Observations on the localization and pathogenicity of Haemobaphes diceraus Wilson; 1917 (Copepoda: Lernaeoceridae) in the gills of Theragra chalcogramma (Pallas)

[摘要] The invasion of Theragra chalcogramma by the parasitic copepod Haemobaphes diceraus and the anatomo-pathologic changes induced by these parasites in the organs of the host are described. The data concerning H. theragrae Yamaguti, 1939 and H. enodis Gusev,1951 are also discussed and the supposition as to their synonymy with H. diceraus Wilson, 1917 is put forward.
