Meet the Marbled Crayfish | Great Lakes Now

There’s an invasive species in Ontario that has wildlife experts on high alert. It reproduces asexually and can lay 500 eggs at a time. Meet the marbled crayfish. The marbled crayfish was popular in the aquarium trade as both a pet and as fish food. Since 2022, it’s been listed as a prohibited species under Ontario’s Invasive Species Act, meaning it could not be bought, sold, traded, or kept in home aquarium. But that hasn’t stopped the marbled crayfish from invading Ontario’s waterways. For more than 30 years, Ontario’s Invading Species Awareness Program has been on the frontlines in the fight against invasive species. Learn how they’re tackling this new threat to Ontario’s ecosystems. This story was produced by our partners at ‪@tvo‬. VISIT https://www.greatlakesnow.org/, a Detroit PBS initiative.
