Embodiment 1

[0022] The method for inducing oviposition of spinosa spinosa described in the present embodiment specifically comprises the following steps:

[0023] In April, when the temperature is above 20°C, the parent frogs of spinosa spinosa with a male-to-female ratio of 1:1 are placed in the breeding frog pond for mating and laying eggs, and the stocking density is 2 pairs per square meter. In the frog planting room, and control the indoor light intensity to 2000lux, control the light time from 6:00 am to 18:00 pm, keep the natural light time, and keep the pool water temperature at 19-20°C, dissolved oxygen above 5mg / L, and follow the routine Methods Feeding Rana spinosa, usually at 17:00 pm every day, fed Tenebrio molitor bait once, and the amount of bait fed was 5% of the body weight of the young frogs.

Embodiment 2

[0025] The method for inducing oviposition of spinosa spinosa described in the present embodiment specifically comprises the following steps:

[0026] In April, when the temperature is above 20°C, the parent frogs of spinosa spinosa with a male-to-female ratio of 1:1 are placed in the breeding frog pond for mating and laying eggs, and the stocking density is 1 pair per square meter. In the frog planting room, the indoor light intensity is controlled to be 5000 lux, and the light time is controlled from 6:00 am to 18:00 pm, and the temperature of the pool water is kept at 19-20 ° C, and the dissolved oxygen is more than 5 mg / L. Feeding the spiny frog according to the conventional method, generally feeding the earthworm bait once every day at 18 o'clock in the afternoon, the amount of feeding is 4% of the body weight of the young frog.

Embodiment 3

[0028] The method for inducing oviposition of spinosa spinosa described in the present embodiment specifically comprises the following steps:

[0029] In April, when the temperature is above 20°C, the parent frogs of spinosa spinosa with a male-to-female ratio of 1:1 are placed in the breeding frog pond for mating and laying eggs, and the stocking density is 1 pair per square meter. In the frog planting room, the indoor light intensity is controlled to 3000 lux, the light time is controlled from 6:00 am to 18:00 pm, the natural light time is maintained, and the pool water temperature is kept at 19-20 ° C, and the dissolved oxygen is above 5 mg / L. According to conventional methods, spiny-breasted frogs were fed, and the mixed bait of Tenebrio molitor and earthworm was generally fed once every day at 17 o'clock in the afternoon, and the amount of feeding was 5% of the body weight of the young frogs.

Abstract

The invention provides a giant spiny frog inducing spawning method which comprises the steps that in April, when air temperature is above 20 DEG C, giant spiny frog parents with the female-male ratio of 1 : 1 are placed in a reproduction frog pool for hybridization and spawning, the released density is 1-2 pairs per square meter, the reproduction frog pool is arranged in a reproduction frog chamber, indoor illumination intensity is controlled to be 2000-5000 lux, natural illumination time is kept, pool water temperature is kept at 19-20 DEG C, and dissolved oxygen is at least 5 mg / L. According to the method, the problem that in the prior art, giant spiny frog parent reproduction and spawning cost is high, time and labor are wasted, and frog parents are damaged is solved, the problem that spawning time is interrupted, and large-batch offspring seeds with the same specification cannot be obtained at the same time is solved, the giant spiny frog inducing spawning method can guarantee giant spiny frog parent reproduction spawning size specification orderliness and enable cost to be low, and frog parents are not damaged.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for inducing spawning of spiny frog. 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 first-class ...
