High-efficiency water-changing fry breeding pool

Abstract

The invention discloses a high-efficiency water-changing fry breeding pool comprising a breeding pool body, partitions, a moving plate, filter plates, an isolation screen plate, a frame, a lifting device and a moving part. The high-efficiency water-changing fry breeding pool is characterized in that two sets of the partitions are disposed in the middle of the breeding pool body; the breeding poolbody is divided into two parts of a first breeding barn and a second breeding barn; a through hole allowing fries to pass through is opened in the middle of the partition; the moving plate is connected with the lifting device which is disposed on the frame; the frame is arranged above the breeding pool body; two sets of the partitions are respectively arranged on the lower portions of the first breeding barn and the second breeding barn; the end portion of the isolation screen plate is located below the through hole; a first filter plate is located inside the first breeding barn while a secondfilter plate is positioned inside the second breeding barn; a moving part is slidably arranged on the frame. The high-efficiency water-changing fry breeding pool has the advantages of facilitating water changing in the first breeding and second breeding barns, achieving the best breeding environment inside the first breeding and the second breeding barns, and being conducive to healthy growth ofthe fries.

Description

technical field [0001] The invention relates to the technical field of fry cultivation, in particular to a fry cultivation pond with high-efficiency water exchange. Background technique [0002] Aquaculture is a high-efficiency production model that uses industrial methods for fish farming. It uses water circulation technology and aeration technology to efficiently breed fish. [0003] At present, in the process of fry breeding, the metabolites of fry are directly discharged into the breeding pond to form sediments. The operator often cleans the sediment inside the breeding pond regularly. However, the breeding pond still contains certain toxins, which are not conducive to The substance used for fry growth, when the culture pond is in a state for a long time, the internal toxins will increase, which will have bad side effects on the healthy growth of fry, so it is necessary to completely replace the water body inside the culture pond. [0004] Generally, the process of chan...

[0003] At present, in the process of fry breeding, the metabolites of fry are directly discharged into the breeding pond to form sediments. The operator often cleans the sediment inside the breeding pond regularly. However, the breeding pond still contains certain toxins, which are not conducive to The substance used for fry growth, when the breeding pond is in a state for a long time, its internal toxins will increase, which will have adverse side effects on the healthy growth of fry, so it is necessary to completely replace the water body inside the breeding pond

[0004] Generally, the process of changing water in aquaculture ponds is to discharge part of the water inside the aquaculture ponds first, and then inject clean water into the aquaculture ponds. This way of changing water makes the aquaculture ponds continue to contain a large amount of toxins and other substances; When changing water in the pool, the process of drainage and water intake is carried out at the same time to achieve water change. This water change method is inefficient, wastes resources, and takes a long time to change water; none of the above water change methods can clean the aquaculture pond.
