Using Sound as a Tool to Help Count Snappers in Hawai‘i and Prevent Overfishing

April 30, 2021 — The following was released by NOAA Fisheries:

Snappers are economically important species for fisheries worldwide. To determine the health of snapper populations, we must monitor their abundance and record any changes in their biomass. NOAA scientists conducted a study to test new, more efficient and accurate methods to regularly monitor snapper in the Hawaii bottomfish fishing grounds. The results of this study were recently published in the ICES Journal of Marine Science.

Snappers are abundant in nearshore, 100–400-meter deep subtropical and tropical oceans with rocky, uneven bottoms that have steep slopes. They typically occupy areas near the ocean floor but are also found further in the water column and within crevices or under outcrops.

Modern research methods limit accurate and efficient abundance estimations for these species. Trawl sampling is not feasible as the highly uneven, rocky bottom would damage the net and the fragile habitat itself could be disturbed. More recent underwater video observations are limited by light and field-of-view distance. Placing video cameras in the water can also scare away or attract fish, skewing the results.

Citizen Scientists Help Reveal Undetected Hawaiian Monk Seal Reproduction

April 26, 2021 — The following was released by NOAA Fisheries:

A group of NOAA scientists has published a new paper in Marine Mammal Science that improves their estimations of reproductive rates in Hawaiian monk seals. Sighting patterns reveal unobserved pupping events, which revises reproductive rate estimates for Hawaiian monk seals in the main Hawaiian Islands. They couldn’t have done it without the help of citizen scientists reporting monk seal sightings. NOAA relies on public reports to collect data on seals in the main Hawaiian Islands. It would be impossible to consistently survey all of the beaches along 750 miles of inhabited shoreline.

Hawaiian monk seals are among the world’s most endangered marine mammals, with only around 1,400 remaining. Most of the population (about 1,100 seals) inhabit the remote Northwestern Hawaiian Islands. The remainder (about 300 seals) live in the heavily populated main Hawaiian Islands. The monk seal has recently shown positive population trends in these islands. At the core of these encouraging data is the number of pups born each year.

Counting Pups

Hawaiian monk seals have pups throughout the year. NOAA sends teams of biologists to the Papahānaumokuākeakea Marine National Monument every year to count the monk seal population. And while the main Hawaiian Islands are densely populated with humans, monk seals often select secluded beaches for pupping. This makes it hard to know when and where to look, so it’s easy to miss some. And since we don’t always witness their birth, we don’t see or identify many of those seals until they are adults. That makes it difficult to estimate their age when they have pups of their own.

If we can improve how we measure maternal age and pup production, we can improve our estimate of the population’s reproductive rates. That enhances our ability to track population trends.

Citizen Scientists Make it Possible

Unlike our work conducted from remote camps in the Northwestern Hawaiian Islands, it is not possible to routinely survey all beaches along more than 700 miles of coastline in the inhabited (main) Hawaiian Islands. NOAA relies on public reports and volunteer citizen scientists to collect data on seals in the main Hawaiian Islands. Public reports and the contribution of volunteer citizen scientists allow our researchers to record many more pupping events on the main Hawaiian Islands. Our researchers were able to use these data in their study.

Public participation in monk seal monitoring vastly extends the coverage that agency biologists can accomplish alone. It also engages the community in stewardship of natural resources in Hawaiʻi. For example, with so many things shut down in 2020, NOAA biologists weren’t able to survey monk seals in the Northwestern Hawaiian Islands. However, our information flow in the main Hawaiian Islands remained strong thanks to citizen scientists.

You can add to our data set by reporting your own monk seals sightings to the state-wide hotline at (888) 256-9840! Keep in mind, there is no need to approach a monk seal to make a report—always keep a safe distance from wildlife.

Thanks to these efforts, the newly published research describes the reproductive cycle and estimates reproductive rates of female Hawaiian monk seals in the main Hawaiian Islands.

Expedition hauls tons of plastic out of remote Hawaii atolls

April 23, 2021 — A crew returned from the northernmost islands in the Hawaiian archipelago this week with a boatload of marine plastic and abandoned fishing nets that threaten to entangle endangered Hawaiian monk seals and other animals on the uninhabited beaches stretching more than 1,300 miles north of Honolulu.

The cleanup effort in Papahanaumokuakea Marine National Monument lasted three weeks and the crew picked up more than 47 tons (43 metric tons) of “ghost nets” and other marine plastics such as buoys, crates, bottle caps and cigarette lighters from the shores of the Northwestern Hawaiian Islands.

