Feng and Bass reveal a circadian rhythm in fish mating calls. These nocturnal calls are suppressed by light but rescued by melatonin, the major vertebrate timekeeping hormone. Neural distribution of melatonin receptor supports melatonin action in neural circuits controlling vocalization and in neuroendocrine centers controlling reproduction.
