Abstract: The preservation and monitoring of age-0 fishes and their habitat is imperative to the overall health of a lake and its fishery. The effectiveness of backpack electrofishing at capturing age-0 fishes along shorelines with coarse woody structure was assessed by attempting to correlate electrofishing catch rates with known population sizes. A 60x2m controlled study area along the shoreline of Lower St. Regis lake was selected and blocked off through use of a net encompassing the perimeter. Known population sizes were stocked into the net and a three-pass electrofishing depletion was conducted within the study area. Results indicated that there was no significant correlation between the known population size and the population estimate generated through electrofishing (p = 0.172). The lack of correlation may have been due to failure of the block net encompassing the study area.
