Chinook Salmon Fisheries Collapsing

WILD FACTS SERIES

Chinook salmon stocks are collapsing. West Coast fisheries managers recommended all commercial and sport salmon fishing in coastal waters off California and most of Oregon be halted to preserve collapsing Chinook salmon stocks.

“This is a disaster for West Coast salmon fisheries,” said Don Hansen, chairman of the Pacific Fishery Management Council.

Between 2000 and 2005, the annual catch for Chinook salmon in California and Oregon fisheries was about 800,000, according to the council.

In 2002, 775,000 Chinook salmon returned to the Sacramento River to spawn; however, the managers project only 54,000 Chinook will return this year even with the fishing restrictions imposed. Report

Chinook salmon may spend between one to eight years in the ocean before returning to their home rivers to spawn, though the average is three to four years. Chinook prefer larger and deeper water to spawn in than other species of salmon and can be found on the spawning redds (nests) from September through to December. After laying eggs in a redd, adult female Chinook will guard the redd from 4 to 25 days before dying, while males look for additional mates. Chinook salmon eggs will hatch, depending upon water temperatures, 90 to 150 days after deposition. Eggs are deposited at a time to ensure that young salmon fry emerge during appropriate time for juvenile survival and growth.

Chinook salmon range from San Francisco Bay in California to north of the Bering Strait in Alaska, and the arctic waters of Canada and Russia (the Chukchi Sea ), including the entire Pacific coast in between. Populations occur in Asia as far south as the islands of Japan. In Russia, they are found in Kamchatka and the Kuril Islands.

PORTLAND, Oregon (Reuters) – The U.S. government on Thursday closed almost all of the ocean off the West Coast to salmon fishing, clearing the way for governors of states hard hit by years of declining catches to seek federal relief aid for losses estimated at $290 million. (Source)
