Can salmon eat their way out of climate change?

December 12, 2019 — Warm waters are a threat to cold water fish like salmon and trout. But a study led by researchers at University of California, Davis suggests that habitats with abundant food sources may help buffer the effects of increasing water temperature.

The study, published in the Canadian Journal of Fisheries and Aquatic Sciences today, Dec. 10, shows that the availability of food in a natural system—not just stream  and flows—is an essential component of  habitat.

“In the future under climate change, productive ecosystems like spring-fed rivers, floodplains, estuaries and seasonal lagoons will be key links that give  like  and trout a leg up,” said lead author Robert Lusardi, a research ecologist and adjunct faculty at UC Davis and the California Trout Coldwater Fish Scientist.

For the experiment, researchers reared juvenile Coho salmon in a series of enclosures within the Shasta River basin, which is a tributary to the Klamath River. They examined how natural gradients in temperature and prey availability affected summer growth rates and survival.

West Coast Crab Managers Delay Primary Dungeness Season Again

December 10, 2019 — SEAFOOD NEWS — State fishery managers confirmed Friday the primary Dungeness crab season will be delayed until after Christmas in Washington, Oregon and California due to spotty meat quality. The delay will last until at least Dec. 31.

Some areas showed improvement in the last month to meet season-opening criteria of either 23 or 25 percent, depending on the area. However, too many areas in between the improved areas were still below the thresholds and managers decided to delay the season from the U.S./Canadian border to Point Arena, Calif., again to let the crab fill out more.

The third round of meat recovery testing will be conducted sometime in mid–December, targeting completion by Dec. 20. The results will determine if the season should open Dec. 31, be further delayed or be split into separate areas with different opening dates.

Industry members in all three states generally agreed with the decision, choosing to wait in the hopes the whole coast can open at once. The delay will also ensure consumers get the best and fullest crab available with the season does open.

But not everyone was happy with the decision. Some fishermen were counting on a big payday in December to cover bills. Other fishermen simply wanted to access full, healthy crab after seasons in which some ports had to wait while domoic acid levels dropped or the crab became fuller.

The Oregon Department of Fish and Wildlife said last year’s delayed crab season opening still brought in the second-highest ex-vessel value ever, $66.7 million, with 18.7 million pounds landed, just above the 10-year average.

In central California, crabbers are getting anxious to drop their gear. California Department of Fish and Wildlife Director Charlton Bonham in late November delayed the season until mid-December after a survey showed 49 humpback and four blue whales in the area. A subsequent survey on Dec. 3 showed four humpback whales and one blue whale present in the same survey area.

Endangered Winter-run Chinook Salmon Increase with Millions of Offspring Headed to Sea

December 9, 2019 — The following was released by NOAA Fisheries:

Biologists have estimated that almost 3.8 million juvenile winter-run Chinook salmon headed down the Sacramento River toward the ocean this year. This is the most offspring in a decade for the highly endangered population.

Typically about 80 percent of the outgoing juveniles have headed for the ocean by this time of year. This year’s total thus far is the most since 2009, when about 5 million juveniles traveled downriver.

The rebounding numbers of winter-run Chinook salmon reflect the critical help of a conservation fish hatchery and balanced water management. More favorable ocean conditions also benefited the parents of this year’s surging crop of juveniles, biologists say. About 8,000 adult fish returned to the Sacramento River to spawn earlier this year, the most since 2006.

“These fish continue to impress us with their resilience and their ability to survive if given the opportunity,” said Maria Rea, Assistant Regional Administrator for NOAA Fisheries’ California Central Valley Office. “By working cooperatively, we can make the best use of our suite of tools to protect and recover these endangered fish.”

Offshore wind still looks to get a foothold in California

December 9, 2019 — There may be a literal energy windfall off the coast of California but it is still unclear whether the federal government will give approval to specific sites and how long it will take before tall turbines are bobbing on the Pacific, sending electricity to customers across the Golden State.

Wind energy’s boosters are eager to see proposed projects get the go-ahead.

“Let’s get a couple of these rolling, get some floating offshore turbines out there and build this over time, which is exactly what you’re seeing on the East Coast,” said Tom Kiernan, CEO of the American Wind Energy Association.

For now, the state, local and federal governments are working with military brass to negotiate a possible agreement that could see a way clear for a pair of sites off the coast of Central California but a compromise thus far has proved elusive.

New regulations to expand protections for seafloor habitats, reopen fishing grounds off US West Coast

December 5, 2019 — New regulations for essential fish habitat off the West Coast of the United States that go into effect in 2020 will extend protections for deep-sea habitats and corals while reopening fishing grounds where fish populations have rebounded.

