Dont Flush Goldfish Down the Toilet!
Monster goldfish the size of dinner plates have been discovered in ponds in western Canada.
The domestic fish are multiplying rapidly in the wild and appear to be growing far bigger than when stuck in a fish tank.
The government in Alberta province – where the giant goldfish have invaded – says the problem stems from people flushing their pet fish down the toilet.
It has now issued an appeal to stop people flushing goldfish.
Officials are concerned that the presence of the goldfish – considered an invasive species – threatens other aquatic animals.
In one case, 40 of the domestic fish species were pulled from a stormwater pond.
“It’s quite surprise how large we’re finding them and the sheer number,” said Kate Wilson, aquatic invasive species coordinator at Alberta Environment and Parks to CBC News .
“That’s really scary because it means they’re reproducing in the wild, they are getting quite large and they are surviving the winters that far north.
“Approximately a third of invasive species out there that threaten native aquatic environments are from aquariums and the ornamental trade.”
The government’s campaign even applies to dead goldfish as they may carry disease or parasites.
Pet aquarium fish are being dumped in rivers where they damage unique local ecosystems by growing up to twenty times their regular size.
Goldfish are being caught weighing up to 2kg and koi carp up to 8kg and one metre in length, in the waterways of Western Australia amongst other exotic introduced species.
‘A lot of these fish are much larger than the native fish, so they prey on them and compete for habitat,’ Dr David Morgan, the Director of the Centre for Fish and Fisheries Research at Murdoch University, told Daily Mail Australia.
