Abstract: 

Gills of catfish Silurus glanis (300g weight) of Mahabad Dam were examined for structural attributes in 2004. Immediately after catch, gills were removed and placed in Bouin and Glutaraldehyde for structural and microscopic examinations. For classical histological assessment, samples were stained with Hematoxylin and Eosin and examined under light microscope. For electron microscopy, cuts 90 nanometers each were prepared and stainted with Uranyl Acetate and Lead Citrate, covered with silver, examined and photographed.
We found the gill cells being composed of ionocyte
a,b, accessory, mucous, pillar and mosaiccells. The ionocytes were located at the base of the gill rakers and intra-raker spaces. Thesestructural attributes of ionocyte cells demonstrate their active role in osmotic regulation of catfish.
