Population estimate, exploitation, mortality, movement, and habitat use of Lake Sharpe Walleye as inferred from mark-recapture and acoustic-telemetry tracking

The Lake Sharpe Walleye population provides the third largest fishery resource to South Dakota anglers and routinely contributes between $3.3 to $8.5 million in direct economic input annually. Because of the high recreational and economic importance to the state, the Lake Sharpe Walleye population is being evaluated to determine best management procedures (BMPs). A crucial step in determining the BMPs is understanding population dynamics that biologists can use to model the effects of various management regulations on the population. A wealth of information has been gained by the current tagging study on Lake Oahe and information gained from this study has laid a foundation for future regulation modeling and management of this lake. This study will provide additional information regarding differential exploitation, spatially and temporally varying movement patterns and habitat use, all of which are essential for regulation modeling of the Walleye fishery in Lake Sharpe.
