Pollution bioindicator of Musa creek based on study of some blood parameters of Liza abu in two winter and summer seasons

This study was conducted to investigate some blood factors of Liza abu in two winter and summer seasons in Musa creek at Petrochemi, Ghanam, Zangi, Douragh, Patil and Sajafi as a control station. After catching fish by trawling, ?? pieces of fish were removed almost equally. In each turn, fish samples were anesthetized with ?ml of clove extract per liter of water and blood samples were taken immediately from the caudal vein using a heparined syringe. Then, the parameters were measured by conventional and usual laboratory methods and the mean of them was determined in two seasons at each station and analyzed statistically. Results showed that the number of white and red blood cells, hematocrit percentage, hemoglobin amount, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) in more pollution stations such as Petrochemi and Ghannam were significantly reduced compared to the control station (P
