A kind of breeding method of spinosa spinosa

Abstract

The invention provides a kind of cultivation method of spinosa spinosa species frog, comprising the steps of: (1) selecting fast young frogs from the same batch of young frogs cultivated according to conventional methods and cultivating them in a back-up parent frog pond, controlling Select 3-5 young frogs in each young frog pond as the backup parent frogs, and control the stocking density of the backup parent frogs to 20-30 per square meter, and feed the animal live bait regularly once a day, and the amount of bait is 5%-7% of the body weight of young frogs is reserved; (2) until the breeding season, select sexually mature adult frogs over the age of 3 with excellent traits in the reserve parent frog pond and stock them in the species frog pond with a male-to-female ratio of 1:1 Until breeding begins, the stocking density of adult frogs is controlled to be 1-2 male and female adult frogs per square meter, and live animal bait is regularly fed once a day, and the feeding amount is 4%-5% of the body weight of adult frogs. The breeding method of the invention solves the problem of poor or unstable good traits of the frog species in the prior art.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for cultivating Rana spinosa species. Background technique [0002] The spiny-breasted frog, also known as rock chicken, spiny frog, stone scale, stone frog, stone clam, etc., belongs to the amphibian frog family and is mainly distributed in Zhejiang, Anhui, Jiangxi, Hubei, Hunan, Fujian, Guangdong, Guangxi and Hainan Island, etc. The province is a large wild frog unique to our country. Frog spinosa is mild in nature, sweet in taste, and enters the heart, liver, and stomach. Weakness after illness, upset and thirst, etc. also have a certain auxiliary effect. Frog spinosa not only has high medicinal value, but also has high edible value. Its frog meat is rich in various nutrients such as protein, glucose, amino acids, iron, phosphorus and vitamins, and its fat content is very low. The value is much higher than that of bullfrogs. It has always been the f...

Problems solved by technology

However, for the purchase of sexually mature adult frogs from old farmers, not only the aforementioned body fat and poor vitality are prone to occur, but also the blood relationship of the frogs is relatively close, and the quality of the frogs is degraded due to inbreeding. The adult frogs captured in the natural growth area have the above-mentioned thin and weak frogs, carry more parasites, and are prone to unstable good traits of the breeding frogs, resulting in uneven quality of the offspring

The above-mentioned literature does not involve the content of special cultivation and selection of juvenile frogs and species frogs to be used as spinosa species, that is, no attention has been paid to the source, selection and cultivation of spinosa species frogs, ignoring spinosa species The impact of the source, selection and cultivation of the species of frogs on the traits of the species of frogs and the progeny of their progeny cannot be cultivated to the greatest extent through the cultivation of young frogs, the selection and cultivation of species of frogs as spiny-breasted species of frogs. The continuous maintenance of spiny-breasted frogs with excellent traits leads to the selection of spiny-breasted frogs with poor or unstable good traits according to the existing methods, which is very unfavorable for the development of spiny-breasted frog industry
