If you like seafood, you’ve probably eaten Alaska pollock, the tender white fish used in most frozen fish sticks, McDonald’s Filet-O-Fish sandwiches, and the imitation crab meat found in California rolls. But the pollock – the world’s largest food fishery – is on the verge of collapse.

The most recent data from the National Marine Fisheries Service show the pollock population approaching the lowest level ever recorded; since 2003, the population has declined from 8.5 million tons to 3 million tons. That’s bad news for fish eaters and fishermen alike, and really bad news for Alaska’s extraordinary ocean ecosystem.

Even as the pollock – and the wildlife that rely on them – have declined, the government has allowed overfishing to continue.  Incredibly, these steep declines do not even meet the government’s definition of overfished.

As a result, two of Alaska’s four pollock fisheries have been closed and a third is just a fraction of its former size.  Until recently, though, the strength of the Bering Sea pollock stock was sufficient to support a billion dollar industry and earn a “sustainable” rating from the Marine Stewardship Council.

But like economics, fisheries management involves too many variables and too much uncertainty for anyone to make precise predictions.  And, as with the economy, when large amounts of money are at stake, managers tend to downplay that uncertainty and hope for the best.

That’s exactly what happened to the Atlantic cod, the pollock’s close relative, and the previous holder of the title “world’s biggest food fishery.” For years, the Atlantic fish industry refused to heed the warning signs that cod was in serious trouble, and tighter regulation was needed.

When policy makers did finally act, in 1992, it was too late – and the fishery crashed to less than one percent of its former level. By 1994, the fishery, which had been active since at least the beginning of the 16th century, had to be closed. Suddenly, more than 40,000 people were out of work and the industry went begging to the government for a multi-billion dollar bailout.

Today, the North Pacific Fisheries Council seems to be repeating the cod tragedy.

Despite the warning signs, including several years of low juvenile survivorship, the Council continues to allow trawlers to kill the fish that lay the golden eggs.  Each winter, factory trawlers brave the stormy Bering Sea to target spawning pollock, killing huge numbers of pregnant females before they release their eggs, or roe. The roe fishery is lucrative but ecologically dangerous even in the best of times. At a time when the pollock population needs all the offspring it can produce – and global warming seems to be putting additional stress on the fishery - it’s just reckless. The Council members (mostly representatives of the fishing industry) persist in saying that we can trust the industry to police itself – and are increasingly sounding like the Alan Greenspans of the sea.

It's still theoretically possible that environmental conditions will allow for a season of epic pollock reproduction that will begin to re-build the stock. If we continue with business as usual,though, it’s more likely that the fishery will collapse, with devastating consequences for the wildlife and people of Alaska.

The next year or two may be our last chance to save the fishing industry from itself. The key will be in taking action before things reach the point of no return, as appears to have happened with cod.  Most immediately, the pollock catch needs to be cut significantly, and the roe fishery should be suspended.

Many of the measures necessary to save the pollock fishery are just as needed in other fisheries around the country that are also reeling from overfishing. Across our oceans, fish have nowhere to find refuge and replenish their population – which is why we need to move quickly to establish a network of no-take marine reserves.

Until we move from simply managing fisheries in a vacuum to protecting the ecosystems that sustain them, fisheries managers will continue to be surprised by one economic and ecological disaster after another – and taxpayers could find themselves on the hook for yet another multi-billion dollar bailout.

Greenpeace calls on world leaders to stop rainforest destruction

Environmental groups are up in arms about training exercises conducted by the U.S. Navy -- not sonar this time, but underwater explosives. The Wild Fish Conservancy and Public Employees for Environmental Responsibility have filed a federal lawsuit against the Navy, saying its practice of training divers to explode dummy mines in Washington State's Puget Sound poses an unacceptable hazard to salmon, orcas, sea lions, birds, and other wildlife. The National Marine Fisheries Service conducted an environmental review of the practice, and the Navy has made some alterations to lessen its impact, but the groups say more could be done. Pointing to one training exercise that blew up at least 5,000 fish, the groups suggest that the training be conducted in the open ocean instead of shallow harbors and canals. "We are not trying to block Navy demolition exercises," says PEER's Adam Draper. "We are simply trying to induce the Navy to train without creating needless carnage."

