Oasis Circular No.:2603

Subject: Update on Fishery Farms around Rizhao and Lanshan ports, China

Following our circular 2504 dated 21 July 2025 (copy attached) regarding the fishery farms around the Chinese coast, a new fishery farm has been identified near the ports of Rizhao and Lanshan recently. In so far as we know, more than one vessel passed through this fishery farm in the past few months. At the time of preparing this circular, we understand that the owner of this fishery farm does not hold valid Sea Area Use Certificate and Aquaculture License. MSA does not publish navigation warning in respect of  this new fishery farm.

The new area is marked as “Area 9" in the map below, with the following coordinates:

Recommendations to ships:

1. Please note that the above-mentioned locations of fishery farms are not meant to be exhaustive, accurate or permanent, as they are seasonal and can change from time to time without notice. Therefore, ships are strongly suggested to collect the latest fishery farm information from the local agent in advance, check the updated chart and navigation alerts issued by local authorities, and maintain enhanced lookout when navigating in these areas.

2. It is also strongly recommended that ships navigate in the official recommended channels when accessing these ports. Generally speaking, the chance for fishery farms to exist in the official channels and customary routes is slim, but this possibility cannot be entirely ruled out. Extra caution is still required.

3. If possible, avoid entering into or departing from these ports or anchorages during nighttime or periods of poor visibility.

4. Maintain a proper lookout at all times during navigation, checking AIS and radar while maintaining visual lookout. Many of the fishery farms don’t have AIS or radar reflectors; on the other hand, some of the fishing nets are below the water surface and may be difficult to observe visually.

We hope the above guidance will be of assistance. If there is any query, please feel free to contact us at oasis@oasispandi.com at any time.
