Researchers say releasing pet goldfish into the wild has grave consequences on the environment.
A new study published last month in the Journal of Great Lakes Research details how scientists are now tracking goldfish from Lake Ontario to learn how to control the species better. The research involved capturing 19 adult goldfish between June 2017 and October 2018 and implanting them with transmitters. Through the transmitters, the scientists were able to track the goldfish movements for pattern analysis at a later date.
According to Nicholas Mandrak, a biological scientist at the University of Toronto, “There are millions of goldfish in the Great Lakes if not tens of millions.”