The new rules were finalized by the US National Oceanic and Atmospheric Administration’s (NOAA) National Marine Fisheries Service (known as NOAA Fisheries) last month, and will go into effect on January 1, 2020. The updated regulations were recommended to NOAA by the Pacific Fishery Management Council and enjoy broad support from the fishing industry and environmentalists alike. The changes will be implemented via an amendment to the Fishery Management Plan for groundfish off the US West Coast.

The Pacific Fishery Management Council is responsible for minimizing impacts of human activities on essential fish habitat (EFH), which are habitats deemed vital to maintaining sustainable fisheries. In 2005, the Council established area closures in groundfish habitat that limited the use of bottom trawling and other types of fishing gear that come into contact with the ocean floor.

According to NOAA Fisheries, groundfish fisheries contribute $569 million to household incomes in West Coast communities, from the state of Washington down to Southern California. About 3,000 square miles that had been closed to bottom trawling for groundfish will be reopened when the changes take effect, including 2,000 square miles of a Rockfish Conservation Area off the coasts of California and Oregon that have been off-limits to bottom trawling since 2002.

Fishing groups sue federal agencies over latest water plan for California

December 4, 2019 — The fracas over California’s scarce water supplies will tumble into a San Francisco courtroom after a lawsuit was filed this week claiming the federal government’s plan to loosen previous restrictions on water deliveries to farmers is a blueprint for wiping out fish.

Environmental and fishing groups sued the the National Marine Fisheries Service and U.S. Fish and Wildlife Service Monday for allegedly failing to protect chinook salmon, steelhead trout and delta smelt.

They believe the voluminous government proposal, known as a biological opinion, sacrifices protections for the imperiled fish without adequate justification so that Central Valley farmers and Southern California cities can have more water.

The lawsuit, filed in U.S. District Court in San Francisco, charges that the government’s plan to boost agricultural deliveries from the Sacramento-San Joaquin River Delta is an arbitrary and capricious failure to uphold the Endangered Species Act.

Bumble Bee’s Chris Lischewski convicted of fixing prices of canned tuna

December 4, 2019 — Christopher Lischewski, the former president and CEO of Bumble Bee Foods, was convicted on 3 December, 2019, of helping to orchestrate a price-fixing conspiracy between Bumble Bee, Chicken of the Sea, and StarKist, the so-called “Big Three” players in the U.S. canned tuna sector.

Lischewski was found guilty of one count of price-fixing by a jury in the U.S. District Court for the Northern District of California and faces up to 10 years in prison and a fine of USD 1 million (EUR 900,000). His sentencing has been set for 8 April, 2020. Lischewski’s conviction may also open him up as a target of civil lawsuits filed by parties who overpaid for canned tuna as a result of the price-fixing, according to Eric Snyder, chairman of the bankruptcy practice at Wilk Auslander, a New York City-based law firm.

New Crab Pot Could Help Reduce Whale Entanglements

December 2, 2019 — Oregon’s Dungeness crab season is coming up, but there’s a problem looming over this fishery.

The ropes and buoys that allow crabbers to collect their crab pots from the seafloor can injure and even kill whales when they swim into them.

Last year, 46 whale entanglements were reported off the West Coast, and crab gear was responsible for about a third of them.

According to Derek Orner, a bycatch reduction program coordinator with the National Marine Fisheries Service, this a growing problem in the spiny lobster and Dungeness crab fisheries.

“Were seeing increases in whale entanglements with a number of species that are listed under the National Marine Mammal Protection Act, in particular with humpback whales, gray whales, and blue whales,” he said.

His agency recently announced grants for several ropeless fishing gear projects, including a new kind of crab pot developed by Coastal Monitoring Associates of California.

Bart Chadwick, the company’s president, said when crabbers drop their pots in the ocean, the ropes and buoys can remain in the water column for days.

CALIFORNIA: The secret Richmond lab where Bay Area crab season annually learns its fate

November 29, 2019 — Each year, the fate of Northern California’s Dungeness crab season is in the hands of a few scientists in a quiet East Bay lab examining a small container of tan goo.

At the California Department of Public Health lab in Richmond, the goo is viscera, or the internal organs of a Dungeness crab, and the scientists study it to determine whether a neurotoxin called domoic acid is present.

While the commercial Dungeness crab season is on hold for an entirely different reason — a lawsuit over whale entanglements that postponed the season until Dec. 15 — three of the last four commercial Dungeness crab seasons were delayed after domoic acid, which is poisonous to humans, was found in local crustaceans. The neurotoxin can become present in crabs when algal blooms caused by rising ocean temperatures linger in local fishing waters during crab season. And with California crab fishermen capable of grossing $95 million a year during an uninterrupted season, domoic acid has resulted in tens of millions of dollars in lost revenue.
