The purposes of this research were to determine the best dosage of the tuna innards fermentation powder substitution based on its survival rate specific growth rate and the conversion ratio of pangasius fish Pangasius sp. fish feed. The fish feed test formula contained 30 of raw protein. The tested fish feed consisted of fish powder mixed with substitution powder from fermented tuna innards. The substitution in fish feed A0 B10 C20 and D30. The number of pangasius fish thrown into 50x30x30 cm aquarium was 20 fish with average weight 3.120.03g. Fish feeding frequency was 5 5 three times a day at 0800 1300 and 1900 for 40 days. The results showed that with the added fermented tuna innards protein powder substitution dosage until 20 of the fish feed the survival rate improved reaching 100 the best specific growth rate was at 3.36 BB and the fish feed conversion ratio declined at the lowest 1.55 gg.
