This study aims to carry out ecological monitoring of the surface water of the Parvenetska River (Eastern Aegean Sea region, Southern Bulgaria). For the study, samples of macrozoobenthos were collected in the spring of 2024 – a basic biological quality element according to the Water Framework Directive. The taxonomic affiliation of macroinvertebrates was determined, and 26 taxa were ident3ified. The number of EPT taxa, % (Oligochaeta & Diptera), % Filtering feeders, % EPT taxa, German trophic index, and species diversity indices were calculated. As a result of the study, it was established that in the studied biotope, macroinvertebrate taxa of sensitivity group C (relatively tolerant forms) dominate, followed by taxa of group B (less sensitive forms).
