A new study by researchers at the Wild Fish Conservancy and Raincoast Conservation Foundation has found that marine salmon fisheries along the Pacific coast typically harvest Chinook too early in their life cycle, before they reach their full size as adults. The implications from this are far reaching for fisheries, future Chinook runs, and the ecosystem.
The study, published this week in the journal Scientific Reports, examined the effects of “mixed- maturation fisheries,” where both immature and mature Chinook salmon are harvested together in coastal marine waters. This modern fishing practice may be contributing to widespread declines in the age and size of Chinook salmon across the northeast Pacific.
“These fisheries are generally catching salmon before they have the chance to fully grow,” said co-author Misty MacDuffee of Raincoast Conservation Foundation. “Over time, this can lead to younger, smaller Chinook salmon with ripple effects for fisheries, wildlife and future salmon runs.”
