abstract
Effects of Various Lipid Sources on growth and survival of Oscar, Astronotus Ocellatus Juveniles was evaluated. Each diet was prepared to contain 40% protein and a lipid source. In experiment, the juveniles (Length 1.8 ± 0.04 cm; Weight 0.03 ± 0.01g) were fed six isoenergetic and isonitrogenous diets viz., sardine oil + linseed oil (T₁), sardine oil + soybean oil (T₂), sardine oil + mustard oil (T₃), cod liver oil + linseed oil (T₄), cod liver oil + soybean oil (T₅) and cod liver oil + mustard oil (T₆) for a period of 60 days. The experiment was designed as per completely randomize design with four replicates for each combination of oil sources. Among the experimental diets, the diet incorporated with sardine oil + mustard oil showed significantly higher growth such as length gain (220.25 ± 0.11), weight gain (440.96 ± 0.14) and specific growth rate (2.80 ± 0.04) and survival. The feed utilization such as protein efficiency ratio (20.04 ± 0.61) and lipid efficiency ratio (114.53 ± 0.35) were significantly higher than other diets, whereas feed conversion ratio (0.13 ± 0.01) significantly lower than other diets.
