The parasitic travel of Margaritifera margaritifera in Atlantic salmon gills: from glochidium to post-larva
The larval development of the endangered freshwater mussel Margaritifera margaritifera (L.) represents one of the most unique parasitism among naiads, in which larva parasite the fish gills for several months. Despite the importance of this parasitic phase to successfully culture the freshwater muss...
