Quasipaa spinosa breeding method

Abstract

The invention provides a Quasipaa spinosa breeding method and relates to the field of Quasipaa spinosa breeding techniques. The method is characterized by including the following steps that breeding Quasipaa spinosa is selected, wherein sexual maturity is required, the weight is required to range from 250g to 400g, and the female-male ratio is 2:1; breeding is conducted, wherein stone is laid at the bottom of a pond for breeding the Quasipaa spinosa, the water temperature is controlled between 18 DEG C and 22 DEG C in the egg laying period, sexually mature parent Quasipaa spinosa stands on the stone in the breeding season and croaks for courtship, male Quasipaa spinosa bends over the back of female Quasipaa spinosa, and the male Quasipaa spinosa rapidly ejaculates on eggs after the female Quasipaa spinosa lays the eggs; hatching is carried out, wherein the area of the hatching pond is generally 4-5 m<2>, the depth of the pond is 80-90 cm, the temperature is controlled between 20 DEG C and 26 DEG C, the water level is controlled between 70 cm and 80 cm, the egg laying density is 900-1100 particles per square meter, it is guaranteed that running water is injected, water is changed once every day, and tadpoles can be hatched in 2-3 days. The cleanliness, oxygen and temperature of the breeding environment of the Quasipaa spinosa are controlled reasonably, the egg laying fertilization rate of the Quasipaa spinosa is high, the hatchability of fertilized eggs is high, and economic benefits of Quasipaa spinosa breeding are increased.

Description

technical field [0001] The invention relates to the technical field of stone frog breeding, in particular to a method for breeding stone frogs. Background technique [0002] Bamboo stone frog (Quasipaa spinosa) standard name is spinosa, also known as stone clam, rock pheasant, pheasant, stone jelly, flying fish, stone scales, stone toad, stone shrimp, stone pit frog, stone chaos, wooden pagoda tree (South Sichuan) etc., is a kind of animal of amphibian anura order frog family. The stone frog tadpole has a strip-shaped body, a thick tail, dark yellow skin, and small black stars. On the back of the joint between the body and the tail, there is a black "V" pattern. The ability is very strong, and the stone frog is big and strong. Adult frogs generally have a body length of 10-13 cm and a weight of more than 150-250 grams. The large ones can reach more than 500 grams. The skin of the stone frog is rough, the skin on the back is dark gray, and there is a lot of oil on it. The h...

Problems solved by technology

In the process of raising stone frogs artificially, the breeding of stone frogs has particularly high requirements on the cleanliness of the environment, oxygen, temperature and other conditions. In the prior art, the fertilization rate of eggs laid by stone frogs is low, and the hatching rate of fertilized eggs is also low. The economic benefits of raising stone frogs are not high
