Problems solved by technology

However, the design of artificial reefs for the endangered light-avoiding fishes in the Yangtze River has not been reported. Therefore, it is urgent to research and develop an artificial reef with simple structure, easy operation and low cost, which can effectively reduce the risk of endangered light-avoiding fishes. The stress response to light at the initial stage of domestication, through the application of this invented device, it is expected to improve the survival rate of endangered light-avoiding fish domesticated in the Yangtze River, and lay the foundation for a breakthrough in its artificial reproduction technology

Abstract

The invention provides an artificial fish reef applied to photophobic fish domestication. The artificial fish reef comprises a star-shaped body structure with a star-shaped cross section and an arc-shaped panel body, wherein the arc-shaped panel body is arranged at the outer side of the star-shaped structure, and partially covers the star-shaped structure, and the arc-shaped panel body and the star-shaped structure define one or a plurality of cavities with openings in two ends. The artificial fish reef has the characteristics that the structure is simple, the manufacturing cost is low, the mobility is good, the firmness is high, disguising spaces are many, the disguising performance is good, the water body flowing performance is good, dirt cannot be easily accumulated, and the like; a single-layer or double-layer placing mode can be adopted, a space favorable for fish to hide and avoid is formed, in addition, the operation is simple and convenient, and the artificial fish reef is applicable to various culture modes of fish pond culture, industrial aquaculture and the like, and has wide application prospects.

Description

technical field [0001] The invention belongs to the field of facility fishery, and in particular relates to an artificial fish reef that can be used in various breeding modes such as fish factory farming and pond farming. Background technique [0002] The phototaxis of fish is the behavior habit of fish to produce directional movement in response to light stimulation, which can be divided into positive phototaxis and negative phototaxis, that is, positive phototaxis towards the light source, and negative phototaxis (photophobia) away from the light source. Among the fish in the Yangtze River Basin, many endangered fish belong to the light-shielding fish, such as long thin loach, long-finned gobi, etc. The reasons for their endangerment include river pollution, water conservancy project construction, overfishing, etc. Currently, , the key to protecting these species is to break through their artificial breeding technology, but the premise is to solve the domestication of thes...
