Sturgeon Spawning Update from Ron Bruch on April 26, 2011

April 26, 2011

The following update has been posted with permission from Ron Bruch and the Wisconsin DNR:

“Rain, rain, cool rain today which prevented the water temps on the Wolf River from continuing to rise so we are still stuck at a degree or two from getting close to optimum spawning range. A good number of fish moved in at the Sturgeon Trail spawning site on Highway X west of New London though and we tagged fish there all day ending up with 55 fish captured, tagged and released. Fish also are in, but not actively spawning yet at Shawano Dam and a few other obscure sites on private property. The high flows and water this spring in the Wolf River may limit the number of sites sturgeon can effectively spawn at, but could result in high concentrations at major sites like Cty X, Bamboo Bend and Shawano Dam when fish finally do come into these sites to spawn. This appears to already have started at Cty X.

We are going to attempt to take eggs tomorrow (Wednesday) at Cty X for the upper Fox River restoration project. There is not enough spawning activity anywhere else on the system to allow us to work at other sites. So – we work where we can and wait for the weather to warm up.
