HEALTH STATUS OF CHUB (Squalius cephalus) IN RELATION TO WATER QUALITY OF SAVA RIVER
Water quality has infuence on the health status of the organisms living in it. In the available literature, there is only a few reports on the health status of chub, particularly in the Sava river. The aim of this study was to estimate health status of chub as indicator of water quality. Furthermore...
