Fry rearing device for large-scale family rearing

Abstract

The invention discloses a fry rearing device for large-scale family rearing, and belongs to the technical field of aquiculture equipment. The fry rearing device for large-scale family rearing comprises a thermal insulation water tank and a hatching rearing barrel which is arranged in the thermal insulation water tank, wherein a water level control drainage pipe is arranged in the thermal insulation water tank and is vertically inserted into the bottom of the thermal insulation water tank; the upper end of the water level control drainage pipe is lower than the height of the thermal insulationwater tank; the hatching rearing barrel consists of a barrel body and a pipe fitting which is arranged on the barrel; and the pipe fitting comprises an overflow pipe, an upper pumping pipe, a lower pumping pipe, an upper drainage pipe, a lower drainage pipe, a suction drum, a valve a, a valve b, an elbow a, an elbow b and a three-way pipe. By using the fry rearing device for fry rearing, the riskof cross infection is avoided in a water changing process, the drop speed of water temperature in the batching rearing barrel is slowed, the electric energy consumed for heating the fry rearing wateris reduced, and meanwhile, the fry rearing device is easy and convenient to operate, quick and labor-saving.

Description

Technical field: [0001] The invention belongs to the field of aquaculture equipment, and in particular relates to a seedling raising device for large-scale family cultivation. Background technique: [0002] In the process of fish and shrimp breeding, it is necessary to build families on a large scale. In order to avoid confusion among families, the fertilized eggs of each family should be hatched and cultivated separately. At present, the containers for family cultivation generally have plastic buckets or plastic pots. During the hatching and cultivation process, it is necessary to change the water frequently or to hatch with long running water. The water changing device is generally a water suction hose, one end of which is connected to a water filter drum, and the hatching and breeding families are changed in turn. After disinfecting and cleaning the water device, change the water for another family. During the operation, because the water changing device is used repeatedl...
