<![CDATA[ABSTRACT This research was conducted to evaluate the effect of the diet containing probiotic on Nile tilapia, Oreochromis niloticus. Fish with an initial body weight of 3.62±1.33 g were fed on diet supplemented with either 0%, 10%, 15%, 20% of probiotic. Results showed that fish fed on the diet supplemented with 15% of probiotic had the highest protein retention and specific growth rate, which were16.48±0.49% and 17.65±0.9%/day respectively. Keywords: probiotic, Azola meal, protein retention, specific growth rate ABSTRAK Penelitian ini bertujuan untuk mengevaluasi efek pemberian pakan mengandung probiotik pada ikan nila, Oreochromis niloticus.
