Polyprion americanus, is a marine, bathydemersal, and oceanodromous fish belonging to the family Polyprionidae, having a worldwide distribution and living in deep waters. Wreckfish is considered one of the most interesting new species for aquaculture diversification, due to its fast growth, late reproductive maturation, high market price and limited fisheries landings. However, the deep-water living behaviour, the difficulty in acquiring wild fish for initial broodstock formation, the lack of reproduction control in captivity and the lack of any larval rearing protocols are serious bottlenecks. Further research is needed on both natural behaviour and physiological effects of farming practices in order to develop specific rearing conditions and provide recommendations for improving fish welfare.
