Perch (Perca fluviatilis) suitability as a water indicator was studied in field and laboratory investigations. It was found out that hematological status of this fish species was a valuable indicator of both temporary and periodical deterioration of dissolved oxygen saturation and can be used as reliable test for water quality evaluation. The anlyzed hematological parametrs were tested for their sensitivity and reliability as indicators of water quality changes. Values of different parameters were given for perch kept under optimal and unfavourable conditions of water oxygen saturation.
