Yellow perch (Perca flavescens) are in great demand in the upper midwest around the Great Lakes area. The supply of this species from natural waters is declining rapidly while the demand is increasing. To supplement the natural supply a system of culture for this species under controlled environmental conditions has been developed at the University of Wisconsin‐Madison. The fish are raised from fingerling to market size (150 g) in 9 to 11 months on a pelleted feed at water temperatures of 21 C and photoperiods of 16 hr. The water used in the system is cycled through biological filters so that it can be used approximately 20 times. Feed conversion is approximately 1.5. The fish have an excellent flavor and yield approximately 5% more fillets than fish from natural waters.
