A kind of double-pond circulating culture method for aquaculture

Abstract

The invention relates to a double-pond circulating aquaculture method and belongs to the technical field of aquaculture. The double-pond circulating aquaculture method comprises the steps of pond preparation, setting of the sizes of the ponds, polyculture, removal of dirt at the bottoms of the ponds, and regulation and control circulating. The double-pond circulating aquaculture method solves the problems of a traditional culture method and the prior art on the aspect of culture facilities are solved, a specific double-pond structure is adopted, a culture pond and a regulation and control pond are adopted, three-dimensional periodic blowdown regulation and control of water is conducted, dirt at the bottoms of the ponds is removed, water pumping is conducted on the top, the structure is reasonable and simple, cost is low, implementation is easy, the application range is wide, water resources are regulated continuously, recycling can be achieved, and a pond of fished can be cultured through one pond of water.

Description

technical field [0001] The present invention relates to a kind of aquaculture method, more specifically, the present invention relates to a kind of double pool circulation culture method used for aquaculture, belongs to the technical field of aquaculture. Background technique [0002] The main breeding methods in my country are: freshwater pond farming, freshwater large water surface farming, shallow sea farming, marine tidal flat farming and factory farming. The first four areas account for 92.7% of the total breeding area in my country, and the output accounts for 91.1%. At present, the freshwater aquaculture model has not broken through the aquaculture form left by the ancestors, and has the following defects: [0003] 1. Has been troubled by a series of external factors such as weather, water source, and artificial; [0004] 2. The rent of ponds is getting more and more expensive, the cost of salvage continues to rise, and the cost of breeding is relatively high; [0...

AI Technical Summary

Problems solved by technology

[0015] The present invention aims to solve the problems of traditional farming methods and the complex and unreasonable structure of multi-pond farming facilities in the prior art, which cannot meet the time difference of nutrient consumption and cannot provide the next water body to adjust the water source, which is not conducive to the growth of cultured fish and the growth of beneficial algae For the problems of reproduction, difficult control of sewage and high cost, a double-pond recirculation breeding method for aquaculture is provided, which makes the structure of the breeding facility simple, reduces the cost, and has a more reasonable structure, meeting the requirements of time difference in nutrient consumption. Provide sufficient water body to adjust the water source, which is beneficial to the growth of farmed fish and the reproduction of beneficial algae, and the pollution is easy to control. The whole method is easy to implement and widely used
