Abstract

“Tikves” is one of the largest artificial reservoirs, which has been built with constraining of River Crna near the town of Kavadarci. This reservoir is a hydro energetic and irrigation system that is exploited for sports and economic fishery.
In the accumulation Tikves (a.k.a. Lake Tikves) there are to be found 20 different species of fish, representatives of 7 families.
During the summer period of 2011, in the reservoir Tikves, from the locality Resava Bay, a total of 12 of fish specimens have been caught, which were classified in 6 different species (Carasius gibelio, Rutilus rutilus, Ameirus nebulosus, Perca fluviatilis, Vimba malanops, Silurus glans). Out of each specimen there have been dissected a piece of gills for histological analysis, which, thereafter has been processed on the standard procedure for development of histological preparation. They have been analyzed under a microscope and the registered tissue lesion has been photographed.
Based on standard histopathological analysis some gills lesions were detected. Microscopic analysis has revealed a series of circulatory, regressive and inflammatory changes. The most prominent were necrosis of respiratory epithelium accompanied by collapsed secondary lamellae and infiltration with eosinophiles in respiratory epithelium. Some structural lesions in gill tissue have been accepted as valid biomarkers of anthropogenic stress at fish.
