The studies on the capacities of immune responses of lymphocytes in peripheral blood and immune organs of Grass Carp (Ctenpharyngoden idellus Cuvier et Valencinnes) to PHA and SPA with incorporation of 〓H-TdR and active reaction of Acid α-Naphthyl Acetate Esterase indicated that there were T and B lymphocytes in peripheral blood of grass carp, but only T lymphocyte and no B lymphocyte in the thymus of grass carp. It was justified that the T lymphocytes in peripheral blood was originated from the thymus, and B lymphocyte could be from the spleen and anterior kidney of grass carp.
