Abstract The study of behaviour and its ontogenesis can reveal the relationships between an animal and its environment and also can lead humans to better choices concerning the rearing conditions in order to ensure welfare for fish in captivity. The present study was focused in the comparative description of the ontogenesis of behaviour and feeding behaviour of European sea bass reared with two different techniques: intensive and mesocosm. The study of ontogenesis was conducted from the prelarval stages of sea bass to the stage of early juveniles (Chapter 2). Later on, during nursery phase, several acute stressors were applied in order to study their effect on the swimming activity and behaviour in general (Chapter 3). The rearing conditions of fish under captivity can be variable and the levels of these variables can on many occasions affect fish´s welfare. They may lead fish to negative situations and to adopt abnormal behavioural patterns. So, sea bass juveniles were subjected to a series of potentially stressful rearing conditions in order to study the effect of these conditions on the distribution of sea bass and on their behaviour in general. The working goal of the latter study was to evaluate the impact of these parameters on the welfare of sea bass during this ontogenetic stage in captivity (Chapter 4).
