Utilization of Fermented Coconut Epidermis Using Oncom Mushroom (Neurospora sitophila) on the Growth Performance of Red Tilapia (Oreochromis niloticus) Fingerlings

This study aims to analyze the effect of feed based on coconut husk waste fermented Neurospora sitophila growth red tilapia, and determine optimal dose waste. research was carried out in May – June 2021, at Aquaculture Laboratory Building IV, Faculty Fisheries Marine Sciences, Padjadjaran University Bandung, West Java45363 Indonesia. used a completely randomized design with four treatments replications. Treatment A (Control), B (feed containing 25% filler), treatment C 50% D 75% filler). Parameters observed were Specific Growth Rate, Feed Conversion Ratio, Survival characteristics water quality (Temperature, pH, DO, Ammonia). The results showed that C(feed filler) gave significantly different parameters SGR FCR, but not survival rates. Water parameter values ​​are good condition for tilapia. highest value 1.26%. lowest FCR 1.90. most tilapia is C.
