Can Wisconsin Cash in on Yellow Perch Aquaculture?
Creating a yellow perch aquaculture industry is loaded with challenges. For one, the mature fish are smaller than many farmed fish. A dinner-sized portion may include five or six fillets on a plate, instead of a single tilapia or walleye fillet. That means raising more fish for each dinner.
Perch farmers have traditionally not controlled the diet of the fish during their early life stages. They often throw fingerlings into a pond and hope for the best. However, fertilizing the ponds to produce the right plankton for the perch to eat may pay off. Yet another challenge is that when they are moved indoors, the young fish need to be trained to change their diet from the zooplankton they ate in the pond to a completely new, freeze-dried diet.
Nevertheless, Wisconsin’s appetite for the firm, flaky fish is nearly insatiable. Overcoming the obstacles to raising yellow perch in aquaculture facilities could pay off tremendously. Check out the new video explaining how researchers funded by Sea Grant are tackling these challenges.
