Record Low for California Chinook Salmon

    Record Low for California Chinook Salmon

    Feb, 2008  - California Central Valley fall 
    Chinook salmon stocks appear to be undergoing a "significant decline," 
    said Pacific Fishery Management Council Director Donald McIsaac today. 
    Dr. McIsaac warned that if the low abundance is confirmed, all marine and 
    freshwater fisheries that target these salmon stocks could be affected. 
    "The low returns are particularly distressing since this stock has 
    consistently been the healthy work horse for salmon fisheries off 
    California and most of Oregon," he said. 
    The Pacific Council is a federal advisory panel responsible for managing 
    fisheries off the coasts of California, Oregon, and Washington. 
    
    Chinook salmon are also called king, spring, or tyee salmon, and are the 
    largest of the Pacific salmon. Chinook salmon are highly prized by 
    commercial, sport, and subsistence fishers. Like all Pacific salmon, 
    chinook are anadromous, which means they hatch in freshwater streams and 
    rivers, migrate to the ocean for feeding and growth, and return to their 
    natal waters to spawn. 
    California Central Valley fall run Chinook salmon spawn in the Sacramento 
    and San Joaquin River Basins and their tributaries. 
    California Central Valley fall Chinook salmon are not on the federal 
    endangered species list, but they were classified as a Species of Concern 
    on April 15, 2004. 
    Last week, the Council's Salmon Technical Team met to tabulate salmon 
    returns and catches. Two areas of bad news emerged. 
    First, in 2007 the adult spawning escapement for Sacramento River fall 
    Chinook salmon failed to meet the escapement goal of 122,000 to 180,000 
    adults for the first time in 15 years. 
    Sacramento River fall Chinook is the largest component of Central Valley 
    Chinook. 
    The escapement goal, or conservation objective, is the optimal number of 
    adult fish returning to spawn in order to maximize the production of the 
    stock. 
    Second, the count of "jacks" in the Central Valley fall Chinook return 
    this past fall was at a record low. Only 2,000 jacks returned, compared to 
    a long-term average of about 40,000 and the previous record low of 10,000. 
    
    Jacks are immature fish that return to the rivers at age two, unlike adult 
    fish, which return at age three or four. Their numbers are used to 
    forecast future returns. This suggests that 2008 abundance will probably 
    also be weak. 
    Last week, scientists questioned whether returns in 2008 could meet the 
    conservation objective even without any commercial or recreational salmon 
    fishing. 
    If returns do not meet the conservation objective, an emergency rule from 
    National Marine Fisheries Service may be required to allow any fisheries 
    at all, Dr. McIsaac said. 
    The reason for the decline is unclear, he said. Both hatchery and 
    naturally produced fish have been negatively affected, and returns of 
    coastal stocks in Oregon, in the Columbia River, and in British Columbia 
    were all low in 2007. 
    "The decline seems to be a coastwide phenomenon, probably related to ocean 
    conditions," he said. 
    The implications of a precipitous decline could be substantial for both 
    commercial and recreational fisheries coastwide. In 2006, a similar 
    decline in Klamath stocks led to major cutbacks in salmon fishing 
    opportunities. 
    Sacramento River salmon have a greater range than Klamath River stocks, 
    and are caught in California, Oregon, Washington, and British Columbia. 
    They are considered the "driver" of commercial fisheries in Oregon and 
    California, explained Dr. McIsaac. 
    The Council will consider these numbers and set harvest levels this 
    spring. In three to four weeks, the Council will release estimates of 
    salmon abundance for 2008. 
    Then, at its March 8-14 meeting in Sacramento, California, the Council 
    will develop a range of management options. Salmon management discussions 
    begin on Tuesday, March 11, when the Council will review 2007 salmon 
    fisheries, discuss stock abundance estimates, and tentatively adopt salmon 
    management measures for analysis by Council technical teams and 
    scientists. 
    Friday, the Council is scheduled to adopt management options for public 
    review. These options will probably range from status quo harvest levels 
    to significant closures. 
    Public hearings to receive input on the options are scheduled for March 31 
    in Westport, Washington and Coos Bay, Oregon, and for April 1 in Eureka, 
    California. The Council will consult with scientists, hear public comment, 
    and revise preliminary decisions until it chooses a final option at its 
    meeting during the week of April 7 in Seattle. 
    All Council meetings are open to the public. Based on previous experience 
    with Klamath fisheries, the Council expects there to be a large public 
    turnout at both the March and April meetings and the public hearings. 
    The Pacific Fishery Management Council is one of eight regional fishery 
    management councils established by the Magnuson Fishery Conservation and 
    Management Act of 1976 for the purpose of managing fisheries three to 200 
    miles offshore of the U.S. coastline.
