Abstract

Skin as a protector for internal organs of fish, keeping osmoregulation and indicator in fish health has an important rule. For histomorphometric survey by light microscopic, skin of dorsal fin and caudal peduncle of 20 Barbus grypus with 5mm thickness removed and fixed in bouin solution, then routine procedures of preparation of tissues were followed. Paraffin blocks were cut at 5 to 6 micron, stained with H&E and PAS. In histological examination, skin of this sector is made from epidermis and derm that located on loose connective tissue called hypoderm. In histometric study, skin was divided to different sectors based on cells distribution. The results showed, different sectors of Barbus grypus skin tissue, has some difference, for example lack of taste bud in dorsal, middle and caudal peduncle but has some similarity to the other species as well.
