Embodiment Construction

[0013] Such as figure 1 As shown, the artificial incubator of the hardygloss fry of the present invention comprises a circular hatching device 10 and an external glass jar 20, and the circular hatching device 10 is used for fish egg hatching, and the circular hatching device 10 and the external glass jar 20 are both Made of transparent material, the hatching situation of the fish eggs in the circular hatching device 10 can be seen from the outside. The circular hatching device 10 is placed in an external glass jar 20 . The external glass cylinder 20 is provided with a thermal insulation device 21 and a sewage discharge device (not shown in the figure), and the thermal insulation device 21 stabilizes the water temperature in the external glass cylinder 20 between 27°C and 32°C, and the optimum temperature is 29°C , that is, the optimum hatching temperature of fish eggs is 29° C., so that the external glass cylinder 20 forms a water bath heating and heat preservation effect on ...

Abstract

The invention relates to the technical field of artificial fry breeding, in particular to an artificial incubation device for scleropages fry. Compared with the prior art, the artificial incubation device for scleropages fry comprises a circular incubation device and an external glass jar. The circular incubation device is in a circular shape and is of the best structure which simulates the structure in the oral cavity of milter. Two water outlet pipes in the circular incubation device form a certain angle, it is ensured that water flow in the jar form the fixed direction, the external glass jar is adopted for achieving water-bath heating and heat preservation for the circular incubation device, the water level in the circular incubation device is set to be higher than the water level of the external glass jar so that water outside the jar cannot flow backwards, the clean incubation environment is ensured, and fish eggs are taken out of mouths of milter after milter finishes initial-stage incubation (about 15 days) and placed in the circular incubation device to continue to be incubated. By means of the artificial incubation device, milter can be let free from the incubation task, healthy growth of fry is ensured, the fish egg incubation situation can be seen in real time, and it is ensured that incubation is smoothly carried out.

Description

technical field [0001] The invention relates to the technical field of artificial breeding of fish, in particular to an artificial incubator for the fish fry. Background technique [0002] In the natural environment, after the fertilization of the eggs of the hardy tongue fish, the eggs are hatched in the mouth of the male fish, which usually lasts for about 30 days. During this period, the male fish cannot eat and drink. Eating or being spit out will lead to breeding failure, and our staff cannot observe the development of fish eggs during this period. Therefore, above-mentioned situation has greatly limited the hatching success rate of the roe. Contents of the invention [0003] In order to solve the defects and problems existing in the hatching of the fish roe of the scleroglossus in the prior art, an artificial incubator for the fry of the scleroglossus scleroglossus is provided. [0004] The technical scheme that the present invention adopts for solving its technica...
