The ocean salmon fishing season is set to open on April 2 and fishery managers estimate that coastal waters currently boast more salmon than at any time in the past five years. Indeed, it appears that the severe drop in the Chinook salmon population in recent seasons has reversed. But the question is why? Is it more rain and snow in the Sierra, resulting in more freshwater in the Sacramento-San Joaquin River Delta? Or, is it more food for salmon in the Pacific Ocean?
Actually, some scientific data indicate that the salmon resurgence is artificial and has nothing to do with the health of the delta or the ocean. In fact, data from a program that tags young salmon and recaptures them suggest that an elaborate system that trucks salmon from Central Valley fish hatcheries and deposits them into San Pablo Bay is primarily responsible for the salmon recovery. Some experts believe that without this artificial life-support system, the salmon in the Sacramento River might all but vanish. That's because the trucking system enables fish to bypass the delta and avoid the deadly pumps that send water to the San Joaquin Valley and Southern California.Biologists with the California Department of Fish and Game and the US Fish and Wildlife Service found that tagged salmon, or smolts, born in hatcheries, loaded into tanks, and transported to release sites near the Carquinez Strait are several times more likely to appear as adults in catch surveys than those that are left to travel unassisted downstream, through the delta, and out to sea. Experts suspect that non-trucked salmon are dying in the delta, where pumping facilities create hazards for small fish, either killing them directly or drawing them into sloughs and backwaters, where predators await.
Information collected by the National Marine Fisheries Service has shown that as many as 92 percent of young, non-trucked salmon die in the delta. "Getting the fish around the delta is critical," explained Roger Thomas, captain of the Salty Lady, a party fishing boat in Sausalito, and a board member of the Golden Gate Salmon Association. "Until we improve the health of the (river's) ecosystem, we'll have to keep trucking the fish."
The revelations about salmon survival rates come from a joint effort by state and federal fishery managers to tag a portion of the 30 million fish they produce annually in Central Valley hatcheries and observe their rates of survival into adulthood. To make the young fish identifiable as adults, hatchery managers clip the salmon's fleshy dorsal lobe, called the adipose fin, from 25 percent of smolts prior to release. The same fish are fitted with nearly-microscopic "coded wire tags" imprinted with numeric data. Last year, 121 of these fin-clipped salmon — caught as adults — were reported by sport fishermen on boats out of Sausalito. Fish and Game biologists who removed and analyzed the coded wire tags from the 121 fish found that 81 — or 66 percent — had been trucked around the delta and released into San Pablo Bay.
In addition, coded wire tags turned over by commercial ocean fishermen that same summer showed that fish born in 2008 at the Coleman National Fish Hatchery on the Sacramento River and trucked to San Pablo Bay were seven times more likely to reach adulthood than fish from the same hatchery that were released into the river. Wild salmon must also navigate their way to the sea unassisted and presumably face the same threats as the non-trucked hatchery fish in the delta region.
Fishery data also suggest that the recent collapse of the salmon fishery may have been due in part to a suspension of the salmon-trucking system in 2005 and 2006, an interruption caused by state budget constraints. Adult salmon populations crashed in the following years. The program has resumed in force, and salmon numbers appear to be climbing. Biologists estimate that 1.1 million adult fish are currently off the California coast — about three times the estimated ocean population of last spring.
However, some experts blame other factors for the salmon collapse and recovery. Two panels of government biologists appointed by the Pacific Fishery Management Council, or P-Council, proposed in a recent report that the salmon collapse over the past few years was due to food shortages in the Pacific Ocean in 2005 and 2006 caused by a lack of upwelling of nutrient-packed waters from the ocean floor.
Still, other experts, including a coauthor of the report, Chuck Tracy, a P-Council salmon staff officer, believes excessive water diversions from the delta played a major role in the collapse of the fall-run salmon population. The run hit rock bottom in the fall of 2009, when 39,000 spawning adults returned to the Sacramento River — down from 800,000 in 2002. In an interview, Tracy said high delta pumping levels in the spring of 2007 combined with half or less the rainfall of normal years to create "a ratio of pumping to water in the river that was much higher than usual."
The conflicting data and opinions have left some fishery experts unsure as to the impact of the trucking program. For example, Melodie Palmer-Zwahlen, a biologist with Fish and Game's Ocean Salmon Project who is currently analyzing data from the coded wire tags collected last summer by Bay Area ocean sport fishermen, remains undecided as to what is driving the rise and fall of salmon numbers. "Is something happening to these salmon in the river," she asked, "or is something happening at sea?"
But Dick Pool, president of the Concord-based fish conservation group Water4Fish, feels certain that the key problems dwell in the delta. "The ocean conditions did zap a lot of the fish in 2005 and 2006, but since then we've had excellent ocean conditions, but the fall run collapsed into a disaster zone," said Pool. He believes the delta environment remains as devastated as ever and that the salmon population could easily crash again. "Without that trucking program," he said, "we might have no ocean fishery."

