Abstract:
Growth of common carp fry was observed in different groups - in groups fed on artificial plankton diet, on supplemental feed like rice bran and mustard oil cake, and in a group directly fertilized in a tank. The observation was made over a period of 45 days. The daily growth rate, average body weight and condition factors were significantly higher in the artificial plankton fed group compared to rice bran and mustard oil cake, and direct tank fertilized group. The latter two groups were not significantly different from each other. Better growth of common carp fry, fed with artificial plankton was attributed to high dietary values, enzyme content and better water quality parameters. It is concluded that artificial plankton can be used as effective fry food, for rearing of common carp fry, in nursery ponds.
