Oakdale Leader –
Earlier this month, CDFW released about 1 million fall run Chinook Salmon smolts into the Feather River at the Boyd’s Pump Launch facility. This experimental in-river release will provide fisheries biologists an important opportunity to study how fish respond under specific environmental conditions, as compared to fish released at other points in the river system.
Anglers have expressed concern that striped bass predation is high during this time period on the Feather River. While predation is always a threat to the young salmon, it is only one of the challenges they face throughout their complicated life cycle. The good news is that current high river flows favor increased downriver salmon survival.
“It’s critical that a portion of the population survives the treacherous journey downriver, eventually returning to pass their genes to their offspring,” said Jay Rowan, CDFW supervising fisheries biologist. “The traits those survivors pass on will help the species adapt to current conditions and better prepare them for long-term challenges such as climate change.”
Central Valley rivers like the Sacramento, Feather, American and Mokelumne have been modified through the addition of dams, river channelization and flow control.
