Physiological Effects of Electrofishing on Largemouth Bass

Abstract
Blood and tissue samples of adult largemouth bass (Micropterus salmoides) were taken from control fish and from fish that were electroshocked and allowed recovery times of 0, 1, 3, 5.5, and 19 h. Shocking had no significant effect (P > 0.05) on hemoglobin, hematocrit, plasma protein, or percentage water content of tissue. No sexual differences in these factors were noted. Blood lactate increased significantly (P <0.01) l h after electroshocking, returned to pre-shocked levels within a 3-h period, and then continued to decline.
