Sunken Tanks Bloom as Coral Reefs
7 Sep
Summary
- Abandoned tanks, trains, and trucks created 72 new artificial reefs.
- Marine survey found 53 fish species, including endangered ones.
- Reefs provide crucial habitat for commercial fish and vulnerable species.
In 2010, Thailand initiated a unique coastal engineering project in the Gulf of Thailand, repurposing 25 retired army tanks, 273 train carriages, and 198 rubbish trucks to create 72 artificial reefs off Narathiwat province. This initiative, supported by the queen, aimed to replenish dwindling fish stocks for local fishermen. The chosen materials provided immediate shelter and surfaces for marine life colonization without the expense of purpose-built structures.
A recent survey explored the marine life established on these submerged remnants, specifically examining a cluster of tanks and a separate group of train wagons. Researchers documented 53 fish species across 21 families, with snappers being the most diverse group. Notably, the tanks attracted larger fish aggregations due to their complex, enclosed structures, while the wagons' wider footprint supported species hovering in the surrounding water.
The artificial reefs are proving successful in their mission, supporting economically vital fish like snappers, a mainstay for commercial and small-scale fisheries. The survey also recorded the presence of the endangered Humphead Parrotfish, indicating the reefs function as a critical shelter for vulnerable species. The Narathiwat artificial reefs now harbor a typical reef fish community, benefiting both local fishing operations and marine conservation efforts.
