is a relatively new marine species for aquaculture. Its high market value and declining wild stocks worldwide prompted the interest of the aquaculture industry. The general rearing systems rely on technology developed for the related sparid Gilthead seabream as well as Seabass. However, some aspects of its biology in the wild and under farming conditions remain poorly understood, namely aggregation patterns and aggressive behaviour. Furthermore, it is a very sensitive species that presents very high mortality and malformation rates, and some attributes of its life history cannot be fully met in aquaculture, such as home and depth ranges. Standard slaughter procedures are also sub-optimal, despite the fact that there are humane methods developed for related species.
