The present invention relates to a method of producing sterile aquaculture water and a fish aquaculture method using flowing sterile water and, more particularly, to a novel fish aquaculture method using flowing sterile water, in which: sterile aquaculture water is produced having a level of harmful ingredients that is lower than potable water, by producing oxidants through electrolysis treatment of fresh water or seawater for fish aquaculture using freshwater or seawater, and by killing pathogenic viruses, germs, and parasites; and a novel sterile aquaculture system (SAS) is employed which removes residual oxidants harmful to fish by neutralizing the sterile aquaculture water when farming fish by using the sterile aquaculture water, and then using the neutralized sterile aquaculture water as fish aquaculture water, so as to be able to minimize the mortality rate of fish due to various pathogenic microorganisms, while not using antibiotics and vaccines.

The invention discloses a method for self-use of a deep sea net cage by utilizing tidal power generation. The method comprises the following steps that I, diving or floating operation is started through a control platform; II, feeding is conducted through a delivery system; III, when the deep sea net cage floats upwards, a net cage can be cleaned and maintained through a cleaning system, and cleaning comprises cleaning of a camera lens of a monitoring system and cleaning of a netting; IV, a mobile client detects imaging data of water temperature, water quality, dissolved oxygen, residues and aquatic creatures through an underwater measurement and control and oxygenation system. According to the method, the problem of insufficient management initial release and storm resistance of a traditional deep sea aquaculture net cage is solved, and the deep sea net cage is managed in a floating and sinking manner, so that the damage rate caused by typhoon attack is effectively avoided. The deep sea aquaculture safety guarantee is improved, meanwhile, the deep sea aquaculture space and the adaptive sea area are greatly expanded, the offshore aquaculture ecological environment is improved, and a new chapter is opened for deep sea fishery.

The invention relates to a solar thermal-field electron emission power generation device, which comprises a solar cooker and a thermal-field electron emission power generating body. The solar thermal-field electron emission power generation device is characterized in that power generation equipment is formed by mature magnetic focusing and magnetic insulating technologies on the basis of a metal thermal-field electron emission experiment. The solar thermal-field electron emission power generation device has the characteristics of environmental friendliness, low cost and high efficiency, so that the solar thermal-field electron emission power generation device can be widely applied to units and individuals without a public power supply circuit in pasturing, sentry posts, forest protection, offshore aquaculture and the like.

The invention provides an ecological aquaculture method for sea horses. The ecological aquaculture method comprises the following steps of adding seawater which is subjected to filtration, sedimentation and regulation into a plastic barrel: the salinity of the seawater is 2.0-2.8 percent, the pH is 7.6-8.5, the oxygen dissolving amount is greater than 5mg / L, the liquid level is 70-80cm, and the temperature is 20-30 DEG C; feeding seaweeds into the plastic barrel, and keeping the fresh weight density of the seaweeds to be 1-3kg / m<3>; feeding living baits into the plastic barrel; spraying microorganism preparations; feeding young sea horses. Compared with an existing aquaculture technology, the ecological aquaculture method for the sea horses has the advantages that by the method for sea horse aquaculture, the environmental factors can be stabilized and controlled, the large-scale industrial production is facilitated, the feeding frequency of baits is reduced, the production efficiency is improved, the survival rate of the sea horses is guaranteed, and the economical benefit is high.
