Sex pheromones play a major important role in many teleosts. In females, pheromone production increases at the time of ovulation, in conjunction with onset of sexual behavior, whereas in males, pheromone production may be extended during the breeding season (95). 

Some data suggest that female of Ictalurus punctata, Petromyzon marinus, Salmo gairdineri, Blennius pavo, Gobius jozo and Brachdanio rerio are attracted to the odor of mature conspecific males (90, 94).
