California assembly passes driftnet ban, bill heads to governor’s desk

September 6, 2018 — A bill that would end the use of drift gillnets for harvesting swordfish and thresher sharks in California now only needs the governor’s signature to become law.

Last week, the California Assembly voted 78-0 to pass SB 1017, which calls for eliminating the controversial nets over a four-year period. The nation’s most populous state is also the only one that still allows the use of the nets to collect swordfish and thresher sharks.

In June, the bill passed the state senate by a 33-0 margin.

Under the bill, the state would create a transition program by 31 March, 2020, to enable driftnet permit holders to use alternative gear. The transition program would include a buyout program created through a public-private partnership. Fishermen must surrender their nets in order to get compensation.

“Finally we have found a way to phase out their use and transition to a more humane alternative – without harming the commercial fishing industry in the process,” said State Senator Ben Allen, the bill’s sponsor. “This is a significant win for our ocean and for the California economy. We look forward to the governor signing it into law.”

According to data from NOAA Fisheries, there are approximately less than 20 active license holders using driftnets in California.

Conservation groups have long opposed the use of the mile-long, nearly invisible nets because they have been known to kill or injure dozens of other marine species, including whales, sea lions, and turtles. According to Oceana, the nets are responsible for killing more dolphins that all other American west coast fisheries.

After year in DC, Oliver reflects on fisheries progress

September 6, 2018 — Chris Oliver has had a busy year since he made the leap from Anchorage to Washington, D.C. to take the lead job at the National Marine Fisheries Service.

As soon as he arrived, there was an annual priorities document to review, he said at a recent roundtable discussion event hosted by the Kenai River Sportfishing Association in Soldotna. The document is both internally-facing and public to help guide NMFS’ decisions.

There were three goals listed in that document, the first of which was to ensure the sustainability of fisheries and fishing communities. He changed it to read “maximize fishing opportunities while ensuring the sustainability of fisheries and fishing communities.”

“There are a number of fisheries around the country where we’re not fully utilizing the available harvest whether it’s choke species or bycatch constraints or outdated regulations,” he said. “We’ve been approaching that pretty aggressively in that form. There’s not a huge amount of headroom in our wild stock harvest fisheries, but there’s some.”

The second was to manage protected species, including those under the Marine Mammal Protection Act and the Endangered Species Act. Under that, he added language to manage those species while supporting responsible fishing and resource development.

NOAA Funds Projects to Reduce Bycatch With Engineering

September 4, 2018 — A group of organizations is getting more than $2 million in grants to use engineering to try to reduce bycatch in fisheries.

Bycatch is the term for when fish and other animals are accidentally caught with gear that was seeking a different species. Bycatch poses problems for rare species of dolphins, turtles, sharks and other animals.

The National Oceanic and Atmospheric Administration is awarding more than $2.3 million to 14 projects as part of its 2018 Bycatch Reduction Engineering Program.

One of the recipients is Duke University, which will test the applicability of sensory-based bycatch reduction technology. Duke’s project seeks to reduce sea turtle bycatch in North Carolina.

California Moves to Ban Mile-Long Fishing Nets Blamed For Killing Whales, Sharks, Dolphins, and Other Sea Life

September 4, 2018 — Environmentalists scored a major victory in Sacramento Thursday after California lawmakers overwhelmingly voted to phase out the use of a controversial type of fishing gear known as drift gillnets: mile-long nets blamed for unintentionally killing thousands of sea creatures, including endangered animals.

Over the past 28 years, drift gillnets have entangled and killed an estimated 4,000 dolphins, 456 whales and 136 sea turtles, according to government data obtained from the National Oceanic and Atmospheric Organization. The federal agency, which regulates the fishing gear, randomly places observers on about 20 percent of all fishing trips that utilize the gear in an effort to document the environmental impact.

California fishermen view the ban as extreme and unnecessary, and believe their livelihood is being unfairly targeted. Without the fishing gear, they fear they won’t be able to continue making a living.

“I don’t know what I’d do,” said Mike Flynn, who has depended on drift gillnets to catch swordfish for the past 40 years. “There’s very few of us left, and we don’t seem to have a chance…we’re being villainized, unjustly.”

Only about 20 fisherman actively use the gear off the California coast; that’s down from 141 active permits at the peak back in 1990, according to NOAA.

Aquarium wins grant to test ropeless fishing gear

August 27, 2018 — The New England Aquarium has been awarded a $227,000 grant to test a ropeless fishing prototype to eliminate large whale entanglements in pot fishing gear, National Oceanic and Atmospheric Administration Fisheries announced.

