Impact of black grape byproducts on blood picture in common carp (Cyprinus carpio L.)‎

Abstract EN

This experiment was conducted for 70 days on 165 common carp Cyprinus carpio fingerlings which were brought from local fish farms located in Daqooq, Haftaghar, Al-Tameem province.

Fishes were distributed among experimental tanks with mean initial weight of 24.09 gm.

They were pre-acclimated to laboratory conditions for 21 days prior to the feeding trials.

The experiment was conducted by using 15 plastic tanks (100 L) representing five treatments with three replicates.

Each tank 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 group was significantly higher than other treatments.

Hemoglobin of fishes in groups 2.5 and 10 gm/ kg diet was significantly different from other treatments.

Mean corpuscular hemoglobin (MCH) values for 0.0, 5.0 and 10 gm / kg groups were significantly different, so mean corpuscular volume (MCV) values showed significant differences resulted from 0.0, 5.0, 7.5 and 10 gm/ kg diet compared to 2.5 gm/ kg diet group.

The white 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 from control.

Lymphocyte percentages were significantly different in all treatments compared to 10 gm / kg diet group.

The Monocytes were significantly different in 2.5, 7.5 and 10 gm / kg groups-