‘Copenhagen Diagnosis’ offers a grim update to the IPCC’s climate science

The dams and aqueducts that shuttle water from California's Sacramento River Delta to the rest of the state will "appreciably increase jeopardy" to salmon and steelhead in the coming months, U.S. District Judge Oliver Wanger said Friday. But while Wanger agreed with environmentalists that "the three salmonid species are not viable and are all in jeopardy of extinction," he declined to order a short-term remedy. The National Marine Fisheries Service, in response to a successful lawsuit from the green groups, will by March come up with operational changes to California's water-export system that will hopefully be less harmful to fish. In the meantime, greens had asked that Wanger order an immediate cutback in agricultural water diversion, but he demurred. While waiting for March to roll around, green groups and water agencies will continue discussions on how to balance fish livelihood and irrigation needs.

‘Copenhagen Diagnosis’ offers a grim update to the IPCC’s climate science

Denying an injunction sought by the Humane Society, a federal judge has given the go-ahead to Oregon and Washington state officials to trap and kill salmon-gobbling sea lions near the Columbia River's Bonneville Dam. The animal-rights group sued after the National Marine Fisheries Service OK'd sea-lion culling last month. An official hearing on the Humane Society lawsuit could be held as early as mid-May, although sea-lion trapping, which could start next week, will likely be over by then.

‘Copenhagen Diagnosis’ offers a grim update to the IPCC’s climate science

Oregon and Washington state officials will have the authority to trap and, if necessary, kill up to 85 of the sea lions that gobble up threatened salmon at the Columbia River's Bonneville Dam, the National Marine Fisheries Service announced Tuesday. Sea lions, which enjoy a robust population but are nonetheless protected under the 1972 Marine Mammals Protection Act, have been visiting the dam to feast on salmon for years. State officials first must try to trap the animals and see whether an aquarium, zoo, or marine park will take them; if no facilities are available, or if the animals avoid entrapment, the sea lions can be killed. Critics of the plan say that not enough attention has been paid to the threats posed to salmon by fisherfolk, habitat loss, birds, water pollution, and dams.

‘Copenhagen Diagnosis’ offers a grim update to the IPCC’s climate science

To protect endangered Northwest salmon, the National Marine Fisheries Service suggests giving Oregon and Washington state officials the authority to kill sea lions, which last year gobbled up more than 4 percent of the salmon running through the Columbia River's Bonneville Dam. The action would likely result in about 30 sea lion deaths a year. The federal agency is taking public comment through Feb. 19 on its recommendation and three alternatives: taking no action, using nonlethal weapons to deter sea lions (which has so far been ineffective), and killing all of the 150 or so sea lions within five miles of the dam.

‘Copenhagen Diagnosis’ offers a grim update to the IPCC’s climate science

The third draft of a federal plan for protecting endangered salmon and steelhead in the Northwest's Columbia and Snake Rivers does not propose breaching the four hydroelectric dams that block the waterways, frustrating activists who have long lobbied for the dams' removal. The National Marine Fisheries Service says the plan for helping the salmon is significantly improved over the previous version, which was found to violate the Endangered Species Act, but environmental groups aren't so sure. "It's the same pig in a different tutu, but it still can't dance," says Todd True of green group Earthjustice. The salmon recovery plan will go through a comment process and require a judge's approval. Dilly-dallying isn't recommended: Northwest wild salmon populations are at 5 percent of historic levels.

Five environmental groups sue Navy over sonar use off Hawaii

Tensions over the U.S. Navy's use of sonar in anti-submarine exercises off Hawaii have resurfaced, and five green groups are suing to change the practice. Citing concerns that sonar can kill and injure whales, dolphins, and other marine mammals, the lawsuit names both the Navy and the National Marine Fisheries Service, which issues permits for the activities. It asks the court to stop the exercises -- 12 of which are planned through 2008 -- until an environmental impact study is completed and protective measures are enacted. The Navy maintains that it has gone "to great lengths" to be wicked careful, keeping an eye out for whales from on deck and from airplanes, and turning off sonar when the creatures get too close. But activists say some such practices have been abandoned, and claim the Navy is violating environmental laws. "The Navy is not above the law," says Marti Townsend of KAHEA, a Hawaiian environmental coalition. "Protecting the country includes following its laws, not skirting them."

Puget Sound orcas gain more protection; Florida manatees downlisted to threatened

Ninety endangered orcas in the Northwest may soon swim easier, as the National Marine Fisheries Service proposed Friday to designate nearly the entire Puget Sound -- about 2,500 square miles of water -- critical orca habitat. The usual suspects took the usual sides: developers opposed more regulation; enviros said the proposal didn't go far enough, since it excludes waters less than 20 feet deep, which is prime habitat for orca prey. The proposal will be open to public comment but could be final as soon as November. On the opposite side of the nation, Florida's wildlife commission voted last week to downlist the manatee from the state's endangered species list to threatened status, despite continued dangers from red tide, boats, and habitat loss; greens contend that the commission is being pressured by development and boating interests. The manatee is listed as endangered by the feds, but that status is also being reevaluated. Oh well, you know what they say: You orca some, you manatee some.

