Device and method for automatically collecting fish-egg

Abstract

The invention relates to a device used for collecting roes automatically and a method thereof; the existing method for collecting the roes is operated by manpower with time-wasting and labor-wasting and the roes are easy to be damaged for a long time a plurality of times of collision and friction with the container wall, such as buckets, thus having influence on hatchability. The technical proposal of the invention is that the device used for collecting roes automatically, which is designed by using the principle of the process that water and the roes flow simultaneously in the production process of fry and the water head and consists of a spawning pond, a roe-collecting pond and a hatching pond, leads the roes to be collected automatically in the roe-collecting pond, is filtered by a water strainer and then flows to a hatching bucket by a roe-collecting pipe, and the whole process is completed in the process that the water and the roes flow simultaneously. The device used for collecting roes automatically and the method has the advantages of reducing the labor intensity, improving the working efficiency; reducing the damage of the roes, improving the hatchability; having simple structure, reducing the occupy area, improving the environment and obtaining more ideal positive effects that the labor is saved, the quality is improved, the cost is reduced and the effect is obvious after the practical application of the fish havens.

Description

[0001] Technology leadership [0002] The invention relates to a fish breeding technology in aquaculture, in particular to a fry breeding method and device. Background technique [0003] For a long time, in terms of fry breeding methods and facilities, the majority of fry production units have basically maintained at the level of the 1970s and 1980s, and there has been no major innovation, especially the four major carps in my country: green carp, grass carp, silver carp and bighead carp. Artificial breeding has a history of 50 years, and has made great breakthroughs in technology and production. Parent fish are injected with aphrodisiacs and placed in spawning ponds for spawning. After the eggs are produced, they flow out to the filter water through pipelines. When the net enters the egg collection box, a large number of effective fish eggs can be collected, and the output of fish eggs has increased, but a large number of manual operations are still used in the collection of fi...

[0003] For a long time, in terms of fry breeding methods and facilities, the majority of fry production units have basically maintained at the level of the 1970s and 1980s, and there has been no major innovation, especially the four major carps in my country: green carp, grass carp, silver carp and bighead carp. Artificial breeding has a history of 50 years, and has made great breakthroughs in technology and production. Parent fish are injected with aphrodisiacs and placed in spawning ponds for spawning. After the eggs are produced, they flow out to the filter water through pipelines. When the net enters the egg collection box, a large number of effective fish eggs can be collected, and the output of fish eggs has increased, but a large number of manual operations are still used in the collection of fish eggs. During the production process, workers continue to use buckets to remove fish eggs from the egg collection Take it out of the box, and then pour it into the hatching bucket or ring pond to hatch the fry

Such an old way not only needs more manpower, but also labor intensity is large, time-consuming and laborious. Moreover, fish roe wrapped by transparent cell membranes like blisters are repeatedly bumped and crushed by the walls of containers such as net cages and buckets. friction, easily damaged

The old method is no longer suitable for the development of fishery production
