Aquaponics it is the marriage of aquaculture (raising fish) and hydroponics (the soil-less growing of plants) that grows fish and plants together in one integrated system. The fish waste provides an organic food source for the growing plants and the plants provide a natural filter for the water the fish live in. the micro nitrifying bacteria. They do the job of converting the ammonia from the fish waste first into nitrites, then into nitrates and the solids into vermicompost that are food for the plants. The hydroponics provide 80% water efficient than the traditional agriculture. The system could be close to the market to avoid transportation as cost and pollution. Also the system could establish in desert to give the chance for green the farmland. Limited labor needed for the system but most trained is recommended. In sunny countries like Egypt, the source of renewable energy could be used to operate the mechanical equipment or even for the desalination unite
Heliopolis University applied to be an integrated environmental project provides three basic elements WEF Nexus of Water, food and energy.
The university’s aquaponic applied as integration of three Erasmus projects aimed to energy efficiency, water and agriculture. Heliopolis University is a leader in the field of aquaculture using solar energy as research project more than economic benefit, provide all the services and technical assistant to the researchers.
