          Abstract

          Glycoproteins (GPs) were visualised histochemically in the secretory cells - the mucous goblet cells (the type A and the type B), the serous goblet cells, the club cells and the epithelial cells in the gill epithelium of Rita rita. The type A mucous goblet cells, the type B mucous goblet cells and the epithelial cells elaborate GPs with oxidizable vicinal diols and GPs with sialic acid residue without O-acyl substitution. In addition, GPs with O-sulphate esters are elaborated by the type A and GPs with O-acyl sugars by the type B mucous goblet cells. GPs are absent in the serous goblet cells and are with oxidizable vicinal diols in low moieties in the club cells. The analysis of the results elucidates interesting differences in the composition and concentration of GPs in the mucus elaborated by the epithelium of the gill arches and the gill rakers; and the gill filaments and the secondary lamellae indicating the potential importance of the glycoproteins at these locations. GPs elaborated on the surfaces of the gill arches and the gill rakers could be associated to assist in feeding activities and on the surfaces of the gill filaments and the secondary lamellae in the respiratory activity.
