The yellow perch, Perca flavescens, is a sport fish native to much of North America east of the Rocky Mountains. Although the species is not native to Utah, it has been introduced to many Utah waters, and is now commonly found in the state.

Young yellow perch eat zooplankton, whereas adult yellow perch eat larger invertebrates, such as insects and snails, and small fishes. The species spawns in the spring, usually over areas with submerged vegetation; eggs hatch in ten to twenty days. Yellow perch populations grow quickly, and the fish will often stunt (remain small throughout life) due to over-crowding unless a significant number of perch are removed from the system through predation or angling.
