- Abstract
Oscar, Astronotus ocellatus, is one of the popular and costly ornamental fishes. The fish has become popular among aquarium keepers due to its natural beauty. Experiments were conducted to find out optimum stocking density and protein requirement in diet of the fish. In experiment, the juveniles (length 1.3 ± 0.03cm; weight 0.23 ± 0.02 g) were fed four different diets such as goat heart, beef heart, commercial feed and specially designated diet (COF diet) for a period of 60 days. The commercial feed showed significantly higher weight gain (728.58 ± 3.69), specific growth rate (1.52 ± 0.06), protein efficiency ratio (2.21 ± 0.25) and the condition factor (6.40 ± 0.84) than goat heart and beef heart. The survival of juvenile A. ocellatus was not significantly different among the diets. The study indicated incorporation of 50% crude protein in diet and stocking the fishes at low density of 0.2 fish L-1 found to be optimum for better growth, survival and feed utilization of juvenile A. ocellatus.
