dc.description.abstractIn the present investigations, the experiment was carried out in .0033 ha.sized ponds at the fish hatchary farm of CCSHAU, Hisar for 150 days to study the effect of vermicompost as pond fertilizer on growth performance of common carp. The different organic fertilizers viz. Vermicompost @10000kg/ha/yr, vermicompost @ 5000kg/ha/yr and cowdung @10000kg/ha/yr were used to monitored their effect on water quality parameters and fish growth. One forth dose of fertilizers were applied 15 days prior to fish stocking and remaining doses given at fortnightly interval. The fry/fingerlings were stocked @ 10000/ha/yr and fed upon supplemented feed given at 5% of their body weight. The water parameters like DO, pH, K, P and NH4-N was found in optimum range in all treated ponds and observed maximum value under the vermicompost @ 10000kg/ha/yr. The range of pH(7.90 +0.016 – 8.19+0.007 mg/l), Dissolved oxygen (7.136+0.012 – 7.22+0.01mg/l), Potassium (18.392+0.027 – 22.688+0.014mg/l), Phosphorous (0.137+0.001 - 0.166+0.001mg/l) and NH4-N (0.107+0.0 - 0.127+0.001mg/l) increased significantly(P<0.05) in the ponds received vermicompost @ 10000kg/ha/yr. As vermicompost easily and large amount of nutrients( N,P,K) release in water due to which plankton production also found to be highest in ponds treated with vermicompost @ 10000kg/ha/yr. Growth of fishes also observed maximum where the plankton population was maximum. So, it is concluded that vermicompost @ 10000kg/ha/yr shows maximum growth of fishes followed by vermicompost @5000kg/ha/yr and cowdung @10000kg/ha/yr. There is three times more growth of fishes occurred in vermicompost @ 10000kg/ha/yr as compare to control where no fertilizers were used. All the observed data statistically analysed by using completely randomized design (CRD) at 5% level of significance.en_US
