What’s behind Lake Erie’s steep yellow perch decline?

Lake Erie's yellow perch population has sharply declined by around 20%, according to Ontario's regulatory body, raising concerns among local fishermen and ecologists. Scientists attribute this drop to an increase in the walleye population, which competes with yellow perch for food, and climate change, which affects water temperature and habitat conditions. This decline could impact local fishing industries and ecosystems, highlighting the broader effects of climate change on freshwater environments.
