Effects of rearing conditions on behavioural responses, social kinetics and physiological parameters in gilthead sea bream Sparus aurata

The results of the behaviour tests; open field test (OFT), neophobia (NEO), object presentation repeat (ORP) showed that the most frequent movements were “escape” and “static” among all of the tests and treatments, while “contact ' and “avoidance' were less frequent. However, few differences were found among treatments, but the large variation among individuals in all of the treatments was remarkable. On the other hand, the results showed that fish reared at a low density exhibit less total movement but are more diversified in their responses to individual behaviour tests and social kinetics.
