Artificial fry breeding method for yellow lip fish

Abstract

The invention provides an artificial fry breeding method for yellow lip fish. The artificial fry breeding method comprises the steps of setting of spawning induction and hatching environment factors of the yellow lip fish, determination of spawning induction dosage forms, setting of fry breeding environment factors, setting of larva and juvenile fish biological baits, nutrition enhancement and a mixed feed feeding strategy. The method comprises the following steps: 1, inducing spawning by adopting pituitary extract of Sciaenidae fish and chorionic gonadotropin; illumination, sound waves and salinity in environmental factors in the spawning induction stage are set, and after aging is carried out for 40 hours, natural spawning, spermiation and insemination are carried out. And 2, regulating and controlling a biological bait nutrition enhancer, and regulating and controlling the change of salinity, water temperature and illumination in the growth and development stage of the larvae and juvenile fishes and the change of water flow stimulation. According to the method, the technical bottleneck that artificial breeding of the classocheilus flavipes in China cannot be successful in decades is broken through, the blank of breeding of large-scale sciaenidae fishes at home and abroad is filled up, and the method has a positive promoting effect on germplasm protection and resource recovery of the first-grade endangered species, namely the classocheilus flavipes, in China.

Description

technical field [0001] The invention belongs to the field of artificial breeding of large totoaba fish, and particularly relates to a technical method and application of artificial breeding of yellow lip fish. Background technique [0002] The seed industry project in the aquaculture industry is the top priority of the development of the aquaculture industry in my country today. Mastering high-quality germplasm resources, providing high-quality seed and restoring natural resources through artificial breeding, is very important for the construction of blue granary and the protection of marine ecology. Environments are both practical and strategic. At present, most of the varieties of marine fish breeding in my country are concentrated in small and medium-sized fish, such as red sea bream, black sea bream, flounder, oriental puffer, oval pomfret, large yellow croaker, and perch. Limited by the lack of large fingerling resources, and also limited by the corresponding facilities...

Problems solved by technology

[0003] Yellow-lipped fish is a large fish in the cichlidae family, and it is also a unique economic species in my country. Yellow-lipped fish has special requirements for the ecological environment, but the environmental conditions of the original habitat can no longer meet the requirements for its growth and survival. Coupled with the disorderly fishing for more than 20 years, the natural resources have decreased sharply, and it has been listed as a national first-class endangered animal.
