“…As a result, molecular markers and associated tools, such as genetic maps, are currently available for some crustacean species, particularly for shrimps. Molecular markers have been applied, for example, for analyzing the genetic diversity of wild shrimp resources (Xu et al, 2001), for strain and species identification in penaeids (Calo-Mata et al, 2009), and for parentage analysis in the black tiger shrimp Penaeus monodon (Jerry et al, 2006). In addition, linkage maps have been generated for several penaeid shrimp species, in most cases by using amplified fragment length polymorphism (AFLP) (Li et al, 2003;Zhang et al, 2007;Staelens et al, 2008).…”
