Federal judge blocks lobster fishing ban in stretch of Gulf of Maine

October 18, 2021 — A federal judge in Maine on Saturday blocked a seasonal ban on traditional lobster fishing in a stretch of offshore waters in the Gulf of Maine that regulators say is needed to save the endangered North Atlantic right whale from extinction.

In his 28-page ruling, U.S. District Judge Lance Walker said regulators had relied on “markedly thin” statistical modeling instead of hard evidence to show the nearly thousand-square-mile area they had planned to close was really a hot spot for the imperiled whale.

While the area targeted for closure may be a viable habitat for the right whale, there is no hard proof the whales actually gather there, or even pass through that part of the Gulf of Maine, with enough frequency to render it a “hotspot,” Walker wrote.

The National Marine Fisheries Service had only just this year deployed acoustic devices along the Maine coast that can detect the presence of right whales through their song, Walker noted. When available, such evidence of a hot spot is preferable to statistical likelihoods.

Trawler bycatch debate heats up after Alaska records dismal 2021 chinook salmon returns

October 15, 2021 — Fishermen are calling for state and federal fisheries managers to make changes to salmon bycatch limits for trawlers as chinook salmon numbers plummet across Alaska.

Chinook salmon returns were dismal virtually everywhere in Alaska this year, from Southeast to the Bering Sea, with few exceptions. That follows a trend, as abundance has declined over roughly the last decade. Commercial fishermen have lost most of their opportunity to harvest kings, and sport fisheries have been restricted. Now subsistence fisheries are being reined in to help preserve the runs.

The North Pacific Fishery Management Council is debating changes in its meeting this month. Trawlers, which use weighted nets to drag either along the bottom or in midwater, are permitted a certain amount of bycatch as they fish for their target species, the largest of which is pollock. Bycatch is always a heated issue, but it is especially so now.

The Alaska Department of Fish and Game informed the council in a letter dated Sept. 23 that three index species that it uses to track king salmon runs in the Bering Sea — the Unalakleet, Yukon, and Kuskokwim rivers — didn’t reach a threshold necessary to maintain the current bycatch allowances. That threshold is set at 250,000 fish between the three rivers; this year, there were 165,148.

The Kuskokwim’s run came within its forecasted range, but the other two fell short.

The shortfall in salmon this year hit fishing communities hard, particularly among subsistence fishermen. Amos T. Philemenoff Sr., president of the Aleut Community of St. Paul Island, wrote to the board that the salmon shortages in the Arctic-Yukon-Kuskokwim region this year have affected the island’s subsistence traditions. Donations of salmon from commercial harvesters to replace the lost food do not replace the traditions, he said.

Tribal, commercial fishing groups call for drastic reductions in trawl salmon bycatch

October 14, 2021 — Fisheries managers allow whitefish trawlers to inadvertently scoop up halibut, crab and salmon in their nets. The bycatch rate is relatively low, but because the trawlers catch so much of their target species, the unintended harvest adds up.

In rural western Alaska, where chum and king salmon runs have been performing poorly, the bycatch is raising alarms. While the bycaught salmon is often donated to food banks, it’s of little assurance to those living along the Yukon and Kuskokwim rivers, where subsistence is a way of life.

“We eat dry fish like people from the Midwest eat bread, with every meal,” Mary Peltola told the North Pacific Fishery Management Council this month. She’s the executive director of the Kuskokwim River Inter-Tribal Fish Commission, and lives in the largely Yup’ik community of Bethel. “Our babies teethe on dry fish, it’s the first food most Yup’iks eat, and it’s something that we crave year-round.”

She testified that fishing on the Kuskokwim has been severely restricted to preserve wild salmon stocks. Meanwhile, trawlers haven’t faced new restrictions of their own as they scoop up lucrative whitefish like pollock, cod and halibut. She’s asked the council to work to put an end to bycatch in the industrial commercial trawl fleet.

LOUISIANA: Judge’s order delays implementation of Turtle Exclusion Devices for vessels

September 29, 2021 — A US District Judge has granted a motion from the Department of Wildlife and Fisheries (LDWF) for a preliminary injunction on the federal Turtle Exclusion Devices for some vessels.

