Endoparasites of the blue whiting, Micromesistius poutassou from north-west Spain
Abstract The communities of metazoan endoparasites of blue whiting, Micromesistius poutassou , in waters of north-west Spain were analysed and a geographical comparison made with other localities. Four hundred blue whiting collected in July 1999 and September 2000 were examined for parasites, exclud...
