Sander vitreus

Understanding walleye (Sander vitreus) spawning behavior is important for managing walleye fisheries, but such information is limited for Appalachian reservoirs. We assessed spawning movements and spawning locations for a reestablished walleye population in Cheat Lake, West Virginia. We tagged fifty-two walleye with acoustic telemetry transmitters to evaluate environmental correlates associated with pre-spawn movements and to deter- mine spawning locations. Using an information-theoretic approach, we compared candidate logistic regression models to determine...

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...
