Percentage of Leukocytes in Peripheral Blood, Head Kidney, and Spleen of the Abramis brama (Cyprinidae) Bream of the Upper Volga Reservoirs.

The results of a comparative study of the leukocyte formula of the bream Abramis brama, living in the Ivankovo, Uglich and Rybinsk reservoirs, have been presented. Significant differences in the content of band neutrophils and eosinophils in the peripheral blood, pronephros and spleen between individuals of all studied reservoirs were recorded. The highest leukocyte abundance index was observed in bream from the Uglich Reservoir. [ABSTRACT FROM AUTHOR]
