Composition of Peripheral Blood Leukocytes of Pink Salmon Oncorhynchus gorbuscha and Chum Salmon O. keta (Salmonidae) during the Marine Life Period

Abstract

In pink salmon Onchorhynchus gorbuscha and chum salmon O. keta lymphocytes predominate among leukocytes in the peripheral blood during the marine period of life. In both species eosinophils are absent, while in pink salmon basophils are also absent. The proportion of segmented neutrophils and the size of lymphocytes, monocytes, and stab neutrophils are lower in chum salmon than in pink salmon.
