Electrofishing Catch Rates as an Index of Largemouth Bass Population Density in Two Large Reservoirs

&
 

Abstract

A shoreline electrofishing scheme with a stratified random design was developed for estimating largemouth bass Micropterus salmoides population density in Lake Norman, North Carolina, and Lake Wylie, North Carolina–South Carolina. Catch rates (number/100 m shoreline electrofished) of largemouth bass (≥200 mm total length) were linearly related (r = 0.98; P < 0.01) to population density estimates (number/hectare) obtained with mark-and-recapture methods.
