“…Microsatellite analyses have been used to assess genetic variation in several penaeid species, such as L. vannamei (Wolfus et al, 1997), Marsupenaeus japonicus (Moore et al, 1999), L. stylirostris (Bierne et al, 2000), Penaeus monodon (Tassanakajon et al, 1998;Brooker et al, 2000;Pongsomboon et al, 2000, Xu et al, 2001, Litopenaeus schmitti (Maggioni et al, 2003;Borrel et al, Genetics and Molecular Biology, 30, 4, 1156-1160(2007 Copyright by the Brazilian Society of Genetics. Printed in Brazil www.sbg.org.br 2004) and Litopenaeus setiferus (Ball and Chapman, 2003) but, however, little is known on the genetics of the Brazilian L. vannamei broodstocks Galetti Jr 2002, 2005;De Francisco and Galetti Jr, 2005;Gonçalves et al, 2005).…”
