Observations of Ulcerative Mycosis Infections on Atlantic Menhaden ('Brevoortia tyrannus')

摘要

The report summarizes observations of ulcerative mycosis (UM) infections of Atlantic menhaden (Brevoortia tyrannus) that were made ancillary to juvenile abundance sampling and tagging activities. Varying degrees of UM infection of the 1982-86 Atlantic menhaden year classes are noted. Geographic areas of primary infection are tentatively identified and distinguished from areas where immigration of diseased individuals hypothetically occurred. Problems associated with sampling for UM incidence levels and for determining the impact on the Atlantic menhaden population are discussed.