The federal agency awarded more than $2.3 million to 14 groups to support bycatch reduction research projects. Bycatch includes fish, marine mammals and turtles in this program, which intends to work side-by-side with fishermen on their boats to develop solutions to some of the top bycatch challenges in the country, the agency said in its announcement.

“U.S. pot fisheries that target crustaceans are popular in New England, and are important economically and culturally,” according to the aquarium’s description of its project. “However, the critically endangered North Atlantic right whale, and other large species of whale and protected species can become entangled in the ropes used in pot fisheries.”

“Ropeless fishing” involves securing ropes to the seafloor where traps are being fished, and when the trap is ready to be hauled to check for catch, ropes are released to the surface by an acoustically triggered device, according to the aquarium.

In mid-July, the International Fund for Animal Welfare also funded a $30,000 test with Sandwich lobsterman David Casoni of one type of ropeless technology — an acoustic release system by Desert Star Systems — in cooperation with the Massachusetts Lobstermen’s Association.

MARK HELVEY: Protect California’s Drift Gillnet Fishery

August 24, 2018 — WASHINGTON — California’s drift gillnet (DGN) fishery has come under attack in recent months. One of the most prominent media attacks was a July Los Angeles Times editorial “Dead dolphins, whales and sea turtles aren’t acceptable collateral damage for swordfishing,” which irresponsibly called for the shut down of the fishery. Like many similar critiques, it overlooked the ways DGN fishermen have worked to reduce bycatch and the unintended consequences of shutting down the fishery.

It is first important to note that the DGN fishery operates legally subject to all bycatch minimization requirements in federal law. This includes not just the Magnuson-Stevens Act—the primary federal fishing law—but also the Marine Mammal Protection Act and the Endangered Species Act (ESA). These statutes are precautionary and conservation-minded, and help make U.S. fisheries some of the most environmentally conscious and best managed in the world.

DGN fishermen have collaborated extensively with NOAA’s National Marine Fisheries Service over the years to further reduce bycatch. Since 1990, the fishery has operated an observer program to effectively monitor bycatch. It has deployed devices such as acoustic pingers to ward off marine mammals from fishing gear, has established the Pacific Offshore Cetacean Take Reduction Plan to further reduce marine mammal interactions, and has implemented time/area closures to reduce interactions with endangered sea turtles.

These measures have led to significant progress in reducing bycatch. For example, no ESA-listed marine mammals have been observed caught in the DGN fishery since the 2010-2011 fishing season and no listed sea turtles since the 2012-2013 season.

As mentioned in the Times editorial, there is indeed good news from fisheries deploying new, experimental deep-set buoy gear. But it is just that – experimental, and it is still unclear whether it will become economically viable. And while fishermen hope that it does, the volumes produced won’t make a dent in the over 80 percent of the 20,000 metric tons of swordfish consumed annually in the U.S. that comes from foreign fisheries.

Often missing from the discussion of the drift gillnet fishery is that most foreign fisheries are far less regulated and are much more environmentally harmful than any U.S. fishery. Should the U.S. DGN fishery be shut down, it will only further increase our reliance on this imported seafood. All U.S. fishermen abide by the highest levels of environmental oversight relative to their foreign counterparts, meaning that U.S. caught seafood comes at a fraction of the ecosystem impacts occurring abroad.

Californians need to understand this and help protect U.S. fisheries that are striving to do things the right way. California’s DGN fishermen provide seafood consumers with a local source of sustainably-caught, premium quality swordfish. We should thank them by keeping them on the water.

Mark Helvey had a 30-year career with NOAA’s National Marine Fisheries Service (NMFS) before retiring in 2015.  He served as the last Assistant Regional Administrator for Sustainable Fisheries with the NMFS Southwest Region in Long Beach, representing the agency on fishery conservation and management for highly migratory and coastal pelagic species on the west coast.

 

Cool ocean temps, reduced salmon bycatch likely to boost Alaska groundfish catches

August 22, 2018 — Reduced salmon bycatch and increased catches of rockfish bode well for Alaska’s groundfish trawlers in 2018. As of July, most of the boats had off-loaded their dragging gear and switched over to massive deck pumps to fill out salmon tendering contracts in Bristol Bay and elsewhere around the state.

That’s typical for many of the Kodiak-based catcher boats in the off-season, but the kicker in their year (so far) began during fisheries directed for arrowtooth flounder and various rockfish species months earlier.

“Things have been off in recent years, in the way that the fisheries have been functioning,” said Julie Bonney, executive director of the Alaska Groundfish Data Bank, in Kodiak.

Incidental catches of king salmon and halibut during the 2017 season caused closures that not only put a crimp in the potential harvest of the groundfish quotas but caused an unfavorable pulse of supplies in markets that favor a steady flow of fish to end consumers.

