Barilius polylepis Regan, 1904 Anabarilius polylepis s a species of freshwater ray-finned fish belonging to the family Xenocyprididae, the East Asian minnows or sharpbellies.

It was once a major commercial fish species,[1] but it has not been confirmed in the lake since the 1970s.

[4] Its decline is attributed to many factors: introduced fish species, decreasing water quality, the loss of macrophytes (partly caused by the introduced grass carp), over-fishing, and the loss of breeding sites due to siltation and blocked access.

[1] Anabarilius polylepis grows to 22.7 cm (8.9 in) standard length.

[3] It lives in the uppermost ten metres of the water column and feeds mainly on aquatic insects, plankton, and plant fragments.
