The globally important whiteleg shrimp or Pacific white shrimp, Litopenaeus vannamei, is an aquaculture species that would benefit substantially from integration of genomic selection into traditional breeding programs, particularly for disease resistance and low heritability traits.

The research team led by Dr. Kong Jie from Chinese Academy of Fishery Science have sequenced 443 varieties for SNP discovery, which provides a foundation for the Molbreeding GenoBaits 55K shrimp panel design. In this design, total 53,128 SNP sites were targeted, including 3,086 functional sites, such as ammonia tolerance, VpAHPND resistance, WSSV resistance, feed conversion efficiency, harvest weight, etc. This panel has been validated in different mapping populations and can be used for research work such as analysis of genetic structure and genetic diversity. This 55K panel is also a great tool for genome selection to improve breeding efficiency of disease resistance and select high-quality varieties of Litopenaeus Vannamei.
