A large number of around 830,000 salmon fry released into Northern California’s Klamath River are believed to have died after they suffered gas bubble disease, state wildlife officials said Monday.
The condition is caused by a severe change in pressure. It happened as the fish went through the Iron Gate Dam tunnel, the California Fish and Wildlife Department said.
The tunnel and the dam of the same name will be removed later this year.
The around 830,000 Chinook salmon fry were the first release from the Fall Creek Fish Hatchery, which was a $35 million project designed to support salmon populations in the Klamath River once it is fully undammed, the wildlife department, known as the CDFW, said in a statement.
