Threats [top]

Major Threat(s):	In the last ten years, illegal gold mining in the Kapuas River basin has increased dramatically, and as a result, the Kapuas River is experiencing environmental problems due to poor mining practices. One of these problems is the increase of mercury pollution in the Kapuas River. So far, efforts to prevent water pollution and environmental destruction in the basin have failed, and the damage continues (Adijaya and Yamashita 2004). In addition, freshwater habitats in Kalimantan are threatened by deforestation, conversion of land to agriculture, overfishing, the introduction of exotics and the aquaculture industry (WWF 2001).
