Bioproductivity Of The Azov Sea Basin

Abstract
The environmental state of the Azov Sea is determined by a number of factors
among which the influence of river basins plays the leading part. The most
prominent anthropogenic impacts are concentrated within the limits of lower
Don system including the huge Tsymlyansk reservoir, the group of salinized
Manych lakes and ecologically vulnerable Don delta. The environmental
management of this area must be based on the integrated approach to marine and
freshwater objects. This paper presents preliminary results of the ecological
researches carried out in marine and land parts of the Azov basin and
recommendations on the development of monitoring systems as well as some
practical steps for the improvement of water quality and bioproductivity.
Keywords: Azov Sea, Don River, catchment area, monitoring, quality
management.
1 Introduction
The Sea of Azov with its fluvial drainage systems is a unique in many aspects
part of the World Ocean. It includes only insignificant part of both: area and
water amount in the chain of the internal seas, consisting of the Mediterranean,
the Marmora Sea, the Black Sea and the Sea of Azov (Table 1). But it receives
large amounts of fluvial run-off from the drainage system, extending from the
central Russia regions till the northern slope of Great Caucasus. As it follows
from the data in Table 1, annual inflow of fresh water into the Sea of Azov is
more than 10% of its water amount whereas in other seas this index is in the
range from 0.3% in the Marmora Sea to 0.01% in the Mediterranean. This fact
conditions important peculiarities of the Sea of Azov oceanological regime that
is: low salinity, its significant temporal-spatial variability; intensive water
