Programa de Pós-Graduação em Teoria e Pesquisa do Comportamento.https://repositorio.ufpa.br/handle/2011/9040The zebrafish is widely used in various areas of research as experimental model, dominance and submission phenomenon are present in this species, and relate directly with the aggressive behavior, these can be linked to personality dimensions that can be used to predict and explain the conduct of an individual, creating different profiles of behaviors on certain aspects, these behavioral changes may reflect several factors, among them bodily differences, the availability of food, the pressure of predators, the intraspecific competition, among others. To try to answer whether dominant subjects respond differently in situations involving appetitive and aversive stimuli, was performed a battery of tests involving both previously tested to determine its state of dominance, then were subjected to the following tests as scooling, predator inspection and open field. These results showed that the dominance profile in zebrafish, appears to be related to differences in the behavioral patterns when associated with possible parameter approximation of aversive stimuli (predator) and not aversive stimuli (shoals), which may be related to two large personality, extroversion and neuroticism.Acesso AbertoComportamento animalZebrafishDanio rerio (Peixe)NeuroticismoPersonalidadeAgressãoDominânciaSubmissãoTeseCNPQ::CIENCIAS BIOLOGICAS::ZOOLOGIA::COMPORTAMENTO ANIMAL
