Abstract	:	Consistent with previous archaeological studies, Sacramento perch (Archoplites interruptus) represented the greatest proportion of native fish remains among the nearly 49,000 elements identified in five large Central Valley freshwater samples (CA-SAC-15/H, CA-CCO-548, -647, -767, and CA-SJO-3) when individual species are considered. Further, we provide evidence that there is a bias in California’s zooarchaelogical record that may be due in part to differential decomposition rather than the fishing habits of native peoples. Distinctive skeletal features of the single sunfish species (Centrarchidae) in this assemblage also may account for the elevated numbers of Sacramento perch. Representatives of Centrarchidae and Cyprinidae were buried for over seven years and the remains then excavated and assessed for decomposition. We further discuss issues in which either locally abundant fishes are not represented as expected or the ethnographic record appears to be at odds with the California archaeological record.
