California drought puts Chinook salmon in danger of extinction

Another deadly summer of drought has heightened fears of extinction in the wild for an iconic California salmon, federal officials said Wednesday.
Officials with the National Marine Fisheries Service said preliminary counts indicate that hot, shallow waters caused by the drought killed most of this year’s juvenile winter-run Chinook before they made it out to the Pacific Ocean.
It “doesn’t look very good,” said Garwin Yip, a federal fisheries spokesman.If a final count this winter confirms the bad news, it would mean a second straight summer in which 5 percent or less of the young fish survived California’s drought.
Since the fish spawn on a three-year cycle, the die-off would make management of next year’s water critical for the salmon’s survival in the wild.
The development suggests failure for a second year in a row for federal efforts to manage water flows from Lake Shasta, a main reservoir in the state’s water system, to keep salmon and other species alive.
“Droughts are always hard on salmon, but water management decisions made it worse this year,” said John McManus, executive director of the Golden Gate Salmon Association.
The juvenile salmon depend on water temperatures in the mid-50s, and were unable to survive in the warmer temperatures produced by shallower than usual water.
Chinook salmon are a mainstay of the state’s commercial fishing industry. California’s fishing industry and environmental groups are vying with the state’s farmers for diminishing water supplies in the driest four years on record.

More days for commercial salmon fishing, but drought cycle looms

The North Coast fishing fleet got its first glimpse this week of rules guiding the commercial salmon season set to start May 1, including more days on the water this year than last, reflecting a hopeful outlook for the catch this year despite grim a cycle set in motion by the statewide drought.
The schedule set for the Fort Bragg region, in particular, is far more generous this year, with the season opening a month earlier than in 2014 and dates that allow seven additional days of fishing split between June and July.
Only one fishing day has been added for the coastal waters that include the Sonoma Coast and Bodega Bay, home port to 40 or 50 fishing vessels.
“This year we kind of bet that there’s going to be a northern shift (in the salmon stocks) because of ocean conditions,” said McKinleyville fisherman Dave Bitts, a member of the salmon advisory subcommittee to the Pacific Fishery Management Council, which oversees coastal fisheries off California, Oregon and Washington.
The season outlines were predicted by a relatively optimistic forecast released in February for the Sacramento River fall run of chinook salmon, which largely determines the North Coast harvest. Analysts predict about 652,000 adult chinook are waiting off the coast this year, about 18 percent more than are believed to have been in the ocean a year ago.
Any satisfaction with the current forecast, however, is somewhat overshadowed by concerns about the future, when adult salmon populations will more fully reveal the impact of three years of drought on spawning and offspring survival.
“This might be the last full season for four years,” longtime Bodega Bay fisherman Chris Lawson said. “We never do see what we call a traditional full season anymore, but this might be the most allotted time for we don’t know when. I can’t even say four years. I won’t know until it starts raining and fish populations come back.”
