Batang Toru Hydro Electric Power Plant releases Mahseer fish into the Aek Uluala Namenek River.
The Batang Toru Hydro Electric Power Plant Project, constructed by POWERCHINA, recently collaborated with the South Tapanuli government's Fisheries Department and the international environmental organization WEK V Batang Toru to release 1,000 artificially bred juvenile Mahseer fish into the Aek Uluala Namenek River.
This marks the third phase of their initiative to bolster conservation efforts for this rare species.
The Mahseer, a unique species indigenous to the rivers of Southeast Asia, thrives in the tropical rainforest streams of Borneo and Sumatra. Known for growing up to 1.2 meters in length, their migratory patterns serve as a critical biological indicator of river health.
However, overfishing has led to their decline, with a report from the Indonesian environmental group Forum Konservasi Leuser revealing the absence of adult Mahseer in five northern Sumatra rivers over the last decade, highlighting an urgent need for intervention.
Located near the Mahseer's migratory paths, the plant has prioritized an "ecology-first" philosophy since its inception. The project team has developed comprehensive conservation plans for endangered species like the Mahseer, orangutans, and hornbills.
International wildlife conservation experts performed extensive biodiversity surveys and assessments. The team has also conducted biodiversity education seminars for employees and participated in wildlife rescue initiatives, implementing proactive measures to maintain the balance of the aquatic ecosystem and protect biodiversity.
Since June 20, 2024, the team has embarked on a long-term conservation plan for the Mahseer, which includes regular releases of juvenile fish. This sustainable "green development" approach has garnered widespread acclaim from the South Tapanuli government, fisheries departments, environmental agencies, and local communities.
This initiative enhances the green image of hydropower and fosters a deeper understanding of hydropower projects among local communities. It stands as a testament to POWERCHINA's commitment to global biodiversity governance, aligning with international treaties such as the Convention on Biological Diversity, the Ramsar Convention, and the Convention on International Trade in Endangered Species of Wild Fauna and Flora.
