The incorporation of new marine species in aquaculture is esencial to development of this activity. The recent advances on the establishment oftechniques to produce red porgy (Pagrus pagrus), allow to consider it as a strong potencialto aquaculture, being predictable its implement in the Canary Archipel. Neverthe!ess, so far it is not posible to produce it comercially, due to difficulties in assuring a continual supply of larvae and fry. Knowing this, it is crucialto continue studying the production techniques oflarvae and the feeding system during this periodo For this, the aim of tbe work is to optimize production
