1 Mean Initial Weight
2 Mean Final Weights
3 Weight Gain=FW-IW
4 SGR, Specific Growth Rate=(ln FW-In IW)/time in days I 100
5 FCR, Food Conversion Ratios=feed (dry) intake (g)/wet weight gain (g)
6 PER, Protein Efficiency Ratio=average weight gain (g)/average weight of protein fed (g).
Table 3: Performance of O. niloticus fingerlings fed DF-based diets. Values represent the means of three replicates. Means in each column followed by a different letter are significantly different (P>0.05).
