Barring a sudden sub-zero freeze or a willingness for sturgeon to jump out of the water, the spearing season for 2011 on Lake Winnebago will go the entire 16 days, state Department of Natural Resources sturgeon biologist Ron Bruch said.
Bruch said 16 fish were speared on Thursday.
"That's a 78 percent increase in the harvest from yesterday to today," Bruch said Thursday afternoon. "We had nine fish speared on Wednesday and 16 today."
One of the fish weighed more than 100 pounds.
Bruch said 179 more adult female fish are needed to pop the 90 percent harvest cap for adult females, which would trigger a closure of spearing on Lake Winnebago.
"This season will undoubtedly last the full 16 days, so barring some miraculous rush of fish registration the next two days the season should run through 12:30 p.m. on Sunday," Bruch said.
The largest fish registered on Thursday was a 113.6-pound female registered at Stockbridge by Robert Schmitz of Chilton.
Thus far in 2011, spear hunters bagged 1,024 sturgeon on Lake Winnebago. Including fish speared on the upriver lakes, the season harvest is 1,375 fish.
