Sri Lanka is endowed with a rich network of rivers that dissects the island into 103 river basins. Mahaweli River, 332 km long, is the largest of these basins, covering 10,327 km2, approximately one-sixth of the island’s land area. Mahaweli River passes through three bioclimatic zones and therefore comprises a cross-section of almost all the natural ecosystems present in Sri Lanka other than tropical rainforest. Further, the river basin is inhabited by a diverse species assemblage including a number of endemic plants, fish, frogs, reptiles and mammals that are restricted to this river basin. Martenstyn’s Barb Systomus martenstyni (Sinhala name: Dumbara Pethia) is one such endemic freshwater fish species restricted to the Mahaweli Basin.
