How Scientists Are Using Real-Time Data to Help Fishermen Avoid Bycatch

April 15, 2019 — From 1990 to 2000, fishermen seeking swordfish off the coast of California accidentally caught and killed over 100 leatherback and loggerhead sea turtles, and injured many more.

In 2001, the federal government established the Pacific Leatherback Conservation Area, a 250,000-square-mile region off the coast of California that is off-limits to fishing boats from August through November.

Since then, the number of turtles killed as bycatch has plummeted, but a handful of animals still die from being entangled in fishing nets each year—too many, environmental advocates say. And at the same time, the closure of the giant oceanic region means the once-$15 million swordfish industry has become a $2 million industry, and the number of boats plying the waters has decreased significantly.

Scientists and ocean advocates are hoping to find a way to both protect sea turtles and other threatened species and help fishermen make a living. To this end, many are looking at dynamic ocean management, a strategy that uses advances in real-time data collection to help fishing vessels meet fish where they are—and avoid all other bycatch.

Western Pacific Council to Address Sea Turtle Interactions with Sustainably Caught Hawaii Swordfish Longline Fishery

April 2, 2019 — The following was released by the Western Pacific Regional Fishery Management Council:

The Hawaii longline swordfish fishery closed on March 19 after it interacted with the 17th loggerhead turtle for the year. All of the turtles were released alive. The fishery has 100 percent observer coverage, i.e., a federal observer is on every vessel on every trip to monitor protected species interactions. This observer coverage level is extraordinary and an order of magnitude higher than other competing fishing nations. The Western and Central Pacific Fisheries Commission requirement is only 5 percent coverage, which most other nations have not met. The United States also operates with measures to reduce and report bycatch at levels that other fishing nations do not implement.

”Closure of this healthy, underutilized fishery is not only an economic loss for the Hawaii fishery but also has no discernible stock conservation benefit for the Pacific,” notes Council Executive Director Kitty M. Simonds. ”The catch from the Hawaii fleet will be supplanted by the catch from foreign fleets that have far less monitoring and bycatch mitigation.”

The United States was usurped by Taiwan in the late 1990s as the second leading fishing nation to harvest North Pacific swordfish (Japan leads in landings) as US landings declined. The Hawaii fishery accounted for between 55 percent (2017 and 2008) to 34 percent (2012) of the US domestic swordfish landings.

  • The Western Pacific Regional Fishery Management Council Biological Opinion (BiOp) Review Advisory Panel meeting will review the BiOp for the Hawaii-based shallow-set longline fishery for swordfish on April 12 from 9 a.m. to 11 a.m. Hawaii Standard Time (HST).
  • The 177th Council meeting will be held April 12 from 1 p.m. to 4 p.m. (HST). The Council will discuss the Draft BiOp for the Hawaii-based shallow-set longline fishery for swordfish as well as management of loggerhead and leatherback sea turtle interactions in that fishery (final action).

Projections of the stock through 2026 along with recommendations by the International Scientific Committee for Tuna and Tuna-like Species in the North Pacific Ocean determined that the stock is not fully utilized and could withstand a significant, yet sustainable increase in harvest. Such an increase in harvest of about 50 percent from recent catches to near maximum sustainable yield would maintain a healthy stock.

The North Pacific swordfish stock was assessed in 2018 and determined to be nearly double spawning stock biomass at maximum sustainable yield (87 percent over SSBMSY) with fishing mortality determined to be less than half of fishing mortality at maximum sustainable yield (45 percent of FMSY). Spawning stock biomass has increased nearly by 10,000 metric tons since 2000 and has not breached below its commonly used biological reference point (SSBMSY) in any year in the stock’s assessment timeline (1975-2016). The stock had only been considered to be experiencing overfishing (breaching FMSY) in 1993.

Lack of supply from the sustainable Hawaii shallow-set fishery may increase pressure on other swordfish stocks to meet market demands. This may have inadvertent consequences to stocks, such as those in the Atlantic, that are not as healthy as the North Pacific stock.

