Embodiment Construction

[0021] The present invention will be further described below:

[0022] A kind of breeding method of spiny-breasted frog, comprises hatching pond, metamorphosis preparatory pond, metamorphosis pond, juvenile frog pond, adult frog pond, is characterized in that it is carried out according to the following steps:

[0023] In the first step, the tadpoles are hatched, and a hatching pool is set up. The area of ​​the hatching pool is preferably 1㎡-2㎡, the height is 1.0m, and the water depth in the pool is 15cm-20cm. The hatching pool is kept in normal light and avoids strong direct sunlight. The water temperature of the pool is 23°C~28°C, which is suitable for tadpoles to hatch at this water temperature. The dissolved oxygen is greater than or equal to 5mg / L, and the pH value is 6.5~7.5, which is suitable for the survival of tadpoles. Feed eggs once a day;

[0024] The second step is to prepare tadpoles for metamorphosis. Set up a metamorphosis preparation pool. When the tadpoles ar...

Abstract

The invention discloses a giant spiny frog culture method, and aims to solve the problems of low metamorphosis rate and low survival rate of giant spiny frogs. The method comprises the stages of tadpole incubation, tadpole metamorphosis preparation, tadpole metamorphosis, froglet culture, adult frog feeding and the like. According to the method disclosed by the invention, the giant spiny frogs are cultured at different degrees according to different growth stages, particularly nutrient enrichment is performed during tadpole metamorphosis, enough nutrition needed by metamorphosis is provided for the tadpoles, and the metamorphosis and survival rate of the tadpoles can be improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating Rana spinosa. Background technique [0002] Spinosaurus frog, commonly known as stone frog, spiny frog, rock chicken, etc., belongs to Amphibians, Anura, Ranaidae, and Rana. It is a unique large-scale edible frog distributed in the hilly and mountainous areas of southern my country.
