Higher water temperature enhances dietary carbohydrate utilization and growth performance in Labeo rohita (Hamilton) fingerlings

A 60‐day experiment was conducted to delineate the effect of three dietary levels of gelatinized carbohydrate (GC) on growth, nutrient‐utilization and body composition of Labeo rohita fingerlings (avg. wt 6.5 ± 0.3 g) reared at two water temperatures (ambient‐AT (26 ± 0.8 °C) and 32 °C). Two hundred...

Two hundred and sixteen fingerlings were randomly distributed into six treatments in triplicates. Three semi‐purified isonitrogenous diets were prepared with graded levels of GC viz.
