Abstract
Many fishes use sex hormones (steroids and prostaglandins) as pheromones (external chemical cues). Such hormonal pheromones are best understood in carps such as the goldfish, in which ovulating females release steroid and prostaglandin odorants that trigger ovulation in additional females and complex responses in males that facilitate sperm competition. The discovery of hormonal pheromones fundamentally changes our concept of fish reproduction by illustrating how endogenous hormonal signals that originally evolved to coordinate reproductive processes within the individual have been coopted as exogenous odorants that synchronize reproduction among conspecifics.
