Cultivating method with variable-flow circulated water

Abstract

The invention relates to a cultivating method with variable-flow circulated water. The flow velocity of the circulated cultivating water in a cultivating pond is regulated in an interval way by adjusting the flow of a water pump in the interval way. The cultivating method has the advantages that water in the cultivating pond is better purified to increase cultivating capacity; the stimulation of water on cultivated fish is enhanced to stimulate movement strength and ingestion strength of the cultivated fish so as to improve the quality of the fish; the operation efficiency of a water treatmentdevice can be improved, so that the whole power consumption of the water treatment device is reduced; and the overall investment intensity of the water treatment device can be reduced.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to the field of artificial circulating aquaculture. Background technique [0002] The artificial circulating aquaculture of the prior art is to use pipelines and water pumps to connect the breeding pond and the water treatment device to form a circulation system. The water pump continuously pumps the water in the breeding pond into the water treatment device with a certain flow rate. , the water returns to the breeding pond. The water in the cultivation pond of the cultivation method of the prior art flows at a constant speed. The deficiency of the breeding method of prior art is: [0003] 1. Since the water in the aquaculture pond flows at a constant speed, when the flow rate is low, the particulate pollutants deposited on the bottom of the aquaculture pond are not easy to be pumped into the water treatment device with the water flow, but will stagnate at the bottom of the aquaculture ...

AI Technical Summary

Problems solved by technology

[0003] 1. Since the water in the aquaculture pond flows at a constant speed, when the flow rate is low, the particulate pollutants deposited on the bottom of the aquaculture pond are not easy to be pumped into the water treatment device with the water flow, but will stagnate at the bottom of the aquaculture pond for a long time. The water in the breeding pond cannot be thoroughly cleaned

[0004] 2. Aquatic products, such as fish, grown in aquaculture ponds grow in water with a constant flow rate. Because they are not stimulated by changes in the water body, their exercise intensity is weak and their feeding intensity is also weak, resulting in poorer flesh quality than wild fish.
