Effect of Vermicompost as Pond Fertilizer on Growth Performance of Common carp (Cyprinus carpio Linn.)

Fish pond fertilization is considered an important scientific discipline for increasing fish production. It increases the production of beneficial phytoplanktons which further enhances the biological productivity. The advantage of use of vermicompost as organic fertilizer is availability of nutrients in ready- to- uptake form. The research was conducted to study the effect of vermicompost as pond fertilizer on growth performance of common carp. The experiment was carried out in 0.003 ha sized earthen ponds at fish hatchery of CCSHAU, Hisar for 150 days. Different organic fertilizers viz. Vermicompost@ 10000kg/ha/yr, vermicompost @5000kg/ha/yr and cowdung @ 10000kg/ha/yr were used in five replicates. One pond was treated as control. One forth dose of fertilizers were applied 15 days prior to fish stocking and remaining doses were given at fortnightly intervals. Maximal growth of common carp was observed in the pond treated with vermicompost @10000kg/ha/yr followed by vermicompost @ 5000kg/ha/yr and cowdung @10000kg/ha/yr and lowest in the control. The treated pond with vermicompost@ 10000kg/ha/yr showed about 3 times higher growth of fishes as compared to control. All the observed data was statistically analyzed by using CRD at 5% level of significance.
