Quasipaa spinosa induced spawning and efficient breeding method

Abstract

The invention discloses a Quasipaa spinosa induced spawning and efficient breeding method and relates to the technical field of Quasipaa spinosa culture. The method comprises the steps of breeding frog selection; induced spawning, wherein the mixed solution containing chorionic gonadotropin, luteinizing hormone releasing hormone and normal saline is injected into the abdomen of each breeding frog, the use concentration of chorionic gonadotropin is 240-160 units / ml, the use concentration of luteinizing hormone releasing hormone is 7-9 micrograms / ml, 15-20 ml mixed solution is injected into each male frog, and 7-10 ml mixed solution is injected into each female frog; breeding; spawn treating, wherein a straw mat and spawns are transferred into a treating pool together, and the straw mat is beaten with a disinfectant stick to vibrate; incubation. According to the method, control over the cleanness, oxygen content and temperature of the Quasipaa spinosa breeding environment is reasonable, the fertilization rate of spawns subjected to induced spawning and spawn treating can reach over 95%, the hatchability of fertilized eggs is over 90%, effect time is shortened to 42 hours, spawn incubation time is shortened to 12.5 days, 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 for raising stone frogs, and in the prior art, the method of catalyzing common frogs is used for catalyzing catarrh, and the effect of catalyzing is poor, or even uneven.
