Garbage appears quite a lot in the areas of Hon Ga Choi, Me Cung area... - places where there are always many tourist boats that take tourists for day trips and overnight stays in the bay. There are all kinds of garbage but mainly small foam buoys.
According to crew members on cruise ships, this could be because people raise oysters but when harvesting, they do not drag them to shore but harvest them right at sea and let them drift there.
There are all kinds of trash but mainly small foam buoys.
In addition, these are also the remaining pieces of broken buoys from a huge amount of foam buoys that have been released for many months on the sea surface from Ha Long to Cam Pha, Van Don due to the process of replacing foam buoys of aquaculture rafts and handling illegal aquaculture cages in Ha Long Bay, Bai Tu Long.
Although localities and authorities have basically recovered the amount of foam buoys drifting at sea, a small amount is still stuck in rocky crevices, mangrove forests, and occasionally when there is heavy rain or high tide, it will drift back out to sea.
Processing this type of waste will take a lot of time and effort.
During the "crisis" of foam buoys in Ha Long and Bai Tu Long bays in April-May 2023, there was a week when Ha Long city alone collected about 100,000 foam buoys; not to mention Cam Pha city and Van Don district.
