Abstract: A viscous fish egg killing device is provided. 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.
