In his e-mail to members of the fishery management council, Executive Director Donald McIsaac offered "an early alert to what at this point appears to be an unprecedented collapse in the abundance of adult California Central Valley ... fall Chinook salmon stocks."

The low number of juvenile salmon means this year's runs are likely to be even smaller.
Complete statistics on other key salmon runs won't be available for two weeks, but experts said it looks like a bad year for salmon elsewhere in the West.

It is difficult to point to a cause, but the fact that both hatchery and wild fish are showing low returns points to the ocean and estuaries, where salmon spend most of their lives, said Curt Melcher, deputy director of the Oregon Department of Fish and Wildlife.
Last year there were very unusual conditions in the ocean, Boyce said. Southwesterly winds blew all summer, driving warm waters near shore and disrupting the marine food chain.
Some fishers and environmentalists say they believe the sharp decline in Central Valley chinook is related to increased water exports from the Delta, which supplies drinking water to millions of people in drought-stricken Southern California, as well as irrigation for
"It's time to reduce pumping of Delta waters before we destroy the fish and wildlife species we appreciate so much in California," said Mike Sherwood, an attorney for Oakland-based Earthjustice.

Duncan MacLean, a Half Moon Bay fisher who is on a team that advises the fishery council, said he's bracing for hard times.
"It's probably going to be worse than anything we've experienced before," said MacLean, 58, who relies on salmon fishing for as much as 70 percent of his income. "It's going to put a lot of us out of business. I don't know how I am going to be paying my bills through the summer."
Dick Pool, who owns Concord-based fishing gear manufacturer Pro-Troll, said the salmon collapse will be felt in fishing communities all along the coast, noting that a recent study found that recreational anglers spend more than $2 billion annually in
"The impact is going to be huge," said Pool, a former board member of the American Sportfishing Association. "It will take its toll on manufacturing, retailers, wholesalers, fishermen and the charter fleet."

After three years of poor returns, the number of returning Klamath chinook in 2007 exceeded minimums set by federal fishery managers. Preliminary counts showed about 50,000 spawners, though low numbers of juvenile fish indicate there may be poor returns of adult salmon this year.

But in fall 2007, the number of spawners suddenly fell to just 90,414 fish, the second-lowest total since 1973. That includes wild and hatchery-raised fish.
The news came in a memo e-mailed Monday from the director of the Pacific Fishery Management Council to council board members.
The numbers are preliminary and normally are not made public until February. But they represent a steep drop from the 2006 return of about 270,000 chinook.
"It's frightening to think how far we've fallen so quickly," said J.D. Richey, a salmon fishing guide on the American River, a key tributary that contributes to the Valley's chinook run. "It's pretty bleak."
Even more worrisome, the count of 2-year-old chinook returning to spawn in 2007 was just 2,021 fish. That is not just a record low, but also a mere fraction of 36-year average of about 40,000 fish. Early spawners, also called "jacks," are considered a reliable indicator of the number of 3-year-old fish expected to spawn in the following year.
In addition, the 90,414 total falls below the council's minimum conservation target of 122,000 fish, which may compel officials to shorten the 2008 fishing season both in the ocean and in
"The magnitude of the low abundance … is such that the opening of all marine and freshwater fisheries impacting this important salmon stock will be questioned," Donald McIsaac, the council's executive director, wrote in the memo. He called the numbers "an early alert to what at this point appears to be an unprecedented collapse."
The Central Valley run includes fish that spawn on the
In 2006, the salmon season was drastically curtailed to protect the smaller
"It's going to be devastating," said Zeke Grader, executive director of the Pacific Coast Federation of Fishermen's Associations. "It could mean no fishing at all."
It remains unclear why the run fell off so sharply in 2007. But many indicators point to poor ocean health, which may, in turn, be caused by factors linked to global warming, according to researchers.
For several years, changes in wind patterns have halted or delayed deep upwelling currents in the ocean. The upwelling drives a food cycle that produces plankton, which in turn feed tiny shrimp-like krill. The krill, in turn, are the primary food for young salmon spending their first year in the ocean.
The upwelling disruptions may have contributed to a decline in krill along with their salmon predators. Krill also feed a variety of seabirds, many of which also have declined in number.
Other experts said they believe poor environmental conditions in the Sacramento-San Joaquin Delta are to blame. Six other fish species are declining there due to a combination of near-record water exports, poor water quality and competition for food from invasive species.
"It's just another piece of evidence that our management of the rivers and the estuary are insufficient to support these species," said Tina Swanson, senior scientist at the Bay Institute. "We need to do better, and really quickly."
Many anglers fear a reduced season in 2008, but it may not be much worse than what they just went through because of the poor chinook return.
Richey, for example, had only 10 percent of the usual number of clients booking salmon trips on the
"I basically just stopped offering salmon (trips) because there wasn't anything to catch," he said.
"To me, it just felt like there was a void in the Valley. It was odd. I guess having the chinook was something I've taken for granted all these years." #

