At present, in order to ensure the survival rate and growth quality of tilapia juveniles, the current artificial breeding method of tilapia is usually based on pond culture, while box culture is rarely used because it is often affected by the influence of the box. The sealed structure, the limitation of the water body environment and the unreasonable breeding method lead to the low breeding density of the fry, the unstable growth environment of the fry, and the disadvantages such as water pollution and disease in the breeding water, and the natural water flow environment and dissolved oxygen of the normal pond cannot be achieved. Therefore, it is still difficult to realize a large-scale and rationalized box culture method, which makes the production and usability of tilapia box culture low and the breeding effect is not good.

Abstract
A method for cultivating tilapia fry based on a closed culture container, using a closed culture container for culture, the culture method comprising: (1) configuring a culture feed according to the weight ratio of the ingredients of the culture feed formula; (2) Regularly and continuously feed water into the tank through the annular branch pipe, and spray it to the water surface from the inclined downward outlet pipe evenly distributed on the side of the annular branch pipe; the water level in the tank is adjusted by the water level control device, using air stones and nano air pipes Microporous oxygenation of the water body; (3) Regular feeding and touch feeding by flat hanging bait trays, setting the stocking density; (4) Regularly discharge waste water and waste residue, disinfect and adjust the pH value of the water body, Until the cultivation of a batch of tilapia is completed; according to the structural characteristics of the closed cultivation container, the present invention respectively carries out the design of the breeding feed formula, the control of the water body of the box body and the design of the breeding management, so as to realize efficient and high-yield tilapia High-density farming in containers.
Description
technical field [0001] The invention relates to the technical field of aquaculture, in particular to a culture method for tilapia fry based on a closed culture container. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. At present, in order to ensure the survival rate and growth quality of tilapia juveniles, the current artificial breeding method of tilapia is usually based on pond culture, while box culture is rarely used because it is often affected by the influence of the box. The sealed structure, the limitation of the water body environment and the unreasonable breeding method lead to the low breeding density of the fry, the unstable growth environment of the fry, and the disadvantages such as water pollution and disease in the breeding water, and the natural water flow environment and dissolved oxygen of the normal pond cannot be achieved. Therefore, it is still...
