Hau Dat Mui

Cage-raised oyster farming began as a trial at Dat Mui in 2005 -- the core production area is around Dat Mui in Ngoc Hien district, not within Ca Mau City's own territory

A restaurant serves up a plate of shucked oysters, plump and rich -- the owner calls them "Dat Mui oysters." Dat Mui is the landmark at Vietnam's southernmost point, and cage farmers have raised these oysters relying on its alluvial silt and abundant plankton -- though that cage-farming water, too, lies beyond Ca Mau City's own territory.

Cross-confirmed by the tourism department, mainstream news, and fisheries-industry media as a specialty tied to a landmark

Ca Mau's official tourism website, Tien Phong (the Ho Chi Minh Communist Youth Union's official newspaper), and fisheries-industry media tepbac.com cross-confirm that Dat Mui residents began a cage-oyster-farming trial in 2005, forming a 25-household cooperative in 2007. Today there are over 35 cages, producing roughly 250-300 tons a year. The oysters rely on Dat Mui's alluvial silt and abundant plankton, growing plump and rich -- a fisheries specialty tied to the landmark of "Vietnam's southernmost point."

Honest clarification: the core production area is Dat Mui in Ngoc Hien district, not within the city; judged not a duplicate of Vung Tau's oyster porridge

It has to be said honestly that the core production area is not within Ca Mau City's own territory but rather the Dat Mui area under Ngoc Hien district -- restaurants in the city mainly serve it, but the city's own territory isn't the farming water. This entry also honestly discloses a cross-check against an existing city in this guide: Vung Tau already features "Chao hau Long Son" (Long Son oyster porridge), but the dish form (porridge versus raw or char-grilled), region (southeastern coast versus the Mekong Delta's southernmost tip), and farming ecology all differ -- judged not a duplicate. The annual yield figure of "250-300 tons" comes from industry and official tourism-website reporting, not a formal census statistic, and this entry honestly notes the nature of that data.