Salmon arriving in record low numbers

The
The bad news for commercial and sport fishermen and the salmon-consuming public surfaced Tuesday when a fisheries-management group warned that the numbers of the bay's biggest wild salmon run had plummeted to near record lows.
In April, the Pacific Fishery Management Council will set restrictions on the salmon season, which typically starts in May. A shortage could drive up the price of West Coast wild salmon. The council's leaders said the news is troubling because normally healthy runs of
"The low returns are particularly distressing since this stock has consistently been the healthy 'workhorse' for salmon fisheries off California and most of Oregon," the council's executive director, Donald McIsaac, said in a statement Tuesday.
At its peak, the fall run has numbered hundreds of thousands of fish, exceeding 800,000 in some years. But this year the preliminary count has put the number at 90,000 adults returning to spawn in the

"We've known that the numbers were going to come in low, but we didn't know they would be this low," said Zeke Grader, executive director of the Pacific Coast Federation of Fishermen's Associations, which represents commercial fishermen.
"This could end up closing us," Grader said. "Part of what we're trying to do is put a fish on the table that people can afford."
A few more than 1,000 commercial fishermen who catch the Central Valley salmon in the ocean from
Grader, along with representatives of most sport and environmental groups, attribute the salmon decline primarily to
"Twenty years ago, we identified the amount of additional freshwater we needed for healthy fish," he said. A federal law was passed in 1988 to reserve water to help fish, but the water only makes it as far as the delta - not out to the bay, where it would help migrating fish like salmon, he said.
Pollution that drains off farms also hurts the fish, Grader said.
Heidi Rooks, an environmental program manager in the Department of Water Resources, said the salmon's woes probably are linked to the

"The main reason has been the collapse of the delta. The tiny little smolts aren't making it the 100 miles from the rivers to the bay. As the water exports have increased over the last five years, the food chain has been significantly affected," he said.
According to the American Sportfishing Association, there are 2.4 million recreational anglers in
The popular chinook salmon is the most recent of the fish that feed in the rivers, delta and the bay to suffer a loss in numbers, said Tina Swanson, senior scientist at the Bay Institute, an environmental group.
Delta smelt, threadfin shad, longfin smelt and striped bass have declined in numbers starting in the early 2000s, she said. "That's the same time that the salmon that returned this year to spawn were going through the delta," she said.
The five highest water-export years have all occurred since 2000, she said.
Today's adult fish were migrating out to the ocean in 2005, the year the delta exports hit a record high, Swanson said.
Salmon are hatched in the rivers and feed in the delta and bay. At three to four months, they move to the ocean, where they feed near shore before they head for the open ocean.
"Dams along the
The pumping system moves the juvenile salmon into large, open areas of the delta, where they are prey for bigger fish.
Scientists studying the decline in fish populations also consider the effect of the ocean environment, although they agree that it is still too early to measure the effects of global warming. They look at the timing of migrations and food availability, said William Sydeman, a biologist with the Farallon Institutes for Advanced Ecosystem Research.
He found that in 2005, 2006 and, to a lesser extent, in 2007, the breeding failures of the Cassin's auklet on the Farallones could be linked to the demise of krill in the marine environment at the time when the birds needed it.
Salmon, too, feed on krill, anchovies and other small aquatic creatures, which are affected in abundance by ocean conditions.
When salmon come through the bay to the ocean, they spend time in the Gulf of the Farallones, the same as the Cassin's auklets, where they need to find sufficient zooplankton and other food.
"The ocean environment has a strong influence on how many survive the initial period at sea and how many come back to spawn three to four years later in the Sacramento River," Sydeman said. #

Salmon collapse could force fishing restrictions; Regulators issue the warning as the number of chinook in the

SACRAMENTO -- -- Faced with an "unprecedented collapse" of California's Central Valley salmon population, federal regulators warned Tuesday that the West Coast fishing industry is on course toward steep restrictions this year.
The number of chinook salmon returning to the
Donald McIsaac, director of the Pacific Fishery Management Council, said the reason for the decline remains unclear.
But the numbers of chinook or king salmon returning to many other West Coast rivers were also down last year, and scientists suspect the culprit is ocean conditions linked to global warming.
"The implications of a precipitous decline could be substantial for both commercial and recreational fisheries coastwide," McIsaac said, drawing a comparison to 2006, when plummeting
Some environmentalists blamed the troubles on water exports from the Sacramento-San Joaquin River Delta, headwaters of the giant aqueducts that funnel water to
The Sacramento River's "missing salmon" were juveniles migrating to sea in spring 2005, when state and federal water managers "set records for pumping delta water south," said Mike Sherwood, an attorney with Earthjustice, a nonprofit environmental legal group that has been jousting with water managers over water exports.
McIsaac sent an e-mail late Monday to members of the Pacific Fishery Management Council outlining the steep salmon decline.
Only about 90,000 returning adult salmon were counted in the Central Valley in 2007, the second-lowest number on record and nearly one-tenth the all-time high of more than 800,000 five years ago.
McIsaac said he wanted to give council members "an early alert to what at this point appears to be an unprecedented collapse." Particularly worrisome, he said, is the historic slump in the number of returning 2-year-old salmon, which are used as an indicator of future adult salmon returns. Just 2,000 of the young fish returned to the
