SSC and Council meeting. Following the October meetings, the National Marine Fisheries Service (NMFS) Pacific Islands Regional Office (PIRO) set a new timeline to deliver the draft BiOp by Jan. 31, 2019, and a final BiOp by Feb. 28, 2019. Due to the federal government shutdown, the draft BiOp timeline was further delayed to March 25, 2019.

At its October 2018 meeting, the SSC received a presentation from the NMFS Pacific Islands Fisheries Science Center (PIFSC) on the population viability analysis (PVA) for loggerhead and leatherback turtles prepared for the ongoing Section 7 consultation. The modeling was conducted in response to a request by the PIRO Protected Resources Division for the purpose of examining the long-term viability of the species. PVA results indicate that the North Pacific loggerhead population has a mean estimated population growth rate of 2.4 precent, while the Western Pacific leatherback turtle population has a mean estimated population growth rate of 5.3 percent. The growth rates reflect long-term population trends based on nesting beach data representing approximately 52 percent of the North Pacific loggerhead turtle population and approximately 85 percent of the Western Pacific leatherback turtle population.

The Council at its 174th meeting in October 2018 reviewed the approach to the assessment for the BiOp and considered the SSC’s report regarding the PVA. The Council recommended convening an interim Council meeting, if needed, to review draft BiOp and consider any revisions to its June 2018 recommendations based on the BiOp and stated that it will reconsider a specification of leatherback individual trip limits if necessary.

The Council convened its 175th Meeting on Dec. 17, 2018, to consider final action on additional mitigation measures for the Western Pacific leatherback turtles in advance of the draft BiOp completion, taking into consideration the results of the PVA model indicating a continuing long-term declining trend of the population. The Council deferred action until the draft BiOp and more complete information on the impacts of the fishery on the Western Pacific leatherback turtles are available to fully inform the Council decision.

The draft BiOp was provided to the Council on March 28, 2019. The Council convened its 177th meeting on April 12, 2019, to review its recommendations on the management framework from the 173rd meeting for consistency with the draft BiOp and to consider taking final action on the management framework. The draft BiOp concluded that the shallow-set longline fishery is not likely to jeopardize the continued existence of ESA-listed species, including loggerhead and leatherback turtles. However, the draft BiOp also contained Reasonable and Prudent Measures (RPMs) that were inconsistent with the Council’s recommended framework. The Council at its 177th meeting maintained its management framework recommendation from the 173rd Council meeting, additionally recommended an individual trip limit of two leatherback turtles and requested that NMFS consider revising the RPMs for consistency with the Council recommended action.

At its 178th meeting, the Council will review the final BiOp for consistency with the 177th meeting recommendations and may consider taking additional final action if any discrepancies remain with the previously recommended action.

4. US Participating Territory Longline Bigeye Catch/Allocation Limits

Bigeye tuna comprises a Pacific-wide population that is internationally managed and assessed as separate stocks in the Western and Central Pacific Ocean (WCPO) and Eastern Pacific Ocean (EPO) by the Western and Central Pacific Fisheries Commission (WCPFC) and the Inter-American Tropical Tuna Association (IATTC), respectively. The best scientific information available indicates that both stocks are not subject to overfishing nor are they overfished, according to the stock status determination reference points in the FEP for Pelagic Fisheries of the Western Pacific Region. The scientific bodies of the WCPFC and IATTC will consider new benchmark stock assessments for both stocks in 2020.

In December 2018, the WCPFC agreed on CMM 2018-01, which limits the US longline bigeye tuna catch in the WCPO to 3,554 metric tons (mt) in 2019 and 2020. CMM 2018-01 does not establish an individual limit on the amount of bigeye tuna that may be harvested annually in the Convention Area by Small Island Developing States (SIDS) and Participating Territories, including American Samoa, Guam and the Commonwealth of the Northern Mariana Islands (CNMI). Limits are not provided to the SIDS and Participating Territories in recognition of their fisheries development aspirations.

In 2014, Amendment 7 to the Council’s Pelagic FEP was approved and implemented (50 CFR 665.819). It established the territorial catch/effort and allocation limit measure that provides NMFS with authority to:
Specify annual catch or effort limits for a US Participating Territory, as recommended by the Council, not to exceed any WCPFC-adopted limits;
Specify a limit recommended by the Council authorizing a US Participating Territory to allocate a portion of that specified catch or effort limit to eligible US vessels through a specified fishing agreement; and
Review and approve specified fishing agreements for consistency with the Pelagic FEP and other applicable laws.

The Council must annually review the conservation status of the fishery resource, the needs of fishing communities dependent on the particular fishery resource and consistency with the Pelagics FEP and other applicable laws in considering its recommendations for territorial catch, effort and allocation limits as well as its review of specified fishing agreements. Amendment 7 also established a territorial longline bigeye tuna catch limit of 2,000 mt for each territory and an allocation limit of 1,000 mt for each territory. At its 173rd meeting in June 2018, the Council took final action to modify the territorial catch/effort and allocation limit measure and implementing regulations. Should NMFS approve the action, it will amend the Pelagic FEP to remove the requirement for establishing separate total catch or effort limits for the US Participating Territories in order to establish an allocation limit and also would allow multi-year limits. The Council would annually review any established limits to determine whether the best available scientific information or the needs of fishing communities warrant modifying or rescinding such limits.

