Bullhead catfish (Ictalurus nebulosus) detect the body odors of conspecifics indicative of dominant relationships, and increase territorial aggression toward chemical strangers. Nonspecific diet metabolites as well as specific pheromones are important in chemical mediation of social behavior (Bryant and Atema 1987). Pheromone-mediated social behaviors were also observed in the Nile (Oreochromis niloticus) and the Mozambique tilapia (O. mossambicus ). They use pheromones to establish hierarchies, display elaborate courtship rituals and parental care (mouth-brooding) (Miranda et al. 2005 Barata et al. 2008). In crustaceans, brood pheromone has been associated with maternal behavior in crayfish (Little 1975,1976). Chemical cues in the urine are also important for crustaceans to recognize individuals and to establish dominance hierarchies (Katoh et al. 2008 Skog et al. 2009). A review on crayfish courtship and dominance pheromones can be found in this volume (Breithaupt, Chap. 13).
