标题：Growth Performance, Gonadal Weight and Fecundity: A Comparative Study of Rastrineobola argetea and Roasted Soybean Meal as Protein Ingredients for Brood Stock African Catfish (Clarias gariepinus) in Uganda
摘要：Rastrineobola argetea (fishmeal) was compared to roasted soybean meal as protein ingredients for brood stock African cat fish (Clarias gariepinus) in March 2019 on Geossy farm, Uganda. The fish were observed for growth and reproductive indices. Brood stocks of average weight 327 g were fed on different feeds for a month. Feed A contained soybeans as the sole main protein source. Feed B contained fishmeal as the sole protein source. Feed C was the control (usual farm feeds). Growth indices of B were significantly higher than of A (p = 0.0001, P < 0.05). It is implausible to substitute fishmeal 100% by soybean meal even with heat treatment to remove ant nutritional factors. Fish meal has essential amino acids and fatty acids that are not in soybeans, soybeans can best be used in combination with fishmeal but the most economical ratios need more research. The reproductive indices had no significant differences for feed A, B and control. Replacing fish meal with soybeans had no significant effect on the reproductive indices. Fish meal increases the growth indices and the gonadal weight of Clarias gariepinus, soybean meal is good during brood stock management because it increases fecundity although lighter eggs are observed.
