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.

Abstract: (french)
Ce travail a comme but de tester la réponse de la femelle après injection des extraits hypopyhsaires prélevés chez le mâle de Clarias gariepinus et l’effet nutritionnel de deux rations formées à base de protéines d’origine animale (Ration A) et de protéines d’origine végétale (Ration B) sur la survie et la croissance des larves issues de la reproduction induite. Pendant 21 jours, les larves ont été nourries avec ces deux rations contenant 40% des protéines brute, 11,61 Kj.g-1 et 12,71 Kj.g-1 d’énergie brute respectivement pour la ration A et la ration B en vue de voir les effets sur la survie et la croissance des juvéniles. Les résultats obtenus ont montré que la reproduction induite utilisée pour cette étude est intéressante quant à la réponse de la femelle à l’injection des extraits hypophysaires (100%) et au taux d’éclosion à partir des plantes des supports utilisées (jacinthes d’eau). Par ailleurs, l’analyse des résultats a montré que l’aliment à base des produits locaux utilisés est acceptable pour la croissance des larves dès leur premier âge. Les deux rations n’ont pas donné des écarts significatifs bien que la ration A formée à base des protéines d’origine animale apparait comme meilleure par rapport à la ration B formée à base des protéines d’origine végétale.
