Notropis cahabae | Cahaba Shiner

The Cahaba Shiner is restricted to the middle Cahaba River and the Locust Fork, both in Alabama. CFI propagated these fish for the EPA to be used in toxicology studies. Studying responses to toxins on imperiled and presumably more sensitive species as opposed to the common, hardy species often used in laboratory situations makes sense. We were also able to study the reproductive biology of these rare fishes. We found that Cahaba Shiners deposit their eggs in fine vegetation. The eggs resemble a mucus-like mass, and like the Cape Fear Shiners, larvae hatch premature with no pigment or eye development.  It takes several days for these funky little larvae to finish developing and swim around.
