The bogue is host to a wide variety of parasites, ranging from metazoans such as monogenean flatworms (e.g. "Microcotyle isyebi"), acanthocephalan spiny-headed worms, nematode roundworms, isopod and copepod crustaceans and myxozoan cnidarians to the unicellular dinoflagellate "Ichthyodinium chabelardi", a parasite lethal to eggs developing in ovaries. At least 67 metazoan parasite species have been reported from the species. In the aftermath of the 2002 Prestige oil spill, the community of parasitic species inhabiting bogue caught off the coast of Spain was noticeably altered.
