The Pacific white shrimp, Litopenaeus vannamei (Penaeidae), represents about 95% of all Brazilian shrimp production. The Brazilian L. vannamei foundation broodstock was made up of specimens collected from different American Pacific sites, but little information was collected on the genetic structure of the broodstock. We used the fluorescence amplified fragment length polymorphism (fAFLP) method to study the genetic diversity of L. vannamei broodstock lines 03CMF1 and 03CBF1 originally produced by breeder-shrimps imported mainly from Panama and Ecuador, although wild individuals from other localities may also have been used in producing these two lines. Our results showed a total of 93 polymorphic bands ranging from 50 to 500 bp, the mean Nei's genetic... |

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. |
