A Thompson Rivers University scientist says thousands of large, invasive goldfish have multiplied in bodies of water around the province.
“And so she produces clones of herself. So, they’re very good at spreading rapidly.”
Over the last decade, Heise says goldfish populations have spread from the Vancouver area to lakes in the northern and Interior parts of the province.An electric current is passed through the water to stun the fish, allowing them to be scooped up. Heise said the method allows native fish to be easily revived and goldfish removed.
“And it’s actually quite an expensive process. To go into a lake and shock for a couple of days would probably cost you $10,000.”
