Embodiment 1

[0016] A method for breeding fish fry, comprising the following steps:

[0017] (1) 3-5 days before the fish fry are put in a suitable place to breed, splash the water surface with the activated bacteria liquid, and sterilize the factory building by ultraviolet light irradiation;

[0018] (2) Divide the cultivation pool into 16 activity pools with buoys, and put the hatched larvae into the activity pool in the cultivation pool in the factory building. The larvae put into the cultivation pool need to be inspected regularly by special personnel and fed with mixed feed once After each feeding, turn on the water spray pipe to spray water and increase oxygen in each activity pool, so that the dissolved oxygen in the water is 7-9mg / L;

[0019] (3) After the yolk sac of the fish fry disappears, start feeding the egg yolk again. The method is to wrap the egg yolk with 1-2 layers of gauze, crush it, and then pat it on the water surface, and move it while patting to make the egg yolk ev...

Abstract

The invention provides a fry breeding method and belongs to the field of aquaculture. According to the fry breeding method, before breeding, an excitation bacterium solution is sprayed to a pool and can kill or restrain pathogenic microorganisms and harmful matter; then movable pools are erected on the breeding pools, the inner breeding environments of all the movable pools are not affected one another; after fries grow up, the fries are gathered in one breeding pool, and a good breeding environment is provided for the fries; every time feeding is completed, spray pipes are opened to spray water and increase oxygen to the movable pools, the dissolved oxygen in water is increased, excitation and growth of normal floras and beneficial algae in a breeding ecological system are promoted, and the ecological balance of aquatic water is maintained. By means of the fry breeding method, the breeding ecological environment is adjusted, and the fry survival rate is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a fry breeding method. Background technique [0002] With the gradual expansion of the scale of fish farming, many problems that have not been encountered before are gradually revealed. Many farmers use fish feed with high protein content, which is likely to cause fatty liver disease and reduce the survival rate and growth rate of fish. Inadvertently paying attention to changes in the water body, resulting in a large number of fish deaths and other phenomena also often occur. Contents of the invention [0003] The problem to be solved by the present invention is to provide a fry breeding method, which adjusts the breeding ecological environment of the fry and greatly improves the survival rate of the fry. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A method fo...
