The effects of different densities of vegetation on the foraging behavior of largemouth bass, Micropterus salmoides, were examined in the laboratory. Prey encounter rates and handling times and the swimming velocities of the bass while searching for and handling prey were significantly influenced by changes in the amount of vegetation. An optimal-foraging model was then used to predict prey selection by the bass in two environments with identical prey communities but different densities of macrophytes. Consumption of prey by the bass corresponded closely with the predictions of the model. (Copyright (c) 1984 by the Ecological Society of America.)
