Optimization of growout diets for red drum, Sciaenops ocellatus
Because of the high costs associated with feed inputs, as well as increased concern about waste production on fish farms, there is considerable interest in developing growout diets which are both cost effective and low polluting. In two 12-week growth trials, the response of subadult red drum, Sciae...

| Summary: | Because of the high costs associated with feed inputs, as well as increased concern about waste production on fish farms, there is considerable interest in developing growout diets which are both cost effective and low polluting. In two 12-week growth trials, the response of subadult red drum, Sciaenops ocellatus, fed either a diet of 440 or 360 g pro-tein kg–1 diet (44 % or 36%) with varying E:P ratios were tested. In the first experiment, five diets containing 440 g protein kg–1 diet and one diet containing 360 g pro-tein kg–1 diet (reference) were offered to red drum (mean initial weight of 186 g). The five test diets contained 83, 103, 123, 143, and 163 g lipid kg–1 diet, resulting in E:P ratios ranging from 34.3 to 38.9 kJ g protein–1. In experiment 2, five diets providing 360 g protein kg–1 diet and one diet |
