Re: NANFA-- fish behavior at dams, trip report,

A lot of stream fish do small (or large) migrations for spawning. Sturgeons
migrate for spawning, which leads to some of their problems with dams (like
the Alabama sturgeon). Even some darters move upstream for spawning, like
the Slackwater darter (as much as 5 km apparently). Creek chubs would seem
to be an ideal candidate for some spawning migration because of their
relatively elaborate spawning rituals, and because they're one of our
ultimate stream fishes.
