Impact of Black Grape byproducts on Blood Picture in Common Carp (Cyprinus carpio L.)

This experiment was conducted for 70 days on 165 common carp Cyprinuscarpio fingerlings which were brought from local fish farms located in Daqooq,Haftaghar, Al-Tameem province. Fishes were distributed among experimental tankswith mean initial weight of 24.09 gm. They were pre-acclimated to laboratoryconditions for 21 days prior to the feeding trials. The experiment was conducted byusing 15 plastic tanks (100 L) representing five treatments with three replicates. Eachtank was stocked with 11 fishes. Treatments included 0, 2.5, 5.0, 7.5 or 10 gm grape byproduct/kg diet. The result showed that red blood cell (RBC) data of the control groupwas significantly higher than other treatments. Hemoglobin of fishes in groups 2.5 and10 gm/ kg diet was significantly different from other treatments. Mean corpuscularhemoglobin (MCH) values for 0.0, 5.0 and 10 gm/kg groups were significantlydifferent, so mean corpuscular volume (MCV) values showed significant differencesresulted from 0.0, 5.0, 7.5 and 10 gm/ kg diet compared to 2.5 gm/ kg diet group. Thewhite blood cells (WBC) were significantly different in 2.5, 5.0 and 7.5 gm/ kg diet.Granulocyte percentages obtained in all treatments were significantly different fromcontrol. Lymphocyte percentages were significantly different in all treatments comparedto 10 gm/ kg diet group. The Monocytes were significantly different in 2.5, 7.5 and 10gm/ kg groups.
