The Effect Giving of Probiotics in Water on Feed Efficiency and Water Quality for Aquaculture Tilapia (Oreochromus niloticus)

Abstract
This study aims to determine the effect of giving probiotics to water on the value of Feed Conversion Ratio (FCR), feed efficiency, and water quality of tilapia (Oreochromus niloticus) aquaculture. This is an experimental research with 4 treatments and 3 replications. The treatments tried were:
- Treatment K: Without Probiotics,
- Treatment A: given probiotics at a dose of 1 ppm,
- Treatment B: given probiotics at a dose of 1.5 ppm, and
- Treatment D: given probiotics at a dose of 2 ppm
The results showed that the water-given probiotics had an effect on the FCR value of the feed and the feed efficiency of tilapia, where the higher the dose of probiotics given, the smaller the FCR value, likewise with the value of feed efficiency, where the higher the dose of probiotics in tilapia rearing water, the higher the value of feed efficiency. The results of water quality measurements, such as temperature, pH, and ammonia, all of these water quality parameters still meet the requirements for the growth of tilapia.
