Comparative experiments in brackish water and freshwater pond culture of rainbow trout (Salmo gairdneri) were conducted from November 1974 to March 1975 at Claude Peteet Mariculture Center, Gulf Shores, Alabama. The average weight gain for individual trout was greater in freshwater ponds than in brackish water ponds; however, overall production was less and mortality and food conversion higher. The conclusion is that brackish water provides a buffer to unseasonable warm weather; this buffer does not exist in freshwater ponds in south Alabama.
