Genetic Characterization of Six Stocks of Litopenaeus vannamei Used in Cuba for Aquaculture by Means of Microsatellite Loci
Four microsatellite loci were used to achieve genetic characterization of six stocks from Litopenaeus vannamei used for aquaculture in Cuba: second generation from first introduction (S2-1), first generation from the second one (S1-2), from the third one (S1-3), and the fourth one (S1-4) and the cro...
