Ultrasonic tracking proved to be a successful method for studying the behavior of largemouth bass in relation to water manipulation and other environmental parameters. Several preferred locations were selected by bass released in the spring and fall as opposed to one location by bass released in the summer and winter. Movement and activity were greater during the spring and fall and could explain the selection of more than one location for a home area. Three of the sonic tagged bass returned to the point of original capture after orientation. Remaining bass all passed their capture site at least once during their migration to other areas. Water temperature was the only parameter that could be associated with increased or decreased movement. Temperatures ranging from 50-75 degrees were associated with peak movement. Water manipulation affected the acreage of bass habitat available but resulted in neither increased nor decreased movement.
