Snakehead fish (Channa striata) is a type of freshwater fish that is popular in India and Southeast Asia, including in Indonesia. The availability of snakehead fish is lower than the demand. Currently snakehead fish can be cultivated with artificial feeding. Snakehead fish is a carnivorous fish that uses more animal protein. The use of vegetable protein in snakehead fish has been carried out but is still not optimal due to the presence of phytic acid in vegetable materials which makes fish unable to digest food properly. The availability of phytase in the fish body to lyse phytic acid is very limited. Therefore, it is necessary to add a phytase enzyme to hydrolyze phytic acid. This study aims to determine the effect of adding phytase with different doses to artificial feed on growth, protein efficiency ratio, feed efficiency, feed consumption and survival of snakehead fish and water quality.This research was carried out at the Labortorium Dasar Perikanan in July – August 2021, this study used a completely randomized design (CRD) which consisted of four treatments and three replications, namely P0 (without the addition of phytase), P1 (addition of phytase 30 mg 100 g-1 material). vegetable), P2 (addition of phytase 50 mg 100 g-1 vegetable material), P3 (addition of phytase 70 mg 100 g-1 vegetable material). The size of the fish used in this study was 3-4 cm with a stocking density of 2 L-1 fish, the maintenance of the study was 30 days. The results showed that the addition of phytase 70 mg 100 g-1 vegetable material (P3) was the best result with absolute weight growth (1.49 g), absolute length growth (2.48 cm), feed efficiency (79.44%), feed consumption (37.68 g) protein efficiency ratio (2.03%), and survival (100%). The quality of water obtained during maintenance is temperature 25.1 – 29.9oC, pH 6.1 – 7.6, dissolved oxygen (DO) 4.01 – 4.90 mg L-1 and ammonia 0.02 – 0.37 mg L-1.
