Differences in Angler Catch and Exploitation of Walleye from Virginia Waters

SEAFWA Journal Volume 1, March 2014

Walleye (Sander vitreus) were collected during late winter-early spring in 2008 - 2011 at seven sites across Virginia to evaluate angler catch and exploitation. A total of 3116 walleye were tagged with FD94 T-bar Floy tags at four small impoundments (<200 ha), two large impoundments (>200 ha), and the New River during the course of the study. Anglers were offered a US$20 reward for the return of each tag, and 530 tags (17%) were returned. Adjusted annual catch rates ranged from 15% - 61%, with a mean of 29%. Annual exploitation ranged from 2% - 29% with a mean of 12%. Mean total...

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 (...
