Impact of smallmouth bass predation on subyearling fall Chinook salmon over a broad river continuum.

Smallmouth bass () predation on subyearling fall Chinook salmon () was examined in the Snake River (USA) to identify seasonal and habitat-related changes in bass diets, and associated subyearling consumption and loss in various riverine and impounded reaches. Smallmouth bass diets reflected opportunistic foraging that at times showed predation on subyearlings is influenced by the consumption of other prey such as crayfish, sand roller (), and smaller invertebrates. Estimated loss of subyearlings was influenced by bass abundance and consumption rates.
