Anatoly Andriyashev


Anatoly Petrovich Andriyashev was a Soviet Russian ichthyologist, marine biologist, and zoogeographist, notable for his studies of marine fauna of the Arctic and the Northern Pacific.

Notable dates

Andriyashev is an author of over 230 scientific papers.

Research

Andriyashev focused on ichthyological research in the Far East and the Arctic seas, in the Antarctic and in the different regions of the Pacific, Indian and Atlantic Oceans.
Between 1962 and 1997 he was working to solve problems of biogeography and ecology, and of origins of amphiboreal, amphi-pacific and bipolar distributions of aquatic organisms. In 1953 he worked on the concept of "ancient deep-water" and "secondary deep-water" species and, in 1964, on the zoogeographical zonation in the Arctic and Antarctic.
In 1990 he developed the hypothesis of transoceanic dispersal of "secondary deep-water" species of boreal-Pacific origin to the depths of the north Atlantic and the Arctic. In 1979 he studied the problem of vertical zonation salt-water benthic ichthyofauna; in 1986, the phenomenon of glacial submergence of the Antarctic ichthyofauna from the subtidal zone to depths of 300–600 metres; in 1970, the justification of the form of cryopelagic fish in ice-covered seas; and in 1997, the conception of bionomic bipolarity of marine life.
