Trout were irradiated in a solar light simulator (Full Spectrum
F35 simulator model 1 with scanning system, CSIRO, Australia).
The wavelength and intensity of light was controlled by the use of
different light sources and
filters. Four different irradiation
wavelength ranges were produced: (1) full spectrum sunlight,
(2) ultraviolet B (290–320 nm), (3) ultraviolet A (350–400 nm), (4)
visible blue light (380–480 nm).
