My office today. Spent time with about a hundred middle school students from Two Rivers. It went pretty well. #GreatLakes

For the REEF theme of #SundayFishSketch and #SciArtSeptember I went with the Gag Grouper.

Rolling into the weekend it is time for the #SundayFishSketch #Fishytheme. Continuing our @lizlagomorph.bsky.social #SciartSeptember themes, 'Reef' is the prompt for this Sunday! There are thousands of reef fishes to choose from, and I can't wait to see all the colorful illustrations! #Sciart 🦑

Alright I have something useful for you to do. Think of any teachers and librarians you know. Do they know about Skype a scientist? Our program matches classrooms & other groups w/scientists for virtual Q&As. It’s free! They can sign up here! www.skypeascientist.com/sign-up.html #Edusky #StemED

Bioturbation in action. I was out collecting some data yesterday in a restoration area of a local stream. The graph shows the turbidity caused by a muskrat that showed up and started feeding on plants. The water was very clear when I got there but the muskrat stirred up things with its activities.

With funding from the Freshwater Collaborative of Wisconsin, Wisconsin Sea Grant supported 12 interns at aquaculture facilities across the state. It was a fun, busy summer filled with lots of learning! Hear what the interns had to say about the experience. www.youtube.com/watch?v=I9Eu...

"Saving our Sturgeon," a children's book about Wisconsin's beloved big fish, is out now! Written by Rebecca Hogue Wojahn, the book tells the story of how people came together to save the lake sturgeon – a prehistoric fish that can live up to 150 years. www.seagrant.wisc.edu/news/new-chi...

Could this whitefish be a hat? A drink? The elixir of life? 🧪 Submit your ideas on how to use the whole fish to the 100% Wisconsin Fish contest for a chance to win a #GreatLakes prize pack! www.seagrant.wisc.edu/news/submit-...

Thank you to everyone who made our session at #AFS155 a huge success - our speakers, our organizers, and our active and energetic audience! You can find more photos from our session on our Instagram page! Follow us @afs_scicomm See you next year in Columbus?!

MN AFS members Solomon David of @garlab.bsky.social and Alec Lackmann, leader of the Otolith Lab at UMN Duluth both received an Award of Merit from the @amfisheriessoc.bsky.social Fisheries Management Section, recognizing significant contributions to management of nongame fishes. Congratulations!!

For the Mimic theme of #sciartseptember and #SundayFishSketch, it's the mimic shiner! Probably because it looks like other shiners. Thanks shiners... #GreatLakes

Continuing to follow our #SciartSeptember #SundayFishSketch #Fishytheme this month with @lizlagomorph.bsky.social, this weekend's theme is 'Mimic.' There are so many fantastic fish that mimic other things, including inanimate objects, other animals, even other fish! #sciart 🦑

1/2) I am excited to share my just published book review in Nature Ecology and Evolution with the #SundayFishSketch community! 'Ocean Art' by @helenscales.bsky.social is a delightful read and will be enjoyed by ocean lovers and artists alike! #Sciart 🦑 www.nature.com/articles/s41...

Yesterday I headed over to Fremont, WI on the Wolf River to help prep for wild rice seeding that the Brothertown Indian Nation is doing. We collected some sediment at two sites, mixed up seeds for several sources, and made mud balls for seeding. They are seeding today and tomorrow! #restoration

While this job would undoubtedly be a career advancement, I'm not sure I can sign on for "continuous sitting"! I already do too much sitting, especially in the non-field season. I guess it's time to give up on career advancement?

Manoomin (aka wild rice) is an aquatic grass, so wind pollinated. But the flowers have a great purple color. This rice bed has flowering plants alongside mature seeds. #GreatLakes

For the boreal theme of #sciartseptember and #SundayFishSketch, a burbot! This freshwater cod species is found from the #GreatLakes and Midwest north to the boreal regions.

For the week of September, #SundayFishSketch #Fishytheme s will be following along with @lizlagomorph.bsky.social #sciartseptember! That means, this Sunday's theme is "boreal!" There are so many fantastic northern/boreal fishes. I can't wait to see some sketches! #sciart 🦑

I'm assuming that Naomi Osaka doesn't actually use Workday, but I guess I'm glad she gets some money from the company that has made my job more of a headache!

I realized this morning that yesterday was Sunday and I missed #SundayFishSketch. I did sketch some wild rice seeds, so that's at least aquatic. Here's a belated baby smallmouth bass. Lots of these around the islet of Detroit Island. #sciartseptember

Wild rice, dead trees, and an eagle. #GreatLakes

What am I expecting when I check my mail at work? Something exciting? This month's issue of Fisheries? It's probably about the potential for random treats.

Hey everybody! @drjuliawester.bsky.social and I have a new paper! We surveyed over 800 scientists, science communicators, and science educators who use social media. Conclusion: Scientists no longer find Twitter useful or pleasant, and many have switched to Bluesky! 🧪🌎🦑 doi.org/10.1093/icb/...
