The effect of water-soluble fraction of diesel oil on some hematological indices in the great sturgeon Huso huso.
Hematological and Immunological parameters of aquatic animals may be changes due to acute, subacute and chronic exposure to marine pollutants. The purpose of this study was to determine the experimental effects of water-soluble fraction (WSD) doses (0, 10, 100, 500 and 1,000 ppm) for 0, 48 h and 7 days on hematological and immunological features of juvenile great sturgeon Huso huso. Fish exposed after 48 h and 7 days showed a significant change in the white blood cell (P < 0.01) in contrast to red blood cell (P > 0.05). Only MCV, neutrophil and lymphocyte show significant change within 48-h exposure to WSD (P < 0.05), whereas among significant indices, MCV and lymphocyte had been decreased and neutrophil had increased. Seven-day exposures showed a significant change in MCV, neutrophil, eosinophil and lymphocyte concentration in relation to the respective control (P < 0.05), whereas among significant indices, neutrophils were significantly greater and MCV, eosinophil and lymphocyte were significantly lower than those in control groups (P < 0.05).
