'No-mucus skin disease' of rainbow trout, Oncorhynchus mykiss (Walbaum): a case report
JOURNAL OF FISH DISEASES(1995)
摘要
A skin disease of intensively reared salmonids in Ontario hatcheries, known to the farmers as 'no-mucus skin disease', is reported for the first time. It was characterized by erosive and ulcerative lesions found mainly on the flanks of fingerlings, which resulted in exposure of the tips of the scales. Associated with these lesions were colonies of bacteria seen in the SEM to be clustered round the mucous cell pores and under-running the margins of epithelial cells. The cause of this condition is unknown, although the response of fish to formalin treatment, and the presence of bacilli seen in skin scrapings and in the SEM, suggest that bacteria are responsible.
