To assess the effects of replacing standard feed ingredients with dried azolla on the growth, survival, and production cost of Labeo fimbriatus during the fry-to-fingerling stage.
Conducted a 75-day rearing experiment in fertilized 1,000 L outdoor circular cement tanks stocking Labeo fimbriatus fry (mean length 2.42 cm) at 30 m⁻³.
Formulated diets incorporating dried azolla powder at 10%, 20%, 30%, and 40% by proportionately replacing groundnut oilcake and rice bran alongside a control diet.
Fed fry at daily rations of 10% body weight during month one, 7% during month two, and 5% during the final 15 days.
Dietary incorporation of azolla up to 40% produced no significant difference in water quality, growth, or survival at harvest (p > 0.05).
Azolla inclusion decreased feed costs from 3.35 to 2.53 INR per 100 g biomass, representing an overall cost reduction of 24.48%.
