Amerikanischer Flussbarsch
Yellow perch is a viable species for aquaculture. This species has shown a net weight gain between 37 and 78 grams over a three-year period in a study that raised yellow perch in outdoor ponds. Yellow perch meet several characteristics that make a species fit for aquaculture. Some such characteristics are as follows: they are low on the food chain, needing an optimal protein content of 21-27%, are accepting of pelleted fish feed, grow well in high densities due to their schooling nature, and the fish do not turn cannibalistic at high densities. When grown in ponds or tanks, yellow perch do not exhibit off flavors compared to wild caught yellow perch. These fish become sexually mature before they reach market size under natural conditions. Yellow perch rely on environmental cues, such as cooler temperatures, to mature. Controlling the temperature of the system allows yellow perch to be grown to market size before they mature.
