||The present study aims at determining the optimal and maximum quantity of the flour of worm of manure E. foetida in the feed of fingerlings of O niloticus.
The experiment has been carried out of basins square of 1m3 of volume during 45 days from October at November 2016. During the period of acclimatization which lasted three days the fingerlings of initial average weight 4.79 ± 0.23 g have been nourished with Coppens. They have been then subjected to five treatments (T0; T5; T10; T15 and T20 corresponding to contents of 0%; 5%; 10%; 15% and 20% of flour of worm of manure in feed.
At the end of the experiment the final average weights calculated was in the between 33.18 ± 13.71 g and 56.70 ± 14.65 g according to treatments'.
Thus, the variance analysis with single direction (Anova1) with Statview 5.1 indicates that no significant difference exists between the various rates of survival. However, a significant difference between the various specific growth rates (from 3.45 ± 0.31%/day to 6.67 ± 0.30%/day) was observed.
According to the mathematical model (amount-answer) based on the polynomial regression of the second degree, the maximum rate of incorporation of the flour of worm of manure in feed of fingerlings of O niloticus high out of basin under the conditions of this study was 13,82%.
