Two new localities of the endangered fish Systomus martenstyni (Kottelat & Pethiyagoda, 1991) (Teleostei: Cyprinidae) found in Sri Lanka

Abstract

Systomus martenstyni is an endemic and endangered fish of Sri Lanka. This species was earlier known to be restricted to the Amban Ganga River basin. Recently two populations of S. martenstyni were located in two major tributaries of River Mahaweli: Loggal Oya and Badulu Oya in the Uva province of Sri Lanka. These new populations are relatively small and are facing the threat of habitat quality degradation and habitat loss. Effective conservation actions should be undertaken to conserve this endangered fish species.
