Fishermen and Scientists Pioneer Cooperative Rockfish Survey

July 15, 2020 — The following was released by NOAA Fisheries:

When Gulf of Alaska rockfish fishermen approached NOAA Fisheries biologist Mark Zimmermann with an innovative proposal, he saw a potential solution to a rocky problem.

“They offered to collect scientific data in ‘untrawlable’ areas where standard NOAA Fisheries survey trawls can’t sample fish populations. I was impressed with the advanced technology that they use to fish in these rocky, steep habitats, like a live-feed video camera that helps them target their catch while minimizing gear and habitat damage,” Zimmermann said. “I was also impressed that they wanted to use these capabilities to improve rockfish assessments. This fishery is really important to them, and they want to invest in the resource by providing us scientific data to manage it. They want to help ensure that annual catch limits are sustainable.”

That conversation spawned a cooperative pilot study to explore the possibility of using industry catch and effort data to inform Gulf of Alaska rockfish assessments. The new project is called the Science-Industry Rockfish Research Collaboration in Alaska.

“Rockfish fishermen are taking a long-term stake in conservation,” said  John Gauvin, science projects director at Alaska Seafood Cooperative (offshore harvest cooperative). “The industry has made large investments to improve fishing practices. We hope some of those innovative fishing practices will provide data for this cooperative effort to improve rockfish stock assessments in the Gulf of Alaska. We expect this will take a strong partnership between industry and scientists, and we are fully on board with that. We are ready to make the necessary investment in time and resources to make it successful.”

Study: Bay Rockfish Die at Twice the Rate of Those in Atlantic

May 18, 2020 — Striped bass that stay year-round in the Chesapeake Bay are dying at nearly twice the rate of those that migrate each year to the Atlantic Ocean, a new study has found. The cause or causes aren’t clear, but the lead researcher said that it needs to be addressed to right a troubling decline in the prized finfish.

An electronic tagging study led by scientists from the University of Maryland Center for Environmental Science found that large mature striped bass leave the Bay every year to roam coastal waters until the next spring. Those smaller, younger fish that remain in the Chesapeake died off at the rate of 70% a year.

“The mortality rate is alarming,” said Dave Secor, a professor at the UMCES Chesapeake Biological Laboratory in Solomons. “If fish are dying at greater than 50% or 60% a year, that’s a problem.”

The study, published Thursday in the journal PLOS One, appears likely to draw further attention to disease and overfishing, two suspects in the decline of striped bass, also known as rockfish, which are among the most sought-after fish in the Chesapeake and along the Atlantic coast.

UMCES scientists implanted acoustic transmitters in 100 striped bass from the Potomac River and tracked their movements over four years. Signals emitted by their tags were picked up as they swam by receivers stationed in the Bay and along the coast — a kind of E-Z Pass network for fish, as Secor described it.

Large rockfish leave Chesapeake Bay to become ocean migrators

May 15, 2020 — A new electronic tagging study of 100 Potomac River striped bass sheds light on rockfish migration in Chesapeake Bay and the Atlantic Coast. University of Maryland Center for Environmental Science researchers found that when rockfish reach 32 inches in length they leave Chesapeake Bay and become ocean migrators. Small fish stayed in the Bay had higher mortality rates than those that undertook ocean migrations.

“Knowing the size at which they leave, we can do improved management that is tailored better to commercial and  sectors those related to catch and size limits,” said study author and Professor Dave Secor of the University of Maryland Center for Environmental Science. “It allows us to bring different parts of the fishery into an assessment model to evaluate stock health and test how effective regulations will be.”

Chesapeake Bay striped , also known as rockfish, (Morone saxatilis) were implanted with two-inch acoustic transmitters and their coastal shelf migrations recorded over a four-year period by telemetry receivers throughout the Mid-Atlantic shelf waters and southern New England. Researchers found that only large striped bass from the Chesapeake Bay migrate to ocean waters when they reach 32 inches in length, and smaller fish remain resident to the Chesapeake Bay, regardless of sex.

California’s offshore oil platforms, now marine hotspots, face removal

April 7, 2020 — Tens of thousands – hundreds of thousands, even – of rockfish, boccaccio, and lingcod congregate around the pillars of Southern California’s 27 offshore oil platforms, while shellfish cling to them in thick mats.

The platforms near the Channel Islands are among the world’s most productive hotspots for marine life, producing 27 times more total fish biomass than nearby natural rocky reefs, according to scientists, with rockfish making up 90 percent. From the surface, the platforms descend between 100 to 1,200 feet to the ocean floor; the height of the tallest is comparable to the Empire State Building.

Fisheries of the U.S. 2018 Report: West Coast, Hawaii Generally Stable with a Few Exceptions

February 26, 2020 — Rockfish landings and values are up, squid landings are down on the West Coast. Sablefish prices have dropped, following an increase in landings on the West Coast and Alaska. Hawaii’s total value for seafood products is up, even though lower volumes of fish are being harvested.

Such are just some of the data included for the Pacific Coast in NMFS’ Fisheries of the United States, 2018, report that was released Friday. The report combines data from Alaska and the West Coast—and sometimes Hawaii, too—into the larger Pacific Coast, but a few of the tables and information reveal clues that tell their own stories or trends specific to smaller areas or individual fisheries.

West Coast fishery rebounds in rare conservation ‘home run’

December 26, 2019 — A rare environmental success story is unfolding in waters off the U.S. West Coast.

