The aim of this study was to invistigate the impact of hydrocarbons ( car
benzine) on blood parameters (haemogloben content, red blood cells, white blood cells)
of fingerlings of common carp (Cyprinus carpio L., 1758) and Prussian carp
(Carassius auratus gibelio (Bloch,1782). The required fish were brought from the local
fish farms of Marine Science center, University of Basrah, Iraq. Eighty healthy fish of
weight 38٫ ± 0.5 g, , from each of both species were taken, distributed among four
groups of treatment, they included fresh water only (control) and the other three
treatments included 10,20 and 30 ml of benzene each mixed separately with fresh
water in 40 liter volume. Each treatment of two replicates, each replicate of ten fish.
The results showed that Haemoglobin content for common carp were 5, 4.2, 4 and 3 g/
100ml and for Prussian carp were 7.8, 6.5 , 6 and 4.5 g/100ml respectively . Red blood
cells for common carp were 1066000, 1050000, 908000 and 804000 cell / 1mm3 and
for Prussian carp were 2324000, 1826000, 972000 and 842000 cell/ 1mm3. White blood
cells for common carp were 5087, 4762, 3787 and 3300 cell/1mm3 and for Prussian
carp were7813, 7675, 6125 and 5262 cell/1mm3 The three blood parameters of common
carp were lower than ones of Prussian carp. The blood parameters of both species of
fish were decreasing with increasing increment of benzene. |
