Culture method of tilapia fries based on closed culture container

Abstract

A culture method of tilapia fries based on a closed culture container is disclosed. The culture method adopts a closed culture container. The culture method comprises: (1) configuring a culture feed according to the weight part ratio of formula components of culture feed; (2) periodically and continuously feeding water into the container through an annular branch pipe, and spraying the water to the water surface by inclined downward water outlet pipes which are uniformly distributed on the side of the annular branch pipe; adjusting the water level in the container by a water level control device, and subjecting the water body to micropore aeration by using air stones and nanometer air pipes; (3) timely carrying feeding and touch feeding by a flat hang bait tray and setting the stocking density; (4) regularly discharging waste water and residue, disinfecting water and regulating pH value of water until a batch of tilapia is cultured. According to the structural characteristics of the closed culture container, the invention respectively designs the formula of the culture feed, controls the water body of the container and designs the feeding management so as to realize the high-efficiency and high-yield high-density cultivation of tilapia 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...

Problems solved by technology

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.
