One month ago, the resonant sound of a ship's whistle echoed across Maxie Bay as Zhanjiang Bay 1, the world's first floating, dynamically positioned cage-type aquaculture vessel, was officially delivered in Zhanjiang. The vessel is slated to head toward waters roughly 30 nautical miles off Naozhou Island to begin routine comprehensive offshore aquaculture testing and research.

In July 2025, Guangdong's largest intelligent aquaculture platform, Hengyi No. 1, which has been in operation for a full year, achieved its first major harvest. This offshore "sea fortress" consists of six independent large-scale breeding cages with depths reaching up to 25 meters.

Integrating a novel configuration of a central platform with ship-shaped hulls at both ends and the cutting-edge "cruising aquaculture" mode, this "steel giant whale" has truly realized the capability of migrating alongside the fish. It can proactively select sea areas with optimal water temperature, currents, and climatic conditions, avoid severe weather, and allow fish inside to grow healthily in a quasi-natural environment.

During harvest seasons, fishermen steer vessels alongside the deep-sea cages and deploy mechanical booms to lower nets. As the large nets are gradually tightened, fish surge to the surface, and more than 50 tonnes of fish are hauled aboard. These freshly caught fish are then transported via cold-chain logistics to consumers nationwide.

So far, Guangdong has deployed 7,498 gravity-type deep-water net cages, ranking first in the country and representing a 40% increase from the end of 2022. Meanwhile, truss-type net cages have expanded to 18, a fivefold increase over the same period. In 2024, the volume of deep-water cage aquaculture reached 16.82 million cubic meters, nearly five times the volume at the end of the 13th Five-Year Plan period (2016-2020). Key industry technologies and equipment, such as unmanned intelligent feeding vessels, underwater robots, and feeding drones, have also started field testing.

广东智能养殖平台助力海上丰收

一个月前，麻斜海湾传来嘹亮汽笛声，全球首创漂浮式动力定位网箱型工船“湛江湾1号”在湛江正式交付，将驶往硇洲岛外约30海里海域，开展常态化的海上养殖综合试验研究。

今年7月，投运已满一年的广东规模最大智能养殖平台“恒燚1号”，迎来首批丰收。这个“海上堡垒”有6个独立大型网格，养殖水深可达25米。

中间平台、两端船型的全新构型，叠加先进的“游弋式养殖”模式，这条“钢铁巨鲸”真正实现了带鱼迁徙的能力。它可主动选择水温、洋流、气候等最适合的海域，躲避极端天气，让舱内鱼群在仿自然环境中健康生长。

每逢收获季，渔民便会驾驶渔船，用机械吊臂朝深海网箱下网。随着大网慢慢收紧，鱼群浮出水面，涌动不息，十几万斤的鱼被捕捞上岸，并通过冷链物流将新鲜美味送达千家万户。

截至目前，广东累计建成重力式深水网箱7498个，数量居全国第一，比2022年底增加40%；累计建造桁架类网箱18个，比2022年底增加5倍。2024年深水网箱养殖水体达1682万立方米，比“十三五”末增长近5倍。无人智能养殖投喂船、水下机器人、投喂无人机等行业关键技术设备也已投入实测。
