Giant spiny frog reproduction frog cultivation method

Abstract

The invention provides a giant spiny frog reproduction frog cultivation method which comprises the steps that 1. froglets with high growing speed are selected from froglets which are cultivated according to a conventional method in the same batch and are cultivated in reserved frog parent pools, 3-5 froglets are selected in each froglet pool are selected to be used as reserved frog parents, the released density of the reserved frog parents is controlled to be 20-30 frogs per square meter, animal live bait is cast for feeding in a timing mode by one time each day, and bait casting amount is 5%-7% of the weight of each froglet, and reserving is carried out; and 2. in a breeding season, sexually-mature grown frogs which has excellent characters and are at least three years old are selected in the reserved frog parent pools are subjected to stocking in a reproduction frog pool according to the female-male ratio of 1 : 1 until breeding is started, grown frog released density is controlled to be 1-2 released female grown frogs and1-2 released male grown frogs per square meter, animal live bait is cast for feeding in a timing mode by one time each day, and bait casting amount is 4%-5% of the weight of each grown frog. According to the cultivation method, the problem that in the prior art, giant spiny frog reproduction frog characters are poor, or excellent characters are not stable is solved.

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
