Abstract

The objective of this work was to assess polymorphisms within Litopenaeus vannamei candidate genes related to growth performance, and a possible association between weight genotypes and phenotypes in two shrimp closed lines. Three EST-SSR (serine-arginine, 60S ribosomal, and troponin) and one EST-SNP (crustacyanin) were selected and evaluated in L. vannamei and seven other marine shrimp species, besides two freshwater species. Genotypes had no effect on total body weight. Although no association was observed in the sampled population, these markers showed amplification for most of the evaluated species and, therefore, may be useful in further genetic studies on shrimp species.
