Description

Semi-submersible multi-object artificial fish spawning site

Technical Field

The utility model belongs to the field of artificial spawning sites for river fishes, and particularly relates to a semi-submersible multi-object artificial fish spawning site.

Background

The artificial fish spawning site can provide necessary sites for fish, particularly for spawning and breeding of protected fish, such as artificial laying of gravel materials or planting of aquatic plants at specific positions in a river channel for spawning and landing of the fish. In recent years, with the rapid development of economic society, the demand of water resources is increasing, which also prompts us to build more and more reservoir dams. After the dam of the reservoir is built, the hydrological runoff conditions of the river channel of several kilometers or even dozens of kilometers at the downstream of the dam are fundamentally changed, for example, when the reservoir is flood discharged in flood season, a natural spawning site at the downstream of the dam can be deeply buried at the water bottom or damaged by high-speed water flow; when the reservoir normally operates, the ecological flow discharged by the reservoir is usually much smaller than the natural flow, and the natural spawning site is exposed on the water surface. In both cases, the failure of normal spawning of fishes that produce heavy or viscous fish eggs or the failure of normal hatching of produced fish eggs is seriously affected. Therefore, it is particularly important to add artificial fish spawning sites and danger-avoiding habitat spaces in the riverway with serious artificial interference.

At present, artificial fish spawning sites mainly have two categories, one is to lay sand gravel in large area below the water surface to produce viscous eggs, and the other is to bind palm leaves or other materials on a fixed frame for the viscous eggs to land. The two artificial spawning sites have fixed structural forms and cannot adapt to water level changes, particularly, the sand gravel paving material is buried at the bottom of the water in a deep flood season, and the sand gravel paving material is exposed in the air in a dry season, so that the basic functions of the spawning sites cannot be exerted. Therefore, it is necessary to provide a multi-target artificial fish spawning site in a river course with large water level fluctuation, which can adjust the position of the spawning site by itself according to the water level change, maintain an effective flooding height all the time, and simultaneously allow both the deposition of the sticky eggs and the sticky eggs.

In the spawning season, the parent fish can seek the suitable spawning position, such as the suitable conditions of water temperature, illumination, flow field, nutrient concentration, substrate and the like, and the artificial spawning site is difficult to be arranged at the accurate position at one time, so that the position and the submerging depth of the spawning site are required to be adjusted according to the actual spawning monitoring result, and the optimal spawning effect is sought. Therefore, there is a need for an artificial spawning site that can be adjusted in structure and position as needed.
