I investigated the effect of electroshocking on the reproductive behavior of goldfish Carassius auratus and brook trout Salvelinus fontinalis. In the laboratory, 24 h after being stunned by 400-V pulsed DC, male and female goldfish spawned normally with sexually active conspecifics. Similarly, in an uncontrolled field study, nearly half of male and female brook trout collected by DC electroshocking on their spawning redds and subsequently released were later seen spawning. Although these results suggest that electroshocking does not have long-lasting effects on the behavior of two species of sexually mature fish, caution is still advised when using electroshocking to sample wild spawning fish.
