From there the native species — the catfish, suckers and sunfish — will be trucked to another pond and released.
The non-native species — the carp and goldfish — will be destroyed. These invasive species actually ruin the habitat by eating just about everything, stirring up sediment and uprooting aquatic plants. The water becomes murky and sunlight can’t penetrate. The invasive species carry parasites and can disrupt the genetic line of native fish, as well.
“They basically take over the entire ecosystem,†said Melissa Ryan, the city’s design and construction project manager. “The native fish that are meant to be in this type of pond are pushed out.â€
Goldfish and carp should never be released into Victoria Park Lake or other water bodies, Ryan said. Nobody should feed the fish, either.
“We see this as an opportunity to educate the public,†Ryan said. “It is an opportunity to let people know that not everything belongs in this lake. A tiny little goldfish turns into a huge, huge ecosystem nightmare basically.â€
