Infestation of the blue mussel Mytilus galloprovincialis by the copepod Pseudomyicola spinosus and its relation to size, density, and condition index of the host
The copepod Pseudomyicola spinosus infests marine mussels and other commercial bivalve species. There is a lack of information on the infestation process and on its relationship to size, density, and health of the host. To obtain this information, an infestation study of the copepod in Mytilus gallo...
