The charity making life better by water

Invasive and non-native fish

Our rivers, canals, lakes and ponds are under attack. Plants and animals from other countries are finding their way into our waterways after being imported for ornamental or agricultural use.

Many of these foreign species wither and die, as they're not adapted for our specific climate. Others survive, but don't spread rapidly. A few spread like wildfire, without the natural controls of diseases, predators and grazers that exist in their native country. They can therefore do massive damage to our water, environment and fisheries.
