Light Pollution Suppresses Melatonin Production in Perch

Light Pollution Suppresses Melatonin Production in Perch Melatonin controls the body clock – high melatonin levels make us feel tired in the evening. However, the hormone also plays an important role in animals' biological rhythms. Artificial light at night – light pollution – can suppress the production of melatonin in fish, even at very low light intensities, a finding established by researchers from IGB. Read more »
