Aquaculture of Octopus species: present status, problems and perspectives

The aquaculture of Octopus species is currently an active field of research around the world, but economic viability is not yet achieved. Here, the current state of knowledge with respect to Octopus water quality and nutritional requirements, reproduction, juvenile and adult stages in culture systems, which comes mainly from just one species, Octopus vulgaris (Cuvier, 1797), is reviewed. Some critical considerations are addressed and new research lines are proposed.
