Ecological breeding method of quasipaa spinosas

Abstract

The invention relates to an ecological breeding method of quasipaa spinosas. The method comprises the steps of strain selection, hybridization, egg laying, hatching, pollywog culturing and young quasipaa spinosa breeding. The ecological breeding method has the advantages that three quasipaa spinosa strains bred by the method have great egg laying amount and fast growing speed; the quasipaa spinosas are fed at the temperature of over 12 DEG C in winter to reduce inner energy consumption in winter and maintain good development of sex glands of the quasipaa spinosas; water current stimulates the quasipaa spinosas to lay eggs, which increases egg laying rate and hatching rate of breeder quasipaa spinosas; and according to the method, quasipaa spinosa breeding ponds can prevent escape, diseases and natural enemies and are propitious to increase survive rate, thereby realizing pollution-free ecological breeding of the quasipaa spinosas. The ecological breeding method of the quasipaa spinosas is provided with breeding ponds for drip egg-laying breeding and winter food supplementing and simulates ecological environment.

Description

technical field [0001] The invention belongs to the breeding and breeding technology of spiny-breasted frog, in particular to artificial breeding and ecological breeding technology of spiny-breasted frog. Background technique [0002] The research on the ecological behavior and artificial breeding technology of Rana spinosa began in the 1980s, and some preliminary discussions have been made on this, and certain results have been achieved. However, no breakthrough has been made in the key technology of breeding, and the egg production, hatching rate, metamorphosis rate, and survival rate are all relatively low. The main shortcoming of the prior art: 1, the breeding parent is not a good breed: catch the wild frog and use it as the breeding parent after a period of raising, or the wild frog breeding offspring is directly used as the parent without artificial selection. 2. Poor management and spawning environment during the winter dormancy period: no feeding during hibernation,...

AI Technical Summary

Problems solved by technology

The main disadvantages of the prior art: 1. The breeding parent is not a good breed: catch wild frogs and raise them after a period of time to make breeding parents, or wild frog breeding offspring are directly used as parents without artificial selection

2. Poor management and spawning environment during the winter dormancy period: no feeding during hibernation, free spawning, less spawning times, and less spawning

3. The design of the frog pond is unscientific: there is no uniform specification, and there is no slope in the pond

4. Low breeding and breeding performance rate: annual spawning times and annual spawning number are 2-3 times / 400-500 grains, egg hatching rate is 85%, tadpole metamorphosis rate is 95%, and young frog survival rate is 95%
