I wonder if people making the association between turbibity/pollution and
blackbanded darter numbers aren't actually making the connection between
slower deeper water and the tendency of such water to appear more
turbid. In 1990, I collected data on fish-habitat relationships in a
stream in South Carolina. There were two darter species in the stream,
blackbanded darters and turquoise darters, Etheostoma inscriptum. I was
looking at the turquoise darters, so I didn't work up the data on the
blackbanded darters. I found blackbanded darters in the lower reaches,
where the water was a bit more sluggish and deeper.
