Pengaruh Pemberian Tepung Daun Indigofera (Indigofera zollingeriana) pada Pakan Komersil dengan Feeding Rate yang Berbeda terhadap Pertumbuhan Dan Kelangsungan Hidup Ikan Nila (Oreochromis niloticus)

Abstract

Fish feed is one of the factors that play an important role in the process of fish growth. Fish growth can run optimally if the amount of feed, feed quality and nutritional content are well met. One of the ways that can be done to achieve a high level of success in tilapia cultivation is to develop technology and innovation in tilapia feed by adding ingredients to fish feed that contain nutrients and high protein content in feed obtained from indigofera leaf flour. This research was conducted in March ˗ May 2023. Giving a mixture of commercial feed using indigofera flour and fishmeal with different feeding rates showed a very significant difference in weight (P≤0.01), while in length gain with feed conversion ratio also showed a very significant effect (P≤0.01), and had a very good survival rate. The interaction between feeding a mixture of commercial feed with fishmeal at different feeding rates on length had a significant effect, and on weight gain had a significant effect. With a good survival rate of 90%. Giving a mixture of commercial feed using fishmeal with different feeding rates on the optimal length and weight gain is the T3F3 treatment. And on FCR T3F3
