Application of biotic indices and body size descriptors of phyto and zooplankton communities in Varna lagoon for ecological status assessment

Abstract

The present paper is aimed at: 1 - application of biotic indices to assess the ecological state of Varna lagoon by investigating the response of biota to the gradient of environmental pollution 2 - test applicability of individual body size class distribution of plankton communities as innovative quality element descriptor analyzed against routine plankton quality attributes. Quantitative assessments, seasonal variations and distribution of the plankton community have been analyzed.
