Effect of feeding frequency on growth and survival rate of Clarias gariepinus fingerlings reared in plastic bowls
The effects of feeding frequency on feed intake, growth and survival rates were determined in C. gariepinus. Twenty fish per tank (bowl) were stocked in triplicate. They were fed once (1D), thrice (3D) and five times daily (5D) respectively. The 5D group growth rates were observed significantly different (P< 0.05) from fish fed on 1 (1D) and (3D) feeding frequency. All the treatments containing 1D, 3D and 5D were observed to have significant difference (P> 0.05) in terms of final weight (FW). There was also a noticeable increased trend in final weight (5D > 3D > 7D). Feed conversion ratio (FCR) of 3D and 5D treatments were higher than 1 D) treatment (P< 0.05). According to the results, feeding C. gariepinus 1 time daily (1D) did not influence the growth; however, 5 times daily reduced mortality and improved the feed conversion ratio (FCR) of C. gariepinus.
