Fishes of the Bellingshausen Sea and Peter I Island

The unknown benthic ichthyofauna of the Bellingshausen Sea was analysed. Some data concerning the ichthyofauna of Peter I Island were also included. A total of 583 specimens belonging to 32 species were collected mainly by an Agassiz trawl and baited traps set between 86 and 1,947 m depth. A total of 72.2% of the specimens (89.0% of them Nototheniidae) were caught with the Agassiz trawl, whereas 27.8% of the individuals (90.1% of them Zoarcidae) were captured with traps. The Bellingshausen Sea ichthyofauna was dominated by Zoarcidae (43.9% of individuals, 35.8% by weight) and Nototheniidae (43.0 and 15.2%, respectively). Twenty-two of the 23 species captured in the Bellingshausen Sea are reported for the first time from this area. Trematomus scotti was the dominant nototheniid in the Bellingshausen Sea whereas Lepidonotothen larseni was dominant off Peter I Island.
