The experiment was conducted to evaluate the hematological effect of cypermethrin, a
synthetic pyrethroid on Anabas testudineus. The effect was assessed based on the comparison results
of control group and experimental groups exposed to sublethal concentrations (0.015, 0.030, 0.045 mg
L-1) of cypermethrin on 7th, 14th and 21st days. It was observed that with the increase of cypermethrin
concentration, Red Blood Cell (RBC) counts, hemoglobin (Hb) levels, hematocrit (Hct) levels and
thrombocyte (platelet) counts decreased. White Blood Cell (WBC) counts increased on 7th day of
exposure but WBC counts decreased with the increase of cypermethrin concentrations after 14th and
21st days. The results are statistically significant at p < 0.05 level. These reports indicate that
hematological parameters may be useful as a diagnostic test for cypermethrin exposure in A.
testudineus.
