WWW.WAS.ORG • WORLD AQUACULTURE • SEPTEMBER 2017 67 holding cell of the split pond. Following 142 days of feeding during a relatively mild Alabama winter, using a feed with 45 percent protein and 19 percent fat, trout were harvested in April. Total production was 1102 kg/ha with a survival rate of 77 percent. The main cause of mortality was thought to be predation by solitary eagles. The purpose of the production trial was to determine whether Alabama’s mild winters would permit the growth of rainbow trout to a marketable size. The average size of the harvested trout was 500 g, which is considered marketable by processors. This double-cropping feature of a split pond on an inland shrimp pond could have further implications for catfish producers wishing to single-crop catfish in summer and grow rainbow trout in winter.
