Pseudochaenichthys georgianus In the South Georgia icefish, 16 helminth species were recorded (from 3 to 12 species per host), including 3 species of trematodes, 4 species of cestodes, 5 species of nematodes and 4 species of acanthocephalans (table 3). Estimated species richness was 18 (Chao1), 19 (jackknife) or 17 (bootstrap) species. The diversity indices equalled 1.54 (Shannon), 0.68 (Simpson), and 0.55 (Pielou’s evenness). All the cestode species, as well as the nematodes Anisakis sp., Contracaecum sp. and Pseudoterranova sp. and acanthocephalans Corynosoma spp. parasitize P. georgianus on larval stages. Thus, P. georgianus is considered to be a definitive host for 6 out of 16 helminth species recorded. As in the mackerel icefish, cestodes predominated in the helminth community of P. georgianus together they comprised 78.7 % of the total helminth number (fig. 1). According to the prevalence of infection, 8 species predominated in the helminth community in P. georgianus (table 3). Bilocular and ... : Published as part of Kuzmina, T. A., Salganskiy, O.