Exxon Valdez disaster still screwing up Prince William Sound

Wildlife in Alaska's Prince William Sound is still threatened by oil spilled from the tanker Exxon Valdez in 1989. According to a new study by researchers at the National Marine Fisheries Service, some 100 tons of oil still pollute the sound shoreline and are potentially accessible to foraging sea otters and ducks. Coincidentally, sea otter and duck populations have been slow to recover in the area. Exxon-funded studies have concluded that, in the words of an Exxon spokesflack, the sound "has recovered, it's healthy and it's thriving." Exxon has paid at least $900 million toward Valdez cleanup; under a 1991 settlement, Alaska and the feds can ask for up to $100 million more for sustained eco-damage. Exxon has refused to pay $4.5 billon in punitive damages related to the spill. In no way trying to counter the bad PR, Exxon released a report today claiming the company paid $3 billion in environment-related expenses last year, is trying to be more energy-efficient, and totally doesn't deserve its bad-guy rep.

Judge orders Bush admin to shift water to Klamath River salmon

Endangered Klamath River coho salmon -- what's left of them anyway -- scored a victory yesterday, as a federal judge ordered the Bureau of Reclamation to increase river flows in drought years and the National Marine Fisheries Service to develop a biological study that would lead to a more equitable split of water between fish and farmers. During low flows in the spring of 2002, thousands of juvenile salmon died in the Klamath, which runs from southern Oregon to northern California, and later that year about 70,000 adults migrating upriver to spawn died of a disease that California wildlife officials blame on low flows. Klamath coho are now on the brink of extinction, and chinook numbers in the river are so low that this year's commercial catch may be banned. Fish advocates hope the new ruling will end years of struggle over Klamath water. "We don't want to lurch from crisis to crisis," says Earthjustice lawyer Kristen Boyles. "We need to figure how to manage this scarce resource."

Feds say local recovery plan is enough to save Oregon's coastal coho

Oregon coastal coho salmon will not be returned to the federal threatened species list. The National Marine Fisheries Service says there's no need for federal protections, crediting improving fish numbers to the recovery plan developed by a coalition of local, state, and federal players, including the timber and agricultural industries. Coastal coho runs dropped to about 25,000 fish in 1997 -- from historic highs of about 1 million -- and currently hover around 100,000, according to Oregon wildlife officials. But salmon advocates, including some NMFS scientists, worry the stock's comeback may be due to recent weather patterns producing more food in the ocean, a variable that can change over time.

Bush admin takes unexpected step to save Washington state's orcas

Yesterday, the National Marine Fisheries Service surprised conservationists, cetacean lovers, and most other sentient beings, really, by declaring the orcas of Washington state's Puget Sound endangered. The move mandates a recovery plan and critical-habitat designations, and comes after years of debate over just how much chemical pollution, boat traffic, Navy sonar experimentation, and depletion of their favorite food (salmon) the sound's fluctuating population of resident orcas can withstand before dying out. Happily, Northwesterners with diverse stakes -- from orcaphiles to salmon fishers -- seem determined to save the iconic black and white cetaceans. "It's not like the spotted owl, where it's loggers versus owls," orca expert David Bain says. "We're all on the same side on this one."

Fisheries Service offers mild plan to preserve Puget Sound orcas

The much-beloved and much-beleaguered orcas of Puget Sound in Washington state are the focus of a tepid new National Marine Fisheries Service conservation plan. It emphasizes cleaning up the sound, preventing oil spills, and trying to boost the salmon population -- pretty much what the government is already doing, as even the NMFS admits. However, if the orcas are listed under the Endangered Species Act this December, as is being considered, a new, more intensive recovery plan will have to be devised. An estimated 91 of the black-and-white marine mammals now spend part of the year in the sound, up from a low of 79 four years ago; biologists say 120 would be the ideal number for a safely self-sustaining population. The orcas face a triple threat: chemical pollution of the water; boats and noise, which may be impeding their communication and hunting; and fewer and fewer salmon, the orcas' favorite food. "It's about the habitat; it's about prey availability; it's about the whole ecosystem," says marine activist Joe Gaydos.