The monument, the largest protected marine reserve in the U.S. and one of the largest in the world, is in the northern Pacific Ocean and surrounded by what is known as the Great Pacific Garbage Patch — a huge gyre of floating plastic and other debris that circulates in ocean currents. The islands act like a comb that gather debris on its otherwise pristine beaches.

The ecosystem in the monument is diverse, unique and one of the most intact marine habitats on Earth. But the beaches are littered with plastic and nets that ensnare endangered Hawaiian monk seals — of which there are only about 1,400 left in the world — and green turtles, among other wildlife.

The crew removed line from a monk seal on the expedition’s first day.

With virtually no predators, the islands are a haven for many species of seabirds, and Midway Atoll is home to the largest colony of albatross in the world. There, the land is littered with carcasses of birds that have ingested plastics and died.

The cleanup was organized by the nonprofit Papahanaumokuakea Marine Debris Project, which partners with the state of Hawaii and federal agencies, including the National Oceanic and Atmospheric Administration and the U.S. Fish and Wildlife Service.

American Samoa loses fishing rights decision in Ninth Circuit

April 2, 2021 — The American Samoa government was dealt a setback Friday last week when the Ninth Circuit Court reversed a decision that blocks large fishing vessels from fishing in a zone around their territory.

In 2016, the government of American Samoa claimed in a federal lawsuit the United States shrank a prohibited fishing zone around the South Pacific territory that was meant specifically for local fishers. The zone changed from 50 nautical miles to 12.

Boats larger than 50 feet were blocked from fishing and meant to avoid gear conflicts and competition between large fishing operations and local vessels.

American Samoa, through its status as an unorganized sovereign territory, is allowed a special right to maintain its traditions, culture and control of its lands and waters under a treaty signed in 1900 between several island chiefs and the U.S government.

But in 2016, the U.S. government said there was only one small vessel in the territory that was fishing in the waters — something the American Samoa government denied in its federal complaint filed in the District of Hawaii.

U.S. Pacific Fishery Managers Support Changes to Address Overfishing for Striped Marlin

March 26, 2021 — The following was released by the Western Pacific Regional Fishery Management Council:

To address the relative impacts of U.S. vessels on the internationally overfished North Pacific striped marlin, the Western Pacific Regional Fishery Management Council recommended an initial catch limit of approximately 1 million pounds (457 metric tons) in 2022. This applies to all U.S. vessels fishing north of the equator and west of 150 °W. An in-season accountability measure would also be implemented to track catch relative to the limit. Retention and landing of striped marlin would be prohibited in longline fisheries when the catch limit is projected to be reached.

Due to highly uncertain historical foreign catch and discards, the Council noted the U.S. relative impacts are unclear. This uncertainty in part will likely be reconciled in 2022 with new analyses by an international science provider. Beginning in 2023, the Council recommended a catch limit corresponding to a proportional fishery-wide reduction to end overfishing. Based on the current best scientific information available, the limit would be 690,000 pounds (313 metric tons), which the Council will specify for 2023.

U.S. Pacific fisheries, including the Hawai‘i longline fishery, landed approximately 19% of reported striped marlin catch from 2013 to 2017, including discards that only the United States reports. “The Hawai‘i fishery has a relatively small impact on the striped marlin stock,” said Council member Roger Dang, owner of longline vessels and Fresh Island Fish of Hawai‘i. “We must remain humble in what we can do and not exhaust our resources without having any real conservation benefit.”

The Council’s international recommendations to move towards ending overfishing include using circle hooks and improving standardized reporting of billfish catch and discards in all Western and Central Pacific Ocean longline fisheries. Recognizing that the United States acting alone would not end overfishing, the Council also recommended limiting Western and Central Pacific Fisheries Commission member catches to approximately 1.1 million pounds (500 metric tons) per year.

Presidential Executive Orders

The Council directed staff to send letters to the Department of Commerce and Department of Interior regarding President Biden’s Executive Order 14008 on Tackling the Climate Crisis at Home and Abroad. The letters will address strategies and conservation of 30% of waters by 2030 and provide information on how to increase the resilience of fisheries and protected species. Regarding the President’s EO 13985 on advancing racial equality and underserved communities, the Council asked staff to review the EO as it applies to the Council’s fishery ecosystem plans, programs and Pacific Island fishing communities.

