Population Information

There is no information on the current population size and trend of this species.


It is threatened by the construction of hydroelectric dams along Agus River for the generation of electricity for the entire Mindanao. These dams along the Agus River have altered river flows and most probably modified or destroyed habitats of this species. The dam in Saguiaran was constructed in 1975 and has been operational since 1979 (UPLB-DENR 2014, National Power Corporation 2020).
