TRANSFORMATION OF THE ECOTONE ICHTHYOCENOSIS UNDER UNSTABLE HYDROECOLOGICAL INDICES (BY THE EXAMPLE OF MOLOCHNYI LIMAN)
Journal Title: Водні біоресурси та аквакультура - Year 2017, Vol 1, Issue
Abstract
The issue of changes in ichthyocenosis under dynamics of hydroecological regime is presented by the example of Molochnyi Liman that refers to ecotone bodies of water. The situation existing for the liman ecosystem confirms that the majority of natural and anthropogenic factors provide a significant effect on the hydroecological processes and structure of ichthyocenosis. The most influential among them are salinity, runoff, water exchange between the ecotone and sea, and hydrometeorological conditions. This paper considers transformations in the ichthyocenosis of Molochnyi Liman under various types of the liman-sea connection. A clear dependence of the fish species richness on salinity level is shown. For these indices, a negative correlation was found at the level of 0.94.
