HAWAII: Hawaiʻi longline fishers experience ‘all-time low’ in profits

March 28, 2025 — Hawaiʻi’s longline fishers are facing record lows in profits, according to a recent report from the National Oceanic and Atmospheric Administration.

For years, NOAA’s Pacific Islands Fisheries Science Center has collected data on fishing trip costs and earnings for Hawaiʻi’s commercial longline fishery, and surveyed 60 fishers to get data for 2022.

PIFSC found that the average fishing vessel made around $808,000 in gross revenue that year. Of that, 54% went to trip costs like fuel, ice and bait, and 22% went to labor. After other costs, boat owners took home an average of 5%.

Adjusted for inflation, that’s an average of about $44,000 in profit.

“If we look at profitability over time for the Hawaiʻi longline fishery using our past efforts, we find that, adjusted for inflation, average profit per vessel in 2022 was unfortunately at an all-time low,” said Justin Hospital, supervisory economist at PIFSC.

Autonomous Vehicles Powered by Ocean Waves Support NOAA Fisheries Research

December 4, 2023 — Scientists from NOAA’s Pacific Islands Fisheries Science Center are using autonomous surface vehicles called Wave Gliders to study ocean health in Hawaiʻi. Wave Gliders are circumnavigating each of the Hawaiian Islands. They’re collecting data on ocean conditions that will be used to help estimate the impacts of climate change on marine ecosystems and fisheries across the state.

“We are primarily interested in measuring chlorophyll, which provides a good estimate of phytoplankton biomass in the ocean,” said Dr. Jamison Gove, an oceanographer with the Pacific Islands Fisheries Science Center and co-lead scientist on the project. “Phytoplankton are the basis for productive and healthy ecosystems, so knowing where and how much phytoplankton there are in the ocean aids in understanding the entire marine food-web,” added Dr. Gove.

The Building Blocks of Ocean Ecosystems

Phytoplankton are microscopic plants that live near the ocean surface. They are similar to land-based plants: They contain chlorophyll and require sunlight to live and grow. Phytoplankton are the base of the food chain. Their biomass—the total amount of them in a given region of the ocean—dictates fisheries yields and ecosystem productivity across the world.

Hawaii Longline Fishing Recovering from COVID-19

March 23, 2022 — Hawaii’s longline fishery became more active in 2021 as the state began its recovery from the COVID-19 pandemic, but the increase didn’t necessarily lead to more fish caught.

Commercial fish catch in Hawaii plummeted in 2020 as the coronavirus forced the closure of hotels, restaurants and other businesses, and along with them the demand for fish.

But Hawaii’s economy has been slowly returning to form, and in 2021 the state’s 146 longline fishing vessels made 1,734 fishing trips, up from the 1,679 in 2020.

Additionally, the vessels set out 63.5 million hooks during their fishing trips — a record number for the industry, said Russell Ito, a fishery biologist for the Pacific Islands Fisheries Science Center.

Ito on Wednesday presented an annual report on Hawaii’s longline fishery to the Scientific and Statistical Committee, an advisory body to the Western Pacific Regional Fishery Management Council.

WPRFMC Scientists Discuss Next Generation Data Collection, New Strategy to Advocate for Fisheries

March 21, 2022 — Fisheries data collection in remote areas, particularly islands spread hundreds of miles apart, is challenging. Scientists from Hawaii and those informing the Western Pacific Regional Fishery Management Council are looking for answers.

The Pacific Islands Fisheries Science Center Director Michael Seki presented the NOAA Next Generation Data Acquisition Plan (NG-DAP) to the Council’s Scientific and Statistical Committee this week. The Plan will guide data acquisition for the next 10 to 15 years. The fisheries and technologies to gather data have evolved and regional data needs have changed since the last plan was released in 1998, the Council said. The NG-DAP will use innovative technologies, modern fishery information collection systems, artificial and machine learning and advanced modeling tools to account for climate change, emerging ocean uses and ecosystem-based fisheries management.

While the NG-DAP is a nationwide effort, the plan will point out regional needs and highlight opportunities for potential partners and collaborators. NOAA plans to hold public workshops later this spring to gather input from stakeholders. The SSC noted that meetings should include fishing communities in the territories.