Council Executive Director Kitty Simonds emphasized that “historically, all of our indigenous people in the Western Pacific Region are underserved, marginalized and adversely affected by persistent poverty and inequality.”

Oceanic Whitetip Sharks and Gear Changes in the Hawai‘i Longline Fishery

The Council took a step towards a regulatory change to prohibit the use of wire leaders in the Hawai‘i deep-set longline fishery, including a requirement to remove trailing gear from Endangered Species Act-listed oceanic whitetip sharks. This supports the Hawaii Longline Association (HLA) initiative to voluntarily switch from wire to monofilament nylon leaders announced in December 2020 and helps to address the Council’s domestic obligations for the relative impacts of U.S. vessels on international overfishing of Western and Central Pacific Ocean oceanic whitetip sharks.

The Hawai‘i longline fishery uses wire leaders as a safety measure to prevent gear flyback, an unintended consequence of using required weighted branch lines. However, wire leaders make it difficult make it difficult to remove the terminal portion of the branch line from sharks and other protected species that cannot be brought on board.

A joint public comment from HLA, The Ocean Foundation and The Pew Charitable Trusts emphasized their shared concern for the oceanic whitetip shark stock and support for the transition of the Hawai‘i-based fleet away from wire leaders, focus on crew training and agreement on key actions needed to improve the status of the stock.

International fishery commissions have adopted nonretention measures to help conserve oceanic whitetip sharks. To further address overfishing in international longline fisheries, the Council recommended increased observer coverage in areas where risk of interactions are highest, and improved shark handling and reduction of trailing gear to further safety at sea and promote post-release shark survivability.

The Council manages 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 and the U.S. Pacific Remote Islands Areas.

Western Pacific Scientists Recommend International Actions to End Overfishing for Striped Marlin

March 19, 2021 — HONOLULU — The following was released by the Western Pacific Fishery Management Council:

The SSC suggested several actions to end overfishing of North Pacific striped marlin in order to satisfy the Magnuson-Stevens Act (Section 304(i)) obligation both internationally via the Western and Central Pacific Fisheries Commission (WCPFC) and domestically. The Scientific and Statistical Committee (SSC) of the Western Pacific Regional Fishery Management Council made these and other recommendations during its three-day virtual meeting this week.

International recommendations included improving standardized reporting of billfish catch and discards for all WCPFC fisheries; using circle hooks in all WCPFC longline fisheries; limiting WCPFC member catches to approximately 1 million pounds (500 metric tons) per year; and supporting a consultative rebuilding plan.

A new stock assessment may be provided in 2022 and the SSC proposed that discard mortality (fish that don’t survive capture and release) be included within future rebuilding scenario analyses. The SSC also recommended that future rebuilding efforts utilize a phased-in approach over several years based on a target catch rate rather than a rebuilding timeline.

To support U.S. Pacific Territory data collection efforts, the SSC recommended the integration of creel survey, commercial receipt book, biosampling and app-based data collection systems, such as the Council’s Catchit Logit app, to generate the necessary data from different segments of the fisheries. The Council, territorial fishery management agencies and NMFS are working closely to meet the requirements for stock assessments and address deficiencies in data-limited or data-poor fisheries.

The SSC also recommended supporting an experimental study to evaluate the effectiveness of various mitigation combinations to reduce seabird interactions in the Hawaiʻi shallow-set longline fishery. Currently, if setting off the stern of the boat, conservation measures require the vessel to start setting its gear one hour after sunset (night-setting), use blue-dyed bait and strategic discharge of fish parts and spent bait.

Night-setting, while considered to be a “gold standard” for seabird mitigation, prevents shallow-set longline fishermen from adjusting their setting time according to the moon phase to optimize swordfish catch. Fishermen have expressed interest in testing out a new combination of mitigation measures, including tori (bird scaring) lines, to improve operational efficiency while ensuring impacts to seabirds remain low in the fishery.

Recommendations made by the SSC on these and other matters will be considered by the Council when it meets March 23-25, 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 Drive, Hagatña, Guam. On the first day, NMFS will give a briefing on President Biden’s Executive Order 14008 on Tackling the Climate Crisis at Home and Abroad.

WPRFMC Scientists to Evaluate Prohibiting Wire Leaders in Hawaiʻi Longline Fishery

March 16, 2021 — The Western Pacific Regional Fishery Management Council’s Scientific and Statistical Committee will meet this week to take action on several items, including consideration of longline gear changes that could help give incidentally caught sharks greater opportunity to survive.

