Physiological Response of Some Economically Important Freshwater Salmonids to Catch‐and‐Release Fishing
Abstract Catch‐and‐release fishing regulations are widely used by fishery resource managers to maintain both the quantity and quality of sport fish populations. We evaluated blood chemistry disturbances in wild brook trout Salvelinus fontinalis, brown trout Salmo trutta, cutthroat trout Oncorhynchus...
