The winter flounder, Pseudopleuronectes americanus, is an esteemed food fish and has sustained an important commercial and recreational fishery for many years in the northeastern United States. Histopathologic examinations of hepatic tissues of winter flounder from Boston Harbor revealed a high prevalence of neoplasms. The lesions, designated as cholangiocarcinomas and hepatocarcinomas, were found in 16 of 200 fish examined and resembled those experimentally induced in rodents by exposure to carcinogens.
The histopathology of fin rot disease in winter flounder, Pseudopleuronectes americanus, from the New York Bight is described. Fin rot in winter flounder was characterized by progressive loss of portions of the anal and dorsal fins. Microscopic findings included epidermal hyperplasia accompanied by dermal fibrosis, hyperemia, and hemorrhage. Bacteria were not observed in situ and a pronounced leukocytic inflammatory response was not noted.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
