Electrofishing mark-recapture and depletion methodologies evoke behavioral and physiological changes in cutthroat trout (Oncorhynchus clarki)

Mesa, Matthew G.

Abstract:

We examined the behavioral and physiological responses of wild and hatchery-reared cutthroat trout Oncorhynchus clarki subjected to a single electroshock, electroshock plus marking, and multiple electroshocking in natural and artificial streams.

This study focused on the differential effect of shiner competition on steelhead of different social standing. Survival of subordinate juvenile...
