CALIFORNIA: Commercial crabbers worry bringing sea otters back to San Francisco Bay could hurt industry

August 26, 2023 — There is a push by conservationists to reintroduce threatened sea otters to San Francisco Bay waters, but local crab fishermen are concerned the move could hurt their already struggling industry.

Federal wildlife officials say it’s possible, but haven’t made a decision whether to green light the move. Those efforts worry fishermen like Dick Ogg because of the sea mammals’ voracious appetite for crustaceans like Dungeness crab.

“I don’t feel like it’s our place to pick them up and relocate them. Yes, there could be impacts to the fishery,” said Ogg.

The fur trade era in the 19th century nearly wiped out the now-endangered species. Marine biologists are trying to determine what’s best for conservation, fisheries like the Dungeness crab industry and the marine environment.

“Sea otters tend to promote the resilience of kelp and sea grass. And those habitats provide habitat and food for hundreds upon hundreds of species,” explained U.S. Fish and Wildlife Service biologist Lilian Carswell, who specializes in sea otters.

EDITORIAL: U.S. Fish and Wildlife Service Strategy to Reintroduce Sea Otters is Flawed

August 12, 2022 — The USFWS study fails to estimate costs to taxpayers; impacts to key local fisheries such as Dungeness crab and sea urchin; neglects to fully examine the impacts to local port and harbor activities and fishing communities and fails to directly clarify to impacted Tribal Nations that no ceremonial and subsistence uses – or control of otter populations negatively impacting other important Tribal resources – are permitted under current Federal law.

For Oregon and California coastal communities dependent on Dungeness crab, sea urchin, and other shellfish, reintroducing sea otters in an area where they have been absent for more than 100 years will spell big trouble. Yet, a recent report from the U.S. Fish and Wildlife Service (USFWS) concludes it is “feasible” to reintroduce them to Southern Oregon and Northern California. In June 2022, the USFWS report, Feasibility Assessment: Sea Otter Reintroduction to the Pacific Coast, was released in response to a largely-unvetted Congressional mandate. In this report, the Agency lays out the potential benefits of reintroducing sea otters to new areas of the West Coast. It identifies some – but not all – significant areas of concern.

When plentiful, shellfish and crabs account for a most of a sea otter’s diet. Their voracious feeding activity, especially related to the almost certain impacts to the West Coast heritage Dungeness crab fishery and sea urchin harvests, alarms West Coast fishermen and processors. Otters eat 23% to 33% of their body weight daily. Just 169 otters weighing an average of 50 pounds each, feeding full time on urchins, would consume an amount equal to the entire annual commercial catch, making a commercial fishery not viable. Dungeness crabs are caught near small ports from Oregon to Central California, and the sea urchin fishery operates in Oregon and California.

Bringing sea otters back to Oregon faces ideological challenges

August 9, 2022 — If asked to choose between the environment and commercial interests, most environmentalists would naturally side with the former. But the reality is more complicated, particularly when Indigenous tribes — long left out of the conversation on how the federal government navigates issues concerning natural resources and commercial interests — are brought to the table.

In the case of mitigating climate change by reintroducing sea otters to habitats where they once thrived, the U.S. Fish and Wildlife is faced with such a dilemma. Particularly so because bringing sea otters to the Northern California and Oregon coasts sounds promising to everyone except those who are already living near the endangered species.

Known by some local tribes as the Elekha, sea otters are a small marine mammal of the family Mustelidae, characterized by their furry, weasel appearance and their hallmark tendency to float on their back while using a rock to open hard-shelled invertebrates. The animal is objectively cute, with its furry white face that pops over the top of the ocean to stare out like a teddy bear with tiny eyes and an extra wide nose.

The southern and northern sea otters, Enhydra lutris, are distinct by geography and marginally by their DNA, as fur traders nearly hunted the animal to extinction during the 18th and 19th centuries. Southern sea otters live in small pockets along the Southern California coastline while northern sea otters live from northern Washington state to southeastern Alaska — the latter a direct result of preservation and reintroduction.

US West Coast seafood groups concerned about potential reintroduction of sea otters

June 17, 2022 — A plan by the U.S. Fish and Wildlife Service (USFWS) to reintroduce sea otters to the West Coast of the U.S. is continuing to draw concern from fishing industry advocates.

The USFWS has had plans to reintroduce wild sea otters to habitats in the Northwest U.S. for years. A bill signed in 2020 by former U.S. President Donald Trump ordered a review of the potential impacts the reintroduction could have on the region – and in 2021, the industry requested a thorough review of how it might impact fisheries and coastal economies.

The Americas’ First Ecosystem Managers

August 19, 2021 — The maritime fur trade, beginning in the 1700s and centered on the North Pacific Ocean, killed around one million sea otters and left the species fluttering on the verge of extinction with a global population as low as 1,000. On the west coast of Canada, the animal didn’t make it. The last sea otter was seen in the region in 1929, off Vancouver Island, British Columbia. But beginning in the 1960s, restoration efforts have turned back the clock on British Columbia’s sea otters. From an initial 89 sea otters relocated from Alaska, a population of 8,000 is now expanding in the province. Yet after generations of their absence, the surge in sea otters is stoking the resentment of some residents.

The trouble is, a sea otter consumes 25 to 30 percent of its own body weight every day. The otters’ voracious appetite can have dramatic ecological effects. It doesn’t help, either, that sea otters eat many of the same seafoods that humans in the area have long favored, such as crabs and clams, sparking conflict with shellfish fisheries and leading some to argue that the reintroduction effort has worked too well.

Now, a new study suggests that conservation efforts may have indeed overshot the mark—and the reason why is particularly interesting.

