The factors involved in the development of 'summer lesion syndrome' were studied on 13 salmon farms based in the coastal waters of the west of Ireland. The primary causal factor in the development of the syndrome appeared to be overexposure to solar ultraviolet radiation. The pathology of the condition is described, the predisposing and reinforcing factors are considered and a hypothesis for the cause of the syndrome is proposed.
