Resumo(s)

Much interest on cuttlefish research during the last years has focused on its introduction as a new species for aquaculture. This is due to this species biological (Barnabe´ 1996) and economical (FAO 2009) aspects which display potential for industrial culture. Recently, Sykes, Domingues, Correia and Andrade (2006) reviewed this potential, the state of the art and future trends of research for the European cuttlefish, Sepia officinalis. In this work, a series of bottlenecks were identified that need to be resolved before the technology acquires sufficient maturity to enable a transition to the industrial scale. Control of reproduction in captivity is essential for the sustainability of commercial aquaculture production. This factor was identified as a major bottleneck in cuttlefish culture due to several biological aspects of the species, such as semelparity, low fecundity and fertility and eventually inbreeding (Sykes, Domingues & Andrade 2006).
