Another random look-in at twitter: https://twitter.com/HNTurtledove/status/973628196275945472.

For the Twitterless: Turtledove references a fossil species of salmon, then explains its something he referenced in an upcoming story, then clarifies that we don't see a live one in the story. Another user provided a link to an extinct species, and HT confirms that it is the one he's thinking of.

We know that one of the unpublished Jefferson stories is entitled "Something Fishy", so I'm betting that's the one to which he's referring.