Warming oceans cast a chill over New England’s sea turtles

March 26, 2019 — If we ignore the dangerously shifting global climate system, there will be consequences: more extreme rainfall, more intense hurricanes, drier and longer wildfire seasons, and continued sea level rise all loom on the horizon. In fact, extreme weather changes are already being seen around the globe.

But one of the lesser known, already visible impacts of climate change is on sea turtles. A recent paper, led by UMass Amherst doctoral candidate Lucas Griffin, links a rapidly warming Gulf of Maine to increased sea turtle strandings on Cape Cod.

“We were surprised the results suggested this increase was linked with warmer sea surface temperatures,” Griffin says. The scientists originally thought the strandings might be associated with how many young sea turtles hatched. But turtles, it turns out, are just one of many Gulf of Maine species “exhibiting a similar shift in both habitat distribution and in phenology patterns.”

The Gulf of Maine is in crisis: The region is warming faster than 99 percent of the global ocean. Fish stocks are moving north, key food web events like the spring plankton bloom are occurring earlier in the year, and regional waters are staying warmer for longer. Griffin’s team used both machine learning and Bayesian statistical methods—using existing data and probability to quantify uncertainty in inferences—to analyze the relationship between water temperatures and the number of cold-stunned turtles, the potentially lethal turtle equivalent of hypothermia. The innovative approach confirmed what local naturalists and wildlife biologists had been observing for years: Warmer waters in the region actually lead to an increased threat of cold-stunning.

How to keep conservation policies from backfiring in a globally connected world

March 13, 2019 — For many years environmentalists have urged the public to “think globally, act locally” — consider the health of the planet, then take action in your own community.

But this approach can have unintended consequences. In a recent study, I worked with colleagues from academia, government and the nonprofit world to gather examples of fishery, forestry, agriculture and biofuel policies that appeared successful locally, but on closer inspection actually created environmental problems elsewhere, or in some cases made them worse.

For example, in my field of fisheries ecology and management, one strategy for managing the problem of bycatch — when fishermen accidentally catch non-target species, such as sharks, sea turtles, and dolphins — is to reduce local catch limits. But when the United States curtailed Pacific swordfish catch between April 2001 and March 2004 to protect sea turtles, U.S. wholesalers imported more swordfish from other countries’ fleets operating in the Western and Central Pacific.

CALIFORNIA: Can sustainably caught swordfish make waves on the Central Coast?

December 31, 2018 — Will sustainably-caught swordfish receive a wave of support from Central Coast fishermen, consumers and restaurateurs?

Clean-fishing advocates sure hope so as efforts continue to phase out the use of drift gillnets — the mile-long, 100-foot-wide nets currently used to catch swordfish — which  commonly collect and kill protected species like whales, dolphins, and sea turtles.

On Sept. 28,  Gov. Jerry Brown signed Senate Bill 1017, which requires the state Department of Fish and Wildlife get funding for and enact a transition program that would help fishermen switch to alternative fishing gear.

Under the program, up to $10,000 would be offered for fisheries to turn in their drift gillnet permits, and transition to “clean-fishing” gear.

The California Department of Fish and Wildlife has until March of 2020 to roll out the drift gillnet “buyout.” However, the department still needs to raise $1 million to trigger the revocation of all drift gillnet permits. The money would have to come from federal funding or private donor sources.

NEW YORK: A Push for Offshore Oil

December 7, 2018 — A recent move by the Trump administration could lead the way to oil and gas exploration and extraction off the Atlantic coast.

The Washington Post reported on Friday that the National Marine Fisheries Service, a division of the National Oceanic and Atmospheric Administration, has approved five requests that will allow companies to conduct seismic surveys. The “incidental take” authorizations allow companies conducting such surveys — geophysical companies working on behalf of oil and gas corporations, The Post reported — to harm marine life as long as it is unintentional.

