Plasma melatonin synthesis in juvenile Atlantic salmon Salmo salar decreased with increasing light intensity. Melatonin profiles reflected accurately the photoperiod under which the salmon were maintained. Groups maintained at 12°C showed significantly higher ( P < 0·01) levels of dark phase plasma melatonin compared with the groups maintained at 4°C.
