The Aquaculture Research Group (GIA) created the line “Cephalopod culture technology” in 2001, following the 1st national project on the aquaculture of this species.  It has subsequently participated in other two national projects, adding more than 10 years of experience in the rearing of common Octopus Octopus vulgaris. At paralarvae level, several trials were designed, in order to test the potential beneficial effect of: different light intensities, the addition of crab zoeas as complement of Artemia, several enrichment commercial and experimental products for Artemia and different rearing systems (volume, shape and color of the tanks). Regarding the grow-out phase, several natural fresh diets (crabs) and fish by-products (discarded by local fisheries and fish farms) were tested. In addition, experimental compound diets were also elaborated, including several wet and dry raw materials. These studies were carried out in tanks and in sea cages, testing for the 1st time a pilot scale a benthic cage, specifically design for this species.
