The Effect Of Feeding Waste (Offal) Tilapia On The Growth And Survival Of Catfish Fry (Clarias sp.)

Abstract

Feed is an important factor in fish farming. In addition to supporting the growth and survival of fish, feed is also one of the largest components of production costs. The purpose of this study was to determine the effect of alternative feeding of tilapia waste on the growth process of catfish (Clarias sp.) and to obtain the best dose proportion for the growth of catfish. This research was conducted in June - July 2022, at the Laboratory in Faculty of Fisheries, University 45 of Mataram. The method in this study was the experimental method and Completely Randomized Design (CRD) with a total of 4 treatments and 1 without treatment (control), 3 replications in each treatment (P0 = Commercial feed (control), P1 = (25% offal) tilapia + 75% commercial feed), P2 = (50% tilapia offal + 50% commercial feed), P3 = (75% tilapia offal + 25% commercial feed), P4 = 100% tilapia offal. Data collected namely primary data in the form of length and weight of fish and water quality in the form of temperature, pH, do and ammonia and secondary data in the form of literature, previous studies and books.The results showed that the best growth was found in P2, namely growth in weight of 0.036 grams and growth in length of 0, 66 cm with a specific growth rate of 0.036 g/day, feed conversion value 0.74 and survival 43%.Water quality during the study was 25-29°C, pH 6, 9 - 7, 0, dissolved oxygen 4.0 - 6 0.0 ppm and ammonia 0.5 – 2.0 mg/L.
