Striped Bass Predation Continues to Contribute to Decline of Native Salmon

Predation by non-native species, including striped bass and black bass, is a leading cause of mortality among migrating juvenile salmon in the Delta.

Striped bass are a non-native species introduced for sport fishing. Federal fishery agencies consider the fish among the most important predators of juvenile salmon because of their vast numbers, and opportunistic and predatory feeding habits. The California Department of Fish and Game’s own experts have estimated that striped bass may consume upwards of 25-50 percent of endangered winter- and spring-run Chinook salmon.

Yet striped bass populations are misguidedly protected by size and bag limits to ensure these fish are available to recreational fishermen, at the cost of native, endangered salmon.

The Coalition continues to push regulatory agencies to address this known stressor on salmonids and other species in the Delta.
