translate English to French: (The species of this host fish is still unknown but, partly because of the large historical range of this mussel, it is believed that a number of different species might actually be involved.)
L'espÃ¨ce de ce poisson hÃ´te est encore inconnue mais on suppose qu'il pourrait d'agir de plusieurs espÃ¨ces, en partie Ã cause de la grande aire de rÃ©partition historique de la moule.
