Freshwater oysters?

I’m reading some blurbs taken from an 1896 Cadiz, Ohio newspaper and I see this line:
An oyster supper and social will be given at the Hotel Stone Friday evening, Dec 23rd.

Are there freshwater oysters? This appears to be a casual affair, not some fancy affair where they could afford to have oysters shipped in from the coast, so I’m assuming there must be a freshwater oyster that grew in a local lake, or river?
This is NE Ohio.

It’s before coffee, and a search on “freshwater oysters” turns up a bunch of site selling ‘freshwater pearls’. Not awake enough to dig deeper.

I have some books on the Old West. I remember seeing photographs of mining towns in which there are banners or signs advertising that an establishment has fresh oysters. Apparently it was not uncommon for oysters to be shipped in from the East Coast.

Freshwater Mussells for sure…And I think the pearls come from those… Never heard of fresh water oysters though.

I’ll be damned. Still seems kinda’ spendy for a town social, but what do I know. Thanks Johnny.

Try picking up The Big Oyster: History on the Half Shell by Mark Kulansky. Among other tidbits were the oysters were shipped all over the world from New York City (the oyster capital of the world at the time) in the 19th century. The could be shipped in ice, but were also shucked and shipped without the shells (lower shipping costs – a barrel without the shell held more oysters than unshelled, and they could be used in recipes.

They weren’t particularly expensive: Oysters were easy to find, and by the 19th century, they were extensively farmed. But it was a low-maintenance crop (once the spats – the free-floating larvae – attached themselves, you just let them grow), and they grew quickly in NYC harbor. During harvest time, you’d get a boatfull in a few hours. A good oyster shucker could remove hundreds of shells an hour, and you’d just fill the barrels and ship them off. Live oysters were even easier to ship.

They were a little bit more than local food, but the price was low enough that they weren’t out of the price range for any event that wanted to serve a special treat.

They were packed with cornmeal for a reason. the Oysters would take in the corn meal and discharge the grit. People still do that today.
