The Caspian seal (Pusa caspica) has declined by more than 90% since 1900 and is listed as endangered by IUCN. We made the first quantitative assessment of Caspian seal by-catch mortality in fisheries in the north Caspian Sea by conducting semi-structured interviews in fishing communities along the coasts of Russia (Kalmykia, Dagestan), Kazakhstan and Turkmenistan. We recorded a documented minim...

Russia after the collapsing of Soviet Union ignored and left behind the Caspian Sea for a short time due to giving preference to relationship with West. Discovery of new sources of energy in the Caspian region and the significance of the geopolitical position of this region in Europe, Asia and the Middle East and the key role that plays in the power balances in the world, also West attention sp...

The European river lamprey came to the Upper Volga from Baltic Sea most probably via a system of shipways developed in 18th and 19th centuries. Vyshnii Volochek, Tikhvin, Mariinskaya water systems are possible invasion pathways for this species. Dispersal colonization Caspian Basin was likely combination upstream downstream migrations. Analysis museum our own samples showed that possibly migrat...

In Caspian Sea basin, sturgeons spend the larval and juvenile stages in freshwaters of rivers and then, they migrate to brackish waters of the sea where they grow and mature. With regard to the elevation of the metal concentrations in coastal waters and sediments of the Caspian Sea and its adjacent rivers, it is likely that juvenile sturgeon are exposed to sub-lethal levels of metals during sea...

Mesacanthus is a common and speciose genus of acanthodian fish from Lower Old Red Sandstone and Middle Old Red Sandstone assemblages (representing the Lower Devonian and Middle Devonian respectively) and is well represented in many palaeoichthyology collections in the UK. Based upon descriptions given during the 19th century, specimens of the genus Mesacanthus from the Orcadian Basin and Midlan...
