Abhishek Giri and Shriparna Saxena |
Using Clarias batrachus larvae that were 5 days old and had an initial total length of 7.0 mm and a weight of 3.1 mg, an experiment lasting 21 days was conducted with live as well as counterfeit feed in an indoor incubation facility. The brooders of C. batrachus (Av. wt of female 170 g; Av. wt of male 128 g) were secured from outside lakes and loaded in a lake close to the examination site, 2-months before producing. The fishes were effectively initiated reared utilizing WOVA-FH @ 1.0-2.0 ml/kg body weight (bw) to females and 0.5-1.0 ml/kg bw to males. For the study, three artificial diets with three replications of each were used. Among such, diet 6.52% fish meal (CP 60%), 89.96% powdered milk (CP 27%), and 6.52% boiled egg yolk (CP 40%) were used to create Diet A. Diet B employing 18.73% FM (CP 60%), and 18.73% Baker yeast (CP 44.75%), 18.73% boiled egg yolk (CP 40%) and 48.80% Wheat flour (CP 18%) and 34.44 % fish meal (CP 60%), 34.44% Baker yeast (CP 44.75%) and 31.12% Whole egg (CP 12.6%) were used to create Diet C. Diat A,B and C contain 30%, 35% and 40% Crude Protein level respectively followed by Pearson Square Method.. The highest rate of growth was seen in the larvae fed diet C. The study's findings demonstrated that larvae of C. batrachus could be successfully raised on a diet composed of 31.12% whole eggs, 34.44% yeast, and 34.44% fish meal. The nature of incubation facility water was recorded for temperature 29° C, pH 7.2, DO 7.1 mgL-1 and complete alkalinity 132 mgL-1 separately.
