Located approximately 100 kilometers northeast of Phan Thiet City and nine kilometers off the coast of Phuoc The Commune, Tuy Phong District, Binh Thuan Province, Cau Islet covers just 140 hectares of the 12,500-hectare Cau Islet Maritime Reserve.
Cau Islet and its surrounding body of water are home to a tropical maritime ecosystem, used as a popular breeding ground for a variety of sea turtle species and known for its diverse fish and bivalve populations.
The coral carpet on the islet’s seabed flourishes under the Cau Islet Coral Conservation Program. A seabed survey on Cau Islet Maritime Reserve carried out on May 10, 2016 by Binh Thuan Province's aquatic authority showed that the seabed was in good recovery.
Below are a series of photos by Do Huu Tuan showing how the islet has been reserved.
These photos were one of the entries to Tuoi Tre (Youth) newspaper's year-long competition themed “Vietnam – Country – People" concluding in October last year.
The entry won the competition's third prize.
