Characterization of Blood Cells and Hematological Parameters of Yellowfin Sea Bream (Acanthopagrus latus) in Some Creeks of Persian Gulf

In this study we detect different levels of blood cells and hematological parameters in five creeks of Mahshahr region in North West of Persian Gulf with different levels of pollutant to characterized hematological response of Yellowfin seabream to environmental pollutant and undesirable materials. Numbers of Blood leukocytes was performed by a hemocytometer Neubauer under the light microscope. The leukocyte differential count was made in peripheral blood smears, giving the neutrophils value of differential neutrophils and the mononuclear value of differential lymphocytes plus monocyte and eosinophile. Hematocrit values were determined in a microhematocrit centrifuge. Hemoglobin levels were determined colorimetrically by measuring the formation of cyanomethemoglobin. Result declared significance increase of differential monocyte and neutrophil within higher considerable values than those of the clean station, beside significance decrease of Hb, Ht, leukocyte count, differential lymphocyte, eosinophyle and MCHC (P>0.05) with lower considerable values than those of the clean station and neutrophilia, monocytosis, lymphopenia and eosinopenia were find in the creeks. Results of the present investigation showed that pollutants have direct correlation with fish blood abnormalities and also indicated that the different in environmental condition of marine ecosystems may cause several changes in the hematological parameters of the studied fish.
