As main producing region, the offshore area is the most important marine agriculture district, but the fishery resources have gradually declined recently. Particularly, the biological resource at bottom and near-bottom layers has been excessively utilized, wild fishery resources like Apostichopus japonicus have been nearly exhausted. To the demand of industrial facilities and systems for A. japonicus culture and stock enhancement, the research team where the authors are working studied the biological characteristics of A. japonicus and developed 11 serial new systems for ecologically efficient culture and stock enhancement of sea cucumber A. japonicus. Such new facilities and systems achieved zero breakthroughs of A. japonicus culture and stock enhancement in areas where the culture condition is traditionally unfavorable; besides, such new systems greatly improve the unit-production of coffered A. japonicus culture and also improved the ecological pluralism of A. japonicus culture and stock enhancement. Therefore, these new facilities and systems provide equipment and technical support for sustainable and healthy development of A. japonicus culture and enhancement.
