Basins of deep-brown-shelled blood cockles are piled high at the seafood stall -- the vendor cracks one open and the red liquid inside is the signature trait of this shellfish. It's a newly discovered item from this round of research, only certified with a geographical indication in 2026, and its farming waters also lie in the coastal shrimp-pond areas beyond the city.
Cross-confirmed by state media and agricultural media as a newly minted 2026 geographical indication
Nhan Dan (the Vietnamese Communist Party's central newspaper), agricultural media, and Ca Mau's official provincial party newspaper cross-confirm that the National Office of Intellectual Property granted the "So Huyet Ca Mau" geographical indication in May 2026, managed by Ca Mau's provincial Department of Science and Technology. This is a newly discovered item found during this round of Ca Mau research, not on the original candidate list -- the blood cockle is plump with a distinctive fresh, briny flavor from its red liquid, a representative shellfish of the coastal shrimp-pond co-farming system.
Honest clarification: the farming zone is in coastal shrimp-pond areas, not within the city; the exact decision number is unconfirmed
It has to be said honestly that the farming zone is concentrated in coastal shrimp-pond co-farming areas across Dam Doi, Cai Nuoc, Phu Tan, Nam Can, and Ngoc Hien districts -- not within Ca Mau City's own territory, where the city mainly functions as a market and restaurant hub. In addition, the exact decision number "193/QD-SHTT" and certificate number "000154" were found only in a single aggregator site's secondhand account, not independently verifiable across two original media reports -- this entry does not adopt that exact decision number, only the cross-confirmed fact that the GI was granted in May 2026.
How to Eat It Like a Local
- Widely served at markets and seafood restaurants in Ca Mau City -- choose tightly closed shells with a heavy, dense feel.
- The traditional way to eat it is quick-fried with garlic or blanched with a dipping sauce, to preserve the fresh, briny sweetness.
- To trace the farming waters, plan a trip to the coastal shrimp ponds around Dam Doi and Cai Nuoc.
An Honest Look at This Cockle's Origins
- The farming zone is concentrated across five coastal districts including Dam Doi and Cai Nuoc -- not within Ca Mau City's own territory.
- The certification's decision number and certificate number were found only in a single secondary source -- this entry does not adopt unconfirmed details.
- This is a newly discovered geographical indication from this round of research, not on the original candidate list -- a result of deeper verification work.
Crack open the shell and the red liquid mingles with sweet, fresh meat sliding across the tongue. This shellfish only recently earned its geographical indication -- proof that the water quality and farming craft of Ca Mau's coastal ponds are still writing a new chapter.
