Big sea, bigger data: How analytics are making peace between fishermen and turtles

February 5, 2019 — The ocean is complicated. Our tools to manage it are blunt.

We often approach the ever-changing ocean as if it were a stationary valley in a national park. We close entire coastlines and restrict fisheries to protect single species. We’re flummoxed by wide-ranging mobile marine life and unprepared for climate change.

But a new generation of data-driven tools balances the needs of fish and fishermen and adapts automatically as the environment changes.

With the government’s towering stockpiles of ocean data, scientists can use weather and ocean chemistry to predict where fishermen are likely to catch their intended targets, including swordfish or tuna, and avoid protected species, such as marine mammals, sharks or manta rays.

Google and Facebook analyze data to predict our behavior with unnerving precision. With dynamic ocean management, scientists use similar strategies to protect the areas where turtles, albatross or whales are most likely to congregate in a given day or hour.

California wildlife agency denied in bid to delay lawsuit over whale, sea turtle entanglements

February 5, 2019 — A San Francisco judge has rejected the California Department of Fish and Wildlife’s bid to delay a lawsuit that claims the agency has fallen short in preventing the state’s commercial Dungeness crab fishery from entangling whales and sea turtles.

U.S. District Court Judge Maxine Chesney, on Jan. 25, denied the department’s motion to delay the case by 2 1/2 years while it secures a federal “incidental take permit” that would allow the agency to operate in a way that addresses and minimizes the threat to whales and sea turtles, while acknowledging some risk.

The Center for Biological Diversity sued Fish and Wildlife in October 2017 after the total number of whale entanglements from all fishing industries broke records for three straight years.

“The Dungeness crab fishery is the biggest entanglement culprit in California, by far,” said Steve Jones, a spokesman for the center. “Most entangling gear can’t be identified, but of the identified gear, it is mostly crab lines.”

IPHC agrees on halibut catch limit after 2018 impasse

February 4, 2019 — The International Pacific Halibut Commission (IPHC) has set 2019 catch limits slightly higher than last year’s levels, it announced.

The body, which sets halibut catch limits in the US and Canada, set the 2019 limit at 38.61 million pounds (17,513 metric tons) for the 2019 season, which should March 15 and must cease on Nov. 14.

In 2018, the IPHC was not able to agree on a catch limit. In a move called both “inevitable” and “disastrous”, the IPHC could not come to an agreement on the catch limits for the seasons in the US, off the coast of Alaska, Washington, Oregon, and California, and British Columbia, Canada. So, the US and Canada set limits independently, which totaled 37.2m lbs, a 9% decrease overall.

California has a weird new desert. It’s in the Pacific Ocean.

February 4, 2019 — Six years after it was stricken by a wasting disease off the northern California coast, the sunflower sea star — one of the most colorful starfish in the ocean — has all but vanished, and the domino effect threatens to unravel an entire marine ecosystem.

The cause of the sea star’s demise is a mystery, but it coincided with a warming event in the Pacific Ocean, possibly tied to the climate, that lasted for two years ending in 2015. It heated vast stretches of water in patches, and likely exacerbated the disease, according to a new study released Wednesday.

“I’ve never seen a decline of this magnitude of a species so important,” Drew Harvell, the lead author of the study, published in the journal Science Advances, that documented the sunflower sea star’s retreat into possible extinction off California and Oregon.

If the study had a purpose, she said, it was to call attention to the sea star’s demise so that federal officials would take action to list it as endangered and work to save it, possibly with a breeding program using sunflower stars that are surviving in parts of Washington, Alaska and Canada.

While global tilapia production increases, US imports fall

February 4, 2019 — Tilapia production globally has steadily increased over the past decade – with 2018 production estimated at nearly 6.3 million metric tons (MT) – yet U.S. imports were forecast to likely be at their lowest level in several years.

The data, shared at the Value Finfish panel during the 2019 Global Seafood Market Conference in Coronado, California earlier this month, estimates that the U.S. imported around 300,000 MT of tilapia in 2018. That’s significantly lower than the 500,000 MT high in 2012.

“Through October, through 2014, things have been on a pretty steady decline,” Todd Clark of Endeavor Seafood said.

The declines are clear in U.S. broadline sales, with virtually every commercial category having a steady three-year decline in sales. Commercial medium chains, representing chains with between 100 and 249 units, fell the most with a 46 percent drop in sales. Non-commercial restaurants, which make up the largest share of tilapia purchasing at over 14 million pounds, dropped six percent.

