Minnesota's great spearfishing mystery has been solved.
Fisheries managers, resort owners and even spearers themselves were shocked to see the sale of spearing licenses jump by 8,000, or a whopping 44 percent, this year after decades of flat or declining sales.
Some speculated that the opening of Lake Mille Lacs to northern pike spearers for the first time in 32 years may have prompted the spike. Others cited a recent change in state law that required senior citizens to buy spearing licenses.
Both, it turns out, were likely factors, but officials say there were others, too.
After examining license sales data and mulling over the puzzle, Department of Natural Resources officials now believe there were multiple reasons why the agency sold more than 26,000 spearing licenses this season. Among them: expanding the number of lakes where spearing is allowed (including Mille Lacs) lower-priced spearing licenses, requiring seniors to buy licenses and ideal ice conditions and a lack of snow, which allowed spearers and anglers to travel unimpeded on ice beginning in November.
"Certainly the seniors contributed and Mille Lacs contributed [to the increase], but they weren't the whole story," said Ed Boggess, DNR Fish and Wildlife Division director. "It was puzzling at first, but it was the coming together of all of these factors."
Terrible ice conditions last year also played a major role in the mystery.
