Banks Lake National Wildlife Refuge is a 1,640-ha refuge consisting of 405 ha open water (Banks Lake) and 1,235 ha of cypress swamp, marsh, and uplands located in southern Georgia. Fishes from Banks Lake, a system with problematic densities of both indigenous and nonindigenous aquatic vegetation, were collected during eight sampling periods in open water habitats from 1992 through 2003 to evaluate assemblage and sportfish dynamics. Stability and persistence analyses indicated that the fish assemblage was stable and persistent over time, though catch per unit effort of assemblage members...

The Okefenokee Swamp is the largest freshwater wetland in the United States; however, population dynamics of the fish assemblage within the swamp are poorly understood. Fish surveys from 1992-2001 indicate that two species, bowfin (Amia calva) and flier (Centrarchus macropterus), are the numerically dominant taxa of the eastern portion of the swamp, representing over 88% of all fishes collected. Results indicated that the fish assemblage was persistent and stable in terms of constancy of dominant species presence and their abundances. The four most abundant species, bowfin, flier, chain...
