Core Viewpoint - The cultivation of "brackish water red snapper" in Haikou is transforming perceptions of traditional tilapia, utilizing factory farming methods to enhance flavor and quality, thereby opening pathways to the mid-to-high-end market due to high demand and limited supply [1][2]. Group 1: Project Overview - The project is located in the Meilan District of Haikou, leveraging abundant brackish water resources and innovative agricultural practices to achieve efficient and large-scale cultivation of brackish water red snapper [2]. - The cultivation method involves using brackish water, which is defined as having a salinity between 0.5‰ and 30‰, improving the muscle structure and flavor of the fish [2][5]. Group 2: Production and Market Demand - The red snapper produced at the base is sold at nearly double the price of ordinary freshwater tilapia due to its superior quality, resulting in a market that cannot meet current demand [5]. - The base aims to produce nearly 300,000 pounds of red snapper annually by 2024, establishing itself as a leading product under the "Meilan Good Products" brand and the Hainan snapper brand [7]. Group 3: Technological Innovations - The base has developed a closed-loop farming system to mitigate environmental and climate challenges, incorporating digital monitoring systems for real-time adjustments of water parameters such as temperature and oxygen levels [5][7]. - The project has secured 15 patents related to the cultivation system, water treatment, and environmental control, indicating a strong focus on technological advancement in aquaculture [7]. Group 4: Future Prospects - The establishment of an industrialized cultivation system for brackish water red snapper is expected to promote a unified industry model, which includes standardized seedlings, feed, technology, and insurance, contributing to local agricultural transformation and rural revitalization [8]. - The Haikou government plans to utilize brackish water areas for industrialized circular cultivation of 1,000 tons of red snapper, aiming to create an ecological brand for brackish water products [8].
