After the crab flood left the Canadians helpless, the beautiful and innocent-looking goldfish were driving them crazy again...
This is not an ordinary goldfish, but a "big Mac" in a goldfish.
It is not a batch of two batches, but it seems that suddenly there are thousands of them, which inevitably makes the locals panic.
You may think that people's reactions are a bit exaggerated, can you know how big these goldfish are?
Let's take a look at the pictures to get a feel for it:
These goldfish are ten times the size of ordinary goldfish! A lot bigger than football!
It's no exaggeration to say that even adults need to hold it with both hands.
Even Canadian scientists were shocked by these goldfish...
Not to mention, these goldfish are harmful to Canada's environment and not beneficial.
Some time ago, Canada's Department of Fisheries and Oceans released some photos of on-Board goldfish in Ontario.
You read that right, these people are carrying either balloons or ornamental goldfish native to Asia and where we often put them in fish tanks.
I can't believe that the small goldfish in Asia can swell into such a way when they run to Canada, and it feels like they are really koi.
According to scientists, these fish are actually domestically raised goldfish that have escaped from small fish ponds in some people's yards or been discarded.
Who would have thought that they had escaped into the wild and become what they are now.
This is really not in some fish farm, but in a freshwater lake.
In one water in Ontario, scientists found more than 20,000 goldfish at once, each of which was such a giant...
The subsequent discovery was even more shocking:
In addition to Ontario, goldfish are fast becoming one of the most prolific invasive species in North America in Canada's Alberta, British Columbia, Saskatchewan, Manitoba, and the United States.
Radio Canada International reported that researchers at the University of Toronto believe that a flood of goldfish is spreading.
The small goldfish in our fish tank are only a few centimeters long, but the average length of the goldfish swimming around in those lakes is 25 centimeters, and the longest goldfish recorded by scientists has grown to 40 centimeters...
Not only is it long, it is also very heavy, and a goldfish can weigh more than 3.5 pounds at any moment...
These colorful, cute and festive looking goldfish really make scientists feel bad.
You are growing up so crazy, how can our local fish live!?
Scientists say one reason goldfish have become so common in Canada is that people think goldfish are good-looking and harmless.
But Nicholas Mandrake says that once they enter the city's ponds, goldfish begin to feed on the insects in the ponds.
Goldfish spawn quickly, in large numbers, and have a large appetite, meaning they compete with amphibians and other organisms, reducing the diversity of native species.
He went on to say that when ponds flood, goldfish also escape and enter wetlands, streams, rivers and lakes, where goldfish become predators, eating the eggs and fry of other fish.
Coupled with the feeding habits of goldfish, it will not only destroy the rhizomes of aquatic plants, but also make the lake turbid.
Professor Nicholas Mandrake explains that in fact, goldfish have been in Ontario's wild waterways since the 19th century, however, what has changed is that their numbers are now very numerous.
He said this may be related to the increase in suburban rainwater pools, as well as the changing climate, which provides more favorable conditions for the fish to grow.
He went on to say that we believe climate change is playing a role, with water temperatures in the Great Lakes waters and urban ponds higher than before and appearing to be better suited to the survival of goldfish.
So now everyone must pay attention, if the goldfish in their own home do not want to raise, do not throw away the "release",
Goldfish are not always so small and beautiful, and after experiencing barbaric growth, the Canadian government may have to spend a lot of money and manpower to clean them up.
And the goldfish is not like a crab, this time even the Chinese foodies can not do anything,
"Sorry, we really don't eat goldfish...
