Core Viewpoint - The Wenchang Fengjiawan Modern Fishery Industrial Park in Hainan has developed a new model for coastal fishery transformation and upgrading, integrating multi-layer factory aquaculture, centralized deep-sea water extraction, ecological retirement, and seed industry integration [1][2]. Group 1: Industrial Model and Innovations - The park is the largest factory-style "vertical farming" facility in the country, covering an area of 6,408 acres, promoting the transition from traditional fishing to large-scale multi-layer aquaculture [1][2]. - It has achieved the first nationwide implementation of centralized deep-sea water extraction and tail water treatment, ensuring high-quality seawater for aquaculture while minimizing ecological damage [1][2]. - The tail water purification process includes four stages: pre-treatment by farming entities, ecological interception ditches, purification by aquatic organisms, and solidified microbial enhancement, achieving "zero wastewater" discharge [1][2]. Group 2: Policy and Financial Support - The park has introduced the first national operational guidelines for the transfer of state-owned agricultural land and ownership registration for facilities on such land, enhancing land resource allocation and asset revitalization efficiency [2]. - Financial cooperation through "government-bank-guarantee" models, specialized insurance for aquaculture breeding, and incentives for park entry help farmers mitigate risks and reduce burdens [2]. Group 3: Research and Development - The establishment of the Hainan (Wenchang) Fishery Innovation Research Center aims to bridge the gap between technological breakthroughs and industrial applications, involving collaboration among academicians, research institutions, enterprises, cooperatives, and farmers [2]. - Since 2020, the park has launched 40 projects with a total investment of 2.632 billion yuan, increasing land utilization for aquaculture facilities from 50% to over 85% and achieving a survival rate of over 90% for fish and shrimp seedlings [2]. Group 4: Future Development Plans - The park plans to enhance infrastructure and industrial chains, leveraging technology to achieve green and sustainable development in the fishery industry, aiming to create a complete chain of "technology research and development + results transformation + industrial application" [3].
