Pengaruh Pemberian Probiotik Em4 dengan Dosis dan Feeding Rate Berbeda terhadap Pertumbuhan dan Kelangsungan Hidup Ikan Lele Sangkuriang (Clarias gariepinus)

Abstract

Sangkuriang catfish (Clarias gariepinus) is a fish species that is widely cultivated to meet the needs of animal protein. The market demand for freshwater consumption fish is increasing, one of the most popular fish in the market at the moment is the sangkuriang catfish. The purpose of this study was to determine the effect of giving EM4 probiotics with different doses and feeding rates and to find out the best doses of EM4 probiotics and different feeding rates on the growth and survival of sangkuriang catfish. This study used a randomized block design (RBD) with 2 treatments and 3 replications. The treatment carried out in this study was the addition of EM probiotics 4 ml/kg of feed (P1), the addition of probiotics 6 ml/kg of feed (P2), the addition of probiotics 8 m/kg of feed and feeding rates with 3 levels, namely 3% (F1), 4% (F2), 5% (F3). This research was conducted for 60 days of rearing to determine the increase in length, increase in weight, feed conversion ratio (FCR), survival rate (survival rate), and water quality. The results showed that the administration of EM4 probiotics with different feeding rates had highly significant results (P≤0.01) for weight gain and significantly different (P≤0.05) for length gain and significantly different (P≤0.05) for feed conversion ratio. In this study the P3F3 treatment (Probiotic 8 ml/kg of feed with a feeding rate of 5%) was the best treatment for the growth and survival of sangkuriang catfish (Clarias gariepinus)
