Water Quality - Opis:
- This research aims to determine the optimal stocking density for the water quality of tilapia in a round container with current and venturi aeration system. Research was conducted at the Aquaculture Laboratory Building 4th, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. The research method was carried out experimentally using the Completely Randomized Design (CRD) method consisting of three treatments with five replications, namely stocking density treatment with 15 fish, 22 fish, 30 fish using 15 L water in a container. The fish used are 3-5 cm of tilapia fry. Fish were treated for 40 days. The feed given is 5% biomass which is updated every 10 days. The parameters observed were water quality consist of temperature, dissolved oxygen (DO), pH, ammonia levels which were measured every 10 days. Based on the research results, it was concluded that the best treatment was stocking density of 15 fish/15 L in a round container with current and venturi aeration system with an average temperature of 26 °C, dissolved oxygen of 5.62 mg/l, pH of 7.09, ammonia levels 0.007 mg/l.
