Embodiment Construction

[0014] The method for cultivating giant salamanders in a simulated ecological environment of the present invention can be divided into six stages of artificially induced spawning, artificial fertilization, incubation of salamander eggs in a simulated ecological environment, and feeding of immature salamanders, juvenile salamanders and adult salamanders in a simulated ecological environment, and its implementation steps are as follows:

[0015] (1) Artificial induced labor of giant salamander:

[0016] a) Select mature broodstock: the abdomen is swollen, and the rear abdomen is lightly touched with hands. The female salamander with plump, soft and elastic feeling can be used as the female broodstock; the male salamander with prominent muscles around the cloaca and obvious redness and swelling can be used as the male broodstock ;

[0017] b) Sex hormone oxytocin drugs: After the mature parent salamanders are selected, the drugs are prepared according to the body weight of the gi...

Abstract

The present invention relates to giant salamander aquiculture method and apparatus in simulated habitat. Giant salamander is hatched and cultured in a simulated habitat with proper natural geographic condition, overshadowed and water flowing environment established according to the characteristics of giant salamander in different growth stages, including oviposition, hatching, infant giant salamander, adult giant salamander, etc. During oviposition and hatching, spawning inducing medicine and hatching liquid in proper amount are adopted separately. The present invention is favorable to raising the propagation rate of giant salamander and promoting the growth of giant salamander.

Description

technical field [0001] The invention belongs to the technical field of aquatic animal breeding, in particular to an artificial hatching method and device for giant salamanders. Background technique [0002] The giant salamander, commonly known as the giant salamander, is an amphibian that originated in the joint ancient land period more than 350 million years ago. With the drift of the ancient land, the change of geography and climate, natural selection and evolution, especially the recent change of the ecological environment, the living conditions have been destroyed, and the giant salamander is facing the situation of extinction. Therefore, accelerating the development of artificial breeding and saving giant salamander species is highly valued by the state and society. The key link in the breeding of giant salamanders is to increase the reproductive rate, and the key to increasing the reproductive rate is fertilization and hatching. Giant salamander reproduction is chara...
