EFFECTS OF ORGANIC FERTILIZER AND SUPPLEMENTARY FEEDS ON GROWTH PERFORMANCE OF SILVER CARP (HYPOPHTHALMICHTHYS MOLITRIX) AND BATA (CIRRHINUS REBA) FRY IN NURSERY PONDS

Experiment was conducted to evaluate the effects of an organic fertilizer and supplementary feeds on the growth performance of silver carp(Hypophthalmichthysmolitrix ) and bata (Cirrhinusreba) fry for a period of 90 days.It was carried out under 3 (three)treatmentswere consisted of mustard oil cake (T1), cow dung (T2) and rice bran + mustard oil cake (T3) with each three replications. The fries were initially fed at the rate of 30% of body weight and it was reduced to 15% gradually. The rate of cow dung application was 988 kg/ha. During the experimental period, the water parameters werein suitable range.The average weight gain of silver carp and bata in T3 (4.69±0.17 g and 2.05±0.08 g) was significantly ((p
