Abstract
Many shoal habitats in the Piedmont of
Georgia have been destroyed by reservoir construction,
and the remaining are still threatened. To understand
relations between aquatic biota and habitat conditions
in shoals, we estimated fish densities in shoals differing
in physical characteristics (e.g. size and bed material)
throughout a 50 km reach of the upper Flint River
(Meriwether, Pike, Upson, and Talbot counties) during
2001 and 2002. Our surveys show that the Flint shoal
fauna includes five fishes endemic to the Apalachicola
River system, and that abundances of at least three of
the endemic fishes (Halloween darter – Percina sp.,
bluestripe shiner – Cyprinella callitaenia , shoal bass –
Micropterus cataractae) vary substantially among
shoals. We are using fish abundance and associated
habitat data to build models useful for predicting effects
of flow alteration on endemic fishes in the upper Flint
River.
