Description
Summary:Agonistic behavior of decapod crustaceans occurs in the wild, is highly stereotypical, and is readily quantifiable. Here we explore the persistence of dominance relationships in socially naive juvenile American lobsters (Homarus americanus) by examining the time frame over which behavior changes as a result of previous fight experience. We paired opponents for three fights: initial; 1 hour later; and after 1, 4, or 7 days of separation. As reported in previous studies, the mean duration of encounters decreased when a dominance relationship had been established. After 1 day of separation, both duration and intensity of encounters remained significantly lower compared to the initial fight. At 4 days of separation, the duration of encounters was still significantly' reduced, indicating that the behavior of socially naive juvenile lobsters is influenced by fight experience for at least 4 days.
