Title: Effects of an introduced piscivorous fish on native benthic fishes in a coastal river

Author: White, Jason L.; Harvey, Bret C.;

Date: 2001

Source: Freshwater Biology 46(7): 987-995.

Publication Series: Miscellaneous Publication

Description: We used field surveys to compare the density and mesohabitat-scale distribution of the native coastrange sculpin (Cottus aleuticus) and the prickly sculpin (C. asper) in coastal rivers in northwestern California, U.S.A., with and without an introduced piscivorous fish, the Sacramento pikeminnow, Ptychocheilus grandis. We also measured mortality of tethered prickly sculpin in a field experiment including river, habitat type (pools versus riffles) and cover as factors

Keywords: PSW4351, sculpin, cottidae, field experiment, introduced species, predation, Ptychocheilus grandi
