In Malaysia, invasive fish species like the suckermouth catfish are threatening the nation’s rivers and native aquatic life. Originally introduced for aquariums, the hardy suckermouth has proliferated in polluted rivers, outcompeting local species, spreading disease, and causing environmental damage such as riverbank erosion. The Klang Valley, along with many other waterways, is now overrun by these aggressive invaders. Alarmed, Mohamad Haziq founded a volunteer group during the Covid lockdowns to combat the ecological threat. Dubbed Malaysia’s ‘foreign fish hunter squad’, the group now boasts over 1,000 members and meets weekly to catch and remove invasive fish. While suckermouths are largely considered undesirable, their eggs are used for bait, and researchers are exploring potential uses for the fish - including biochar, leather, fertiliser, and pharmaceutical collagen. Despite acknowledging the fight may never be fully won, the group remains committed to raising awareness and protecting Malaysia’s fragile river ecosystems, one net at a time.
