I needed a map showing the range of the Paddlefish (Polyodon spathula, also known as spoonbill catfish, among other things), one of North America’s most striking animals. Despite a lot of searching (online and in books), however, I couldn’t find any map that was both up-to-date and of sufficient quality. I also couldn’t find any single listing of the species’ current status in all states where it is found, nor the regulations governing if/how it can be caught (for sport or commercially). What else could I do but create the map I needed?*
UPDATE: Thanks to information provided by Jason Schooley (Paddlefish Biologist at the Oklahoma Dept. of Wildlife Conservation Paddlefish Research Center) and Ben Neely (Kansas Department of Wildlife, Parks, and Tourism, and see the two articles I’ve added to the sources list at the end of this post), I have updated the map to include more of Kansas, Oklahoma and Missouri in the Paddlefish’s range.
The map was created to accompany a paddlefish article in the fall 2014 issue of American Currents. (Click on the map to see it larger.)
Note: As noted in the key below the map, PA and NY have paddlefish populations. They are shown in the extirpated color because the species is still officially considered extirpated by both states. When that changes, so will the map.
Corrections welcome, but only if they come with reference to sources so I can verify and keep track.

If, for some reason, you want to use the map in something commercial, contact me. If you need it altered somehow, contact me.
Additional notes on the paddlefish:
The last time a wild paddlefish was seen in Ontario was 1917.
Paddlefish roe (eggs) make fine caviar, and as is the case with many species of sturgeon, this fact has had a negative impact on the species’ population. Tight rules now govern the harvest and sale of paddlefish roe, but poachers still take fish illegally as there is money to be made.
Read the journal of just about any early European explorer traveling up the Mississippi and you’ll find references to the paddlefish. They must have been extremely common before we fished, dammed and poisoned them to their current reduced state.
- In about 1805, Zebulon Pike, traveling the Mississippi somewhere around what is now southern Illinois/Missouri recorded this:

- Father Louis Hennepin, in (I think) 1680, compared a Mississippi River (he called it “the River Colbert”) paddlefish to a devil:
“The eagles, which are to be seen in abundance in these vast countries, will sometimes drop a breme, a large carp [there were no carp on this continent at the time, so he meant either various suckers or perhaps mooneye, goldeye, or drum], or some other fish, as they are carrying them to their nests in their talons, to feed their young. One day we spied an otter, which was feeding on a great fish upon the bank of the river [some versions say “River Colbert” here]; which fish had upon its head a sort of beak about five inches broad, and a foot and half long. As soon as the Picard spied it, he cried out he saw the devil between the claws of the otter. This surprise was not so great, but that we made bold to feed heartily upon it. The flesh of it was good; and we named it the sturgeon with the long beak.”

- One of the earliest illustrations appeared in the account of Antoine Simon LePage DuPratz (1695-1775), who traveled to North America in 1718 and spent 16 years living in “Louisiana,” a larger area then than now. His memoirs provide a wealth of information about the native people and animals of the region. Here are a few pages on fish and fishing, featuring suckers (what he calls carp are probably suckers of various species, since carp would not arrive here for another century or more; a later author, mentioning DuPratz, identifies the carp as buffalo, which makes perfect sense), gar (“armed fish”), catfish (at least that’s how I would identify his two kinds of “barbel”) and bowfin (“choupic”). If he did nothing beyond this, I’d still consider him a great man: he calls the bowfin beautiful and says many people confuse it with trout for its willingness to take a fly!
A few pages from the chapter on fish:

I don’t know whether the illustrations are based on sketches by DuPratz or wholly created by someone who had never seen any of these animals (which happened a lot, leading to some wildly inaccurate images), but they combine a simplistic style uncommon for animal woodcuts in books of this time with a surprising lack of the fantastic over-imagination also common at the time.

*Making things like this is part of my real job (loving unloved fish is, for me anyway, not a paying gig) as a book designer (mostly the pages, but also covers). I specialize in scholarly and scientific books and journals. If you are a scholar or scientist who needs someone to design your next book or the journals you edit, please get in touch.
Hello! I am a student at the university of Iowa currently studying environmental science and sustainability. I’m working on a research project for my GIS class about the effect of dams on paddlefish population, and I cannot find much exportable GIS data, I was wondering if your department had any data I could use, fisheries biology is something I am extremely interested in, anything would be extremely helpful, thank you!
I do not have any such data, and I don’t have any good ideas about where to look. Sorry.
