Zebrafish has become a model organism for the study of developmental biology and genetics. Less is, however, known about the behaviour of this cyprinid fish. A zebrafish is exposed to many unfamiliar objects during its lifetime, and the response to these stimuli is critical for an adaptive behaviour. This book presents a master thesis from the University of Bergen in Norway on the behaviour of zebrafish of different origin and background towards a novel object and how the alarm pheromone released by this species upon predator attack modifies the response. In this study we found that laboratory fish inspected the novel object earlier, whereas the presence of a novel object and also alarm substance increased shoaling more in the wild strain. Overall,laboratory zebrafish were bolder than fish from the wild strain. This book provides valuable knowledge on how genetics and experience interact to shape the behaviour towards a potential threat in different strains of zebrafish. It is...