Such surveys would be conducted using seismic air guns, which emit loud blasts on a recurring basis, 10 seconds apart for 24 hours a day, often for weeks at a time, according to the environmental group Greenpeace. The sonic blasts, or “pings,” penetrate through the ocean and miles into the seafloor and can harm whales, dolphins, sea turtles, and fish. They can result in temporary and permanent hearing loss, habitat abandonment, disruption of mating and feeding, beachings, and death, according to Greenpeace.

California seeks plan to protect whales and Dungeness crab fishery

December 3, 2018 — Crabs are a big deal in California as one of our oldest and most valuable fisheries. They are often a treasured part of holiday feasts and they supply jobs to coastal communities. Whales are a big deal, literally, as the most majestic, largest animals swimming off our shore. What the California Department of Fish and Wildlife has done in the past several years with our partners to prevent whale entanglements in fishing gear is a big deal, too.

California’s ocean waters are home to one of the most productive marine ecosystems in the world, hosting a diverse assemblage of migrating birds, marine mammals, sea turtles, and fish and invertebrate species. Protecting the ocean is a high priority for Californians.

That is why our department is taking actions to protect the whales and our prized crab fishery. The department is working to create a conservation plan that will analyze the effects of crab fishing on whales, identify steps to minimize the risk of whale entanglements in the crab fishing gear, secure funding to implement the plan, and submit it to the federal government for needed approval.

After decades of rescuing stranded sea turtles, NOAA’s Galveston lab plans to scale back

October 22, 2018 — The sea turtle was almost dead, stranded at the high tide line on a Galveston beach.

It had a thick coating of algae growing on its outer shell. Its body was thin, its eyes sunken. It wasn’t moving.

A beachgoer spotted the creature earlier this month and called a hotline for reporting stranded sea turtles. As soon as the phone rang, the NOAA Fisheries laboratory in Galveston sprang into action.

An employee collected the 40-pound turtle from the beach and brought it back to the lab. It was a Kemp’s ridley turtle — a critically endangered species — and it didn’t look good.

“It was basically one step away from being comatose,” said Ben Higgins, who manages the sea turtle program at the Galveston lab. “At one point, the staff came and got me and said, ‘We think it might be dead.’”

But it wasn’t dead. The NOAA staff put the turtle in a van and drove it to Houston. By the next morning, the turtle was sprawled out on an exam table at the Houston Zoo, letting senior veterinarian Dr. Joe Flanagan prod at it with purple-gloved fingers. The turtle got X-rays, blood work and a full physical exam.

The diagnosis: Dehydration and a touch of pneumonia.

“We got it just in time,” Higgins said. “It was very close to leaving us.”

But with some squid in its system and a prescription for antibiotics, the turtle was taken back to Galveston to recover in NOAA’s lab.

It’ll spend the winter in the lab, getting food and medicine and a heated tank. And if all goes well, it will be released back into the Gulf of Mexico sometime after the winter, when it can survive in the wild again.

California bans giant ocean fishing nets blamed for killing sea turtles, whales

September 28, 2018 — Ending years of controversy and debate, Gov. Jerry Brown late Thursday signed a new law phasing out the use of giant ocean fishing nets used to catch swordfish, but blamed for accidentally killing sea turtles, dolphins and other sea creatures.

The bill, SB 1017 by state Sen. Ben Allen, D-Redondo Beach, requires the state to set up a program to buy back nets and fishing permits from commercial fishermen who work in the state’s drift gill net fishery.

The nets — giant nylon curtains that can stretch one mile long and extend 100 feet underwater — are used mostly by fishermen between San Diego and Big Sur. Although they are intended to catch swordfish, thresher shark and opah, studies have shown that they entangle dozens of other marine species, including whales, dolphins, sea lions and sea turtles, fish and sharks. Those animals, known as bycatch, are often thrown back overboard, injured or dead.

“There is no longer room in our oceans for any fishery that throws away more than it keeps,” said Susan Murray, deputy vice president for Oceana, an environmental group with offices in Monterey that pushed for the new law.
