“It’s not the freshwater production of the juvenile chinook that is the reason this decline is occurring; it’s being driven by poor marine survival,” said Ed Jones, the lead for the initiative and sport fish coordinator for the Alaska Department of Fish and Game.
“We don’t know why but once these juvenile chinook salmon are entering the ocean they are not surviving at the rates they once did,” Jones added.“And at the same, we also are seeing younger and smaller chinook returning to spawn, and this obviously results in smaller fish being caught.”
May be worth watching this one. It brings to mind the Fraser River Sockeye study on overescapement, which counseled that results may vary depending on which ocean cycle was present.
