Embodiment Construction

[0020] The technical solution of the present invention will be further described below in conjunction with the examples.

[0021] The present invention has been implemented and applied in the Aquatic Genetics and Breeding Center of the Yellow Sea Fisheries Research Institute of the Chinese Academy of Fishery Sciences. The technical methods of the present invention include: 1. Secondary seed cultivation; 2. Tertiary cultivation; 3. Secondary shrimp cultivation .

[0022] 1. Secondary seedling cultivation

[0023] The secondary seed cultivation is divided into two stages, H1 and H2. H1 is the cultivation stage from the nauplius hatched after spawning of broodstock without specific pathogens to metamorphosis to the fourth day of larvae, and H2 is the cultivation stage of larvae from the fifth day to the larvae. The cultivation stage on the twentieth day. The cultivation water in the secondary seed cultivation stage is treated in the following way: the natural seawater first ent...

Description

technical field [0001] The invention belongs to the technical field of prawn cultivation and relates to a method for graded cultivation of Litopenaeus vannamei without specific pathogenic species. Background technique [0002] Litopenaeus vannamei is an important seawater economic shrimp. It is native to the Pacific coast of South America. It has a long breeding period, strong adaptability to the environment, low nutritional requirements, large individuals, fast growth, and strong disease resistance. Long survival time out of water, easy to transport and sell live shrimp, thin shell, thick and delicious meat, high meat yield after processing, etc. In 1988, the Institute of Oceanology, Chinese Academy of Sciences introduced it to my country from Hawaii, USA. After a breakthrough in artificial propagation technology, it began to be widely cultivated throughout the country. The current aquaculture output accounts for more than 80% of the national prawn aquaculture output. At p...
