If you’re thinking of setting your goldfish free in a nearby river - DON’T DO IT, YOU’RE RUINING EVERYTHING!
This is crazy you guys.
The Centre Of Fish And Fisheries at Murdoch University have been trying to control a massive problem in Western Australia’s Vasse River for the past 12-15 years!
The giant fish have been causing a severe impact on our native fish and ecosystem, and it turns out us humans have played a part.
Researcher, Stephen Beatty, has revealed to Mashable that a lot of it comes down to people setting their the aquarium fish free:
“We think it's a major factor, people letting their aquarium species go. Unwanted pets, basically. They can do quite a lot of harm.
The key thing is if you've got unwanted pets, you can see if the pet shops will take them back. But if you're going to euthanise them, putting them in the freezer is the most humane way.
But just letting go of a pet, no matter how innocuous you think it is in your aquarium, or how pretty it is, can potentially cause a lot of damage. Not all fish you let go will form a self-maintaining population, but we're finding more and more that do."
The wild omnivore goldfish are deteriorating the water quality, feeding on our native fish eggs and spreading disease.
So just how big are these fishies?
The researchers have reported on at a whopping 1.9 kg, and another had travelled a massive 230kg in a year!
Looks like Magikarp has finally become Gyarados.
