Study seeks origins of ghost nets that haunt Hawaii’s shores

May 27, 2021 — Ghost nets” from unknown origins drift among the Pacific’s currents, threatening sea creatures and littering shorelines with the entangled remains of what they kill.

Lost or discarded at sea, sometimes decades ago, this fishing gear continues to wreak havoc on marine life and coral reefs in Hawaii.

Now, researchers are doing detective work to trace this harmful debris back to fisheries and manufacturers — and that takes extensive, in-depth analysis on tons of ghost nets.

The biggest concern is that derelict gear keeps killing fish and other wildlife such as endangered Hawaiian monk seals, seabirds and turtles long after it’s gone adrift, said Drew McWhirter, a graduate student at Hawaii Pacific University and one of the study’s lead researchers.

“These nets bulldoze over our reefs before they hit shore,” McWhirter added. “They leave a path of destruction, pulling coral heads out, and can cause a lot of ecological damage.”

Ghost nets foul oceans throughout the world, but the Hawaiian Islands — with the Great Pacific Garbage Patch to the east and another gyre of floating trash to the west — are an epicenter for marine waste.

Joel Moribe, Endangered Species Biologist

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

What do you do at NOAA Fisheries?

I am an endangered species biologist for the Pacific Islands Regional Office, based out of O‘ahu, Hawai‘i. I do Section 7 consultations, natural resource program coordination, acoustics, effects analysis, effect minimization, and species protection.

Would you tell us a little bit about yourself?

I have more than 20 years of experience as a marine scientist, Endangered Species Act expert, and effects and project analyst. Before coming to the Pacific Islands Region, I spent 14 years in the Pacific Northwest conducting project analysis for the protection of salmon and killer whales. I also spent 3 years with the Navy as an endangered species project manager. And I actually do some fieldwork … sometimes!

What are a few words that describe you?

Hawai‘i born and raised, turtle lover, monk seal lover, coral lover and rescuer, entanglement and debris hater, scuba diver, free diver, University of Southern California Trojan, corgi lover, poi eater.

Why did you get into this field?

I’ve been fishing on O‘ahu since I was a very young child. Over the years I had noticed that fish were more difficult to catch, and conditions of the habitat were worsening. I routinely witnessed people violate laws, even within my own family. I knew I had to do something, or we would lose everything.

US West Coast is vanguard of direct-to-consumer seafood phenomenon

May 20, 2021 — COVID-19 permanently changed how consumers buy seafood – and food in general. Many Americans now want to receive delivery of their favorite food items at their homes, providing significant new business for seafood suppliers and wholesalers.

Moss Landing, California, U.S.A.-based Santa Cruz Fish Company and Honolulu, Hawaii-based Honolulu Fish Co. are two companies benefiting from the direct to consumer (DTC) trend.

Hawaii’s Fishermen Are Worried About China’s Fleet. So Is The Military

May 17, 2021 — Hawaii’s commercial fishermen and the U.S. military have a potential threat in common — China’s fleet of government-subsidized ships that has been straying into more distant waters in search of seafood and more influence.

Local longliners have reported seeing increasing numbers of Chinese vessels near the islands, accusing them of overfishing and intimidating tactics.

Sometimes the ships are fishing, sometimes they’re making their way into the eastern Pacific and sometimes they’re seemingly just sitting at sea, says Eric Kingma, executive director of the Hawaii Longline Association.

He noted that a group of Chinese vessels seemed to be loitering north of Midway Atoll National Wildlife Refuge last week. “What are they fishing for? I don’t know,” said Kingma. “But it’s an example of them being close to Hawaii and, we believe, getting closer.”

HAWAII: Marine debris research team fishes for clues in tons of ‘ghost nets’

May 10, 2021 — In an open-air structure called the “Net Shed” a team from Hawaii Pacific University’s Center for Marine Debris Research picks through a tangled mess of fishing nets.

They’re surrounded by mounds of twisted twine.

“It’s about five tons inside the ‘Net Shed’ and probably three tons outside, waiting for analysis,” said Jennifer Lynch, co-director of HPU’s marine debris program.

She’s heading up the effort to untangle the nets, cut and measure pieces, and look for clues.

“Lengths and widths and twine diameter, twin twists, knotted versus knot-less nets. You name it. We’re documenting what these pieces are,” she said.

The netting came from the Northwestern Hawaiian Islands. HPU partnered with Papahanaumokuakea Marine Debris Project to bring it back last month.

“We brought back just under 95,000 pounds of plastics in total. And of that 80,000 pounds were specifically ghost nets,” said Drew McWhirter, who’s working on the project for his master’s degree in HPU’s Marine Science Program.

Hawaiian Monk Seals Join the Animal Telemetry Network

May 6, 2021 — The following was released by NOAA Fisheries:

For more than two decades, NOAA has been tracking monk seals throughout the Hawaiian Archipelago as part of their larger effort to study and protect this endangered seal. And now you can see all of those tracks online! We have shared our entire archive of satellite telemetry locations through the Animal Telemetry Network. The public can view maps of seal travels and access data using this web portal. NOAA’s Hawaiian Monk Seal Research Program is looking forward to the collaborative research opportunities this opens up.

Hawaiian Monk Seals Tracked for Many Purposes

  • Research projects include learning about seal space use, travel distances, energy expenditure, habitat use, and foraging behaviors
  • Monitoring efforts include tracking seal survival and movement patterns after an intervention such as a veterinary surgery or rehabilitation
  • Management concerns include seals that may be translocated to avoid human-seal interactions or moved out of dangerous habitats

Studying how these animals use their environment is a crucial part of NOAA’s larger effort to understand the ecology of Hawaiian monk seals, identify and mitigate threats to survival, and work toward the recovery of this endangered species.

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.
