Substitusi Tepung Ikan Dengan Tepung Bekicot (Achatina Fulica) Dalam Pakan Terhadap Pertumbuhan Ikan Patin (Pangasianodon Hypophthalmus)

---

The striped catfish (Pangasianodon hypophthalmus) is one of the freshwater fish commodities with high economic value and is widely favored by local communities. Feed is one of the most important factors influencing the growth and survival of aquaculture organisms, accounting for approximately 60–70% of total production costs. To reduce feed production expenses, it is advisable to utilize locally available raw materials capable of replacing fish meal while maintaining balanced protein content. In this study, snail (Achatina fulica) meal was used as a substitute for fish meal. This research was conducted from July to August 2025. Feed ingredient preparation and formulation of the experimental diets were carried out at the Fish Nutrition Laboratory, Faculty of Fisheries and Marine Science, University of Riau. The study aimed to determine the effect of using snail meal as a substitute for fish meal and to identify the optimal substitution percentage on feed efficiency and the growth performance of striped catfish (P. hypophthalmus). An experimental method with a Completely Randomized Design (CRD) consisting of five treatments and three replications was used. The treatments were fish meal substitution with snail meal at levels of 0%, 25%, 50%, 75%, and 100%. The test feed was administered at 10% of the fish biomass, three times daily (08:00, 13:00, and 16:00) for 56 days. Feed digestibility was measured using aquaria measuring 60 × 40 × 40 cm, with a stocking density of 15 fish per tank. Chromium oxide (Cr₂O₃) was added to the test feed at a concentration of 0.5%. Feces were collected for the analysis of Cr₂O₃ and protein content. The best results were obtained in treatment P3, which contained 75% snail meal substitution, resulting in feed digestibility of 64.66%, protein digestibility of 74.82%, feed efficiency of 36.36%, protein retention of 20.78%, specific growth rate of 3.75%, and 100% survival rate. The recordedwater qualityparametersduring thestudy were temperature 27.5–28.5 °C, pH 6.7–7.2, and dissolved oxygen 4–4.5 mg/L.
