Assessing genetic diversity of a Argyrosomus regius stock using amplified fragment lenght polymorphism analysis

A new interesting species for the diversification of national aquaculture is Argyrosomus regius. It is a very promising species, presenting interesting biological features (growth and larval rearing). The application of DNA markers has allowed rapid progress in aquaculture investigations of genetic variability and inbreeding, parentage assignments, species and strain identification, and the construction of high-resolution genetic linkage maps for aquaculture species. Among the several marker system, amplified fragment length polymorfism (AFLP) is highly reiable for the assessment of genetic variation among and within populations. In this work we evaluated the genetic variation, by using AFLP analysis, of a broodstock of Argyrosomus regius.