At its 178th meeting, the Council will consider recommending territorial bigeye tuna catch and/or allocation limits to take effect beginning in 2020, given the Council’s recommended modification of the territorial catch, effort and allocation limit measure. The Council will consider the following options:
1. No catch or allocation limits (no action)
2. 2,000 mt catch and 1,000 mt allocation limits
3. No catch limit and up to 2,000 mt allocation limits

The Council will also consider the fishing years in which the limits will take effect or expire, in consideration of the requirement for annual review, availability of new scientific information and potential for multi-year limits.

Pacific Reef Survey Finds Sea Turtle Populations on the Rise

April 25, 2019 — Sea turtle populations in Pacific coral reefs are increasing, according to a study that reveals the positive results of environmental protection efforts around the world and gives researchers information to protect these turtles from the effects of global changes.

Researchers from the U.S. National Oceanic and Atmospheric Administration’s Pacific Islands Fisheries Science Center recorded numbers of threatened and endangered sea turtles for 13 years at 53 sites across four regions of the U.S. islands in the Pacific as part of a larger study of other marine life, according to a research article released Wednesday by PLOS ONE.

The sites were located between islands, atolls and reefs in American Samoa, the Hawaiian Archipelago, the Mariana Archipelago and the Pacific Remote Island Area complex. Each site was observed every two or three years in April, using a boat towing two scuba divers 49 feet underwater who recorded the species and numbers of turtles within sight.

Researchers observed two species specifically, the green and the hawksbill turtles. Green sea turtles greatly outnumbered hawksbill across the survey area, providing further evidence of the need to protect the endangered hawksbill.

Report: Hawaii Kona crab ample enough for increased fishing

April 2, 2019 — Hawaii’s Kona crab fishery is healthy enough to expand the catch brought to market, according to an assessment by a federal marine science agency.

The National Oceanic and Atmospheric Administration made the 2018 stock assessment of the main Hawaiian Islands Kona crab fishery, West Hawaii Today reported Monday.

Hawaii waters remain well populated with Kona crab and the crustacean is not overfished, according to the assessment published by the agency’s Pacific Islands Fisheries Science Center in Honolulu.

There is room to increase the catch without risk to the species, a related article by the agency said.

The crab fishery can sustain an annual take by harvesters of more than 73,000 pounds (33,112 kilograms), according to NOAA projections.

University researchers drew different conclusions in a 2015 assessment that said Kona crab was being overfished, the newspaper reported.

Using Artificial Intelligence to Identify Humpback Whales

November 9, 2018 — Artificial Intelligence has been used for everything from teaching computers to play chess to helping speed ride-sharing services on their way. And now one government agency is using it to track humpback whales in the Pacific.

For more than a decade, the National Oceanic and Atmospheric Administration has been tracking whales by recording them.

But there are challenges – like the sheer volume of data. Researchers have to sift through years of audio. Literally. Years.

“So far we’ve collected over 170,000 hours of data. Let’s put that in real terms. If you were to sit and listen straight, not sleeping, not eating, taking no breaks, it would take you 19 years to listen to all that data,”  says Ann Allen, a research oceanographer with NOAA’s Cetacean Research Program at the Pacific Islands Fisheries Science Center.

Fishery Managers Agree on Catch Limits for US Pacific Territories Bottomfish, Bigeye Tuna

October 23, 2015 — UTULEI, American Samoa — The following was released by the Western Pacific Regional Fishery Management Council:

The bottomfish annual catch limits (ACLs) in American Samoa, Guam and the Commonwealth of the Northern Mariana Islands (CNMI) should be equal to their acceptable biological catch (ABC), the Council deemed yesterday as it concluded its two-day meeting in Utulei, American Samoa. The ABCs are set by the Council’s Scientific and Statistical Committee and refer to the amount of fish that can be harvested without causing overfishing. The amounts are 106,000 pounds for American Samoa; 66,000 pounds for Guam; and 228,000 pounds for CNMI. In making its decision, the Council determined that the difference between recent harvest levels and ACLs in all three island areas were sufficient to ensure the ACLs will not be exceeded.

The Council yesterday also approved the proposed management policy, goals and objectives for the American Samoa, Hawaii, Mariana, Pelagic and Pacific Remote Islands Area Fishery Ecosystem Plans (FEPs), which are undergoing a five-year review. The proposed policy is to apply responsible and proactive management practices, based on sound scientific data and analysis and inclusive of fishing community members, to conserve and manage fisheries and their associated ecosystems. The proposed goals are to 1) Conserve and manage target and non- target stocks; 2) Protect species and habitats of special concern; 3) Understand and account for important ecosystem parameters and their linkages; and 4) Meet the needs of fishermen, their families and communities. The National Marine Fisheries Service will review the draft plans to provide comprehensive agency feedback, input and guidance by mid December.

