The place is known as Tibang, on the coast of Banda Aceh in northwest Sumatra. What is seen in these pictures as a river or canal and pools is in fact part of a lagoon. On the north side, after being blocked by land, is the Aceh sea. Water in that and other canals goes in and out of the sea. It then also mixes with fresh water that comes from land. The water in this zone is brackish, and is used for the cultivation of fish that live in brackish water.
But if you look at the surface of the water, you can see wooden and bamboo stakes, as well as car tires. Is it waste?
Turns out it wasn't waste! It was deliberately made there for oyster farming. The oysters will naturally grow on the wooden and bamboo stakes, and in the shallow water substrate. The stakes have their respective owners. The owners would harvest the oysters from time to time.
So, the lagoon area, thus, becomes a source of delicious food, as well as a source of sustenance for residents in the area. I took some photos from there to show nature and a coastal life in the tropics.
Those are photos I took of a bridge over a canal in the lagoon.
I then descended the bridge, and went along the canal's bank to take a closer look at the oyster cultivation.
The bamboos and car tires are used for oysters to grow there.
I moved to another lagoon area after crossing the estuary that separated this lagoon from the previous one. And I shot some pictures from this second place.
