This study aimed to determine the effect of duckweed and fish meal on feed on the growth and survival of Nirvana tilapia (Oreochromis niloticus). The tested tilapia were 8-10 cm long and weighed 12 g, kept in 9 aquariums (120 cm x 50 cm x 40 cm), three aquariums as control, three aquariums for treatment A and three aquariums for treatment B, with each each treatment A. 5% dry duckweed and fish meal (1 kg commercial feed, 25 g dry duckweed and 25 g fish meal), treatment B. 5% wet duckweed and fish meal (1 kg commercial feed, 25 g wet duckweed and 25 g g of fish meal) and treatment K (control) without treatment. The results showed that dukweed and fish meal could be used as additional feed for fish. Of the three feeds that gave the best growth, treatment A 5% (dried duckweed and fish meal) had a specific growth rate of 1.7% with a daily growth rate (GR) of 0.32 grams, and an absolute length of 3.16. cm with a survival rate of 99%.
