In a previous investigation, evidence was obtained indicating the presence of erythrocytes in the cytoplasm and germinal vesicle of a teleost fish, Trichogaster fasdatus. Histochemical tests for haemoglobin and related iron compounds have been applied to verify the histological and cytological findings. Haemoglobin (both intact in the erythrocytes and in the crystalline state) and pseudoperoxidase granules have been demonstrated histochemically both in the ooplasm and in the nucleus of immature eggs. Haemosiderins have also been detected and histochemically localized in and around the ooplasmic vacuoles.
