Description:
Clarias gariepinus juveniles 6.35 ~C 0.22 g weight were fed five different commercial diets for 105 days to determine growth rates. Diets were hand distributed in triplicate groups of 30 fish once daily. The diets used were Coppens, Multifeed, Eurogold, Vittal and Ajanla feeds. At the end of the experiment, the final mean weight for Coppens, Multifeed and Eurogold were 181.54 ~c 0.63 g, 179.92 ~c 0.95 g and 139.92 ~c 0.26 g respectively, while final mean weight for Vital and Ajanla were 110.11 ~c 0.23 g and 119.03 ~c 0.35 g respectively. The statistical analysis of the results showed that there were significant differences (P〈0.05) in the mean final weights. Also there was no significant difference (P〉0.05) in the mean final weight between Coppens and Multifeed. The specific growth rates (SGR) were 3.19% day-1 3.18 % day-1 and 2.94% day-1 for Coppens Multifeed and Eurogold respectively and 2.71% day-1 and 2.78% day-1 respectively for Ajanla and Vital. There were significant differences (P〈0.05) in SGR among treatments and no significant difference (P〉0.05) between SGR of Coppens and Multifeed. Based on these findings, it was concluded that feed with macronutrient combinations of 45% CP, 12% crude fat, crude fiber, 1.5%, Ash 9.5% promoted better growth rates in C. gariepinus juveniles as compared with other combinations.
