Abstract Diet manipulation, an habituation test, and chemical analysis of urinary free amino acids were used to demonstrate that bullhead catfish (Ictalurus nebulosus) naturally detect the body odors of conspecifics and respond to them in a predictable fashion. These signals are used in dominance and territorial relationships and lead to increased aggression toward chemical “strangers.” The results support the general notion that nonspecific metabolites, as well as specific pheromones, are important in chemical mediation of social behavior.
