300 Spawners Released In Resoration Bid

SALMON
CREEK - Up until a few days ago the last time anybody spotted salmon in
Salmon Creek was back in the mid 1990’s, when the fish finally
succumbed to habitat destruction and drought.
This being an era
of promised change, however, the dozen or so biologists, volunteers and
the local land owner were on hand to witness the release of 300 mature
coho salmon into the creek where it runs through Chanslor Ranch north
of Bodega Bay.
The hope is the release of the spawning size fish
will change Salmon Creek from a salmon-less stream into one that has
some, particularly since California coho, or silver salmon, continue to
maintain a thin margin of survival despite efforts to save them.
California
Fish and Game supervising senior biologist Bob Coey and DFG colleague
Gail Seymour, say the extensive community interest in and restoration
of the creeks watershed over the past several years is making the
possibility of re-establishing a salmon run in Salmon Creek,
particularly a coho salmon run, a reality.
“We’ve got pretty
good habitat in Fay Creek,” said Seymour of an important upstream
tributary. “There’s been a lot of assessment and restoration work that
has occurred through collaboration with landowners and the agencies.”
That
work, according to Lisa Hulette, executive director of the Gold Ridge
Resource Conservation District, has included community volunteers,
willing landowners as well as support from local, state and federal
agencies, including California Fish and Game, the State Coastal
Conservancy, the California Water Resources Control Board, the
Community Foundation, the Occidental Arts and Ecology Center and the
Occidental-based Prunuske Chatham Inc., restoration firm, among others.
According to California Trout Unlimited, coho salmon were once found in
coastal Pacific streams from Monterey Bay to Alaska. According to TU,
California had an estimated 500,000 coho salmon in the 1940’s a number
now down to about 5,000 fish.
“Coho were last seen in here, to
all accounts, back in 1996 and there weren’t many then,” said Coey, who
co-founded and who supervises an on-going Department Fish and Game coho
salmon recovery-breeding program. “I think the last big drought did
them in.”
He said the released fish are surplus fish from the
recovery-breeding program and are from both the Russian River and from
the Lagunitas Creek watersheds.
California’s coho situation,
meanwhile, mirrors challenges faced by many state salmonid populations,
including chinook salmon, a major salmon species that has undergone
severe population reduction in California waters and is listed as
threatened in the Russian River watershed.
Coho, one of seven
species of Pacific salmon belonging to the genus Oncorhynchus,
according to TU, and one of five species found in California, is listed
as endangered.
Coho normally spend their initial year in fresh
water and the next two in salt water before returning to spawn in their
birth streams once winter rains have opened up many of the sand bars
that close small coastal during the summer.
Meanwhile, back at
the creek, Coey, said the fish, mature spawners weighing between 1.5 to
2 pounds, will hopefully not only survive to repopulate the stream but
provide a genetic link to the fish that historically spawned in Salmon
Creek even though they were not hatched there.
Both Coey and
Seymour say the hope is that the Russian River fish, which appear to
grow larger than their southern, Marin County, counterparts, will none
the less mix genes enough to come close to matching the original
genetics found in the creek’s extirpated coho population.
They
said the hope of success, in addition to the restoration work, is being
bolstered by recent ocean conditions, including resumption of food
producing upwellings that have been missing in the past couple years,
that should help smolts survive their ocean journey home.
“The situation is unique,” Coey said.
