May 31, 2026 / Surabaya – “The Brantas River still has the potential to recover and once again become a thriving fish habitat. Recent research has documented 34 fish species in the Surabaya River and 42 fish species in the Brantas River. These findings can serve as a strong foundation for the people of East Java to restore the water quality of both the Brantas and Surabaya Rivers,” said Rulli Mustika Adya, Director of Posko Ijo. Rulli emphasized the need for a large-scale public campaign to introduce native Brantas River fish species to the people of East Java.
