The basic ecological features of the benthos Northern Caspian

There are resulted the ecological bases of a biodiversity saving of the sea-bottom organisms of the Northern Caspian

Characteristics of benthos of the North-eastern Caspian Sea, technology of its recovery and impact of the oil and gas extraction on the environment

In the article is in details considered the technology of investigation and an oil recovery in the eastern part of Northern Caspian Sea. It is shown that the most negative influence will test the benthos of the water area. Materials on structure, seasonal dynamics and biomass of groundorganisms of eastern part of the Northern Caspian Sea are resulted

Ecological prognosis modelling of benthos state in the Northern Caspian Sea

There’s made an attempt in the work to estimate the bentos population of the Northern Caspian Sea by mathematic modelling methods. At use of the given method probably considerably to improve the forecast of the general admissible fishes in this area

Mathematical model of fish-productivity estimation in the Northern Caspian on the annual primary production of phytoplankton

In the work there is presented mathematic model of counting the fish catching by measuring the seasonal primary production of phytoplankton of the Northern Caspian. The model has shown its representativeness and is offered to use to specialists
