Aquaculture

National Sea Grant Goal: Develop the scientific, technological information and expertise needed to propagate and successfully culture fish with commercial and/or recreational value to the United States as well as the rest of the world.

Wisconsin currently has a moderately sized yet diverse aquaculture industry that includes the production of food fish, baitfish and fish for stocking. This is a priority area for Wisconsin Sea Grant because the industry has great growth potential, particularly in the area of food fish production, due to the state’s ample supplies of high-quality water, land, labor and markets. The most likely candidates for expansion in Wisconsin are yellow perch and other cool-climate, freshwater fish species. One major obstacle to achieving the state’s aquaculture growth potential is conditioning these species to intensive culturing, including improving growth rates, reducing stress and disease, and controlling reproduction. Practical, cost-effective production parameters need to be developed, along with environmentally sound aquaculture systems focused on reducing water usage and waste effluents.
