Interpretation
Key Result: The abundance of Golden perch was similar between all three years. Young-of-year fish were detected in 2018 and 2019, possibly indicative of recent stocking. A high percentage (<79%) of the overall catch were legal size fish.
Stocking: In 2016, 80,000 Golden perch were stocked; 88,000 in 2017; and 150,000 in early 2019.
