Abstract

Integumentary structure of the amberjack, Seriola dumerili, was examined by light and transmission electron microscopy. Integument of the amberjack consists of epidermal and dermal layers. The epidermal thickness is about $28.32{\mu}m$. The epidermal layer could be classified into superficial, intermediate, and basal layers by morphology and position of the supporting cells. Secretory cells of the epidermal layer were classified into mucous cells and club cells in the amberjack. Mucous cells contained acidic mucous and were alcian-blue positive with AB-PAS (pH 2.5) reaction. The club cells contained well-developed rough endoplasmic reticula and large central vacuole. Also, filament-rich cells were identified in the epidermal layer. The dermal layer consists mainly of collagenous fiber, and it contains fibrocytes and pigment cells. The cytoplasm of fibrocyte had a well-developed rough endoplasmic reticulum. The pigment cells contained electron-dense melanin granules.
