INCREASING GROWTH OF TILAPIA FISH (Oreochromis niloticus) USING PROBIOTICS FROM LOCAL RAW MATERIALS

Abstract

Tilapia (Oreochromis niloticus) is one of the freshwater fishery products that people
are interested in. One of the obstacles faced is the growth of tilapia which is less than optimal
so it is necessary to optimize it by giving probiotics to the feed to increase the digestibility
and nutritional content of the feed. The purpose of this study was to determine the use of
probiotics with local ingredients to increase the growth and survival rate of tilapia
(Oreochromis niloticus) seeds. The research used a completely randomized design (CRD)
method with 3 treatments and one control, each treatment had 3 replications with a tilapia
density of 10 fish/10 liters measuring 3-5 cm long. Dosage of probiotic treatment A (2
ml/10gr), B (4 ml/10gr), C (6 ml/10 gr), and Control (0 ml). The results showed that each
treatment had a significant difference in growth and survival rates. Treatment C was the best
treatment with a growth of 3.62 gr, and a daily growth rate of 0.126 gr. The survival of tilapia
seeds in the treatment and control was 100%. The water quality during the study was within a
reasonable range for the life of tilapia.
