Novel running water aquaculture system for sturgeon

Abstract

The invention provides a novel running water aquaculture system for sturgeon. The system comprises a water source water flowing channel, a culture pond and a drainage channel, wherein the water sourcewater flowing channel is located above the culture pond; the drainage channel is located below the culture pond. The system is simple in design and high in operability, by means of running water aquaculture, no electric energy is consumed, the aquaculture cost can be greatly reduced, and the problems of complicated structure and higher cost of the conventional sturgeon aquaculture system are solved. By means of the double-layer structure at the bottom of the pond, fish can be effectively separated from harmful impurities such as excrement, residual feed and the like, and the risk that the fish is infected with harmful bacteria is reduced; meanwhile, a large amount of fish is gathered at drainage holes due to huge water pressure produced at the drainage holes in the water exchange processin the culture pond, a plastic mesh plate is mounted above the drainage holes and can prevent fish schools from gathering due to uneven water pressure, mutual extrusion and stress of the fish are reduced, and the problem of yield reduction because of onset of illness and death of the sturgeon which are easily caused by an imperfect sturgeon breeding system conventionally is solved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and more specifically relates to a novel sturgeon flowing water aquaculture system. Background technique [0002] Sturgeon is one of the earliest vertebrates in existence. It is also known as Kubazi and Huso, belonging to the bony fish class, ray fin subclass, sturgeon shape order, and sturgeon family. It has extremely high edible, medicinal, ornamental and economic values. , Sturgeon is a cold-water fish with an optimum growth temperature of 15-22°C. Therefore, natural flowing water aquaculture is currently the most widely used method of sturgeon aquaculture, especially in Guizhou and other places, where there are many reservoirs and mountain spring water resources are abundant. [0003] For example, in the patent with the application number: CN201821643069.6, a new type of temperature-controlled and energy-saving sturgeon breeding system is disclosed. After the clean water flows into the b...
