A distribution of β-N-acetylglucosaminidase in the fish blood of various species was investi-gated. The following results have been obtained: 1) β-N-Acetylglucosaminidases, both a neutral form and acidic forms, were demonstrated to have a wide distribution in fish blood of various species. However, the neutral form could not be detected from human and mammalian blood. 2) Carp blood neutral β-N-acetylglucosaminidase was localized in the cytosol of the red blood cells and the acidic forms of the enzyme were in the white blood cells. 3) There existed at least three different forms of β-N-acetylglucosaminidase in carp blood, one neutral form and two acidic forms. 4) With respect to the electrophoretical mobility, behavior of the isoenzymes in DEAE-cellulose chromatography and heat-stability, the neutral form was confirmed to correspond to Hexosamini-dase C, and the acidic forms-1 and -2 may be related to Hexosaminidases B and A, respectively.
