Abstract: Deeper offshore aquaculture plays a crucial role in mitigating the ecological pressures in nearshore waters, expanding the aquaculture industry's development space, and offering high-quality green aquatic products. In Fujian Province, the deeper offshore aquaculture is still in its early stages, and it has introduced the "Fujian Province Pilot Work Plan (2021-2023) For Deepsea Equipment Breeding Project" to research and tackle the technological challenges related to this industry. The plan aims to establish a complete industry chain, enhance the industrial service system, and explore novel fields, mechanisms, and models for deeper offshore aquaculture. This paper is centered around the developmental requirements of the deep-sea aquaculture industry and follows a problem-oriented approach. It presents an industry development service system for deeper offshore aquaculture that consists of three main links and six systems,including infrastructure construction services and financial support services during the pre-production stage, production technology services and industrial supply chain services during the mid-production stage, and brand building services and processing and circulation services during the post-production stage. Moreover, it provides strategies and suggestions for constructing a service system, aiming to establish a comprehensive support system that enables the sustainable development of the deep-sea aquaculture industry.
