Problems solved by technology

However, in recent years, with more and more frequent warm winters, spiny-breasted frogs will temporarily become active during the wintering period, causing the spiny-breasted frogs to lose weight and even die. Therefore, the overwintering management of spiny-breasted frogs raised higher demands

Embodiment 1

[0019] The method for surviving the winter of spinosa spinosa described in the present embodiment, specifically comprises the following steps:

[0020] In winter, when the water temperature dropped below 10°C, the spiny frogs to be overwintered in the same batch were placed in the overwintering pool, and the stocking density of the spiny frogs was controlled to be 50 / m 2 , the water in the wintering pool is constant flow water, and the flow velocity of the control water is 2m 3 / hour, the pool water temperature is below 10°C, the pool water depth is controlled to be 15cm, and the dissolved oxygen is above 5mg / L.

Embodiment 2

[0022] The method for surviving the winter of spinosa spinosa described in the present embodiment, specifically comprises the following steps:

[0023] In winter, when the water temperature dropped below 10°C, the same batch of spiny-breasted frogs to be overwintered were placed in the overwintering pool, and the stocking density of the spiny-breasted frogs was controlled to be 100 / m 2 , the water in the wintering pool is constant flow water, and the flow velocity of the control water is 0.5m 3 / hour, the pool water temperature is below 10°C, the pool water depth is controlled to be 25cm, and the dissolved oxygen is above 5mg / L.

Embodiment 3

[0025] The method for surviving the winter of spinosa spinosa described in the present embodiment, specifically comprises the following steps:

[0026] Enter winter, when water temperature drops below 10 ℃, the spiny-breasted frog that waits for overwintering of the same batch is placed in the overwintering pond, and described spiny-breasted frog stocking density is controlled to be 75 / m 2 , the water in the wintering pool is constant flow water, and the flow rate of the control water is 1m 3 / hour, the pool water temperature is below 10°C, the pool water depth is controlled to be 20cm, and the dissolved oxygen is above 5mg / L.

Abstract

The invention provides an overwintering method for giant spiny frogs. When the water temperature falls below 10 DEG C in winter, giant spiny frogs waiting to overwinter of the same batch are placed into an overwintering pond, and the stocking density of the giant spiny frogs is controlled at 50-100 frogs per m<2>; water in the overwintering pond is constant flow water of which the flow speed is 0.5-2 m<3> per hour; the temperature of the water in the pond is below 10 DEG C; the water depth in the pond is controlled at 15-25 centimeters, and the dissolved oxygen is controlled over 5mg / L. By adopting the method, the technical problems of great reduction in the body weight and even death of overwintering giant spiny frogs due to transient activity of the giant spiny frogs under the influence of climate during overwintering are solved.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for overwintering spiny-breasted frogs. 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-cla...