The Western Pacific Region is still challenged by data limitations due to little federal investment in collecting basic fishery-dependent data and life history information for the benefit of local underserved communities. The Council and SSC have, over the years, continuously identified research needs to the National Marine Fisheries Service, focusing on island and pelagic fisheries, ecosystems, protected species and human communities in order to sustainably manage fisheries in the region.

Success of the 2021 Mission to Clean up Marine Debris

September 27, 2021 — Scientists and divers from NOAA’s Pacific Islands Fisheries Science Center and local nonprofit Papahānaumokuākea Marine Debris Project (PMDP) returned to Honolulu on September 22, 2021, from a 30-day mission. The team removed marine debris from the shallow reefs and shorelines of the Papahānaumokuākea Marine National Monument. These remote islands and atolls are centered among Pacific currents that carry lost and abandoned fishing nets and gear from all over the Pacific Ocean. The debris entangles wildlife and damages corals. Even during this mission, the team disentangled a 5-year-old female Hawaiian monk seal from derelict fishing rope.

The project staff collect valuable data during these missions:

Assessing the abundance and distribution of marine debris across Papahānaumokuākea
Evaluating rates of marine debris accumulation
Measuring habitat damage and the negative impacts of marine debris on coral reefs
Gauging recovery of coral reefs after marine debris removal
Increasing public awareness of marine debris issues through communication and outreach

The team of 16 divers expected to remove more than 110,000 pounds of derelict fishing nets, plastics, and other marine debris. Over only 18 days, they collected even more—nearly 124,000 pounds of debris—from these islands, atolls, and reefs of the monument:

Kamokuokamohoaliʻi (Maro Reef)—nearly 43,000 pounds
Kuaihelani (Midway Atoll)—approximately 24,500 pounds
Manawai (Pearl and Hermes Atoll)—23,650 pounds
Hōlanikū (Kure Atoll)—nearly 16,000 pounds
Kapou (Lisianski Island)—nearly 11,500 pounds
Kamole (Laysan Island)—more than 5,000 pounds

US Pacific Fishery Managers Support Climate Change Research to Inform Management Decisions

September 22, 2021 — The Western Pacific Regional Fishery Management Council voted today to approve several plans aimed at improving research and data in the region. The Council’s work relies on robust scientific information for its fishery management decisions. The Council and its advisors developed research priorities with the Pacific Islands Fisheries Science Center, setting the direction for the future.

Climate change is a high priority, in line with the Biden Administration’s efforts to mitigate the impacts and enhance fisheries resilience. Addressing the shift in distribution of stocks and fishing effort due to changes in oceanographic features is a good example.

The Council’s Scientific and Statistical Committee Three-Year Plan focused its priorities on science that directly supports fishery management. A major focus is helping fishing communities to understand the value of data for fishery sustainability.

The Council’s five-year regional research plan is mandated by the Magnuson-Stevens Act. The plan covers research priorities for pelagic and island fisheries, protected species, human communities, cooperative research and management strategy evaluation.

The Council also endorsed the Fishery Data Collection and Research Committee’s strategic plan for 2022 to 2026. The overarching goals of the plan are to:

Build local agency capacity to improve fishery-dependent data collection.
Provide non-peer-reviewed reports and unpublished datasets.
Conduct science and research to support ecosystem-based fishery management.

The Council concluded the first day of its three-day virtual meeting today. The meeting continues tomorrow with decisions on the American Samoa bottomfish rebuilding plan and initial action on seabird mitigation in the Hawai‘i longline fishery. Instructions on connecting to Webex, agendas and briefing documents are posted at www.wpcouncil.org/meetings-calendars.

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 (CNMI) and the U.S. Pacific Remote Islands Areas.

Modernizing Catch Reporting in Hawaii and American Samoa Longline Fisheries

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

The National Marine Fisheries Service (NMFS) announced last week that the requirement for the Hawai‘i and American Samoa pelagic longline fisheries to electronically report their catch will be effective Sept. 7, 2021. This regulation is intended to reduce human error, improve data accuracy, save time for fishermen and NMFS, and provide more rigorous monitoring and forecasting of catch limits.

