Abstract
An ideal aquaculture tank would provide a natural river, lake or marine environment with an artificially clean sanitary environment that approximates the fish's natural habitat. This includes purification of culture water, temperature maintenance, oxygen concentration, running water and appropriate water depth, collision prevention, and necessary feed spraying. The creation of this artificial environment involves the use of geothermal heat and solar power for purification, aerobic, artificial running water, feed spraying, and other automatic controls and waste disposal. We report research results that enable unmanned aquaculture tanks at the ideal minimum cost.
