Method for improving reproductive performance of crassostrea hongkongensis by using L-acetylcarnitine and application

The invention relates to the technical field of aquaculture, in particular to a method for improving the reproductive performance of Crassostrea hongkongensis by using L-acetylcarnitine and application of the Crassostrea hongkongensis, the Crassostrea hongkongensis is treated in two modes of treating Crassostrea hongkongensis parents and Crassostrea hongkongensis gametes by using the L-acetylcarnitine, and the reproductive performance of the Crassostrea hongkongensis is remarkably improved through the two modes. The hatching rate is obviously improved; experiments show that when L-acetyl carnitine with the final concentration of 150 mg/L is adopted to treat parents under the condition that the seawater salinity is 12% o, the hatching rate of oysters is increased to 71.88% from 16.25% of a control group, and is increased by 3.42 times; after the sperms and the eggs of the oysters are mixed and soaked for 15 minutes under the condition that the salinity of seawater is 12% o by adopting L-acetylcarnitine with th
