The Andamanese tribe is distinctively characterized by its oceanic knowledge and sustainable fishing and hunting practices. The traditional fishing tools of the Andamanese include the Kud, which is a fishing net made entirely from natural forest materials like creepers and plant fibre. The Kud is a circular frame made from pliable creepers, carefully bent, and tied into a strong ring. The fishing net, made from fine plant fibers derived from the forest, is attached to the frame. The plant fibers are famous for their strength, flexibility, and resistance to damage by water. To further secure the net to the frame, creeper stems are tied to the joint; this not only immensely strengthens the joint but also prevents it from giving away when it is underwater or when weighted down by a catch.
In shallow coastal waters, lagoons, and tidal creeks, the Kud is predominantly used, specially designed to be user-friendly and portable. It is larger and with a wider mesh to catch small- and medium-sized fish and crustaceans. The beauty in putting together such an instrument lies within the members' skills and ecological knowledge of gathering the materials and assembling the Kud. The Kud reflects the harmonious relationship that Andamanese have with nature, indicating that indigenous people have sustainably managed natural resources for a long time. This practice has established a bridge between sustainable resource management and development of traditional tools and procedures adapted to a specific environment.
