NANFA-- disappearing Southern Red Belly Dace
Sun, 6 Jul 2003 11:34:17 EDT

A few years ago, Bill Flowers showed me a place near Mooresville, Indiana
that had Southern Red Belly Dace. A few collecting trips and traps set overnight
have failed to yield any. The physical changes in that immediate area are
that three beaver dams have appeared and then removed. One dam appears to be
coming back. The area above the stream has been leveled and some street
installed for a housing development.

My questions are:

Is it likely that the entire population is gone? Or is it likely to be
downstream? Or I just have had some unlucky collecting trips?

Did the beaver dams probably effect the population? There are plenty of
chubs and other fish there, though I did not catch any sculpins that were there
with the Dace. What other factors could have caused the population to crash?

Also, if anyone knows the location of another population of SRBD in Indiana,
I would appreciate them sharing it with me.
