Flowing water circulation fish farming system

Abstract

The invention provides a fish culture system based on circulation of running water, and belongs to the technical field of aquaculture. The fish culture system comprises water tanks and a culture area.The culture area comprises a hatching subarea, a juvenile fish subarea and an adult fish subarea, and each subarea comprises at least one small fish tank. A water inlet of the culture area is connected with a water supply pipe, and the water supply pipe is connected with water inlets at the tops of the small fish tanks through water distribution devices. Each water distribution device comprises astraight water pipe and an embedded water distribution device. Each embedded water distribution device comprises a water inlet pipe, an air guide pipe and a water distribution disc. The upper ends ofthe water inlet pipes are connected with the water supply pipe, and the lower ends of the water inlet pipes are connected with the water distribution discs. The water distribution discs are arrangedat the bottoms of the small fish tanks, and water distribution holes are formed in the side faces of the water distribution discs. The air guide pipes are connected to positions, above the joints of the water distribution discs and the water inlet pipes, of the water inlet pipes. The fish culture system has the advantages that the water consumption can be effectively lowered, and environmental pollution can be reduced; the double effect of water distribution and oxygen supply can be achieved through the special water distribution devices, and the cost is reduced; the system is provided with the three culture subareas, and the survival rate of fishes can be effectively increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a flowing water circulation fish farming system. Background technique [0002] The core part of the circulating water circulation fish farming device is how to circulate and filter the fish farming water, how the circulating water re-enters the fish tank, the drainage method, how to keep the fish tank clean, water temperature and light control, the degree of automation of the breeding device and the production cost Control, etc., is a multidisciplinary system engineering including biology, physics, machinery, and environmental protection. In addition to providing a good growth space for fish, the fish farming system’s water distribution function and recycling sewage discharge function are particularly important. How to design the corresponding fish tank and water distribution design for different growth cycles of fish is also an urgent problem to be solved. [0003] If the w...

Problems solved by technology

[0008] In order to solve the problems of increasing water consumption and serious environmental pollution in the existing fish farming system, and the single water distribution method cannot meet the needs of both water distribution and oxygen supply at the same time, the present invention provides a circulating water circulation fish farming system to realize Separate farming for three different cycles of fish growth and improve the survival rate of farmed fish
