Pengaruh Penambahan Enzim Phytase Pada Pakan Dengan Dosis Yang Berbeda Terhadap Pertumbuhan Dan Kelulushidupan Ikan Gabus (Channa Striata) Menggunakan Sistem Resirkulasi

---

Snakehead fish (Channa striata) is a freshwater species of high economic value with great aquaculture potential. However, the use of plant-based feed ingredients is limited by the presence of antinutritional factors such as phytic acid, which can hinder fish growth. This study aimed to examine the effect of phytase enzyme supplementation in feed at different doses on the growth and survival rate of snakehead fish using a recirculating aquaculture system. A completely randomized design was applied with five levels of phytase enzyme dosage (0; 1; 1.5; 2; and 2.5 g/kg feed) and three replications. Observed parameters included absolute weight and length gain, specific growth rate (SGR), feed efficiency, feed conversion ratio (FCR), feed digestibility, survival rate, and water quality. The results showed that the 2.5 g/kg phytase supplementation (P4) yielded the best performance, with an absolute weight gain of 4.68 g, length gain of 5.62 cm, feed efficiency of 67.66%, SGR of 2.7%/day, survival rate of 97%, FCR of 1.4, and feed digestibility of 63%.
