PETALING JAYA: Our freshwater fish are being driven to extinction, while riverbanks are facing massive erosion which could pose risks to urban infrastructure, especially in major cities like Kuala Lumpur.The culprits in both cases is an invasive species of fish. Or three species, to be precise.
These fish burrow into the sand at riverbanks, destabilising them and causing erosion. When the river gets swollen during heavy rain, it could lead to the collapse of the banks.
