The Kapuas River (or Kapoeas River) is a river in the Indonesian part of Borneo island, at the geographic center of Maritime Southeast Asia. At 1.143 km (710mi) in length, it is the longest river in the island of Borneo and the longest river in Indonesia and one of the world’s longest island rivers. It originates in the Müller mountain range at the center of the island and flows west into the South China Sea creating an extended marshy delta. The delta is located west-southwest of Pontianak, the capital of the West Kalimantan province.
This Kapuas River should be distinguished from another Kapuas River, which starts on the other side of the same mountain range in central Borneo but flows to the south, merging with the Barito River and discharging into the Java Sea.
The area whose biotope I sampled is a small stream in the town of Mandor in West Kalimantan. It is a region where species such as Betta mandor and Betta brownorum are endemic.
