Where Did Fred Go?
Meet Fred, a frequent flier in the DNR’s Muskellunge Age and Growth Study. Fred’s been around the metaphorical lake a few times.
In 2009, he was raised in a hatchery. Upon reaching 10.8 inches long, he was fitted with a PIT (passive integrated transponder) tag and stocked into Sand Lake in Sawyer County.
The next time Fred made an appearance was in 2015. Scanning his PIT tag showed that he had more than tripled in length, measuring an impressive 34.5 inches. However, Fred must have liked saying hello because he was picked up and scanned again in 2016 and 2017.
In 2021, Fred was picked up and scanned twice more, once by the DNR and once by an angler, totaling six PIT scans so far in his life.
Interestingly, both 2021 scans took place in Lac Courte Oreilles, meaning Fred had managed to move two lakes over! The most recent of these scans, in August 2021, showed him measuring in at a hefty 41 inches.
The data pulled from these specific intervals is currently helping scientists learn valuable information about musky growth rates and their stocking success; learn more about the study with the DNR’s Musky Age and Growth Study factsheet. |
