Abstract

This study aims to find the suitable dose of Vitomolt Plus in order to reduce levels of ammonia in tilapia cultivation. This research was carried out for 1 month in August to September 2021 at Fish Hatchery Laboratory of Marine Sciences and Fisheries Faculty, Hasanuddin University. The study was conducted using a completely randomized design with 6 treatments and 3 replications. The treatments were various doses of Vitomolt Plus added in the cultivation water, including 0 ppm, 2 ppm, 4 ppm, 6 ppm, 8 ppm, 10 ppm. The juvenile of tilapia measuring about 5 cm body length stocked with 5 fish for each aquarium. Water quality like Dissolved Oxygen, Temperature, pH, Nitrate, Nitrite, and Ammonia content were measured in this study. The results showed that the addition of Vitomolt Plus in tilapia culture media affected the concentration of ammonia. In this study, 6 ppm of Vitomolt Plus treatment resulted lowest ammonia concentration on the 10th and 12th days of observation.