“Each one of those categories has been on a steady decline,” Clark said.

Ocean heat waves like the Pacific’s deadly ‘Blob’ could become the new normal

February 1, 2019 — When marine biologist Steve Barbeaux first saw the data in late 2017, he thought it was the result of a computer glitch. How else could more than 100 million Pacific cod suddenly vanish from the waters off of southern Alaska?

Within hours, however, Barbeaux’s colleagues at the National Oceanic and Atmospheric Administration (NOAA) in Seattle, Washington, had confirmed the numbers. No glitch. The data, collected by research trawlers, indicated cod numbers had plunged by 70% in 2 years, essentially erasing a fishery worth $100 million annually. There was no evidence that the fish had simply moved elsewhere. And as the vast scale of the disappearance became clear, a prime suspect emerged: “The Blob.”

In late 2013, a huge patch of unusually warm ocean water, roughly one-third the size of the contiguous United States, formed in the Gulf of Alaska and began to spread. A few months later, Nick Bond, a climate scientist at the University of Washington in Seattle, dubbed it The Blob. The name, with its echo of a 1958 horror film about an alien life form that keeps growing as it consumes everything in its path, quickly caught on. By the summer of 2015, The Blob had more than doubled in size, stretching across more than 4 million square kilometers of ocean, from Mexico’s Baja California Peninsula to Alaska’s Aleutian Islands. Water temperatures reached 2.5°C above normal in many places.

Court Denies California’s Attempt to Delay Whale Entanglement Case

February 1, 2019 — SEAFOOD NEWS — A federal court has rejected the California Department of Fish and Wildlife’s bid to delay a lawsuit alleging it’s not doing enough to prevent its commercial Dungeness crab fishery from entangling whales and sea turtles in violation of the federal Endangered Species Act.

The Center for Biological Diversity sued the department in October 2017 after whale entanglement numbers broke records for three straight years.

“This is an important win in our fight to protect whales and sea turtles from suffering and dying in crabbing gear. It’s time for California regulators to stop delaying and take action,” Kristen Monsell, oceans legal director at the Center, said in a press release. “The court recognized that it can’t just sit on the sidelines while state officials have no plan to prevent entanglements. Talking and holding endless meetings isn’t enough.”

U.S. District Court Judge Maxine Chesney denied the department’s motion to stay the case for two and a half years while it applies for an ESA Section 10 federal permit, which would require preventive measures. California sent a letter to NOAA last year, indicating the agency’s plans to formally file for the permit.

In the meantime, California has taken steps to avoid whale entanglements. The Dungeness Crab Fishing Gear Working Group published a best practices guide for fishermen It also established the Risk Assessment and Mitigation Program (RAMP) to support the state in working collaboratively with experts (fishermen, researchers, NGOs, etc.) to identify and assess elevated levels of entanglement risk and determine the need for management options to reduce risk of entanglement. Working with federal scientists, the group also solicits periodic flyovers to find concentrations of gear and concentrations of whales. With that information, fishermen can voluntarily get their gear and/or try to avoid whale interactions.

The Pacific Coast Federation of Fishermen’s Associations filed as an intervenor in the lawsuit and continues to support the industry in its efforts to avoid whale entanglement.

“No commercial fisherman wants to entangle whales or sea turtles in their fishing gear – doing so is not only a public relations disaster, but will likely destroy that gear, can damage their boats and can even be life-threatening,” the PCFFA states in its Memorandum in Support of Motion for Intervention in March 2018. “Many commercial fishermen voluntarily participate in programs to identify and rescue marine animals (especially whales) from entanglements in commercial fishing gear, often at great personal peril.”

On Feb. 22 the court is scheduled to consider the Center’s motion for summary judgment, the Center said in a press release.

In 2016 federal officials confirmed that the California commercial Dungeness crab fishery entangled at least 23 animals. As of late November, at least 36 whale entanglements had been reported off California in 2018, including at least five humpback whales entangled in California commercial Dungeness crab gear, the Center said in the statement.

California’s attention to this issue a few years ago has resulted in several gear workshops that included researchers, developers and fishermen coming together to try to solve or mitigate whale entanglement issues on the entire West Coast. Both Oregon and Washington now have their own gear/entanglement groups, working on problems and proposing incremental steps to prevent entanglements. Washington also has notified NOAA it intends to apply for an ESA Section 10 permit for its Dungeness crab fishery.

