Visual observations of fish from seamounts of the Southern Azores region (the Atlantic Ocean)

Article

Abstract

Results of observations from the underwater inhabited device “Sever-2” of the behavior and distribution of fish on seamounts of the Azores region up to a depth of 1200 m are provided. In the natural habitat, 52 species of fish of 46 genera belonging to 36 families were recorded. In the ichthyofauna of the studied region, bottom (37.0%) and near-bottom (29.2%) species dominate; the proportion of off-bottom and off-bottom-pelagic species is 18.0 and 12.4%, respectively, and pelagic species account for only 3.4%. Pelagic species Scomber japonicus and Trachurus picturatus; off-bottom-pelagic Beryx splendens, Lepidopus caudatus, and Aphanopus carbo; and near-bottom species Zenopsis conchifer, Macrorhamphosus scolapax, Antigonia capros, Capros aper, Anthias anthias, and Callanthias ruber dominate by numbers and the amount of biomass.
