Walleye are among the most popular sport fishes in North America. However, they are a concern in areas where they are nonnative and have been introduced. Walleyes have been introduced to Lake Pend Oreille, Idaho, and are likley a threat to both species of recreational and conservation importance. We are closely with the Idaho Department of Fish and Game to better understand the potential influence of Walleyes on fishes in the system. Results of this work will provide a comprehensive understanding of the population dynamics of Walleyes and their food habits in Lake Pend Oreille. This information will be used to develop population models and bioenergetics models that, in turn, can be used to evaluate different management actions.
