It’s Fish Fry Day – the day when Wisconsin puts fish on the menu and we serve up a fish o’ the day on our blog. But today, we’re launching an epic challenge – a quest to bring you tidbits of knowledge for each and every species of fish in Wisconsin.
Perhaps you missed the news (or our incessant social media bragging on the subject) but there is an AMAZING new poster hanging in our halls ( you, too, can buy a copy and support the UW-Madison Zoological Museum) featuring 183 species of Wisconsin fishes. Even more amazing is that they’re all drawn to scale (sorry) – their average adult size, to be exact.
In an article posted on the UW-Madison website, artist emeritus, Kandis Elliot, from the Department of Botany, explains why she chose to switch from things with leaves to creatures with fins:
“The idea behind the posters is to create a splash,” Elliot deadpans. “There is a wow factor. We want people, especially kids, to have an awareness of all our fishes, not just hook-and-line species.”
We couldn’t agree more, Mrs. Elliot!
So, in honor of your fine achievement, we are embarking upon our own crusade. Each Friday, working from the top left corner of the Fishes of Wisconsin poster, down to the bottom right (which is more than 13 feet away!), we’ll bring you a morsel or two of information regarding a fish. On the poster in our hallway, at least, that means the humble suckermouth minnow is first up – sitting in pole position at the top left corner, barely longer than the head of the bass lurking below it.
Suckermouth Minnow – Phenacobius mirabilis
First let’s get something important out of the way – “minnow” does NOT mean “small fish.” While minnows are most often small, not all small fish are minnows and not all minnows are small.
In fact, minnows make up a family of fish called Cyprinidae which is the largest family of fish, boasting some 2,000 different members, including everything from tiny two-inch shiners to a 3-foot long carp. Even the iconic pet goldfish is a member of the family.
All that said, the suckermouth minnow pretty much looks exactly like what you’d expect – a small, long, silvery body, spineless fins and a toothless mouth. Giving it it’s name, this particular minnow’s mouth is downward facing although, like many minnows, it’s used for gobbling up aquatic insects, not algae.
Suckermouth minnows are found mostly in the swift-flowing riffles and gravel runs of mid-to-large sized rivers.
Native to the U.S., the historic range of suckermouth minnows was a large swatch of the Mississippi River Basin. That range increased in the late 1800s and early 1900s as early settlers cleared the nation’s forests and prairies and converted them to farmland. That land-use change led to runoff from freshly ploughed fields and led to muddier, murkier waters – a condition the suckermouths apparently favored.
Suckermouth minnows (like many smaller minnows) are an important food, or forage fish, for all sorts of predators (think blue herons, bass, etc). As a result, they’re also popular bait fish for anglers. AND, as a result of that, they haven’t only moved into new habitats on their own volition. Most likely carried in by bait buckets, populations of suckermouth minnows have been recorded as far afield as Lake Erie and the Pecos River.
And that, dear reader, is all of the things we (or your trusty blogger, at least) know about suckermouth minnows.
We’ll be back next week as we continue our Fishes of Wisconsin quest and offer up some info on the next species on our gigantic poster – the largemouth bass. Stay tuned!
