Problems solved by technology

[0002] Since traditional abalone artificial breeding has been accompanied by various diseases since the beginning of breeding, such as muscular dystrophy, impetigo disease, air bubble disease and other viral diseases, the mortality rate of abalone artificial breeding is as high as 80-90%, and the incidence of viruses is almost Moreover, the large-sized abalone seedlings after stripping accounted for only 15% of the total, the medium-sized ones accounted for 50%, and the small-sized ones accounted for 25%. It is not difficult to see that the current artificial breeding of abalones is seriously threatened by the virus. Therefore, even if the amount of water survives, the specifications of abalone fry are still unsatisfactory

specific Embodiment approach

[0009] Specific embodiments, the following implementation examples are further descriptions of the present invention:

[0010] Embodiment: With New Zealand black golden abalone as the female parent and Chinese corrugated plate abalone as the male parent, in a pond with an area of ​​4858 square meters, abalones are planted to promote ripening, to induce oviposition, and to hatch on March 8-April 8 on 6 The seedlings were collected under the condition of ~8°C, and the plates were transferred three times during the diatom feeding stage, once for 55 days, for a total of 165 days, and then 35 million abalones were stripped out, and after advection feeding and bait technology stages, they were screened twice and finally cultivated into There were 27.8 million commercial seedlings, including 23.63 million large-sized seedlings, 2.224 million medium-sized seedlings, and 1.39 million small-sized seedlings.

Abstract

The invention relates to an artificial breeding method for abalone, and the method is capable of resisting viruses and diseases and improving the specifications of abalone fries. The method comprises the steps of maturity promotion of parent abalone, spawning induction, incubation, fry collection, breeding with diatom, stripping, advection breeding, application of fish-bait techniques and obtainment of commercial abalone fries. The method has the following characteristics: hybridization is carried out with New Zealand Black Gold as a female parent and Chinese Haliotis discus Hannai as a male parent in the stage of maturity promotion of parent abalone; abalone fry collection time is advanced, abalone fry collection is lowered down, the area of abalone fry collection is halved, the time for breeding with diatom is prolonged and the scale of stripping is enlarged. The artificial breeding method for abalone provided by the invention greatly improves the survival rate and the scale of the artificial breeding of abalone and enhances economic benefits.

Description

technical field [0001] The invention relates to an artificial seedling raising method for aquatic products, in particular to an artificial seedling raising method for abalone. Background technique [0002] Since traditional abalone artificial breeding has been accompanied by various diseases since the beginning of breeding, such as muscular dystrophy, impetigo disease, air bubble disease and other viral diseases, the mortality rate of abalone artificial breeding is as high as 80-90%, and the incidence of viruses is almost Moreover, the large-sized abalone seedlings after stripping accounted for only 15% of the total, the medium-sized ones accounted for 50%, and the small-sized ones accounted for 25%. It is not difficult to see that the current artificial breeding of abalones is seriously threatened by the virus. This means that even if the amount of water survives, the specifications of abalone fry are still unsatisfactory. Contents of the invention [0003] The purpose o...
