Abstract

Recurrent infection of captive meagre, Argyrosomus regius, by a monogenean parasite has been observed in the broodstock facilities of Institut de Recerca i Tecnologia Agroalimentàries (IRTA) in Catalonia, Spain, between 2008 and 2015. Following handling procedures related with hormonal treatment for spawning induction, one fish died. Post-mortem examination and detailed microscopical examination using light microscopy, SEM, and histology revealed intense infection by Diplectanum sciaenae (Monogenea, Diplectanidae) which caused noteworthy gill pathology. In the present study, we provide detailed description of the parasite and the pathology caused to its host. This is the first report associating this parasite with disease and mortality in farmed meagre.