Killing Sea Lions to Save Salmon

January 31, 2019 — The following is excerpted from a story published today by The Atlantic:

Let us first establish that sea lions are supposed to live in the sea.

Since the 1990s, however, male sea lions—a handful at first, now dozens—have been captivated by the attractions of the Willamette River. They travel all the way from Southern California to Oregon and then swim up 100 miles of river to arrive at an expansive waterfall, the largest in the region. Here, salmon returning to spawn have to make an exhausting journey up the fish ladders of the Willamette Falls. And here, the sea lions have found a veritable feast.

“[They’re kind of sitting ducks,” the wildlife biologist Sheanna Steingass told me, describing the salmon. She paused to consider the metaphor. “Or sitting fish.” Every sea lion eats three to five fish a day.

In another world, this could just be a story about the intelligence of sea lions and their adaptability to river life. But in this world—where salmon populations throughout North America have plummeted, and where the winter steelhead run at Willamette Falls has fallen from 25,000 fish in the 1970s to just hundreds in 2018—it’s a dire story for the fish. After spending years trying and failing to deter the sea lions by nonlethal means, the Oregon Department of Fish and Wildlife, where Steingass leads the marine-mammal program, started “lethal removal” of sea lions in December. As of mid-January, they have trapped and euthanized five sea lions at Willamette Falls.

Killing animals to save other animals is always controversial. Animal-rights groups like the Humane Society of the United States denounced the sea-lion killings, calling them a distraction from the salmon’s real problems. And it’s true that a long chain of human actions—overfishing, destruction of salmon habitats, dams blocking their migration, hatchery mistakes—have led to what everyone can admit is this nonoptimal situation.

“In a perfect world, in an unaltered world, this wasn’t a problem, because historically there were 16 million salmon in the Columbia River,” says Doug Hatch, a senior fisheries scientist at the Columbia River Inter-Tribal Fish Commission. The sea lion’s appetites would have barely made a dent. It’s only because humans have so unbalanced the natural world that as drastic an action as culling sea lions could appear to be the fix.

Salmon-eating sea lions can now be killed legally

January 30, 2019 — Sea lions off the coast of California are being penalized for eating salmon — and it’s completely legal.

A new law allows for the killing of sea lions that have been feasting on the region’s endangered salmon, causing their numbers to drop. But hunters need to first get a permit.

The Endangered Salmon Predation Prevention Act was signed into law on Dec. 18, according to The National Oceanic and Atmospheric Administration.

“Many salmon and steelhead populations in the Northwest are threatened and endangered, and the last few years have been particularly hard as ocean conditions have turned and fewer salmon have returned to the rivers,” NOAA spokesman Michael Milstein told CNN.

Experts question value of “premium” seafood

January 30, 2019 — At the beginning of the panel on premium finfish at the 2019 Global Seafood Market Conference in Coronado, California, on 15 January, moderator Derek Figueroa, the chief operating officer of Denver, Colorado, U.S.A.-based Seattle Fish Company, flashed a slide with the definition of both “premium” and “premium seafood.”

  • Premium: Noun – a high-value or a value in excess of that normally or usually expected. Adjective – of exceptional quality or amount.
  • Premium seafood: Species or product form whose attributes drive product preference over and above the norm.

Figueroa clarified that the second definition had been created by the seven panelists themselves, and then, amidst updates on the status of species such as mahi, tilapia, sea bass, and barramundi, he curated a discussion on how the panelists arrived at their opinions on how they define “premium” seafood.

“What can we do to position seafood as a premium product?” Figueroa asked the panel. And, more provocatively, he added, “And do we want to?”

James Berger, the director of national sales for Jacksonville, Florida, U.S.A.-based Beaver Street Fisheries, seemed to struggle to answer Figueroa’s question.

“Is premium defined by price? Is it determined by the fact that you can’t find it – that it’s rare? Or is it defined by some stigma due to its cool Hawaiian name or that it comes from South America? I don’t know the answer,” he said.

Figueroa identified seven characteristics that can help define a species as premium: branding, price, sustainability, harvest method, country of origin, story/provenance, and whether it’s local or regional. He also pointed out the fact that harvesters, suppliers, retailers, and consumers each have their own distinct ideas of what defines a species of fish as premium. For harvesters, it could be demand, seasonality, and the labor involved. For suppliers, it could be harvest methods and availability. For restaurants or retailers, price, flavor, versatility, and sustainability play a role. For consumers, price and whether a fish is wild or farmed appear to be the main factors.
