However, its availability is limited due to the overexploitation of capture fisheries and its price continues to increase each year. The replacement of fishmeal with less expensive energy-rich feed ingredients is necessary for the sustainable development of aquaculture. The objective of this study was to evaluate the effects of different levels of the digestive juice of the snail Archachatina ventricosa in carbohydrate-rich diets on the growth performance and intestinal glycosidase activities of Nile tilapia (Oreochromis niloticus) Materials and Methods: Five experimental diets (R-0, R-1.5, R-2.5, R-5 and R-I) were formulated based on different levels of snail digestive juice (0, 15, 25 and 50 mg g1). The diet R-I contained 5% inactivated digestive juice. O. niloticus fingerlings with an initial body weight of 22.55±2.29 g reared in glass hatchery tanks were fed with the experimental diets for 56 days. Results: The daily weight gain (DWG), specific growth rate (SGR), feed conversion rate (FCR), protein efficiency ratio (PER), intestinal glycosidase activities and fish body composition were significantly (p<0.05) influenced by the digestive juice. The DWG, SGR, FCR and PER were higher in the fish fed with the diet R-5. The 2.5% digestive juice was shown to have high invertase activity in the intestines of the fish. Conclusion: This study showed that the incorporation of 5% digestive juice from the snail A. ventricosa in experimental diets containing 40% carbohydrates improved growth in juvenile tilapia, O niloticus. The determination of the optimum content of the digestive juice enzyme would better use this ingredient in the formulation of carbohydrate-based fish feeds.]]>Tacon, A.G.J. and M.
