Abstract
A suitable feeding program for juvenile barramundi (Lates calcarifer) includes rotifers (Brachionus plicatilis) and Artemia sp. nauplii for larvae, followed by dry starter and production feeds for juveniles. When 9–62-g barramundi were fed similar diets containing 9.3 and 12.9% fat, daily ration (2.4%) and growth (2.5%) were similar, but feed conversion ([dry weight of feed eaten]! [wet fish weight gained]: 0.93 and 1.01 for the low- and high-fat diets, respectively) was significantly lower (P < 0.05) with 12.9% fat. When 15–71-g barramundi were fed a series of six dry diets, the feed containing the most fish meal (60%) and fat (16.9%) produced the best feed conversion (0.89); however, a diet containing 20% fish meal and 13.4% fat gave practically the same results. When 74–150-g fish were fed one or two meals a day, daily growth was similar (1.7%), but daily ration (1.9% for one meal and 2.0% for two meals) and feed conversion (1.09 and 1.21, respectively) were significantly lower (P < 0.05) with...
