Lake Austin, in central Texas, supported a popular trophy largemouth bass (Micropterus salmoides) fishery concomitant with conservative hydrilla (Hydrilla verticillata) management during the period 2002–2011. However, a change from this conservative approach to an aggressive stocking rate of triploid grass carp (Ctenopharyngodon idella) in response to excessive hydrilla growth between 2011–2013 subsequently resulted in the eradication of all submerged aquatic vegetation (SAV). The loss of SAV quickly changed the angling dynamics of the reservoir, resulting in a...

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...

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 (...
