Abstract

The invention provides a method for increasing the number of female wood frogs in field bred wood frog population, which comprises the steps of construction of an embryo development tank, a tadpole development tank, a water sun-drying tank and a wastewater reclamation tank, determination and regulation of water environment pH value, salinity, alkalinity, H2CO3 concentration, Ca<2+> / Mg<2+> ratio, Ca<2+> + Mg<2+> total concentration and Na<+> / K<+> ratio, regulation of favorable water temperature, and wastewater reclamation and recycling. By using the method provided by the invention, the proportion of female wood frogs in the wood frog population bred in a field ecological sealed trench is increased to 62.75%, with an increase of 19.56% compared to the proportion of the female wood frogs in natural wood frog population, the annual mean recapture number of wood frogs is increased to 69.98%, and the mean proportion of female wood frogs in annual bred recaptured wood frog population is 65.68%. The method is an important technology in wood frog industrial high-efficiency breeding.

Description

technical field

[0001] The invention belongs to the technical field of wild animal breeding, and relates to a method for increasing the number of females in a field breeding Rana population. technical background

[0002] Chinese forest frog (Rana chensinensis) is an important wild economic frog species in my country, and it is distributed in some northern provinces (regions) mainly in the Changbai Mountains. Long-term over-fishing has led to a sharp decline in wild resources. It has been included in the "China Red Book of Endangered Animals" and is a national second-class wild animal protection. Rana is an economic frog that has both meat, medicine and health care. In recent years, the cultivation of Rana has been carried out in various places. The number and output of the cultured Rana population have increased significantly. The annual output of Jilin Province alone has reached more than 800 million. The output value exceeds 2 billion yuan. Practice has shown that the ec...
