Embodiment Construction

[0029] It takes 1500m to cast 1000 pairs of species of frogs 2 Breeding grounds, in which the water surface of egg-laying hatching ponds and rearing ponds is about 1000m 2 , Pond ridge, irrigation canal, drainage canal, etc. occupy 500m 2 To ensure the water demand of the breeding ground, there should be 0.05-0.1m 3 / s flow rate, the water source is free from pollution. After the breeding ground is sterilized, use iron mesh or plastic film to surround the pool with a height of 80cm and an area of ​​20-30cm. 2 fence. The bottom of the pool is paved with large-grained gravel, and about 50 pairs of species of frogs can be placed per square meter. Keep the water depth at 10cm and the water temperature at 7-9°C, put them in at 17:00, take out the frogs the next morning, and leave the egg clusters in the circle to hatch naturally. Use 15-20 egg clusters / m 2 Float in water, keep water temperature not exceeding 20 ℃. Note that the egg mass must be placed in the hatching tank at...

Abstract

The invention relates to a method for large-scale cultivation of Chinese forest frogs, comprising the following contents: selecting 3-4a raw forest frogs as seed frogs, collecting the seed frogs to lay eggs in artificial breeding ground spawning pools, and carrying out a large number of species by natural hatching method Breeding: Determine the stocking density of tadpoles in the breeding pond according to the actual situation, regularly and quantitatively feed vegetable and animal feed, and enter the forest to breed after the metamorphosis pond completely metamorphoses into young frogs. Through this method, a large number of young frogs with high resistance and immunity can be cultivated, the yield and benefit of the forest frog can be effectively improved, and the development of the breeding industry of the forest frog in China can be promoted.

Description

technical field [0001] The invention relates to a method for large-scale cultivation of Chinese wood frogs, in particular to a technology capable of rapidly breeding a large number of young frogs with resistance and immunity. Background technique [0002] The most precious species of frogs in my country is the Chinese forest frog (Rana chensinensis David), which has a high economic value and has led to mass hunting of its wild species. Due to the long-term unrestrained capture and the destruction of the ecological environment in the producing areas, the wild resources of Rana in China are decreasing day by day. In order to meet people's needs and protect the increasingly depleted wild resources, my country has gradually begun to conduct semi-artificial breeding experiments on Chinese forest frogs, and has achieved certain achievements. With the development of China's forest frog breeding industry, semi-artificial breeding of Chinese forest frogs has exposed problems such as...
