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 the fence. The bottom of the pool is paved with large-grained gravel, and about 50 pairs of frogs can be placed per square meter. Keep the water depth at 10cm and the water temperature at 7-9°C, put it in at 17:00, take out the species of frog the next morning, and leave the egg mass in the circle to hatch naturally. Use 15-20 egg clusters / m 2 Float in water, keep water temperature not exceeding 20°C. Note that the egg mass must be placed in the hatching tank at th...

Abstract

The invention relates to an artificial propagation technology of rana chensinensis david. The artificial propagation technology comprises the following steps of selecting 3-4a wood frogs as frog parents, collecting the frog parents into an egg laying pond of an artificial propagation farm to lay eggs, and performing massive propagation by a natural incubation method; according to the actual conditions, determining the culture density of tadpoles in the propagation pond, feeding plant and animal feeds at fixed time and fixed amount, completely transforming in a transformation pool into young frogs, and then performing forest propagation. By adopting the method, the artificial propagation technology has the advantages that a large amount of young frogs with high resistivity and immunity can be propagated, the yield and benefits of wood frogs are greatly improved, and the development of rana chensinensis david propagation industry is promoted.

Description

technical field [0001] The invention relates to a Chinese wood frog artificial propagation technology, 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 our country is the Chinese forest frog (Rana chensinensis David), which has 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 low s...
