During Invasive Species Week, Natural Resources Wales warns of Chinese mitten crab spread to Conwy Estuary, threatening biodiversity.

During Invasive Species Week, Natural Resources Wales warns that the Chinese mitten crab, a non-native species threatening biodiversity, has spread to Conwy Estuary in North Wales. The crabs eat rare salmon eggs and mussels, damage river courses, carry diseases, and outcompete native species. To tackle this issue, NRW urges people to report sightings, practice biosecurity, and join local action groups.
