China's Waterways Under Siege by Invasive Mollusks

China's aquatic ecosystems are increasingly threatened by the proliferation of invasive mollusks. A recent study reveals that 61 non-native species, including snails and clams, are now established across the nation's rivers, wetlands, and coastal waters.

Many of these introductions occurred after 2000, a surge linked to China's economic and technological expansion, with southern regions experiencing the most severe impacts due to favorable conditions. These invasive species pose a significant risk by outcompeting native mollusks, damaging agriculture, and potentially spreading diseases.

Experts emphasize that prevention and early detection are paramount. Recommendations include enhanced regulatory controls on commercial breeding and imports, alongside improved monitoring systems. Potential interventions mirror global strategies, such as bounty programs and the reintroduction of native predators.
