First Occurrence of a Juvenile Chain Pickerel (Esox niger) in Ontario Waters of Lake Ontario

Brian P. Morrison, Daniel J. Moore


This paper documents the first juvenile Chain Pickerel (Esox niger) captured in Ontario waters of Lake Ontario. It was found during August 2016 monitoring activities at Port of Newcastle. Its occurrence represents a significant westward range expansion from recently documented adults in the eastern basin of Lake Ontario/Bay of Quinte/St. Lawrence River, likely colonizing from United States waters of Lake Ontario.
