Abstract
A total of 360 juvenile Anabas testudineus of mean weight (2.88 ± 0.02 g/fish) were randomly distributed in triplicate of 20 fish per tank. Acacia mangium leave meal (AM) and yeast-fermented Acacia mangium leave meal (FAM) were used at 0, 2.5, 2.5, 5, 7.5, and 10 % supplemental in the experimental diets. They were fed for 12 weeks to A. testudineus fingerling stocked in 18 plastic tanks (200 liters) set up to recirculation system. Results indicated that the final body weight, weight gain, FCR, SGR, and PER were the best in treatment 4 (FAM 5.0%), significantly different (P < 0.05) from other FAM and AM treatments. There was no significant difference (P > 0.05) in HSI, FR, VSI, L*, a*, and b* across the test diets. The hematological indices' result showed no significant difference(P > 0.05) in hematocrit and red blood cells among the experimental groups. However, the thrombocyte and lymphocyte were significantly different (P < 0.05) in experimental diets FAM 5.0% and FAM 7.5% compared to AM 2.5%, FAM 2.5%, and FAM 10%. The study showed that the inclusion of yeast-fermented Acacia mangium leave meal (FAM) at 5% had the best-enhanced growth performance and feed utilization without any adverse effect on the fish carcass quality and hematological indices.
