      The annual sturgeon spawning run looks like it will be a little later this year.[caption id="attachment_20933" align="alignleft" width="300"] Spectators watch sturgeon at the Shawano Dam, May 1, 2013. (WLUK/Angela Kelly)[/caption]Because the Wolf River is still frozen, DNR biologist Ryan Koenigs says he expects spawning to begin in three to five weeks.Typically, spawning takes place in mid-April, mostly in the Wolf River as the fish swim upstream from the Lake Winnebago system. Water temperatures in the 50s trigger the fish to spawn; the activity is popular with spectators as the large fish come very near the shore.Koenigs says the water still needs to warm up about 20 degrees for spawning to start.
