THE EFFECT OF SUBSTITUTION OF SUCKERMOUGHT CATFISH FLOUR WITH LOCAL FISH FLOUR IN ARTIFICIAL FEED ON SURVIVAL AND FCR OF NILE TILAPIA

Feed is a key component in the success of fish farming.However, there is a problem in the cultivation process, namely that raw materials for feed are still imported, resulting in high feed prices for production costs.So that alternatives are needed to overcome these problems, one of which is utilizing available local raw materials that do not compete with human needs, one of which is suckermouth catfish flour.The purpose of this study was to determine the effect of substituting suckermouth catfish flour as a substitute for local fish flour in artificial feed on tilapia production.This study was conducted in January-February 2025, located at the Unhas Education Pond, Bojo District, Barru Regency, South Sulawesi.This study used a completely randomized design (CRD) with 5 treatments and 3 replications, so that there were 15 research containers filled with 15 test animals weighing 3 grams/head.The treatments given were treatment A = 100% local fish meal and 0% suckermouth catfish meal, treatment B = 75% local fish meal and 25% suckermouth catfish meal, treatment C = 50% local fish meal and 50% suckermouth catfish meal, treatment D = 25% local fish meal, 75% suckermouth catfish meal, and treatment E = 0% local fish meal, 100% suckermouth catfish meal.Data were analyzed using a comparison of the mean analysis of variance (ANOVA).Based on the results of the study, the treatment with the best value on the survival parameter was treatment D and the best treatment on the feed efficiency and FCR parameters was E with a survival value (84.33 7.50a), feed efficiency (4.62 0.60) and FCR (2.70 0.17b).The results of the water quality analysis showed temperature results with a value of 27-28 and pH with a value of 7.2-77.
