초록

Integumentary structures of the chub mackerel (Scomber japonicus) were examined by light and transmission electron microscopy. The integument of the fish was composed of epidermal and dermal layers. The epidermal thickness is about $20{\mu}m$ in TL 35~40 cm fish. The epidermal layer could be classified into superficial, intermediate, and basal layers by morphology and position of the supporting cells. The epidermal layer also possessed mucous cells, club cells and chloride cells. The area of secretory cells, including mucous and club cells, is about 23% of the epidermal layer. The mucous materials were identified as sulfated glycoprotein, neutral and acid in nature. Club cells had a large central vacuole and rough endoplasmic reticula in the cytoplasm. Chloride cells had numerous tubular mitochondria in the cytoplasm. The dermal layer consists mainly of collagenous fiber, and it contains fibrocytes, pigment cells and cycloid scales.
