Predators Decimate Young Salmon
Water managers have been saying for years that California’s salmon population is under attack by non-native predatory fish. Now there is science to prove it.

Striped bass and largemouth bass, as well as channel catfish and white catfish, were identified as the predators doing the most damage to young salmon. It is estimated the current bass population needs about 27,500 tons of food in a year to sustain itself. Of that, about 264 tons is salmon.

That means this predator has the capability of decimating the entire salmon population in any given year.

Bass were introduced to the Delta from the East Coast 130 years ago to populate a new western commercial fishery. These non-native fish, as well as critical habitat loss, Asian clams that compete for food, and water hyacinth all contribute to poor conditions for native fish like salmon.
