Efficient breeding method for high-quality abalone seedlings high in environmental adaptability

Abstract

The invention discloses an efficient breeding method for high-quality abalone seedlings high in environmental adaptability. The efficient breeding method includes: (1) selecting seedlings: selecting healthy abalone seedlings; (2) cultivating adaptability of the abalone seedlings: breeding the abalone seedlings in a breeding pond with a water temperature ranging from 20 DEG C to 22 DEG C for 7 days; (3) domesticating and selecting abalone seedlings: rising up the water temperature by 1 DEG C every day till the water temperature reaches to 28-29 DEG C, maintaining the water temperature for 10-15days, observing growing situations of the abalone seedlings every day, clearing up dead abalone seedlings, lowering the water temperature to 24 DEG C gradually after the 10-15 days, and maintaining the water temperature; (4) repeating the domesticating and selecting step in the step (3) once every two months till the abalone seedlings grow maturely. The efficient breeding method for the high-quality abalone seedlings high in environmental adaptability has the advantages that through adaptability cultivating, the abalone seedlings just put into the breeding pond are enabled to adapt to an environment in the breeding pond, the post domesticating and selecting steps can be implemented conveniently, before the abalone seedlings grow maturely, the abalone seedlings are subjected to multiple times of domesticating and selecting, the abalone seedlings irresistible to high temperature are screened out, and the abalone seedlings resistible to the high temperature can be cultivated and selectedefficiently.

Description

technical field [0001] The invention relates to the technical field of abalone culture, in particular to a high-efficiency culture method for high-quality abalone fry with good environmental adaptability. Background technique [0002] Abalone is a precious seafood treasure that has always been favored by consumers; the abalone breeding industry is not only an important fishery industry, but also a typical agricultural industry that is related to social stability and directly meets people's basic living needs. After more than 10 years of rapid development, my country's abalone breeding industry has leapt to the top in the world, with an annual output of more than 100,000 tons of finished abalone, accounting for more than 90% of the total global abalone production, directly bringing benefits to coastal fishermen 80,000 to 100,000 employment opportunities and more than 2.5% of fishery economic income have created huge economic, social and ecological benefits.

Problems solved by technology

Although this method is effective, it is time-consuming, laborious, and has certain risks and limitations. The fundamental solution to the problem is to obtain the "high temperature resistance" and high-growth traits of abalone seedlings through introduction or genetic improvement.
