Parasite communities of Merluccius hubbsi from the Argentinian-Uruguayan common fishing zone

This study is based on parasitological examinations of 159 specimens of Merluccius hubbsi (common hake) from the Argentinian-Uruguayan common fishing zone between June and December 1993. The examination extended the list of parasite species previously known from this host in the study area to the fo...

Description
Summary:This study is based on parasitological examinations of 159 specimens of Merluccius hubbsi (common hake) from the Argentinian-Uruguayan common fishing zone between June and December 1993. The examination extended the list of parasite species previously known from this host in the study area to the following taxa: Anthocotyle merluccii van Beneden and Hesse, 1863; Chondracanthus palpifer Wilson, 1912; Neobrachiella insidiosa f. lageniformis Kabata, 1979; Trifur tortuosus Wilson, 1917; cysts of unknown etiology in gills; Corynosoma spp.; Grillotia spp.; Hepatoxylon trichiuri Holten, 1802; Anisakis spp.; Pseudoterranova spp.; Contracaecum spp.; Hysterothylacium spp.; Microsporidium ovoideum Thélohan, 1895; Elytrophalloides oatesi Leiper and Atkinson, 1914; Derogenes varicus Müller, 1784; Clestobothrium crassiceps Rudolphi, 1802; Scolex polymorphus Müller, 1784; Gorgorhynchidae gen. spp.; Aporocotyle argentinensis Smith, 1969; Kudoa rosenbuschi (Gelormini) Szidat, 1966. The prevalence and intensity of infestation were calculated for each parasite species as related to the body size and sex of the host. The distribution pattern of parasites in hake was also analyzed. Parasite communities of hake examined in the present paper comprises one group of parasite species specific at host family, genus or species level, and another belonging to the local fauna. Component and satellite parasite species were also found.
