EFFECT OF DIFFERENT SUPPLEMENTARY FEEDS ON THE GROWTH OF COMMON CARP (CYPRINUS CARPIO)

Abstract

The present experiment was conducted in a rectangular aquarium for three months to evaluate the growth performance of common carp (Cyprinus carpio). Growth performance of Common Carp were studied under four different feed supplements i.e. Feed contained Rice and Wheat bran (CG), Fish meal (T1), Poultry meal (T2) and waste proteins (T3). These four different supplementary feed were supplied to fish which were kept in four different tanks at Aquarium (Fisheries Lab) in Zoology department UAJ and K Muzaffarabad, at the rate of 0.25 gm/per day. Initially, at the time of stocking, the morphometric characteristics, viz, average body weight and average body length was measured. After initiation of experiment, these morphometric characteristics as well as physico-chemical parameters (pH and water temperature) of the water were recorded on daily basis throughout the study period. Average Body weight of Common Carp was recorded as, 13.91±1.592, 10.88±0.617, 11.96±0.967, 10.841±0.725 gm under treatment T1, T2 and T3 and Control group respectively. The final body weight of fish in Control group and treatment groups showed that fish kept in T1 (P-Value=0.003) have gained the maximum body weight, while other treatment groups showed no significant statistical difference. Final Body Length of Common Carp was recorded as 7.44±0.169, 11.28±1.407, 8.031±0.473, 9.293±1.490cm under Control group, T1, T2 and T3, respectively. The final body length of fish in Control group and treatment groups showed that fish kept in T1 (P-Value = 0.001) gained more length followed by T3 (P-Value = 0.007). There is no significant statistical difference in Control group and T2. These results suggest that T1 containing the 30% wheat and rice bran supplementary diets can increase the fish maximum body weight and body length.
