From a recent PB mag CE article.
The natural spawning of yellow perch in our northern states occurs roughly in April through May at 53-57 F water temperatures and 12 hours of light (photoperiod). Yellow perch are an annual spring spawner with eggs being developed in the fish during the fall and winter cool period. The beginning of preparation for the spawn is triggered by a cold period that can extend for several months. One source provides the minimum cooling period is 160 days at 50 F and the optimum period is 185 days at 43 F. It appears that these light and temperature conditions during the fall/winter are critical for egg maturation and spawning.

…yellow perch juveniles were stocked at three densities (30, 60, and 90 per tank) in 160 gallon tanks in Alabama, in early January and maintained throughout the winter until mid-April. Fish were fed a commercial, slow-sinking pellet at 5% of body weight, and water temperature monitored. Survival was greater than 99%. When water temperature was below 68 F, growth was slow, in the 0.05 g/d range. When water temperature was above 68 F, growth was 10 times as high at roughly .50 g/d.
