For #SundayFishSketch this week, an in-progress Coregonus kiyi. I’m working on an activity for the general public on why we use genetics to distinguish between species, and my current study system of ciscoes is more than a little notorious for being hard to morphologically ID reliably

Not all fall-blooming flowers are to blame for seasonal allergies. If you're sneezing, ragweed and its airborne pollen are likely the culprit, but showy goldenrod blooms often get accused.

Have you ever seen a baby gar eating?

This little Spotted Gar is about a week old and has started feeding on zooplankton (in this case brine shrimp/Artemia/ aka "sea monkeys").

Swimming drone explores underwater mountain in Lake Superior

The Superior Shoal is a mass of underwater volcanic rock that rises out of the floor of Lake Superior. Researchers and filmmakers think it could be a magnet for life beneath the surface.

Harvest theme to wrap up the #SundayFishSketch and #SciArtSeptember collab. The lake whitefish is an important and delicious species for the #GreatLake commercial fishery.

For harvest, the most harvested fish in Michigan is the Lake Whitefish. If you drive through the UP you’ll see lots of signage about places to purchase these guys either fresh or smoked. Unfortunately, they’re currently in decline #SundayFishSketch #SciArtSeptember

Bloodsucking parasite, but it’s a native fish!

Check out this native lamprey (compared to invasive Sea Lamprey) on a Northern Pike in a Minnesota River.

Parasitic lamprey species attached to hosts, rasp a hole and suck blood (but native species don’t typically cause death). Both fishes released!
