Quasipaa spinosa efficient breeding method

Abstract

The invention discloses a Quasipaa spinosa efficient breeding method and relates to the technical field of Quasipaa spinosa breeding. The method comprises the steps of selecting breeding frogs and waiting till the time of sexual maturity of the breeding frogs, wherein the ratio of the number of female breeding frogs to the number of male breeding frogs is 2:1; breeding, wherein stone and a layer of straw mat are laid on the bottom of a Quasipaa spinosa breeding pool, water temperature is 18-22 DEG C in the spawning period, oestrous parent frogs croak for courtship on the straw mat, and after the female frogs spawn, the male frogs ejaculate on the spawns quickly; spawn treating, wherein the straw mat and the spawns are transferred into a treating pool together, and the straw mat is beaten with a disinfectant stick to vibrate; incubation, wherein fertilized eggs are fished out gently after 8am, the area of an incubation pool is 4-5 m<2>, the depth of the pool is 80-90cm, the depth of water is 70-80 cm, spawn density is 900-1100 pieces / m<2>, water temperature is 15-30 DEG C, and PH is 6-8. According to the method, control over the Quasipaa spinosa breeding environment is reasonable, the fertilization rate of the spawns subjected spawn treating can reach over 95%, the hatchability of the fertilized eggs is quite high, and the 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 high-efficiency breeding method for 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 ...

Problems solved by technology

In the process of breeding stone frogs in captivity, the breeding of stone frogs has particularly high requirements on environmental cleanliness, oxygen, temperature and other conditions, and stone frogs are different from ordinary frogs in that the eggs produced by stone frogs are larger, and the eggs are similar to There is almost no mucous membrane between the eggs, and the eggs are relatively scattered, so that the sperm and the eggs cannot be fully contacted, resulting in a low fertilization rate of stone frogs in the prior art, intelligence reaching more than 80%, and the hatching of fertilized eggs The rate is also low, resulting in low economic benefits of raising stone frogs
