    Effect of different dietary sources on the rearing of Amur carp (Cyprinus carpio haematopterus)
    (CCSHAU, Hisar, 2021-09) Shahi, Sudha; Gajender Singh
    In present study, different types of feed were incorporated in diet included T1 (live feed), T2 (live+formulated feed), T3 (formulated feed) and commercial feed as a control treatment (Tₒ) to assess the effect of different dietary sources on the rearing of Cyprinus carpio haematopterus fry for three months. 180 fry having initial weight and length (.25 gm and 2.08 cm) were recorded and divided into 12 groups having 15 fries in each treatment tank. The growth parameter and water quality parameters were measured at fortnight intervals. The study showed that all the growth parameters were found significantly (p=0.05) increasing throughout the experiment period. The maximum weight and length were observed in T2 treatment i.e. (5.31±0.01) gm and (5.25 ±0.02) cm and minimum weight and length were observed in control treatment Tₒ i.e. (3.37±0.04) gm and (3.10± 0.10) cm. SGR, DWG, and ADG were found maximum in T2. The FCR of (1.30±0.05) was found best in treatment T2. Various physicochemical parameters (DO, pH, electrical conductivity, total alkalinity, total hardness, calcium, magnesium, chloride, and ammonia concentration) were ranged within the tolerance level in the experimental period. At the end of the experiment carcass composition analysis showed maximum protein of (49.67±0.66) % and fat of (25.33±2.33) % in T2 treatment. The result of the experiment depicted that incorporation of a mixed diet of live feed and formulated feed completes the nutrient requirement for the rearing of Cyprinus carpio haematopterus fry