Certificates and plaques of recognition were awarded to 40 seafood vendors who are helping local and federal fishery managers better understand American Samoa’s commercial fishery. Pictured (from left) are Council Chair Ed Ebisui Jr., American Samoa DMWR Director Ruth Matagi-Tofiga, Aukuso Gabriel of Josie’s Restaurant, Charles Nelson of Equator Restaurant, Hana of P n F Mart, Council Executive Director Kitty Simonds, Tom Drabble of Sadie’s Hotels, and Michelle Shaosxia Ma and Tua Agalelei of Sunny’s Restaurant

During its two-day meeting in America Samoa, the Council also maintained its recommendation made in June to specify the 2016 US longline bigeye tuna limits for the three US Pacific Territories at 2,000 metric tons (mt) each. Up to 1,000 mt per territory would be authorized to be allocated to US fishermen through specified fishing agreements authorized under Amendment 7 of the Pelagic FEP. The Council recognized that these limits are consistent with the conservation and management framework of the Western and Central Pacific Fisheries Commission and are not impeding international conservation objectives to eliminate bigeye overfishing.

Recommendations by the Council that are regulatory are transmitted to the Secretary of Commerce for final approval.

The Council also directed staff to request that the Department of Justice consider directing funds received from fines and penalties from marine pollution violations that occur in waters of the Territory of American Samoa or in the US exclusive economic zone waters around American Samoa be provided to the American Samoa government. The funds would be used to support conservation and management activities identified in the America Samoa’s Marine Conservation Plan.

The Council officers for 2016 were selected and will remain the same as this year, with Edwin Ebisui Jr. of Hawaii as chair and Michael Duenas (Guam), John Gourley (CNMI), McGrew Rice (Hawaii) and William Sword (American Samoa) as vice chairs.

The Council also appointed Mike Tenorio to the Scientific and Statistic Committee; Peter Crispin to the Pelagic Fisheries Sub-Panel and Nonu Tuisamoa to the Ecosystem and Habitat Sub-Panel of the American Samoa Advisory Panel; Daniel Roudebush to the Ecosystem and Habitat Sub-Panel and Geoff Walker to the Pelagic Fisheries Sub Panel of the Hawaii Advisory Panel; and Archie Taotasi Soliai, StarKist manager, to the Fishing Industry Advisory Committee.

The Council provided certificates of recognition to 40 seafood vendors who provided their monthly receipts of fish sales to help improve understanding of American Samoa’s commercial fishery. Vendors who submitted 100 percent of their receipts each month for the past year received special plaques of recognition. The project is a partnership involving the Council, NMFS Pacific Islands Fisheries Science Center and the American Samoa Department of Marine and Wildlife Resources.

For more on the meeting, go to www.wpcouncil.org, email info@wpcouncil.org or phone (808) 522-8220. The Council was established by Congress under the Magnuson-Stevens Fishery Conservation and Management Act in 1976 to manage domestic fisheries operating seaward of State waters around Hawai`i, American Samoa, Guam, the CNMI and the US Pacific Island Remote Island Areas.

At Sea, Merely Observing Can Be Risky Business

October 20, 2015 — It was a month into the voyage from Spain to the Ross Sea in Antartica that the captain of the fishing boat threatened to throw Liz Mitchell overboard.

In the frigid waters of the Southern Ocean, off the Falkland Islands, that would have meant certain death.

But all that Mitchell, a U.S. fisheries observer, could think of was how embarrassed she was. The captain had just screamed at her in front of his officers, because she witnessed his crew transferring fishing bait to another vessel in mid-sea.

“When that guy said that to me I was shaking, but only because I was humiliated,” Mitchell said. “At the time I didn’t take him seriously, that he could actually do that. I don’t know whether it was naiveté or just plain being stupid, but I just never believed anybody would do that to me.”

Fisheries observers face the same treacherous conditions as commercial fishermen: the risk of getting a hand caught in a winch, being knocked overboard by a rogue wave, of dying in a capsized vessel. But observers face special risks of their own — from those they watch.

It was part of Mitchell’s job to record and report conduct such as the bait transfer — a possible flag for an unregistered boat fishing illegally. She had been hired on to monitor the vessel’s movements as well as track commercial fish and protected species it caught or killed along the way.

Not long before, Mitchell had been told by a crew member that the ship she was on — a U.S.-flagged longliner — had ties to a notorious Spanish fish poacher. That made the threat of being thrown into the sea all the more salient.

Threats and intimidation are an unfortunate part of the job, said Mitchell, who is president of the Association for Professional Observers, a nonprofit that advocates for better living conditions and improved safety measures. She got her start as a fisheries observer in Alaska in 1983, and did stints all over the world, including in Hawaii. She now lives in Oregon.
