Our field crews have been out monitoring for invasive species but catch many other fish as well. Here is a very thick pre-spawn walleye that found it's way into a net near Dubuque and we snapped a quick picture before it was released. This one has an extra stocky build to it.

In this picture our lake sturgeon is doing a nice job of showing off it's specialized adaptations for life on the bottom of a river. Notice it's flat shovel shaped nose, taste sensing barbels, downward facing mouth, flat belly, and protective bony plates (scutes). This body plan has gone relatively unchanged in the sturgeon family for the past 200 million years and there is no sign of it changing. Nature doesn't mess with success!
