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

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
