We have obtained information from Huatai Insurance Agency & Consultant Service Ltd. on the summary of the distribution of major fishery farms along the coast of China. For details, please find attached their circular.

1. Affected Waters
   The South Channel and its adjacent waters, from the upper stream boundary of Jiuduansha Precautionary Area and the S1 Light Buoy.

2. Adjustments to Navigation Aids
   Positions of navigation aids (including virtual navigation aids) between S25 and S1 Light Buoys have been adjusted. Other technical parameters (shape, colour, light characteristics, range, etc.) remain unchanged.

3. Adjustments to Channel Axis and Boundary Lines
   The channel axis and boundary lines between Jiuduansha Precautionary Area and S5 Light Buoy have been adjusted southward, while maintaining existing artificial channel dimensions (width, depth). The channel axis between S5 and S1 buoys maintain its original designed alignment.

For safety, please check the latest navigation notices, update charts, strictly comply with VTS instructions, conduct frequent position verification through multiple means, maintain safe speed, and keep sufficient clearance from adjacent ships. Any discrepancies should be reported immediately to the Wusong VTS Center.
