During the first State of the Nation Address (SONA) of the President two years ago, before the closure and rehabilitation of Boracay, and now the order to clean up Manila Bay, President Duterte took a similar step to address pollution of the waters of Laguna de Bay. He ordered the dismantling of the fish pens/cages in the lake. As reported by the press, the premise was fish farming (aquaculture) was fouling the lake, and unduly depriving poor fisherfolk of fishing grounds.
