Laguna de Bae is the largest fresh water lake of all of South East Asia, 12 leagues wide (66 kilometers) and very deep. Centuries past, fishing from this lake was productive, for subsistence fisherfolks, but not anymore due to over-fishing, lake pollution along its shores, and invasive species which the natives call janitor fish (because they would eat any and all varieties of native fish in this lake). The knifefish, known scientifically as Chitala ornate, is the invasive species with its ability to prey on native and economically important marine edibles.