After years of fear and uncertainty, bottom trawler fishermen ” those who use nets to catch rockfish, bocaccio, sole, Pacific Ocean perch and other deep-dwelling fish ” are making a comeback here, reinventing themselves as a sustainable industry less than two decades after authorities closed huge stretches of the Pacific Ocean because of the species’ depletion.

The ban devastated fishermen, but on Jan. 1, regulators will reopen an area roughly three times the size of Rhode Island off Oregon and California to groundfish bottom trawling ” all with the approval of environmental groups that were once the industry’s biggest foes.

The rapid turnaround is made even more unique by the collaboration between the fishermen and environmentalists who spent years refining a long-term fishing plan that will continue to resuscitate the groundfish industry while permanently protecting thousands of square miles of reefs and coral beds that benefit the overfished species.

Now, the fishermen who see their livelihood returning must solve another piece of the puzzle: drumming up consumer demand for fish that haven’t been in grocery stores or on menus for a generation.

‘It’s really a conservation home run,’ said Shems Jud, regional director for the Environmental Defense Fund’s ocean program. ’The recovery is decades ahead of schedule. It’s the biggest environmental story that no one knows about.”

The process also netted a win for conservationists concerned about the future of extreme deepwater habitats where bottom trawlers currently don’t go. A tract of ocean the size of New Mexico with waters up to 2.1 miles (3.4 kilometers) deep will be off-limits to bottom-trawling to protect deep-sea corals and sponges just now being discovered.

‘Not all fishermen are rapers of the environment. When you hear the word ‘trawler,’ very often that’s associated with destruction of the sea and pillaging,” said Kevin Dunn, whose trawler Iron Lady was featured in a Whole Foods television commercial about sustainable fishing.

Latest regulations safeguard 140,000 square miles off the West Coast

November 19, 2019 — Monday, the National Oceanic and Atmospheric Administration (NOAA) issued final regulations to protect the seafloor habitat off the West Coast from bottom trawling.

The regulations cover 140,000 square miles and includes corals, sponges, rocky reefs and other important areas for marine life and ocean ecosystems. These safeguards for the living seafloor are in response to a vote by the Pacific Fishery Management Council in April 2018, which followed years of scientific input and advocacy by Oceana, which has an office in Monterey County.

Bottom trawling is described as the most damaging fishing method to seafloor habitats off the West Coast. Weighted nets are dragged to catch fish living near the seafloor and in doing so flatten, topple and crush delicate corals and sponges that provide habitat for these fish and other marine creatures.

The new regulations protect unique and important ocean areas off Washington, Oregon and California. Also included is the protection of deep-sea habitats beyond 3,500 meters depth (nearly 2 miles) below the ocean’s surface from all commercial bottom-contact fishing gear. In addition, the regulations increase fishing opportunities by allowing select re-openings in some historic fishing grounds where bottom trawling has been prohibited in recent years to recover overfished rockfish populations.

Bottom-trawling fishing severely restricted off West Coast starting in January

November 19, 2019 — The most extensive ban on bottom trawling — dragging weighted nets on the sea floor — became law Tuesday after fishing groups and environmentalists agreed to protect more than 140,000 square miles of seafloor habitat along the West Coast, including beds of lush coral around the Farallon Islands.

The new regulations, which will take effect Jan. 1 after being published in the Federal Register on Tuesday, will restrict fishing over 90% of the seafloor along the coast from Canada to Mexico, the largest contiguous area protected from bottom trawling in the world.

At the same time, about 3,000 square miles of sandy seafloor previously closed to fishing under the 2002 Rockfish Conservation Area rules were reopened after it was determined that rockfish populations had recovered in those areas.

“It’s monumental,” said Geoffrey Shester, the senior scientist for the conservation group Oceana, which has fought for years to limit bottom trawling, long considered the most damaging method of fishing in the ocean. “It puts the West Coast at the top of the barrel for global leadership in protecting our seafloor.”

West Coast Fisheries “Comeback of the Century”

October 8, 2019 — The following was released by NOAA Fisheries:

With help from rebounding West Coast rockfish, Giuseppe “Joe” Pennisi has put the fisherman back in San Francisco’s famed Fisherman’s Wharf.

Pennisi is the first fisherman to sell freshly caught fish off his boat at Fisherman’s Wharf in many years. He has reintroduced locals to the flaky white fish that was once a mainstay of West Coast seafood. Most weekends when the fishing is good, crowds form early at the dock next to his boat, the Pioneer, and continue all day. Some wait for hours to buy chilipepper rockfish, rose fish, boccacio and other deep-water species Pennisi brings up in his nets.

“You can’t help but be excited when you get to the dock and all these people are waiting for their fish,” he said.

The reemerging demand for rockfish reflects what may be the West Coast fisheries comeback of the century. Rapidly rebuilding stocks are reviving opportunities for determined fishermen such as Pennisi and customers of his Pioneer Seafoods. From Washington to California, a fishing fleet that sacrificed heavily while groundfish stocks rebuilt are now beginning to harvest the results.

“It really does seem like we’re turning an important corner,” said Shems Jud, who has long tracked the groundfish fishery for the Environmental Defense Fund. The rebuilding of groundfish represents a rarity among environmental issues. Fishermen, environmental groups, fisheries managers, and others replaced contention and controversy with lasting collaboration.
