In the warmer waters of Southern Maryland and on the Eastern Shore, catfish, striped bass, and hybrid striped bass can do well. These species can survive waters exceeding 85 F during the summer months, and tolerate temperatures near freezing during the winter. Optimal growth for both species appears to be in the 74 to 78 F range. Striped bass and their hybrids currently require proper permits from the Maryland Department of Natural Resources. Advantages of Cage Culture Raising fish in cages is relatively simple, especially when compared with raising fish in open ponds.
Investment is relatively low if an existing body of water is available.
Harvest is generally simplified because the entire cage can be taken from the water and the fish removed. Otherwise, the fish are simply dipped out of the cage with a net. These harvest techniques eliminate the need for expensive harvesting equipment and labor. With cage culture, fish are easier to observe for general health and feeding behavior. Cages also facilitate treatment of diseased fish and reduce fish losses to bird and animal predation.
