Epidemiology of Ulcerative Mycosis in Atlantic Menhaden in the Tar-Pamlico River Estuary, North Carolina

Ulcerative mycosis was observed on Atlantic menhaden Brevoortia tyrannus collected in pound-net and trawl samples obtained from the Tar-Pamlico River estuary, North Carolina, during May 1985-April 1987 and in cast-net samples obtained during October-November 1986. The disease was most prevalent on Atlantic menhaden caught in pound nets during November 1986 and January 1987, and in trawls during May 1986 and November 1986. Disease was also most prevalent among yearlings in the spring and was probably acquired in the estuary.
