Barbodes sirang

Declining

Overview

Barbodes sirang, known locally as the sirang, is a possibly extinct species of cyprinid fish endemic to Lake Lanao in Mindanao, the Philippines. This species can reach a length of 8.6 centimetres (3.4 in) TL.

Barbodes sirang faces severe threats from habitat degradation in its limited range within the Lake Lanao basin of Mindanao, Philippines. The species has experienced dramatic population declines due to the introduction of non-native fish species that compete for resources and prey on juveniles. Water quality deterioration from agricultural runoff and urban development has further compromised the lake's ecosystem, while overfishing has reduced breeding populations to critically low levels.