When thinking about restoring natural ecosystems, the goal for many would likely be to see a species rebound to its carrying capacity—that is, the maximum population a given habitat can support, free from human impact. So, for the sea otter, that would be to roll back the effects of colonization, the commercial fur trade, hunting, land development, and other pressures to a time when abundant sea otters may have dwelled on the coast, gorging on abalone and other shellfish. But taking that as your goal is to overlook the way Indigenous peoples extensively managed the sea otter population for thousands of years.

Led by Erin Slade, a graduate student at British Columbia’s Simon Fraser University, new research examining the sizes of mussels found along the coast challenges the assumption that late-Holocene sea otter populations would have ever been at, or even near, their carrying capacity.

US West Coast fishing industry requests review of sea otter reintroduction

August 16, 2021 — Major players in the U.S. West Coast fishing industry sent a letter to the U.S. Fish and Wildlife Service (USFWS) on Thursday, 12 August, requesting a thorough review of how a proposed sea otter reintroduction might affect the region’s fisheries and coastal economies.

A bill signed last year by former U.S. President Donald Trump gave USFWS until the end of 2021 to assess the impact a West Coast sea otter reintroduction might have on the region.

Skeptics of sea otter reintroduction getting organized on Pacific Coast

August 13, 2021 — Sea otters are undeniably cute, but cuteness only goes so far when major economic interests are at stake. That’s an inference you can make from the emergence of organized pushback to the possible reintroduction of sea otters along the Oregon Coast.

A trade group, the West Coast Seafood Processors Association, enlisted 24 maritime interests to sign on to a letter expressing grave concerns about bringing back sea otters. Some of the signatories include the ports of Ilwaco, Astoria, Newport, Coos Bay and Brookings, the Pacific Coast Shellfish Growers and Columbia River crab fishermen.

“We’re hoping to get ahead of the curve here and get something on the record,” said Lori Steele, executive director of the Portland-based WCSPA.

In the letter sent to the U.S. Fish and Wildlife Service last week, the skeptics said the voracious appetite of sea otters would put the furry animals in conflict with fishermen and shellfish harvesters. The letter also raised red flags about the prospect of permitting difficulties for port projects, dredging and offshore wind farms if another protected marine mammal species were present.

“Our message to the U.S. Fish and Wildlife Service is really, proceed with caution and be extremely thoughtful about potential impacts of this before doing anything,” Steele told the Port of Astoria Commission during its most recent meeting.

Pacific sea otter reintroduction gets nudge from Congress

January 8, 2021 — President Donald Trump on Wednesday signed this year’s federal budget, which includes a directive to study sea otter reintroduction in the Pacific Northwest.

Democratic U.S. Sen. Jeff Merkley for Oregon added the paragraph to the federal budget bill that directs the U.S. Fish and Wildlife Service to study the feasibility and cost of reestablishing the marine mammals where they were once hunted to near-extinction along the Pacific coast in Oregon and Washington, the Northwest News Network reported.

“I’m very pleased. This is very timely,” said Bob Bailey, who leads the Elakha Alliance, a group that wants to bring wild sea otters back to Oregon. His organization, named after the Clatsop-Chinookan word for sea otter, prompted congressional action and already launched its own feasibility study based in Oregon.

Sea Otters Could Get New Home in San Francisco Bay

December 29, 2020 — Once hunted to the brink of extinction for their luxuriant pelts, California sea otters rebounded after protections were put in place in 1911. Their population grew steadily for much of the last century, but now the still threatened species is stuck at about 3,000 otters. The problem is that they are boxed in at both ends of their current range, along the state’s central coast, by a sharp (and so far unexplained) rise in shark attacks. Hoping to reintroduce breeding populations elsewhere in the otters’ historical range, wildlife managers have been looking at certain coastal estuaries, which are sheltered pockets of water.

It turns out that the largest estuary on the West Coast—San Francisco Bay—could potentially provide an excellent home for sea otters, despite being in the middle of a major urban area, according to a study published last month in PeerJ.

“I was surprised,” says lead study author Jane Rudebusch, a spatial ecologist at San Francisco State University’s Estuary & Ocean Science Center. “The bay is intensely urbanized. You can tell it’s a busy place just by looking at it.” Tanker ships deliver crude oil to shoreline refineries every day, and high-speed commuter ferries constantly zoom between San Francisco, Oakland and other waterfront cities at up to 50 miles per hour. Sediment in parts of the bay is laced with methylmercury and polychlorinated biphenyls, toxic chemicals that accumulate in the clams, crabs and other animals that sea otters eat.

Are sea otters taking a bite out of California’s Dungeness crab season?

December 15, 2020 — Dungeness crabs are a holiday tradition every year on tables across Northern California. But the prized crustaceans also are a prime delicacy for other local residents — sea otters that live along the Central Coast.

Scientists are studying whether to relocate sea otters north into San Francisco Bay to help expand their population back to its historic range. But fishermen have been wary, concerned that the otters could reduce the number of Dungeness crabs, a $51 million industry, and one of California’s largest commercial fisheries.

Now a new study suggests the two beloved ocean luminaries may be able to co-exist. In a paper published Thursday, researchers from Duke University, the Monterey Bay Aquarium and the U.S. Geological Survey found that as the number of sea otters has grown off central California in recent decades, the catch of Dungeness crabs by fishermen in Half Moon Bay, Monterey and Morro Bay actually also has gone up, not down.

The study could increase the chances that otters will be reintroduced into San Francisco Bay nearly 200 years after they were last seen there, or to other places north of the Golden Gate Bridge.
