The demand for fish and seafood is increasing faster than natural fish stocks can reproduce leading to increased prices. Strong steady demand for fish has spurred the growth of intensive fish culture. In the Great Lakes area, yellow perch and sunfish are in high demand for weekly fish fries. Open pond culture has been the traditional cultural method in the Midwest but environmental regulations and restrictions on pond building is forcing the use of water recirculation system. These systems are compact and can be located near or within urban areas where markets exist. Recirculation systems have the advantage of being able to control the environment to optimize growth, eliminate predator issues, conserve water and reduce disease transmission from wild fish. The disadvantage of recirculation systems is that they are energy intensive because water is continuously being pumped to remove waste and supply oxygen.
