With a view to year-round valuable fish farming a control system terming their breeding and growth, protected by USSR inventor's certificates and Russian inventor's patents, was developed. The management principle is fish contents in "critical" salinity along with the simultaneous thresholds "signal" factors (temperature and light) and subsequently obtaining offspring and juveniles in complex of optimal ecological conditions. For the implementation of the proposed industrial biotechnology and year-round fish farming a new installation of water recycling system (WRS) hatcheries and farms was developed by means of the underground conditioning of fish cultivation medium. Their essence is that fish farm water supply systems are additionally provided by underground, or in a half in ground large volume tank-sump tanks. Such WRC, being isolated from climate conditions, allow to conserve and use natural seasonal water resources and first consensually resolve earlier alternative volume-dependent energy problem (requiring lower volumes of water) and water purification (requiring its increasing) in septic tank-sump tanks. The basic principle of their operation is filling one tank-conditioner by "cold" water and the other by "warm" at the appropriate seasons and by additional water supply fish farm systems water circulation. Techno-economic calculation shows, that with the increasing volume of such water air conditioning heat transfer will be proportionally reduced, but productivity increases and reduces its system specific cost while maximizing reliability.
