Laboratory Assistant – Scherbakov Aleksandr E.

The laboratory was organized in 1970.

Major trends of research

  • Modern and historical biogeography of freshwater and saltwater fishes of basins in the Far Eastern seas of Russia (fauna, taxonomy, phylogeny, distribution, taxonomical and ecological diversity).
  • Population biology and ecology of fish groups dominating in salmon ecosystems in the North-East of Russia and their economic significance (salmon, chars, grayling, pickerel, whitefishes, smelt and others).
  • Biology of mass coastal fishes and mollusks of the northern part of the Sea of Okhotsk.
  • Development of scientific basis of biodiversity conservation of freshwater and saltwater coastal fishes in the North-East of Russia.

 

Main research achievements of the Laboratory

  • Hypothesis of Beringia freshwater ichthyofauna formation was developed on the basis of the study of modern and fossil fish species composition, peculiarities of their distribution, taxonomy, relationships and ecology. Taxonomical and ecological diversity of the freshwater ichthyofauna of the North-East of Russia was estimated. Some practical recommendations and approaches to the study and conservation of ichthyofauna were offered.
  • Biogeographical analisys was conducted, and a new hypothesis of Russian Far-East freshwater ichthyofauna formation was suggested. Some principal differences in ichthyofauna’s composition and ways of its formation in the north-eastern part (North-East of Russia) and southern part (South-East of Russia) were shown. These differences were defined by geological history of the surface and hydronet development of the region at the end of tertiary and in quaternary periods. Application of different biogeographical theories (vicariant and dispersal) for explaining of peculiarities of freshwater fish distribution in the Russian Far East and adjacent territories of Asia and North America were shown.
  • New scheme of zoogeographical zoning of Holarctic freshwater basins based on the freshwater fishes’ distribution was worked out; new transitional area between Palaearctic and Neoarctic Beringia regions was defined.
  •  A series of researches of the young whitefish’s biology in the basin of the Anadyr’ river was made. On the basis of experimental data and field observations the young fish external morphology was described, the keys for identification of the young fish were charted. Peculiarities of the young fish’s biology during early ontogenesis were studied. Number of different species of the young whitefish was estimated, and some factors defining dynamics of their activity during downstream migration from the spawning area were revealed.
  • Results of the long-term study of the fresh-water fishes’ biology in the basin of the Anadyr’ River were summed up. Study history of the Anadyr’ fishes, biogeographical status and ways of basin ichthyofauna formation. Some data on distribution, biology peculiarities, economic and scientific importance of fish species were represented. Conservation measures and approaches to rational use of the Anadyr’ ichthyofauna were suggested.
  • Study results of economically important salmon fishes in the North-East of Russia were summarized. For the first time complete morphological and karyological description of salmon fishes, as well as information about their distribution, peculiarities of their biology and habit of life, their economic importance, was given.
  • The long-term monitoring of the Chum salmon’s stock in the Anadyr’ River (1971-2012) allowed revealing  regularity of its dynamics resulted in changes of population structure, biological parameters of fish depending on climatic and biocenotic factors during the freshwater and saltwater periods of life.
  • Study results of the fossil fishes from Miocene sediments of the Agnevsk suite (Sakhalin island) were summed up. Community of those fishes included 27 species from 26 genera 16 families 12 suborders and 6 orders. Diagnoses and descriptions of the discovered taxa were given, their phylogenetic relationships and position in the system were revealed; the community structure and ecological characteristics of the fishes were reconstructed. 17 species, 12 genera and 1 family of Miocene fishes were described as new for science.
  • Species composition of ichthyofauna from the basin of the northern part of the Sea of Okhotsk and some of its large bays (Tauisk Bay) was defined. Several big groups of fishes were defined as new for this region, for science and for the Far-Eastern seas of Russia. The taxonomic and ecological diversity was estimated. Large collection of the fresh-water fishes (more than 100 species) and the salt-water fishes (about 250 species) of the North-East of Russia was organized. Most of the species were presented by series of specimens that allows studying of different issues of the fish morphology and biology.
  •  Results of studying of fauna, systematics and biology of Zoarces eelpouts (Zoarcidae, Perciformes) of the northern Sea of Okhotsk, represented by three species – Fedorov’s eelpout (Z. fedorovi), Andriyashev’s eelpouts (Z. andriashevi) and eastern eelpout (Z. elongatus) were summarized. Complex comparative-morphological and molecular-genetic (analysis of mtDNA variability) study of species of the northern Sea of Okhotsk and other species of Zoarces genus of the world fauna (Z. viviparus, Z. americanus and Z. gillii) showed different divergence level of species taxa and presence of several phylogenetic lines inhabiting different areas of the genus habitat. Peculiarities of distribution area, seasonal and biotopical allocation, population structures, characteristics of growth, maturation, breeding (by viviparity), feeding of the eelpouts of the northern Sea of Okhotsk, are described. Keys for eelpouts from the studied areas and in general from the world fauna of Zoarces genus have been compiled.
