ALBERTA CANADA (CNN) – Officials in Canada say dumping of live goldfish into the ecosystem has resulted in freakishly large fish.
The invasive species has no natural predator and is thriving in poor water conditions.
A biologist in Alberta says the biggest goldfish they’ve caught is the size of a dinner plate.
Officials estimate that hundreds of thousands of goldfish are in flowing rivers and waters.
In Canada, it is illegal to dump or transfer live fish from one body of water to another.
Aquarium owners who no longer want their finned friends have a few options:
- Contact a retailer for a possible return
- Give the fish away
- Donate it to a school, or talk to a veterinarian about humane disposal.
