Effects of environmental variation on timing of spawning and early life-history characteristics of two populations of shoal bass in the upper Chattahoochee River basin

Mike Porta with shoal bass from the Chattahoochee River, Georgia.

Duration

July 2009 - December 2011

Narrative

Since the GA DNR and the NPS began a shoal bass stocking program to restore this fishery to the Chattahoochee River below Morgan Falls Dam in 2003, several studies of varying scales have taken place to better understand the unique population dynamics of this species in this section of the river. However, little has been done to comprehensively understand the factors that will affect the sustainability of shoal bass in its restored state. We are conducting a study to quantify success of the 5-year restoration program and the effects of environmental variation on the timing of spawning and early life history characteristics (age, growth, mortality) of shoal bass in the Chattahoochee River below Morgan Falls Dam and in a tributary (Big Creek).
