In the Deduru Oya reservoir of Walpaluwa, Sri Lanka, fishermen are confronting the challenges posed by an invasive snakehead fish species. This fish, which has no natural predators in the area, is rapidly depleting local fish populations. Fishermen have reported a significant decline in traditional catches, while snakehead fish have proliferated since their introduction, likely from released ornamental fish. Despite unsuccessful attempts to control their population through angler competitions, local fishers are adapting by promoting angler tourism and processing snakehead fish into dried products. This shift not only provides alternative income but also helps manage the invasive species. Fishermen like Sujeewa Kariyawasam are capitalizing on the growing demand for dried snakehead, which is gaining popularity despite the fresh fish's limited market appeal.
