In total, nine fish over 100 pounds were speared on day three of the 2021 spearing season. Today’s largest fish on the Winnebago System was an F4 female speared by Thomas Luedtke on Lake Poygan, weighing in at 153.3 pounds (77.0 inches). It was registered at Boom Bay.
Today, the largest fish harvested on Lake Winnebago was a 123.8-pound (76.3 inches) F1 female speared by David Schneider and registered at Calumet Harbor. As an F1 female, David’s fish was in the first reproductive stage of a new reproductive cycle. Winnebago System female lake sturgeon will spawn, on average, every 3-5 years.
It is estimated a female lake sturgeon on a 4-year reproductive cycle may remain in the F1 reproductive stage for up to approximately 2 ½ years.
