China's first large unmanned autonomous feeding vessel, "Yuepo Yuyang 10001", started its trial operations at the temporary anchorage of Leizhou Bay Marine Ranch in Zhanjiang in South China’s Guangdong province on June 8. It is set to be used for deep-sea aquaculture operations.

This vessel marks a significant advancement in China's second-generation marine ranching technology, addressing the gap in deep-sea intelligent aquaculture equipment. It provides crucial support for Zhanjiang's efforts to establish a national-level modern marine ranching demonstration zone.

Developed as a core project by the Zhanjiang Bay Laboratory, the vessel measures 29.4 meters in length and 6.2 meters in width, featuring an all-electric propulsion system. It integrates advanced modules for autonomous navigation, remote control, precise feeding, and real-time monitoring. It combines three operational modes - manned supervision, remote intervention, and autonomous operation, enabling fully automated deep-sea feeding.

On May 19, the vessel reached the Leizhou Bay Marine Ranch under the escort of Zhanjiang maritime authorities. It is currently in the commissioning, inspection, and certification phase, with plans for imminent operation. Once operational, the vessel is expected to significantly enhance farming efficiency, reduce operational costs, and facilitate the transformation of Zhanjiang's marine farming from traditional manual methods to intelligent, precise, and eco-friendly practices.

Zhanjiang maritime authorities pledged ongoing support to ensure the smooth operation of the vessel, thereby enhancing Zhanjiang's modern marine ranching capabilities and supporting the upgrade of Guangdong's deep-sea aquaculture industry.
