Black sea bass are a host in the developmental cycle of Lernaeenicus radiatus (Copepoda: Pennellidae): insights into parasite morphology, gill pathology and genetics
Abstract Lernaeenicus radiatus , a mesoparasitic pennellid copepod, has long been known in the northwest Atlantic with metamorphosed females infecting the muscle of marine fish. The study herein is the first to identify a definitive first host, black sea bass Centropristis striata , for L. radiatus...