Bush administration cuts protections for Pacific salmon habitat

In a move it says reaffirms its "commitment to salmon recovery," the Bush administration on Friday slashed critical habitat for Pacific salmon facing extinction. The National Marine Fisheries Service announced that federal protection for salmon habitat in California, Idaho, Oregon, and Washington would be cut from 167,700 miles of river to 33,300 miles -- encompassing only waterways that the 19 listed species of threatened and endangered salmon use today, rather than their historic range. The feds agreed to revise the scope of the habitat designation in response to a lawsuit filed by the home-construction industry and property-rights advocates, which claimed that the economic impacts of the earlier designation hadn't been assessed. Eco-advocates say this demonstrates the Bush administration's desire to gut the Endangered Species Act.

Emergency steps needed to save right whale from extinction, experts say

The North Atlantic right whale could face extinction within the next century, according to marine scientists writing in the journal Science. Only about 350 right whales are alive today, and the researchers estimate that their deaths may be underreported by up to 83 percent yearly. The scientists say at least eight right whales have died in the past 16 months, almost three times the average yearly rate observed over the past quarter-century. At least half of right-whale deaths are caused by humans, as the animals are struck by ships or entangled in fishing gear. The scientists are calling on the National Marine Fisheries Service to impose emergency restrictions on ship speeds and floating fishing lines. "We can't wait to deal with a bureaucratic maze," said Amy Knowlton of the New England Aquarium, one of the article's 18 coauthors. But NMFS is resistant to calls for emergency action, saying new rules to protect the whales are in the works.

New marine management rules may hamper restoration of fisheries

The National Marine Fisheries Service has released new guidelines for restoring depleted fish stocks, but some friends of the finned worry the rules may unduly favor the fishing industry. Current rules mandate that regional fisheries managers aim to restore stocks within 10 years. The newly proposed rules would let them devise variable timelines for fishery restoration based on how long it would take a stock to rebound if there were no fishing, plus the average time it takes the species to reach spawning age. This may lengthen the time managers have to restore some stocks, which fisheries expert Andrew Rosenberg terms "a biological risk." The new rules would also allow coordinated management of different species that live, swim, and get netted together, assuming that fish with similar life histories will respond to similar management plans. But this is shortsighted, says Rosenberg: "[A] species might be minor to a commercial fishery but still play a key role in an ecosystem; we are only worrying about the things we like to eat right now."

Historic bottom-fishing restrictions adopted for West Coast waters

The Pacific Fishery Management Council this week approved a permanent ban on trawl fishing for nearly 300,000 square miles of federal waters off the coasts of Washington, Oregon, and California. The plan -- which will now be forwarded to the National Marine Fisheries Service for final approval; it's expected to go into effect in early 2006 -- prohibits bottom trawling on seafloor area deeper than about 4,200 feet, and also includes dozens of shallower areas considered vital to the survival of groundfish like rockfish, lingcod, and Dover sole. Trawl fishers say that dragging nets willy-nilly across the seafloor has not contributed to the overall decline of West Coast groundfish stocks, but trawling critics think the ban will help protect sensitive habitats like coral beds and kelp forests, vital to fish and other species. However, since much of the area covered by the new plan is already too deep for trawling, it's hard to say whether the ban will contribute to fisheries recovery.

Feds propose threatened status for Puget Sound orcas

The National Marine Fisheries Service yesterday proposed giving threatened status to a population of 80-some orcas that spend their summers in Washington state's Puget Sound and the waters surrounding British Columbia's Vancouver Island. Government officials say the listing would be somewhat symbolic, as the marine mammals already receive some protections under state laws and federal laws in both the U.S. and Canada. But the announcement is still a victory for conservation groups that have been fighting a 2002 ruling by NMFS that the population wasn't distinct enough from other orca populations to merit protection under the Endangered Species Act. The agency now has up to a year to make a final decision and will take public comments for 90 days. Enviros hope the listing will go through and lead to closer scrutiny of shipping traffic, wastewater disposal, use of toxic chemicals, and other activities potentially harmful to orcas.

Bush Administration Won't Remove Northwest Dams to Save Salmon

The Bush administration announced yesterday that it will not remove dams from the Columbia and Snake rivers in the Northwest as part of its efforts to save endangered salmon runs. According to Bob Lohn of the National Marine Fisheries Service, "Our work shows that you can achieve recovery without removing the dams." The agency said that improvements in ocean conditions, combined with the installation of removable spillway weirs that can guide young fish through the dams, will push forward the recovery of endangered salmon, which NMFS claims is already underway. The policy marks a sharp break from four years ago, when federal agencies acknowledged that breaching the dams would be the most scientifically certain way to save the fish. John Kober of the National Wildlife Federation, which is leading a lawsuit over river operations in federal court, said that the agencies' reversal was a gift to President Bush's reelection campaign (Bush has promised not to breach the dams) that contradicts "decades of experience and volumes of their own scientific data."
