Description

Corridor type breeding system

Technical Field

The invention belongs to the technical field of aquaculture, and particularly relates to a corridor type aquaculture system.

Background

Pond type culture is a culture mode of fresh water areas in most areas of China, the water quality of a pond directly influences the survival and growth speed of fishes or shrimps, if the fish pond is not frequently filtered and discharged, the water quality is easily deteriorated, and the water in the pond is also easily deteriorated into a smelly water pond. In the traditional circulating water system for indoor cultivation, the depth of a cultivation pond is usually 1-2 meters, and the cultivation sewage is generally filtered by a micro-filter or a fixed sieve to remove solid suspended matters. However, the simple fixed sieve filtering treatment effect is not ideal as the culture pond is fed with excessive feed, excrement is accumulated, suspended matters are excessive and the like.

Chinese patent application No. CN201721890207.6 discloses a modular fish-farming runway and pond circulating water aquaculture system. This runway of breeding fish includes: the runway comprises a runway bottom and a runway side wall; the bottom of the runway is formed by splicing stainless steel plates, and the side wall of the runway is formed by splicing the stainless steel plates; a water inlet provided with a water pushing and oxygen increasing device; the water inlet is arranged at one end of the runway; a water outlet provided with a sewage collecting device; the water outlet is arranged at the other end of the runway; a water inlet screen is arranged in front of the runway and the water inlet, and a water outlet screen is arranged between the runway and the water outlet.
