Washington fishery managers are adding more details on their Christmas Eve press release about where they hope to get fall Chinook fry to replace nearly half of those lost during a power outage and backup generator failure.
The young fish would be transferred from a mix of state, tribal and college hatcheries located everywhere from the North Sound to Hood Canal to Deep South Sound.
They include WDFW’s Samish, Hoodsport and George Adams Hatcheries, the Nisqually Tribe’s Clear Creek Hatchery, the Suquamish Tribe’s Grovers Creek Hatchery and Bellingham Technical College’s Whatcom Creek Hatchery.
It wasn’t clear how many would come from each, but according to WDFW a total of 2.75 million replacement fish have been identified to partially make up for the loss of 5.7 million fall kings at Minter Creek following the December 14 windstorm.
The available “excess” fry, as they were called in the press release, are more of a “byproduct” during rearing than an insurance policy against catastrophic loss, according to WDFW spokesman Craig Bartlett.
“NOAA sets the parameters for smolt releases and hatchery managers want to make sure they raise enough fry to meet those targets. Since raising the exact number of fry needed isn’t possible, they’d rather raise a few too many than come up short,” he explained.
The National Oceanic and Atmospheric Administration’s Fisheries branch gave WDFW tentative approval to move the fish on the condition that the agency get nine treaty tribes to agree to it.
Bartlett said that as of earlier this week, four tribes had already and he hoped another five would after the holidays, when more state and tribal staffers are back in their offices.
A spokesman for NMFS’ West Coast region couldn’t be reached for comment on the caveat due to the partial government shutdown, but Eric Kinne, WDFW’s hatchery manager, typified it as “just part of co-management.”
The fry would be reared at Minter and released next spring in the creek there and at Tumwater Falls on the Deschutes River near Olympia.
WDFW Director Kelly Susewind called losing the fall fry along with half a million spring kings set for release in the White River “a painful setback for state and tribal fishers, for the communities that depend on fishing, and for southern resident orcas that feed on Chinook.”
A root cause analysis will be performed to figure out why the backup generator couldn’t be started for nearly three hours, cutting water flow to hundreds of trays holding thousands of Chinook each, depriving them of oxygen.
