海水养殖是对国家食物安全、国民经济和贸易平衡做出重要贡献的产业。为实现新时期我国海水养殖业的可持续发展，急需拓展养殖新空间，实施深远海养殖战略。深远海海水养殖是一个综合体系，包含适养物种、养殖技术、养殖装备、能源供给、海陆接力物流、水产品加工和减灾防灾策略等要素。本文基于开拓海水养殖新空间的战略构想，提出了我国发展深远海海水养殖体系的战略任务，包括：适宜品种繁育和高效养殖技术体系；以深远海养殖平台为核心的新型海洋渔业生产模式；深远海海水养殖能源保障系统；海洋水产品智能化物流系统网络平台。基于此，还提出了相关政策建议。

Mariculture industry, makes great contribution to national food security, economy and trade balance. To realize sustainable development of mariculture in China in the new period, it is urgent to exploit new space and develop offshore aquaculture strategy. Offshore aquaculture is an integrated system including suitable species, culture techniques, culture equipments, energy supply, sea-land relay logistics, aquatic products processing, and strategies of disaster prevention and reduction. On the basis of a strategic concept of the new space for mariculture in China, the present study puts forward strategic missions on the development of offshore mariculture. The missions include building a suitable species breeding and efficient farming technology system, constructing a new type of marine fisheries production mode with the core of offshore aquaculture platform, building an energy security system, and constructing an intelligent mariculture products logistics network. Based on these strategies, relevant policy suggestions are also suggested.
