A Comparison of a Fixed vs. Stratified Random Sampling Design for Electrofishing Largemouth Bass in Oklahoma
SEAFWA Journal Volume 1, March 2014
Two sampling designs were compared to evaluate Oklahoma's standardized sampling procedures for electrofishing largemouth bass (Micropterus salmoides) in reservoirs. Historical subjectively-chosen fixed sites were sampled along with random sites stratified by habitat category (good, fair, and poor) at four reservoirs in central Oklahoma. The stratified categories were determined by a composite of the shape/structure of the bottom, substrate type, and type of cover available in 0.5-km transects. Using the stratified random design, three of the four reservoirs showed significantly different (...
