Problems solved by technology

However, no breeding method has been found for the seedlings of silvery whitefish in Dianchi Lake, and the breeding methods of other whitefishes are less effective in artificial reproduction of silvery whitefish. An artificial breeding method suitable for silvery whitefish is urgently needed to promote the recovery and expansion of silvery whitefish populations.

Embodiment 1

[0012] Example 1: On March 9, 2017, 6 sexually mature silver white fish females and 7 male fish were collected from the spawning ground of Dianchi silver white fish. After inspection, all the male fish can successfully squeeze out semen, and some female fish can successfully squeeze out semen. Eggs were produced, followed by artificial insemination and hatching. The hatched fish fry were artificially cultivated and domesticated in small pools and ponds. From late February to early March 2019, silver and white fish with well-developed selective glands were artificially propagated at a ratio of 1:1 between male and female.

[0013] Artificial induced labor: female fish are given 2 injections, the first injection dose is 3 mg / kg fish body of dioconone maleate (DOM), 200 iu / kg fish body of chorionic gonadotropin (HCG) and luteinizing hormone releasing hormone A 2 (LHRH-A 2 ) 2ug / kg fish body; the second injection dose is dioconone maleate (DOM) 3mg / kg fish body, chorionic gonado...

Abstract

The invention belongs to the technical field of fry breeding and in particular discloses an artificial anabarilius alburnops reproduction method. Hormones are injected to female fishes and male fishesto implement artificial spawning, semidry method artificial insemination is implemented, furthermore, zygotes are uniformly thrown to a medium, and artificial incubation is implemented in a mode thatthe zygotes are adhered to the medium. The method makes up the blank of the prior art, and has the advantages of being simple and convenient to operate, low in cost and high in fertility rate and incubation rate.

Description

technical field [0001] The invention belongs to the technical field of fish fry breeding, in particular to a method for artificial breeding of silver white fish in Dianchi Lake. Background technique [0002] Silver white fish (Anabarilius alburnops) is a unique indigenous species in Dianchi Lake. Due to the introduction of alien species, overfishing and other factors, as well as the rapid development of urbanization and industrialization in Kunming after the late 1980s, industrial, agricultural and domestic pollution has increased, the ecological environment of Dianchi Lake has undergone great changes, and the water quality has deteriorated. , the population of almond fish in Dianchi Lake has decreased sharply and almost disappeared. It has been listed as endangered by the "China Red Book of Endangered Animals-Fish", "China Species Red List Volume 1", "IUCN Red List", and also by Yunnan Province. Listed as endemic rare protected animals. Dianchi silver whitefish used to be...
