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).
