Hatchery works to ID fish before release
Clipping fins on fish fry keeps Rowdy Creek Fish Hatchery busy this time of year.
The hatchery is looking for volunteers to help mark 100,000 chinook salmon to be released later this year. Call hatchery manager Andy Van Scoyk at 707-487-3443 to get involved.
"It's a good way to give back to the community especially as a fisherman or a guide," said Steve McCown, a hatchery fish technician.
Although sometimes tedious, it's an interesting process. First the
lively fry are anesthetized with carbon dioxide so they swim slower and
are easier to handle.
Then, salmon fry no longer than a human finger have their adipose fin
(the top fin in front of the tail fin) clipped so they can be
"I'm making adipose soup," McCown joked about a tub filled with
After the clip, a coded wire, 1.1 mm long, is inserted in the fish's
snout so the California Department of Fish and Game can figure out where
the fish came from. A tag injector machine uses magnetic force to shoot
the wire into the salmon fry.
After these two steps, the fish is thrown into a device that checks
for quality control. If it senses a coded wire, it squirts a gush of
water to send the fry down a small pipe leading to a pool where the fry
wait to be released. If no wire tag is detected, the fish goes to the
rejection bucket to be tagged again.
With more restrictive fishing regulations, Rowdy Creek produces some
of the only Smith River fish you can take home for dinner.
During this past year's winter fishing season, anglers could not keep
a single wild steelhead trout, and only five wild chinook salmon could
be kept all year. Hatchery salmon (one per day) and steelhead (two per
day) can be kept all year.
About 51,000 steelhead will be released from the hatchery this year.
Steelheads don't require the wire tag since they are not caught in the
Rowdy Creek is the only privately funded hatchery in the state. Most
hatcheries in California are funded by "mitigators" or dam owners that
built dams on the rivers in the first place, said Mark Clifford,
statewide hatchery coordinator. For example, the Bureau of Reclamation
built the dam on the Trinity River and also funds the Trinity River
Without any dams on the Smith, the Rowdy Creek hatchery funds itself.
That being said, funds are tight at the hatchery and volunteers
aren't the only type of help needed.
"Our funding is down probably 40 percent," said Steven Westbrook,
president of the hatchery's board. "We rely on the generosity of people
making contributions and people have less disposable income right now."
The hatchery's budget has also increased from higher energy bills and
new regulatory requirements like the coded wire tags, Westbrook said.
This is the first year the hatchery had to cover part of the costs for
the tags required by DFG. The hatchery's share was $2,500.
"We can use volunteers, goods or services," Westbrook said. "Nothing
is too small."
The hatchery's primary fundraiser is the two fishing derbies (Chopper
Derby and Hank "Raider" Derby) it holds in early spring.
In the past, some funding came from DFG's Fisheries Restoration Grant
program, but projects to recover endangered species-listed fish like
coho salmon get first priority.
The "threatened species" listing of coho has also caused hatcheries
statewide to be scrutinized closer, because of how they could impact
wild fish, including coho.
"If (wild and hatchery fish) coincide in an estuary at the same time,
there's going to be competition," Van Scoyk said.
The hatchery has been in operation for more than 40 years.
Volunteers must be at least 16 years old.
