Ultrastructural Observations on the Leucocytes of Ophicephalus striatus Bloch and Clarias batrachus Linnaeus.

Abstract

Four types of leucocytes, namely lymphocytes, neutrophils, eosinophils and macrophages, were found in the gill lamellae and kidney of Clarias batrachus Linnaeus and Ophicephalus striatus Bloch. The fine structure of these cells was described. The differences in electron micrograph appearances among the leucocytes in the same fish species and the resemblance of the same kind of leucocytes in the different fish species were indicated.
