The high cost of fish feed these days leads the developing countries such as Cameroun to use inexpensive and cheap local by-products. However, their source and or their conservation could generate mycotoxins affecting the performances of fish production. This work was carried out from January to June 2014 at the teaching and research farm of the University of Dschang, consisted to evaluate the effect of local feed contaminated with aflatoxine B1 on the production performances of Clarias gariepinus. To do this, 270 fry (4±2g) distributed in three treatments T1 (10 ppb), T2 (17 ppb) and T3 (20 ppb) and in triplicat (30 fry/tank of 1m3) and feeded of 5% of lichtyobiomass-fed daily were used. The high source of aflatoxin B1 in each treatment was from contaminated chicken dropping. Aflatoxine B1 has negatively affected (P<0,05) the growth characteristics regardless of its rate in the food. These effects increase with the rate of aflatoxin B1 contained in food. Moreover Otherwooooo, the contamination rate at 10 ppb could be acceptable despite its overweight K (0,40±0,20) because this treatment show the best growth performances (weight Gain (35,40±11,62g), Specific Growth Rate (1,46±0,24), Consumption Index (2,01±0,7)). No significant effect of aflatoxin B1 bio-accumulate in the fish tissue was observed, it is same for the hematologic parameter considered and survival. The presence of aflatoxin B1 in the local feed affects growth of Clarias gariepinus fry and the extension of this study on fish reproduction could significantly improve fish production.
