ADVERTISEMENTBut Cruz, in a news conference on Friday, said she was concerned over the impact of mining in Albay, noting that mine waste could contaminate river channels linked to Donsol River. The river, Dioneda said, produces nutrients that sustain krill and planktons, which in turn attract migratory whale sharks to visit Donsol’s waters from March to May. “We are talking here not only of Donsol River but also of other rivers that link to us,” Cruz said. He said his agency was regularly monitoring and testing water quality in these rivers, including Donsol River. It described the whale shark’s population as “decreasing.”The Donsol field office of WWF Philippines recorded 87 whale sharks in the town’s waters since January.
