Viscous fish egg killing device

Abstract

The invention relates to a viscous fish egg killing device. Every two conductive egg collectors are distributed at a certain interval, one of every two conductive egg collectors is connected with the positive pole of a power supply, the other one of every two conductive egg collectors is connected with the negative pole of the power supply, and each conductive egg collector is connected with the power supply in series or parallel by virtue of a wire. The viscous fish egg killing device provided by the invention adopts multiple conductive egg collectors, every two conductive egg collectors arerespectively connected with the positive pole and negative pole of the power supply, the characteristic that the egg collector can attract fish to lay eggs is utilized, after the conductive egg collectors are electrified, an electric field is formed between the two conductive egg collectors, fertilized eggs in the egg collector can be killed, a method for eliminating the fish which invades is provided in the aspect of eliminating the fertilized eggs of the fish in negative thinking, and the viscous fish egg killing device disclosed by the invention is simple in structure, easy in operation and high in efficiency.

Description

technical field [0001] The invention belongs to the field of biotechnology, in particular to a device for killing sticky fish eggs. Background technique [0002] Today, with the increasingly frequent exchanges between countries and regions, invasive organisms have caused certain pressures on the survival of indigenous species, and brought certain negative ecological impacts in some areas. Among them, some fish are classified as invasive species in certain areas and are regarded as species that should be eliminated. The most typical examples occurred in the United States and Europe. For example, carps such as carps have caused major ecological problems, resulting in the decline of some species populations, and even endangering some rare species. Carp are designated as invasive by legislation in several US states, allowing various methods to eradicate existing individuals while avoiding water-to-water spread. Existing individuals of invasive fish are difficult to completely ...

AI Technical Summary

Problems solved by technology

However, each method has certain limitations, such as high labor intensity and low efficiency, and various methods that help to remove invasive fish need further research

[0003] At present, the commonly used method of removing invasive fish is mainly for adult fish and juvenile fish, and there are few reports on removing invasive fish from the perspective of fertilized eggs
