Andrew Stevens is a graduate student working on a master’s degree both with Pete McIntyre in Freshwater and Marine Sciences as well as the Water Resources Management Program here at UW-Madison. He’s also an avid ice angler and handy with a camera. Click the link to see how some migratory fish are braving the winter in Wisconsin.

Have you ever seen Paddlefish (Polyodon spathula) feed? They use their sieve-like gill rakers to filter food (typically zooplankton) from the water column; hence "swimming around with their mouths wide open." Check out these juveniles at feeding time at Shedd Aquarium (video by CFL/Shedd Post-doc Solomon David)

Jason Ching, a fish technician at the University of Washington, made this incredible underwater, time-lapse, and drone video as part his field time in SW Alaska. Click HERE to see a video he made from this summer, including some great shots of salmon migration and spawning around lake Iliamna.
Followers of the Center for Limnology blog will know that Solomon David, a joint UW/Shedd Aquarium post-doctoral researcher, is an unapologetic lover of prehistoric fish and a whiz with a GoPro camera. Here's his recent encounter with a bowfin.

While post-doctoral researcher, Solomon David, prefers more primitive fishes like the northern pike he was recently catching, tagging and studying during their annual spring migration run, he also stumbled across (okay, waded into) a more modern fish migration. Enjoy this great underwater footage of walleye on the run.

Lurking in the waters of a Chicago harbor, Solomon David plunked a GoPro camera into the water and caught a cornucopia of silver-sided gizzard shad schooling along the shoreline.

Thanks to funding from the Great Lakes Restoration Initiative, former CFL graduate student Dan Oele is out in Green Bay trying to figure out to see if pike return to their “birthplace” to spawn or if any ol’ tributary will do.

The round goby has dramatically altered Great Lake food webs since it was first discovered in Lake St. Clair in 1990. But the aggressive invasive has spread beyond the blue borders of our Great Lakes. What might gobies mean for the tributaries and streams they are now colonizing? The UW Sea Grant Institute put together this video of the CFL’s Jake Vander Zanden and his (then) grad student, Matt Kornis, as they set out to answer that question.
