Evaluasi Azolla microphylla Sebagai Bahan Pakan Tambahan Terhadap Pertumbuhan Ikan Nila (Oreochromis niloticus)

Abstract

This study aims to analized the growth rate, survival rate, and conversion ratio of Tilapia (Oreochromis niloticus) feed in the addition of Azolla microphylla feed and pellet administration in all treatments. This experiment aims to test the consumption of Azolla microphylla on freshwater Tilapia (Oreochromis niloticus) which is cultivated in a controlled system with oxygen, temperature, Ph, ammoniac. Fish performance is shown by growth and survival rate of fish. A completely randomized design (CRD) with three treatments, P1 (pellet 3%); P2 (pellet 4%) P3 (pellet 3% + Azolla add libitum); P4 (pellel 4% + Azolla add libitum). The results showed that weight growth was significant (P <0.05), and length growth, fish specific growth, feed efficiency were significantly different (P <0.05)
