Water Quality in the Maintenance of Oreochromis niloticus through Environmentally Friendly Biofloc Technology

This Population growth that continues to increase demands continuous availability of food. Aquaculture is one of the sectors of food production which has the highest growth rate in the world. Facing this opportunity, aquaculture is faced with several challenges related to limited natural resources such as water and land, as well as waste water from aquaculture. Furthermore, the application of best aquaculture practices in aquaculture product certification requires environmentally friendly aquaculture practices. Oreochromis niloticus tilapia is a type of freshwater consumption fish and is now a popular pet fish in freshwater ponds in Indonesia. This study aims to analyze water quality in the maintenance of Tilapia through environmentally friendly Biofloc technology. This research method was designed in the form of Research and Development. The results showed that the water quality was proper for pond operation using minimal water exchange, the development of dense microbial populations through the management of microbial populations could control the concentration of ammonia in the water. Bacteria in ponds form biofloc, producing microbial proteins that make it possible to recycle unused feed protein, so as to minimize pollution.
