What is it about?
In this study, we focused on the maintenance of mature stage in adults of P. lividus using artificial diets, and we present a detailed description of the Recirculating Aquaculture System optimization for this species. This experimental protocol permitted them to overcome the summer months during which it is not possible to obtain gametes from organisms belonging to wild population in the Mediterranean.

Why is it important?
The experimental diets were easily eaten by sea urchins and led to a high gonad yield as well as ensuring the provision of good quality gametes. For these reasons, the use of different artificial diets such the ones studied and evaluated in this paper should be considered for application in future sea urchin breeding applications.
Perspectives
This experiment highlights the difference between a wild population and an enhanced breeding system in breeding sea urchin. Its outcomes can represent a valid contribution to the development of an ad-hoc Recirculating Aquaculture System.
