A kind of three pond circulation culture method for aquaculture

Abstract

The invention relates to a three-pond circulating culture method for aquaculture, belonging to the technical field of aquaculture. The method of the invention comprises the steps of pond setting, pond size setting, polyculture, bottom sewage discharge and regulating cycle. The present invention solves the problems of the traditional breeding method and the breeding facilities in the prior art. It adopts a specific three-pond structure, which is divided into two breeding ponds and a regulating pond. Low, easy to implement, widely used, the utilization rate of the control pond is improved, the land use area is reduced, the water resource is continuously adjusted, and it can be recycled, so that one pond can raise one pond of fish.

Description

technical field [0001] The present invention relates to a kind of aquaculture method, more specifically, the present invention relates to a kind of three pool circulation culture method 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; [0005] 3...

AI Technical Summary

Problems solved by technology

[0016] This aspect aims to solve the problems of traditional breeding methods and the complex and unreasonable structure of multi-pond breeding 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 beneficial algae The problem of breeding, dirt is difficult to control, high cost, and large land use area is provided. A three-pond circulating culture method for aquaculture is provided, which makes the structure of the breeding facility simple, reduces costs, and reduces the land use area. At the same time, the structure is more It is reasonable, meets the requirement of nutrient consumption time difference, provides sufficient water body to regulate water source, is beneficial to the growth of farmed fish and the reproduction of beneficial algae, and the dirt is easy to control. The whole method is easy to implement and widely used
