CHANGES IN BLOOD PARAMETERS OF GRASS CARP CTENOPHARYNGODON IDELLA (VALENCIENNES, 1844) FINGERLINGS UNDER THE EFFECT OF CHLOROFETE

The present study has carried out to clarify the changes of blood parameters grass carp Ctenopharyngodon idella (Valenciennes, 1844), responding chlorofete effect under laboratory conditions, in presence and absence aquatic plant Ceratophyllum demersum (L.). Three concentrations used during chronic exposure time extended (15days). Blood tests (R. B. Cs., Hb, P.C.V.) were studied for fish exposed concentration investigated. hematological decreased with increasing pesticide concentrations. Moreover, values indices (M.C.V.) showed significant increase concentration, particularly at highest (3.8) mg/l (5, 6 9) days plant. However, apparent (M.C.H.) observed especially (6 time. Significant recoded treatment (7 10) mg\l (10) (M.C.H.). nonsignificant reduction (M.C.H.C.) both treatments without
