The growth of tilapia that is cultivated in moving water has very significant growth but tilapia that is cultivated in tarpaulin ponds with still water can also develop quickly, provided that its cultivation uses EM4 technology.
This is proven in the trials of tarpaulin ponds owned by PT. PLN (Persero) P3B Java Bali, with the application of EM4 technology, the cultivated tilapia looks healthy and has a fast growth rate. As revealed by one of the managers of the State Electricity Company CSR program, H. M Basuki, the use of EM4 Fisheries in tarpaulin ponds is very beneficial including being able to increase the body’s defences of fish so as to reduce the use of antibiotics, increase growth and size of fish, increase immunostimulant and energy efficiency and water quality management “Not only that, the use of EM4 can ferment the remainder of the feed, dirt, at the bottom of the pond and decompose ammonia, methane and hydrogen sulfide (H2S) gases so that it can increase dissolved oxygen (DO) and the water becomes clean and there is no need for repeated water replacement,” he said.
What is clear, with EM4 technology we can maintain the environmental quality of aquatic biota and is safe as well as environmentally friendly. For Basuki, the superiority of this tarpaulin pond is a good opportunity for the development of tilapia aquaculture. Tarpaulin ponds can be applied for tilapia hatchery, nursery and enlargement to produce tilapia consumption and as a mother. The use of EM4 Fisheries can also be applied during the processing of tarpaulin ponds or during maintenance.
