Genomic DNA was extracted from ten shrimp of the Pacific white shrimp or Litopenaeus vannamei species and used to find single nucleotide polymorphisms (SNPs) in the Alpha-amylase (_-AMY) and the Cathepsin-L (CTSL) genes. This study lays the groundwork for future research to examine the association of genetic markers and the growth rate of farm raised pacific white shrimp.
