PENAMBAHAN TEPUNG RUMPUT LAUT EUCHEUMAA COTTONII HASIL FERMENTASI BIOFLOKULAN PADA PAKAN KOMERSIL IKAN NILA (Oreochormis niloticus)

This research aims to analyze the addition of Eucheuma cottonii sea weed flour from fermented bioflocculants on commercial food tilapia (O. niloticus) feed. was conducted for 50 days at Productionand Reproduction Laboratory Aquaculture Study Program, Department Fisheries and Marine Sciences, Faculty Agriculture, University Mataram. used an experimental method with a completely randomized design (CRD) consisting 4 treatment level sand 3 replications namely: P1 (commercial feed), P2 (90% feed + 10% seaweed flour), P3 (80% 20% P4 (70% feed) 30%). Parameters measured are growth data, absolute length, specific rate, efficiency, confersion, survival water quality. The data analyzed by using Analysis Of Variance (ANOVA) 5% significance level. that were significantly different followed DUNCAN test Further more, E. Cottonii bioflocculant fermentationto can increase weight length niloticus), butdoes not affect efficiency utilization, conversion ands urvival niloticus). concentration e. into is best because it 5,33 g 5,30