Development of the electronic reporting (ER) system for the Hawai‘i and American Samoa longline fisheries ramped up about 2014. After several years of development, the Pacific Islands Fisheries Science Center (PIFSC) began rolling out the tablets in 2019 for Hawai‘i longline vessels to use on a voluntary basis. At its September 2020 meeting, the Western Pacific Regional Fishery Management Council took final action recommending mandatory implementation.

To support PIFSC’s ER outreach to Vietnamese-American fishermen, the Council hired a Vietnamese-speaking staff. The outreach team introduces the tablet, conducts training and follows up with them after their initial trips to help resolve any issues.

Approximately 115 of the 150 Hawai‘i longline vessels have been trained and are now voluntarily using the tablets ahead of mandatory implementation. PIFSC is also coordinating with local NMFS staff in American Samoa to roll out training for the longline vessels based in Pago Pago. PIFSC will continue to provide training support to bring all vessels into compliance.

After Sept. 7, 2021, Hawai‘i longline vessels and Class C and D American Samoa longline vessels will be required to use electronic logbooks once the following criteria are met:

NMFS notifies the permit holder of the requirement.
Permit holders have received the ER tablet (at no cost).
The vessel operator has obtained an individually assigned user account from NMFS.

Fishermen will be allowed to use paper logbooks as a backup if vessels experience any electronic logbook or transmission problems.

In the past, longline captains filled out one logbook sheet for every day of fishing during their trip. Then they submitted their full trip’s log sheets to PIFSC when they returned to port. The data were verified and manually entered into a database by PIFSC staff.

There was often a several week delay between when the paper logbook was filled out by the captain and when it became available to fishery managers to compare the latest catch information with catch quotas. The delay creates a significant challenge to predict when the fleet will reach annual catch limits, such as for bigeye tuna.

Electronic logbooks automate and streamline many of these steps, allowing near-real-time catch reports. Each vessel is equipped with a tablet loaded with ER software. The tablet is connected to a vessel monitoring system, which transmits the daily logbook data via satellite to NMFS. Daily catch data submission will be required under the new rule while operating in U.S. waters around Hawai‘i, American Samoa and adjacent high seas.

Back to the Field: NOAA Biologists Return to Papahānaumokuākea to Study and Protect Hawaiʻi Wildlife

July 16, 2021 — The following was released by NOAA Fisheries:

A team of biologists from NOAA’s Pacific Islands Fisheries Science Center is setting off for a field season in the remote islands of the Papahānaumokuākea Marine National Monument. The team departed Honolulu on the M/V Kahana II July 10, and the ship will return August 6. However, most of the biologists will stay behind for a season of hard work collecting data on some of the iconic threatened and endangered species of Hawaiʻi—Hawaiian green sea turtles and Hawaiian monk seals.

The Work of NOAA Field Biologists in the Monument

The primary goal of this research cruise is to set up biological field camps at five sites within the monument:

Lalo (French Frigate Shoals)
Kamole (Laysan Island)
Kapou (Lisianski Island)
Manawai (Pearl and Hermes Reef)
Hōlanikū (Kure Atoll)

Setting up camp on these remote islands is a big undertaking—each camp needs tents and all of the food, fresh water, scientific equipment, and safety supplies that teams of three to seven biologists will need for their stay of over 2 months. The research cruise team will also conduct monk seal surveys at islands where they do not establish camps—Nihoa, Mokumanamana (Necker) and Kuaihelani (Midway Atoll).

Once camps are established, the real work begins. Hawaiian monk seal biologists at the five camps will survey the islands to get an accurate count of monk seals. They will also monitor moms and pups to track reproductive success and attach identification tags to seals’ flippers to help track individuals through their lives. At two of the sites (Lalo and Pearl and Hermes Reef), the team will use an underwater device (sound trap) to record monk seal vocalizations and understand the noises they hear.

Marine turtle biologists will join a team of two who have been at Lalo since early spring. The turtle team will count and tag male turtles and nesting female turtles, monitor nest success, and collect samples from hatchling turtles.
