Land-based aquaculture is one of the sea-food production systems in the specialized facility. This kind of aquaculture is located nearby human community. This aquaculture form has three kinds of water usage methods, i.e., running water system, closed recirculating system, and water pouring and recirculating system. These methods are used depending on the temperature, quantity, and quality of the supplied water. The functions that are intensive fish and shellfish production with high efficiency under artificial environmental condition, and accumulation of waste materials by recirculating aquaculture for environmental conservation are attracting a lot of attention in recent years. These functions can be used to enhance the growth of cultured fish and shellfish by controlling photoperiod, salinity of rearing water, etc. and to grow plants using the waste materials discharged from land-based aquaculture. In addition, there few location constraints and surplus energy, i.e., waste heat discharged from factories, hot spring heat, etc. can be used for aquaculture. Because of these characteristics, it can be integrated into human society and serve as a tool to bring about economic spillovers by collaborating other industries. This is expected to contribute to the development of aquaculture diversity.
