Welcome new Bluesky folks!

I'm Titus, an aquatic ecologist and fisheries specialist with Wisconsin Sea Grant. I work on all things #GreatLakes and freshwater from teaching 6th graders on a beach, surveying fish in a coastal wetland, or getting seasick on a commercial fishing boat!

Bearded old guy in a canoe (he looks tired) with a big handful freshly harvested wild rice.

Man in waders with a sledgehammer. Is that the Dr Fish mobile? Sure it. A red and black checked flannel? Seriously? Looks like he's ready to install a sucker monitoring station in Silver Creek, Manitowoc, WI.

Live cooking demo? Why not, this is what you trained for as a scientist! The chefs show off their dishes, a smoked salmon candy salad on the left from the bearded guy and some sizzling salmon in a pan from colleague Sharon Moen. The chefs look very stylish in their Eat Wisconsin Fish aprons! Check out eatwisconsinfish.org

The Ridges Sanctuary in Door County is known for its unique ridge and swale ecosystems and rare, endangered species. But UW–Madison's Steve Loheide is most interested in what’s going on underground. Read more about this new WRI-funded research: https://www.seagrant.wisc.edu/news/the-swale-tale/

Fortunately much cooler today. Looks like they're getting rain up there but so far it's missed Manitowoc. Although I appreciate the clouds with my south facing office!

Peshtigo Fire season again (Oct 8, 1871). It has been very dry this year, so it might feel a bit like 1871. Probably not that dry though.

My kids have been complaining about Kraft Mac and Cheese recently too. It tastes "bad." I wonder if that was a recipe change too. All filler, less killer cheese?

Nothing says soup season like highs in/near the 80s!

Maybe next week (although there's never a bad time for a fish chowdah).

How about a baby round whitefish. I had to id one once. It took a while to get from the minnow key to the whitefish key!

Side view of a juvenile: The sides show faint pigment blotches along the posterior flank and smaller blotches dorsally.
