Reproductive performance of male broodstock Clarias jaensis (Boulenger, 1909) fed various dietary energy


Author(s): Tsoupou Kuété Suzy G, Efole Ewoukem Thomas and Tchoumboue

Abstract: This study aims to investigate the effects of four diets with different energy contents; 3000, 3100, 3200 and 3300 Kcal/kg, on reproductive characteristics of male broodstock Clarias jaensis. 360 male and female (97 ± 9 g) were divided into four groups, corresponding to the different diet and were breed during 5 months. Except the FSH and Hepatho somatic index, reproductive characteristics were comparable between diets (P>0.05). The higher FSH (1.15 ± 0.27 mlU/ml), LH (1.03 ± 0.18 mlU/ml), testosterone (179.67 ± 5.37 ng/ml), Gonado somatic index (0.33 ± 0.05%) and mature male (87.5%) were recorded at 3000 Kcal/kg followed by 3100 Kcal/kg, while Hepatho somatic index were higher (1.11 ± 0.14 %) at 3100 Kcal/kg. Histological inspections of gonads did reveal that fish fed at 3000 Kcal/kg had heavier and more developed gonads compared to other group. Therefore; 3000 Kcal/kg was found to be optimal for healthy gonad development.
