POLICY WIRE — Kuala Lumpur, Malaysia — A fish resembling a red-bellied piranha has been caught twice in a reservoir in central Malaysia, triggering public concern and calls for stricter control over non-native species.

The first specimen was captured at Klau Dam in Raub, Pahang, on 26 August by a local resident using a cast net. Footage of the catch spread rapidly via WhatsApp, sparking fears of potential attacks on children and worries that a dangerous predator could spread through local waterways. The fish died before experts could examine it.

A second similar fish was reportedly caught on 19 September beneath a bridge on the Klau River, though officials have not confirmed the sighting. Authorities say they cannot definitively identify the species without a physical sample. Experts warn that even if the fish can survive in Malaysia’s warm waters, establishing a population would require evidence like juveniles or repeated catches over time.
