Growing number of 'invasive' goldfish in Kitchener pond sparks concern from locals, advocates
Social Sharing A rainy and gloomy Thursday afternoon didn't stop Aiden Roth from patiently waiting for some goldfish to bite in a Kitchener pond. "I just want to see if there's a chance I could get one," Roth told CBC News. Earlier that morning, Jim Penny, Roth's grandfather, read in a newspaper article that "a whole lot of [gold] fish" were sighted at a pond off of Spurline Trail in Kitchener. "[Aiden] wasn't feeling well this morning… [but] I know he's got a big interest in fishing," Penny said. "I showed him the article, and after lunch he said he was feeling a little better… so we thought we'd come over and see." Roth could not catch a single goldfish at the pond off of Spurline Trail. But he said he's noticed goldfish growing in numbers at a pond in the Lakeside Park, which is closer to his home. "Sometimes you'll find these holes in the ice in the shallower areas of a pond… there's like 20 goldfish in one hole two years ago," he said. "This year, just in the past winter, there [were] at least 100 per hole." While exciting for the young fisherman, the growth of goldfish populations in these local ponds is a sign of a growing environmental concern according to Terre Chartrand, a land-based educator from the Red Osier Guild in Waterloo region. She was at the Lakeside Park pond for World Turtle Day when she noticed that goldfish populations at the pond were getting out of hand. "Goldfish don't occur naturally in North America, but they've been released in [North American] waters since the 1600s," she said. "This is 100 per cent someone releasing a pet that they no longer wanted, or can't take care of, into the water." Chartrand, along with other experts, say goldfish are causing some issues in ponds like this one. The goldfish problem Jessica Kellerman, the manager of stormwater operations and construction at the City of Waterloo, says it's not uncommon to see goldfish in stormwater management ponds. "The size of the facility, the location of the facility, the proximity to houses or things like that would sort of dictate how many [goldfish] you might find in there," she explained. Goldfish are mainly acquired as pets. Chartrand says when pet owners think they can no longer care for these foreign species, they tend to believe that releasing these animals in the wild is the most humane course of action. "Some people think [releasing their pets into ponds] is the more merciful thing to do with their pets," she said. "It's certainly more merciful than… just disposing of them in a way that kills them." But the problem with goldfish – along with other invasive species – is that they bring a host of problems to their new habitat. Kevin McCann, a professor at the University of Guelph's department of integrative biology and the director for the Centre for Ecosystem Management, says goldfish are a "free willy" invasive species. "Goldfish are what we call high r species, and so they can be formidable competitors with native species as such," he said. A food web ecologist, McCann says such "runaway growth" could have impacts on a local pond's food webs and overall biodiversity. Goldfish also "increases water turbidity," which Chartrand describes as the "murkiness" of the water. "In their own water systems, [goldfish] would have different types of critters that would deal with that turbidity… but here we don't have those things," she said. "It creates a condition that becomes harder and harder for our own aquatic species to live in." When water has high turbidity, sunlight has a hard time penetrating the surface, which affects the pond's biodiversity as a whole. There's also the issue of diseases, which Chartrand says the local fish have "no ability to defend itself from." Goldfish can harbour "diseases, parasites, viruses, or bacteria," which can do harm to the native species in any one area. What could be done CBC News reached out to the City of Kitchener for comments on the goldfish situation at the pond off of Spurline Trail. They did not provide a response by deadline. As for Waterloo, Kellerman says the city hasn't had to "actively manage goldfish," but that they are "likely to implement a program to remove them" if the fish population goes out of control. Chartrand says when it comes to proper disposal of goldfish and other aquatic pets, the best thing to do is to reach out to organizations that have the capability to take in these animals. "Donate them to a school, or contact the place where you've got the goldfish from and see if you can relinquish it back," she said. "The last thing one should do other than just outright killing that pet is putting it in the waterways." Although he's only been fishing for a year, Roth shares the same opinion. "You could sell it somewhere… If you have a pond somewhere or know somebody with a pond, give it to them," he said.

It's World Turtle Day! Here's why they matter
Friday is World Turtle Day. It's a yearly reminder to protect turtles and their disappearing natural habitats. Terre Chartrand is a land-based educator from Red Osier Guild, a Kitchener-based collective focused on environmental conservation and survival. Chartrand told CBC K-W's Aastha Shetty about why turtles are important to parks and natural spaces in Waterloo region.

On World Turtle Day, this Kitchener educator shares why turtles are 'crucial' to nature
When the sun comes out, so do the turtles — right in time for World Turtle Day. "There's a lot that we can learn from the turtle," said Terre Chartrand, a land-based educator from the Red Osier Guild in Waterloo region. Land-based learning is an Indigenous practice that guides a person to understand nature by applying traditional knowledge and teachings. Chartrand says there are many interesting facts to share about the turtles living in Waterloo region. "Turtles adapted from this massive amount of wetlands to living in these little civic ponds. To me, that illustrates the resilience of the turtle. It can go from living in the most ideal circumstances to something that is largely fed by the storm water of the city," she said. "They're part of an ecology that makes that water more potable, more fresh, more clean. Their presence is pretty crucial in the ecology. It takes 60 years to replace a single turtle. They live to be up to 100 years old." Significance of the turtle Chartrand says turtles hold a special place in many Indigenous cultures across Canada. "For both Haudenosaunee cultures and Anishinaabe cultures, the creation story involves the turtle. For us, the turtle represents the land itself. In the sacred teachings, it represents truth and resilience." In the Anishinaabe creation story, the first woman to arrive on Earth, Sky Woman, is given a home on a great turtle's back. "There's just a bunch of virtues that turtles have," Chartrand said. "Sometimes if we say that someone is like a turtle, it means that they take more time. And if that time is a chosen time to take, then what are you learning because you're not rushing through life?" Chartrand is inviting people to join her and the Red Osier Guild for a turtle walk on Saturday at 2:30 p.m. at Lakeside Park in Kitchener. It's a free event. You can learn more about it by visiting the Red Osier Guild's Facebook page. Andrew Holland is a spokesperson for the Nature Conservancy of Canada. He says drivers should be mindful of turtles on the road. "They come up to lay their eggs. They mate. They like to sunbathe... But they're not very good at looking for cars," he said. "They'll be on sandy roadsides, they'll be along highways. It's really important to, at a bare minimum, keep a lookout for them." He says there are eight different species of turtles in Ontario, including snapping turtles, Blanding's turtles, wood turtles and painted turtles. All of them are at risk and all of their populations have been in decline. "The main reason is road collisions," Holland said, encouraging drivers to slow down when they see a turtle on the road. "If you're able to pull over to the side of the road and exit your vehicle safely, great... If you can, pick up the turtle and hold it like a hamburger with both of your hands, use gloves if you can, and carry it across the road. Then place it on the side of the road across the road and back away to give it some space." He says turtle season runs throughout the summer months, with their most active season starting in May.
