In the present study the macroparasite assemblage infecting Helicolenus dactylopterus (Delaroche 1809) in three different areas off the Portuguese coast was evaluated in order to assess their use as biological tags in stock identification Fish were obtained from commercial landings in Azores Madeira and mainland Portugal (Peniche) and were examined for macroparasites infections according to standard procedures Parasite assemblage composition and the prevalence and mean abundance of each macroparasite taxa within each area were calculated Amongst the 20 taxa found 13 were selected as good biological tags presenting statistically different infection levels between areas Anisakidae larvae which presented different prevalence and mean abundance levels between the three areas were further identified according to the restriction fragment length polymorphism (RFLP) pattern on Taql Hinfl and Hhal The multivariate discriminant analysis applied to the macroparasites species present in more than one area and showing prev
