Fin erosion in winter flounder

Diseased fish showing erosion of the fins have been recorded from polluted waters in several parts of the world. This article gives the results of a year's survey of fin erosion among fish in oceanic and estuarine waters of New York Bight. The pristine Great Bay was chosen as a control for the heavily contaminated Sandy Hook-Raritan Bay system. Almost all fin erosion was confined to demersal flat fish, particularly the winter flounder, a species which spends a long time in polluted estuaries near Sandy Hook.
