This trial used a Completely Randomized Design which was carried out in 15 aquarias sized of 60 x 60 x 50 cm. Triplicate group of nile tilapia (initial body weight 12,04 ± 0,38 g fish-1 ) were fed five isonitrogenous and isocaloric feeds. The control feed was containing soybean meal, whereas in other four feeds, LLM directly replaced soybean meal with the inclusion level of 8, 16, 24 dan 31 % within the feed formulation. Result showed that the growth performance and feed efficiencies of feed containing 8, 16, 24 and 31 % LLM on the formulation were significantly lower compared to control feed. LLM was able to consumed by nile tilapia although there was a tendency of decrease of the feed consumption with the increase of LLM inclusion.
