As various environmental problems arise, the primary industry of concentrated fisheries is also promoting environmentally friendly production. In addition, due to climate change, the frequency of meteorological disasters is increasing and productivity fluctuations and damages are incurred, which leads to energy saving for industry and development of eco-friendly technologies all over the world.

Renewable energy is used by changing new energy such as fuel cell, hydrogen, coal liquefaction, gasification, and gasification of heavy acid, or by converting renewable energy such as solar, solar, bio, wind, hydro, ocean, waste, and geothermal energy. Refers to the energy used. Therefore, the use of fossil fuels to cope with climate change should be minimized, and the combined use of appropriate renewable energy by region using the solar energy and terrestrial heat or sea water heat (sea water heat) should be able to be applied to the agriculture and fisheries industry.

At present, aquaculture by-products in terrestrial tanks or closed cages act as environmental and marine pollution loads, so they need to be minimized by treating or reusing them. Plant plants and facility agriculture use carbon dioxide and nutrients (fertilizer) for photosynthesis. This is necessary and increases the cost and carbon emissions of transport fisheries when transported over long distances. In order to cultivate various crops in land planting facilities, electric cooling or heating boilers using electricity or diesel are used.

However, since such energy is expensive and environmentally undesirable, it is desirable to actively use unused energy that is environmentally friendly and unlimited in order to fundamentally solve the depleted energy use and the resulting environmental problem. . Unused energy is used differently depending on the type, form, and method of use, and a heat pump is mainly used as an energy source conversion facility.

It is possible to use heat up to -2 ℃ lower than river water. In addition, it has a temperature difference of 5 ~ 10 ℃ from the air during heating and cooling (5 ~ 10 ℃ lower than the air in summer and 5 ~ 8 ℃ higher than the air in the winter), so it is very excellent as a heat source of heat pump.

On the other hand, the land has been mainly cultivated (cultivated), but the demand for land cultivated (cultivated) of marine life as a raw material of food, food, cosmetics or bio-energy. Cultivation facilities are also required for this purpose, but development of a cultivation system that is advantageous in terms of energy and environment is needed.
