Black drum ( Pogonias cromis ) were cultured in 6.0 m 3 net cages made of knotless nylon coated with vinyl containing antifouling compounds and in 1.08 m 3 floating cylindrical wire cages made of plastic coated wire. The culture site was a cooling lake receiving from a power plant warm brackish effluent in which fouling organisms grow particularly well because of the high temperatures. Black drum grew slightly better in the net cages than in the wire cages. The coating on the net cages prevented fouling without inhibiting growth of the fish. Net cages are recommended for the culture of fish because they are cheaper, foul less, require less labor and better withstand bad weather compared to wire cages.
