Abstract :

The present investigation aimed to study the histological structure of skin and its pathological changes in goldfish (Carassius auratus) without consideration to responsible the agent. 20 goldfish with clinical signs of skin diseases were collected from aquariums in different part of the city. Skin tissue sections with five-micrometer thickness were prepared to examine by light microscope. The results showed that goldfish normal skin consist of layers including epidermis, dermis and hypodermis. Mucous cells, alarm cells and epithelial cells were observed in epidermis. Damaged skins showed pathological changes such as hyperplasia of epidermal cells, decrease of epidermal cell layers, leukocyte infiltration and epidermal destruction, hypertrophy of epidermal squamous cells, epidermal desquamination, intercellular edema, hemorrhage and transformation of red blood cells.
