Abstract:

The purpose of this study was to determine the effect of the insecticide lesenta on several haematological markers of common carp (Cyprinuscarpio L.). A sublethal dose of 0.12, 0.25, and 0.5 µg/L was administered on the seventh, fourteenth, and twenty-first days of exposure, respectively. The RBC count in group IV fishes (0.5 µg/L lesenta treated) reduced from 6.83+0.53 to 44.00+0.82 (x106 mm-3) after 21 days of exposure, and this decrease is statistically significant (p<0.01) when compared to control fishes. The higher WBC count in group IV (0.5 µg/L lesenta) treated fish at 21 days of exposure ranged from 4.45+0.16 to 7.70+0.60, which is statistically significant (p0.001) when compared to the control. The decrease in Hb level of treated fish may indicate a decrease in Hb synthesis as well as a decrease in oxygen carrying capacity, which could be caused by lesenta interfering with the haem or globin production pathway. This study concluded that acute exposure to lesenta resulted in a significant decrease (p<0.05) in RBC, WBC, and Hb content levels for the fish compared to the control groups. The decrease in values obtained for hematological parameters of treated fish in this study indicated that the physiological activities of the treated fish were impacted.
