Leah Kongsrude, St. Albert's environment director, says she's seen captured goldfish up to 30 centimetres in length, compared to ones sold by pet stores that measure only about two centimetres
ST. ALBERT, Alta. — Workers have dipped nets and a naturally occurring chemical into a storm water retention pond near Edmonton in a bid to kill thousands of unwanted goldfish that have made the water body home.
Officials say the aquatic invaders are the result of goldfish reproducing after people released their unwanted pets into the wild or flushed them down the toilet.
Leah Kongsrude, St. Albert’s environment director, says she’s seen captured goldfish up to 30 centimetres in length, compared to ones sold by pet stores that measure only about two centimetres.
Kongsrude says goldfish are hardy and can out-compete naturally occurring species for food.
Crews used nets on Tuesday to remove the reddish-gold swimmers and also applied the chemical, Rotenone, which is used to remove unwanted fish species from fresh water.
The pond will be checked later on to determine whether the cull was successful, and workers will also watch another nearby body of water to determine whether goldfish have taken up residence there.
Kongsrude said the city is lucky the fish are just in the pond and not in the Sturgeon River, which flows through St. Albert.
“We pumped this pond down and froze it right to the bottom in the winter and they were back in the spring. So they can live with very limited oxygen and low water temperatures.”
Officials are also reminding residents to not release any fish into any pond or body of water in Alberta — including flushing Goldie down the sewer.

OK.
Here’s what we do.
We wait until the pond freezes.
Then, and this is a beauty, we have Wayne Gretzky come in and shoot these carp pucks into the back of a pickup truck and ship em to Venezuela.
Catfish love goldfish.
Release some channel and blues and before long you’ve got a primo fishing hole and eating!
Of course eventually you have to release aquatic chimpanzees with spearguns to control behemoth, man-eating flatheads.
They tried that.
The fish returned in spring...................
That’s a lotta carp!.....
#6 If they ever get into the Great Lakes!!
I think I have this figured out.
Lots of people from Edmonton head to Las Vegas for the winter.
They are obviously taking these goldfish with them.
Then, they bring the goldfish back with them in the spring.
It’s like the salmon in Alaska, only the goldfish are in Winnebagos.
Well, that’s ONE explanation.....................
Really??!!???
Hmmm, hits right at home here.
It’s the only one that makes sense.
These Candian goldfish are down in Las Vegas in the winter playing the slot machines and betting on the Ferris wheel when they aren’t eating at the buffets or watching the chorus girls or listening to Celine Dione.
Well, some of them are in South Florida all winter driving 25 MPH in a 40 MPH zone...................
Wrong type of algae eater - plecostamus. Quality fish storess only sell these for ponds. They grow to 4 feet long. There are many much smaller algae eaters that are perfect for aquariums. Look for a bushy nose or rubber lip pleco.
Correct. It is not te size of the environment. It is the quality. I grew a 12” fish in a 10” tank by doing daily water changes and lots of food.
We have no choice.
We have to nuke them.
Wait, that will make them bigger.
Why not just declare open season and let the fishermen have at them?......................
That’s probably a more sensible approach.
Mekong Delta fishing tackle would work. Also known as the concussion grenade.
The old electrical generator trick would as well............and a lot quieter.....;^)