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 on the vessel. 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.

Scientists to Evaluate Prohibiting Wire Leaders in Hawaiʻi Longline Fishery, Consider Catch Limits

March 12, 2021 — The following was released by the Western Pacific Regional Fishery Management Council:

Scientists from throughout the Pacific will meet March 16 to 18, 2021, 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/139th-scientific-and-statistical-committee-meeting. Among the agenda items are the following:

Wire Leader Regulatory Amendment for the Hawaiʻi Longline Fishery
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 that would be implemented after the fleet’s voluntary transition. The SSC will provide scientific advice to the Council on potential impacts to target and nontarget stocks, ESA-listed oceanic whitetip sharks and other protected species, fishery participants and the range of alternatives under consideration.

Main Hawaiian Islands Deep-Seven Bottomfish Catch Limits
The Pacific Island Fisheries Science Center (PIFSC) released an update to the main Hawaiian Islands deep-seven bottomfish stock assessment with catch-and-effort data up to 2018 and fishery-independent survey data up to 2020 indicating the stock remains healthy. The assessment provided alternative catch levels at different risk levels of overfishing from 2021 to 2025 to specify new annual catch limits. The SSC will consider the new information to determine if a change in the current acceptable biological catch (508,000 pounds) is warranted.

Guam Bottomfish Rebuilding Plan
At the 184th meeting in December 2020, the Council received options to address the overfishing bottomfish stock condition in Guam based on a 2019 benchmark stock assessment. The Council selected a 31,000-pound ACL as its preliminary preferred alternative, which would rebuild the bottomfish stock within the required 10 years. Since then, Council staff received an updated biomass projection from PIFSC, which substantially changed the rebuilding timeframes of the options provided in December 2020. The SSC will review the new information, reconsider its preliminary preferred alternative and may provide recommendations to the Council regarding the rebuilding target as required by the Magnuson-Stevens Act.

North Pacific Striped Marlin Catch Limits
The North Pacific striped marlin stock is overfished and experiencing overfishing, requiring the Council to take steps to reduce the United States’ impact on the stock. The SSC will review alternatives and may recommend to the Council appropriate U.S. catch and/or effort levels for North Pacific striped marlin and international recommendations to move towards ending overfishing. U.S. Pacific fisheries, including the Hawaiʻi longline fishery, landed approximately 19% (about 796,000 pounds per year) of reported North Pacific striped marlin catch from 2013 to 2017. Japanese fisheries landed three and a half times that amount (almost 2.8 million pounds) per year over that same period, accounting for 60% of the total catch. Since 1975, U.S. fisheries have accounted for 6% of the historical North Pacific striped marlin catch, while Japan and Taiwan fisheries landed 83% and 9%, respectively.

Recommendations made by the SSC on these and other matters will be considered by the Council when it meets March 23-25, 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 will be posted at www.wpcouncil.org/meetings-calendars.

Yearbook: Fishing fleets flex

March 8, 2021 — With revenues up 3 percent in January and February of 2020, the industry was looking ahead to another strong year in the global marketplace.

In March, when restaurants across the country shuttered quickly under covid-19 outbreak restrictions, seafood supply chains ground to a halt in the early days of the pandemic. Fishermen who had been out harvesting to supply the once-solid market were stuck with their catch left unsold and their boats tied up.

In early March, New Jersey fisherman Gus Lovgren was headed to port after a Virginia summer flounder trip when his wife called him, “saying they’re shutting the country down, basically,” he recalled.

“We had been getting $1.75 to $2 (per pound). In the end we got, I think, 60 cents,” said Lovgren. “The market was flooded, and there was nothing we could do.”

Right out of the gates in April 2020, the Hawaii Longline Association worked with others in Hawaii’s fishing industry to donate 2,000 pounds of fresh seafood to Hawaii Foodbank, and planning larger deliveries.

The initial donation, coordinated with the with United Fishing Agency’s Honolulu auction, the Hawaii Seafood Council, Nico’s Pier 38, and Pacific Ocean Producers, “is the beginning of a new pilot program with the Hawaii Foodbank,” the association said.

“Through the partnership, Hawaii Foodbank plans to purchase $50,000 worth of seafood landed by Hawaii longline vessels,” according to a statement from the association. “The purchase will ensure that Hawaii Foodbank will be able to meet the needs of Hawaii residents facing hardship as a result of covid-19. It will also support Hawaii’s longline fishermen.”
