The occurrence of the parasite Eubrachiella gaini Quidor, 1913 in Antarctic fishes of the family Chaenichthyidae

Abstract

Infestation of five chaenichthyid species with Eubrachiella gaini (Copepoda Parasitica) was studies in the Atlantic sector of Antarctica in 1978/1979. A total of 6321 fish individuals were examined in detail. Invasion incidence and intensity of each species is presented and related to the fishing areas visited. Frequency of the parasite′s occurrence on various parts of the host′s body is analysed. An attempt is made to relate the degree of infestation to fish body length in the fish species studied.
