Last decades many investigations were focused on the design of the efficient system of water monitoring capable to evaluate the degree of human influence. The monitoring system is an important part of the management system and the main objective of status assessment is to provide data for design of effective measures for prevention of further deterioration and status improvement. Despite the European trend to promote biological investigations as an important part of the assessment system (Water Framework Directive, WFD – EC 2000), biological methods have been unjustifiably neglected in the water quality monitoring systems in many countries, including Republic of Macedonia. The aim of the current study was to set up and the evaluation of the water quality of the Pčinja River based on the structure of the fish community. The results of the study presents solid basis for testing the efficiency of the EFI index in R. Macedonia.
