The study was carried out at sites of contrasting environmental conditions: exposed rocky shores, protected shores, protected and polluted areas, and culture area. Two species of parasitic copepods were found inhabiting the mantle cavity and gills of mussels: Pseudomyicola spinosus (Mycolidae) and Modiolicola gracilis (Clausidiidae). This is the first record of these copepods in Mexican waters. M. gracilis was found in M. galloprovincialis and M. californianus from all localities studied. Its presence was relatively constant through the year. P. spinosus, by contrast, was scarce or absent in M. californianus and M. galloprovincialis from exposed rocky shore environments. Its number and prevalence were low in the mussel culture area. However, it was very abundant in M. galloprovincialis from the protected and polluted environments. Rates of infestation in mussels increased in autumn.
