A histological and ultrastructural study of the skin of rainbow trout (Oncorhynchus mykiss) alevins exposed to different levels of ultraviolet B radiation.

The current study was conducted to evaluate the effects of UV-B radiation on survival rate and histopathological changes in the skin structure and ultrastructure in rainbow trout (Oncorhynchus mykiss) alevins. In laboratory dark conditions, newly hatched rainbow trout alevins were exposed to two different doses of UV-B radiation (high dose: HD: 94.83 μW cm(-2)) and (low dose: LD: 68.
