The logperch, Pecina caprodes, is a darter that is not native to Utah, but has become established in Willard Bay Reservoir in Box Elder County. Logperch are native to the eastern United States, and to the northern part of the central United States, including the Great Lakes region. Although not an excellent forage fish, the logperch serves as food for the larger fishes which inhabit Willard Bay Reservoir.
Logperch form schools and eat primarily invertebrates, especially insects. The species spawns in the spring over sand and gravel in shallow water.
