Push flow type runway culture method and culture system used by push flow type runway culture method

Abstract

The invention discloses a push flow type runway culture system. The push flow type runway culture system comprises a water pushing device, a dirt collection device and a culture groove group which arearranged in a pond, wherein the culture groove group comprises at least two parallel culture grooves; a walking path is arranged between the adjacent culture grooves; the water pushing device is arranged at one side of the front ends of the culture grooves; the dirt collection device is arranged at one side of the tail ends of the culture grooves; an oxygenation device is arranged in each culturegroove; each culture groove is internally provided with a culture groove oxygen detection device and an outer pond oxygen detection device is arranged in the pond located at the outer parts of the culture grooves and the dirt collection device. The invention also provides a push flow type runway culture method utilizing the culture system. The push flow type runway culture system disclosed by theinvention has the technical advantages of energy saving and high efficiency.

Description

technical field [0001] The invention relates to the field of fish breeding, in particular to a push-flow track breeding method and a used breeding system. Background technique [0002] Flowing water fish farming is a method of high-density intensive fish farming in a fish pond with water exchange. Generally, reservoirs, lakes, rivers, mountain streams, springs, etc. are used to continuously flow through the fish pond with the help of water level differences, drainage or interception facilities, and water pumps, or to purify the discharged water and then inject it into the fish pond. Since the water flow plays the role of inputting dissolved oxygen and removing fish excrement, the pool water can maintain good water quality, which creates conditions for high-density intensive breeding of fish. [0003] At present, the "sink type" aquaculture tanks used in ponds in Jiangsu, Zhejiang, Shanghai and Anhui are generally made of glass fiber reinforced plastics and concrete. FRP ma...

AI Technical Summary

Problems solved by technology

FRP material itself is a very good construction material, but when it is used in aquaculture tanks, due to the insufficient geological hardness of the pond, it may cause deformation or even breakage of the material, and the construction cost is relatively high; This method has a large amount of local land hardening, which will cause local damage to the cultivation layer of the pond, and often causes disagreements from the land management department.

[0004] At present, the method of aeration and pushing water is mostly used in the aspect of aeration and water pushing. The larger the aeration volume, the faster the flow velocity of the flow, but this kind of pushing flow method often consumes a lot of energy; in the breeding process, the flow rate and oxygen increase are two factors. There is not always a direct proportional relationship between the needs in terms of flow and aeration. The way of aeration and pushing flow does not match well with the needs of breeding in terms of pushing flow and oxygenation.