But 2018 brings hope of a turnaround. Ocean conditions seem to have gifted the trawlers in terms of distribution and density of rockfish. As of July 1, the fleet had harvested 68 percent of the rockfish quota compared to 2017 when they caught 43 percent.

Better yet, the incidental take of king salmon was down. Bonney reported on June 28 that the fleet in the Gulf of Alaska logged 6,200 salmon of a total allowable 32,250 salmon.

Models may help reduce bycatch from longline fishing

August 10, 2018 — Hundreds of thousands of sharks, sea birds and other marine species are accidentally killed each year after they become snagged or entangled in longline fishing gear.

New models developed by a Duke University-led team may help reduce this threat by giving regulatory agencies a powerful new tool to predict the month-by-month movements of longline fishing fleets on the high seas. The predictions should help determine where and when the boats will enter waters where by-catch risks are greatest.

“By comparing our models with data showing where by-catch species are likely to be each month, ship captains, national agencies and regional fisheries management organizations can pinpoint potential hotspots they may want to temporarily avoid or place off-limits,” said Guillermo Ortuño Crespo, a doctoral candidate in the Marine Geospatial Ecology Lab at Duke’s Nicholas School of the Environment.

“This represents a movement away from a reactive approach to fisheries management — where we only know about problems as or after they occur — to a more proactive approach that helps us stay one step ahead of the game,” he said.

Ortuño Crespo and his colleagues describe their new models in a peer-reviewed paper August 8 in Science Advances.

To devise the models, they collaborated with Global Fishing Watch to collect geospatial information from individual boats’ automatic identification system (AIS) signals. AIS data shows the movements and distribution of longline fishing fleets operating in the high seas in 2015 and 2016.

Then they statistically correlated each ship’s fishing efforts to 14 environmental variables — such as sea surface temperatures or distance to the nearest seamount — that influence a region’s seasonal suitability as a habitat for species targeted by longliners. This allowed them to create highly accurate models that predict where the fishing fleets will be each month of the year.

The new models track data for fleets from Japan, South Korea, Taiwan, China and Spain, which accounts for most of the longline fishing currently taking place in the open ocean beyond national jurisdictions. Future models could include fleets from other nations and offer expanded functionality that will allow regulatory agencies to view the data within a global context or break it down by individual nation, region or fleet.

Slump in global squid catch ignites fisheries management efforts

July 12, 2018 — A global slump in the catch of squid — that has caused alarm bells as prices for key commercial species rocket — is bringing some of the biggest industry players together in an effort to improve squid fisheries management. But significant obstacles stand in their way, with China’s role front and center.

In recent years squid has become an increasingly important commercial species. According to the Food and Agriculture Organization of the United Nations (FAO), global squid catch has increased from 3.09 million metric tons in 2000, to 3.95m metric tons in 2015.

Squid previously discarded as worthless bycatch is now the target of international fleets.

But in 2016, global catch fell by over a million metric tons, to 2.79m metric tons (see graph below). Prices of Argentine shortfin squid, a key benchmark, have more than doubled. This season’s Argentine squid catch in international waters is said to be half last year’s levels, or worse.

Speaking to Undercurrent News, Sam Grimley, director of strategic initiatives at Sustainable Fisheries Partnership (SFP), an NGO, said concerns have mobilized industry stakeholders to come together to find solutions. Today, several fisheries improvement projects (FIP) are now underway or in the pipeline; five years ago, bar a couple in North America, there were none.

New oceanographic insight pinpoints marine ‘hotspots of risk’

June 27, 2018 — Increased computing power has given fisheries researchers new tools to identify “hotspots of risk,” where ocean fronts and eddies bring together masses of fish, fishermen and predators, raising the risk of entangling non-target fish and protected species such marine mammals, sea turtles and sharks.

Using a novel, high-resolution “Lagrangian Coherent Structures” mapping technique, scientists are able to model dynamic features in surface currents. The capacity for improved, near real-time mapping of and eddies may now help alert fishermen and fisheries managers to the increased risk so they can try to avoid those protected species and better target the species they are after, the scientists wrote in an article published today in Proceedings of the National Academy of Sciences.

“Understanding how pelagic fish and marine predators interact with the environment can help fishers and managers avoid bycatch of non-target and protected species, while maintaining the catch of commercial species,” said Kylie L. Scales of the University of the Sunshine Coast (USC) in Australia, and lead author of the new research. “Our findings give managers information at the broad scales they need, which could help inform development of dynamic ocean management.”

Lagrangian Coherent Structures are known from the field of fluid dynamics and represent areas of mixing, where different water masses meet and tend to concentrate marine life and in turn fishermen. The new approach uses high-resolution ocean modeling to help detect and predict the areas as they form and move through the ocean, and highlight the elevated risk they may present.
