Canada –

Goldfish is beginning to be seen as a major problem in some parts of Canada. The reason for this is that fish whose natural habitat is in Asia are increasingly exploding in population. The government and conservationists are also confused and looking for solutions to overcome them without endangering native species.

In the city of Ontario, it has been observed that there are many ponds filled with thousands of goldfish which are considered dangerous pests because they prey on local species and destroy their habitat. In the Great Lakes, goldfish numbers have increased since 2015, according to ecologist Jennifer Bowman of the Royal Botanical Gardens.

“It’s only getting worse right now. These goldfish are very successful if they’re together. A few goldfish in the pond could be thousands next year,” he said. detikINET from CBC, Thursday (5/19/2022).

To deal with it safely, currently being formulated in several ways. Solutions include lowering the water depth level or using certain chemicals.

But the use of chemicals can kill all species in the waters, not just goldfish. If such a measure is taken, it is necessary to add more native species to the target waters.

Brydon Rodd, a local biologist, said it was also possible to catch goldfish one by one, but it was clear that a lot of effort had to be put into it. “It will be a major operation. It will take a lot of people and it will also be very expensive,” he said.

Preventive measures are also considered necessary to be encouraged. For example, providing intensive education so that residents do not arbitrarily release goldfish pets in lakes or rivers because they harm the environment.
