Several fish species exhibit antipredator responses when exposed to chemicals which indicate risk of predation. One such substance is the scent of a predator (a kairomone) that may induce defensive responses in a potential prey. In the present study, we show that chemical cues (odour) from predator fish induce antipredator and stress responses in Nile tilapia.

Fish of the same species may perceive these cues and display antipredator behavior. Physiological adjustments may also be needed to deal with this adverse situation.

- The study investigated the effect of sex on aggression among juvenile Nile tilapia, focusing on how it influences intraspecific (within species) interactions.
- The researchers measured several aggression-related factors, including the time it took for confrontations to start and the nature and duration of aggressive exchanges.
- Results indicated that the sex of the fish did not significantly impact their aggressive behavior, suggesting that other factors may be more important in juvenile aggression.
