Reproduction induite chez les silures de l’espèce Clarias gariepinus dans la région de Kisangani, République Démocratique du Congo

This investigation aimed to test the response of female after injection of pituitary extracts collected from the male of Clarias gariepinus and the nutritional effect of two diets that one from animal proteins (diet A) and another from vegetable proteins (diet B) on survival and growth of larvae from the induced reproduction. During 21 days, the larvae were fed with these two diets containing 40% of protein, 11.61 Kj.g-1 and 12.71 Kj.g-1 of energy respectively for diets A and B in order to know the effects on survival and growth of juveniles. The findings showed that the induced reproduction used for this work is interesting as to the response of female to injection of the pituitary extracts (100%) and to hatching rate from aquatic plants used as support (hyacinths). Furthermore, the results showed that the food used from local products is acceptable for the growth of larvae from their first age. On the other hand it appears that there’s no significant difference between these two diets (A and B) although the diet A from animal proteins appears as the best compared to diet B from vegetable proteins.