LDWF says the order delays implementation of the requirements of TEDs in skimmer vessels 40 feet in length or greater in Louisiana inshore waters until February 1, 2022. The motion for the injunction was granted on September 9, 2021.

LDWF says that on December 20, 2019, the Final Rule was published requiring skimmer vessels 40 feet in length or greater to have an approved TED installed by April 1, 2021. In March 2021, NOAA delayed implementation of the Rule to August 1, 2021 due to a lack of outreach and availability of TEDs caused by the COVID-19 pandemic.

In April 2021, NOAA released an Advance Notice of Proposed Rulemaking to require TEDs on all skimmer vessels, regardless of vessel length.

Maine Lobstermen’s Association Sues Feds Over Right Whale Protection Plan

September 28, 2021 — The Maine Lobstermen’s Association has filed suit against the federal government over its plan to protect endangered North Atlantic right whales from becoming entangled in lobster gear.

MLA executive director Patrice McCarron says a 10-year plan issued by the National Marine Fisheries Service this summer should be revised to reflect actions the industry has already taken.

“We are literally on a course to have our fishery erased, eliminated in ten years, because the plan’s not based upon the science. And the first phase of the plan has weaknesses, too, not based upon the best available science,” she says.

New Study Develops Alternate Methods to Manage Gray Seal Bycatch

September 27, 2021 — The following was released by the Science Center for Marine Fisheries:

Marine mammal conservation is one of the top goals of U.S. ocean management. That is why it’s particularly important for regulators to have an accurate estimate of how fisheries and other ocean users may impact marine mammal populations. A new study looks at ways of strengthening and fine-tuning existing marine mammal management and assessing the impacts on one marine mammal population in the western North Atlantic, the gray seal.

The study, from Drs. André Punt, John R. Brandon, Doug DeMaster, and Paula Moreno, is the culmination of a 3-year research project led by Dr. DeMaster and conducted in collaboration with the scientists at NOAA’s Northeast Science Center, with funding from the Science Center for Marine Fisheries. It specifically examines a key variable in marine mammal management, the Potential Biological Removal (PBR) level.

Under the Marine Mammal Protection Act, marine mammal populations are managed according to their Potential Biological Removal (PBR), which determines the level of mortality (and serious injury) that is sustainable for each marine mammal population. When bycatch of a marine mammal population nears or exceeds its PBR level, restrictions are often imposed on nearby fisheries as a precautionary measure to prevent the population from becoming depleted.

In the case of gray seals, assessments of human-caused mortality levels are complicated by the fact that the gray seal population exists on both sides of the U.S.-Canada border. Determining when the gray seal PBR is exceeded is subject to errors due to incomplete information, meaning that certain management decisions could unnecessarily trigger fishing restrictions (termed by scientists as ‘false positives’) or needed restrictions are not imposed (known as ‘false negatives’). These restrictions often include catch limits of commercially valuable species, limits on what kinds of gear can be used, and other regulations that can be costly for the fisheries forced to adopt them.

To address this, the authors assembled the best available data on the western North Atlantic grey seal population and Canadian fisheries. This allowed them to produce two key estimates when assessing whether gray seal bycatch exceeds the PBR level. It used a more realistic, species-specific rate of gray seal maximum net production (i.e., 14.1% per year), rather than using a generic default value for other seal species (12% per year). If adopted by the National Marine Fisheries Service (NMFS), this would increase gray seal PBR level by 18%. The study also used an extrapolated bycatch estimate for adjacent Canadian waters, which had not previously been attempted.

The study found that, in comparison to the base model currently used by NMFS, this approach is more robust to transboundary movements and uses a more accurate estimate of maximum net production of gray seals, allowing managers to adopt more appropriate management measures on fisheries while still achieving precautionary conservation goals for the grey seal population. The results can provide a blueprint for other assessments of marine mammal-fishery interactions for similar transboundary marine mammal stocks.

Some sharks are more likely to die after ‘catch and release,’ study finds. Here’s why

September 24, 2021 — Longlining, a commercial fishing technique that drags a main line with baited hooks through the water, is convenient when catching massive amounts of swordfish and tuna, but it also traps what experts call “bycatch” — unintended victims that may face dark fates after release back into the ocean.

