Unwanted lockdown goldfish pose a triple threat to native species in UK waterways, study reveals
If that lockdown goldfish is starting to lose its lustre, think twice before throwing it in the river or canal – the creatures may look innocent but their voracious appetite, tolerance for cold and have-a-go habits compared with native species can be catastrophic for local wildlife.
New research shows that goldfish consume much more than comparable fish in UK waters, eat more than other invasive fish and are also much more willing to aggressively take on other competing species.
