Breeding device for improving metamorphosis rate of frog tadpoles

Abstract

The invention belongs to the technical field of breeding devices, and particularly relates to a breeding device for improving the metamorphosis rate of frog tadpoles. The breeding device comprises a bottom plate and a bracket fixedly connected to the bottom plate; an inclined assembly is further arranged on the outer side of the bracket and used for adjusting the sunlight irradiation angle; the inclined assembly comprises an outer frame, a culture pond and a telescopic piece, and the outer frame is rotationally connected with the bracket; the culture pond is fixedly connected with the outer frame; a hinge ball is further arranged on one side of the outer frame; and the telescopic piece is connected with the hinge ball. By arranging a sealing assembly, semi-sealing of the culture pond is achieved at night and the like when the temperature is low, and it is guaranteed that the internal temperature of the culture pond is not too low while air permeability is guaranteed; according to the breeding device, the inclined assembly and the sealing assembly are combined, so that the device can achieve long-time lighting; and meanwhile, the temperature control is combined, so that the metamorphosis rate of the frog tadpoles is more favorably improved.

Description

technical field [0001] The invention belongs to the technical field of breeding devices, in particular to a breeding device for improving the metamorphosis rate of frog tadpoles. Background technique [0002] Tadpoles are the larvae of frogs and toads. The newly hatched tadpoles have a spindle-shaped body without limbs, mouth and internal gills. They have long flat tails and branched external gills on both sides of the head, which are adsorbed on aquatic plants. , relying on the remaining yolk in the body to provide nutrition, mainly living in groups. When tadpoles mature, they begin to metamorphose, gradually growing limbs, and then (in the case of frogs and toads) gradually degenerate their tails through apoptosis (controlled cell death), gradually becoming frogs or toads. [0003] The metamorphosis period refers to the period when tadpoles turn into young frogs. The main characteristics of tadpoles entering the metamorphosis period are protrusions on the forelimbs on the...

AI Technical Summary

Problems solved by technology

[0004] When the existing breeding device for improving the metamorphosis rate of frog tadpoles is generally fixed and placed during the breeding process of frog tadpoles, the lighting time is limited, which is not conducive to the rapid growth and development of frog tadpoles, and the internal temperature of the breeding device cannot be adjusted. , leading to a lower rate of metamorphosis in frog tadpoles

[0005] It can be seen from the above that the existing breeding devices for increasing the metamorphosis rate of frog tadpoles cannot adjust the lighting angle, which is not conducive to improving the metamorphosis rate of frog tadpoles
