The use of cage lighting to reduce plasma melatonin in Atlantic salmon ( Salmo salar ) and its effects on the inhibition of grilsing
The effects of additional night time illumination on circulating plasma melatonin levels and maturation were studied in Atlantic salmon maintained in sea cages under commercial conditions. Salmon subjected to additional night-time lighting from November to July had significantly lower dark phase mel...
