Viscous fish egg killing device

Abstract

A viscous fish egg killing device. Every two conductive fish nests (1) are distributed side by side at a certain distance. One conductive fish nest (1) of every two conductive fish nests (1) is connected to a positive pole (3) of a power source, and the other conductive fish nest (1) is connected to a negative pole (5) of the power source. Each conductive fish nest (1) is connected in series or in parallel to the power source through a conducting wire (2). The fish nest attracts fish to lay eggs. After the device is electrified, an electric field is formed between two conductive fish nests, so as to kill fertilized eggs in the fish nest, and a method for eliminating invading fish is provided from the perspective of eliminating fertilized eggs of the fish in reverse thinking, and the device has a simple structure, is easy to be operated, and is efficient.

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 occur in the United States and Europe. For example, carps such as carp 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 erad...

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
