For 45 days we tested the effect of three treatments (T8, T9 and T11) on the growth of fingerlings with an initial mean weight of 5.91 ± 0.51g in a breeding basin. The treatments T8 and T9 are based on conventional and unconventional local by-products. The main ingredients used are fish meal, soybean meal, yellow corn and manure worms (Eisenia foetida) in the same proportions. The treatment T11 is the control (Coppens). The experiment was carried out in triplicates for each treatment. The physicochemical parameters of the water and the recorded growth performance parameters were subjected to the Analysis of Variance with a criterion (Anova1). The differences were significant at level of 5%. Statistical processing was carried out using software Statview 5.1. The main results recorded in this study indicate that the growth performance of fish was not influenced (p>0.05) by the physico-chemical parameters of the water in the different treatments. The growth rate (TCS) and conversion rate (TC) ranges obtained show no significant difference (p>0.05) for fish subjected to the treatments T9 and T11. On the other hand, there is a significant difference (P<0.05) between these two treatments (T9 and T11) and the treatment T8 for these same parameters (TCS and TC). The local treatment T9 is therefore as effective as Coppens.