Editor's Note:
For far too long no one was paying attention to the health of the Delta and what an important component a healthy Delta is to our fisheries. Over the past few years the Delta, with it's flows pumped to Kern county and the remaining water polluted by agriculture runoff and waste water discharges has been slowly dying.
For the past three decades we have watched sport and commercial fisheries decline due to increased water diversion and the polluting of the largest estuary on the west coast. Nearly all of our sport fisheries are connected, one way or another to the Delta. Salmon, striped bass, sturgeon and steelhead are all at record low numbers .
The tide however is starting to turn. There have been a handful of favorable court rulings and studies released from federal agencies that show that decreasing water diversion is key to restoring the Delta. Five years ago there were a handful of groups working to protect the Delta. Today there are dozens all fighting to bring it back. These groups need to support of sports-men and women like YOU. Unfortunately the majority of so called "sportsmen" have not supported these groups. If these fisheries are ever going to rebound then sportsmen MUST get involved.
Below we have a series of stories to educate readers. Find out how SalmonAid (started by a good friend of mine Mike Hudson) is holding Salmon Month at Pier 39 all this month. Read about how much of the water is controlled by private billionaire interests in Kern County who are not diverting water just for crops but are actual reselling it to a 500% profit. Or how Western Bass is holding auctions and fishing tournaments to support others like Restorethedelta.
This groundswell of support is starting to turn the tide on decline of the Delta and we urge readers to ride the wave and support these groups NOW!
SALMONAID ENDEAVORS TO HELP FISHERMEN
SalmonAid presents Salmon Month at the Aquarium of the Bay in San Francisco. Salmon fishermen, a group of independent family-owned enterprises, need help to restore the collapsing California salmon fisheries. Through September, a variety of activities will be held at San Francisco's Aquarium of the Bay, including a "Meet the Fishermen" colloquium sponsored by the Institute for Fisheries Resources, a film festival, a kids' activities weekend and a music festival. For more information, go to www.salmonaid.org. These are family-oriented events that will be great fun as well as highly educational.
“If we are unapologetic advocates for our wild salmon, we also understand and respect the legitimate interests of the farming community,” said Zeke Grader, Executive Director of the Pacific Coast Federation of Fishermen’s Associations (PCFFA). But salmon protection adversaries include western San Joaquin Valley’s gigantic corporate farms, “agribusinesses which have commandeered the State’s water supplies for their own parochial -- if very profitable -- interests. These corporations receive vast quantities of government subsidized water at absurdly low prices. Increasingly, they do not even use the water to grow crops -- they sell it for exorbitant profits to south state municipalities and developers,” Grader comments in a recent SF Chronicle Blog posting.

So please participate in the upcoming SalmonAid events at the Aquarium of the Bay if you can. And do what you can to support our west coast salmon fishermen and real family farmers. They sustainably provide us with delicious, wholesome food. We need them as much as they need us. Read more at: http://www.sfgate.com/cgi-bin/blogs/zgrader/detail?entry_id=71316#ixzz0yOerij12

SALMON WATER NOW RELEASES “BULLIES OF WESTLANDS” VIDEO
Bruce Tokars of the organization Salmon Water Now disputes the recent Westlands Water District’s claims that reduced water deliveries have put America’s agricultural output in jeopardy. "We contrast the Westlands record, including surplus crops of tomatoes and almonds shipped to China, against the low numbers of salmon that are sold domestically for $20 a pound," noted Tokars. His new informational video, “Bullies of Westlands,” can be found at:

IN CALIFORNIA, IT’S WATER FOR PROFIT AT TAXPAYER EXPENSE
“As a result statewide agriculture exceeds 36.2 billion dollars and exports account for 10.3 billion and growing. For example, almond production is so high that bulk prices are less than half of what they were a decade ago. Growers are looking for new ways to promote their product while 80% of the product gets exported. In fact, 50% of the top seven farm products in California are exported to China, Asia, Canada and Europe. Water for food? Hardly; water for profit is more like it.
“Serious problems began in 1995 when The Water Resources Agency privatized the Kern Water bank under the Monterey plus Amendments. The State essentially handed over one million acre feet of water to private investors. The Kern water bank is now owned by Westlands water district which is comprised largely of corporate farms. These corporate farms were essentially junior water rights holders. Historically Westlands received surplus water and grew annual crops. With this new water deal Westlands now has the capacity to grow vineyards and fruit trees.
“Today commercial fishing boats are gone from coastal harbors. Four species of salmon are threatened. Sport fishing related revenue losses equal 2 billion dollars and fishing license sales are off by 50%. That’s one million licenses which is another thirty six million dollars of losses to the state. “The answer is simple; if the state would charge for its water instead of giving it away the state could earn revenue while slowing agricultural growth and urban development. Balanced water usage would restore threatened fisheries while agricultural commodities increase. Commercial fisheries would recover consecutively. The facts are clear -- agriculture has profited in this decade and there are dead fish in this water policy…”

Salmon
anglers are looking forward to what promises to be a
good
salmon season in 2012. The Pacific Fishery Management Council (PFMC) released
spawning escapement numbers
for the 2011 Central Valley
(CV) rivers this past week.
Adult returns to all CV
rivers were just 122,000
adults (all numbers are
rounded) and a huge run of
jacks numbering 70,000.
Looking back the projected
CV escapement was 377,000 so
the actual return was just
31% of the preseason
estimate.
