A water-replenishing fishway with an adaptively-adjusted floating dock is provided. The water-replenishing fishway comprises a fishway body, wherein the bottom of the fishway body is rotationally connected with a floating dock structure, an auxiliary swimming structure is arranged inside the fishway body, and an adjusting structure used to adjust the auxiliary swimming board of the auxiliary swimming structure is arranged on said floating dock structure. The fishway body is excavated with a sliding groove fitting with the sliding block, a first spring is arranged between the sides of the sliding groove and the sliding block, and the bottom of the sliding block is articulated with a roller, which is in contact with the surface of the moving plate of the adjusting structure.

The present disclosure discloses a buffering fishway suitable for emergent flood discharge with reduction in damage and a buffering method thereof. The buffering fishway includes a fishway body, wherein a migration passage is arranged inside the fishway body, one end of which is rotationally connected with a fixing base, and the other end of which is rotationally connected with a counterweighting floating dock, and a plurality of buffering plates capable of swinging are hinged inside the migration passage, furthermore, the present disclosure also provides a buffering method corresponding to it. The present disclosure effectively reduces the potential energy of the flood and weakens the impact force on the fish. Therefore, the gate dam having this design effectively avoids the fish in the fishway from being fiercely impacted by the flood and easily resulting in damage during discharging flood, having a high protective effect on the fish.

A viscous fish egg killing device is provided. Every two conductive fish nests () are distributed side by side at a certain distance. One conductive fish nest () of every two conductive fish nests () is connected to a positive pole () of a power source, and the other conductive fish nest () is connected to a negative pole () of the power source. Each conductive fish nest () is connected in series or in parallel to the power source through a conducting wire (). 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.
