Salmo trutta) or other non-natives (northern snakehead, Channa argus) can thrive in new environments.
Unfortunately, their success may be at the expense of native fishes. Some introduced species are more
aggressive than native species and can outcompete the natives for food and habitat. This leads to losses in
biodiversity as the native fishes are displaced or die because they cannot co-exist with the introduced species.
