Effect of pH on growth performance and survival rate of Grass Carp
Journal Title: Scholars Academic Journal of Biosciences - Year 2013, Vol 1, Issue 7
Abstract
Grass Carp fingerlings averaging 19.0 ±1.0 g in weight were stocked for 60 days at different PH levels. The experimented Carp were fed with diet containing 26.58% crude protein. The total water was changed twice daily. Growth and survival of common carp was recorded at 15 days interval. Results showed that growth performance was significantly decreased at PH 6 and 9, while the difference between PH 7 and 8 were not significant (P>= 0.05). No mortality occurred during the experiment. Feed conversion ratio (FCR) increased at PH 6 and 9, since at the PH 6 value was significantly higher than PH 9. It was concluded that water PH 7-8 could be more suitable to Grass carp culture for optimum growth performance and survival rate. Keywords: Grass Carp, PH, performance, survival rate