Sharks are often attracted to and caught on these baited longlines; it’s one of the many culprits behind declining shark populations. Certain rules called “no-take regulations” require fishermen to release some species when accidentally hooked, but a new study of over 300 sharks found that some are much more likely to die after “catch and release” than others. The study was published Sept. 15 in the journal PLOS One.

“The assumption behind no-take regulations is that the shark will swim away and live out its normal life after it’s released, but we know that for some sharks, that’s not true,” study lead author Dr. Nick Whitney, senior scientist at the New England Aquarium’s Anderson Cabot Center for Ocean Life in Massachusetts, said in a news release.

After five years of longline fishing that targeted five of the seven most commonly caught species in the Gulf of Mexico and Florida Keys, the researchers learned as many as 42% to 71% of blacktip and spinner sharks will die after being caught and released alive. Others, such as sandbar and tiger sharks, were more resilient; only 3% or fewer died after release. Bull sharks were also one of the more hardy species. The animals were caught near Madeira Beach, Key West and Naples, Florida.

The team learned 90% of the post-release deaths occurred within five hours of returning to the water, and 59% occurred within just two hours. Blood samples and tracking data revealed the stress of the capture process, or injuries acquired during it, leads to the unnecessary and disproportionate demise of some sharks.

US Senate approves drift gillnet ban again

September 21, 2021 — A bill banning large drift gillnets from being used in federal waters has unanimously been approved in the U.S. Senate.

Now S.273, also known as the Driftnet Modernization and Bycatch Reduction Act, heads to the U.S. House of Representatives for consideration. The bill’s chances there are good, considering the legislative body passed the same measure last year. However, former U.S. President Donald Trump vetoed the bill on 1 January, claiming it would lead to more imported seafood entering the country.

Maine’s Next Generation Of Lobstermen Brace For Unprecedented Change

September 20, 2021 — The latest federal rule, announced on Aug. 31 by the National Oceanic and Atmospheric Administration (NOAA), is part of a plan to stop endangered North Atlantic right whales from getting caught in fishing gear by 2030.

The agency estimates that the population’s decline has accelerated in recent years, with 368 right whales remaining. NOAA has documented 34 right whale deaths since 2017, with at least nine of those mortalities confirmed to have been caused by entanglements in fishing gear, including gear used by commercial gillnet or lobster and crab fisheries on the East Coast.

NOAA’s new rule requires lobstermen to use gear with state-specific markings that can be traced if a whale gets caught, among other modifications such as weak points in fishing lines that allow entangled whales to break free. The rule will also allow lobstermen to use so-called ropeless gear — a costly and controversial new technology that’s still in the early stages of development — in fishing areas that will be closed in certain seasons.

“The beauty of the lobster industry is that there’s been a place for everybody,” says Patrice McCarron, executive director of the Maine Lobstermen’s Association. “We’re at risk of putting too many barriers in that are really going to create winners and losers, so it’s scary.”

McCarron says fishermen want to do their part to protect whales, but she says no Maine lobster gear has ever been confirmed to have caused the serious injury or death of a right whale. A NOAA spokesperson counters that its scientists are unable to determine the source of most entanglements and nearly half of mortalities go unobserved.

NMFS funding $2.2 million for bycatch reduction projects

September 17, 2021 — NMFS funding $2.2 million for bycatch reduction projects. Federal officials announced $2.2 million in funding is being awarded to partners around the U.S. to support innovative research through the NMFS Bycatch Reduction Engineering Program.

Incidental bycatch of non-target fish, protected marine mammals and sea turtles “can have significant biological, economic, and social impacts,” NMFS said in announcing the awards.

“Preventing and reducing bycatch is a shared goal of fisheries managers, the fishing industry, and the environmental community. Working side-by-side with fishermen on their boats we’ve developed solutions to some of the top bycatch challenges facing our nation’s fisheries.”

At the top of this year’s list are projects to develop so-called ropeless gear for the Northeast lobster and other fixed-gear fisheries, to reduce entanglement incidents with the highly endangered North Atlantic right whale population, recently estimated to number less than 400 animals.
