Age, Growth, and Status of Shortnose Sturgeon in the Lower Ogeechee River, Georgia
Shortnose sturgeon (Acipenser brevirostrum) were monitored as part of continuing studies in the Ogeechee and Canoochee rivers adjacent to Fort Stewart, Georgia, during 1999 and 2000. Over 13,000 net-meter h soak time and 1,700 person h of effort were expended; short (27.5-m) experimental gill nets were a satisfactory sampling gear. Retention of externally mounted telemetry tags was poor (mean = 80 d), and spawning habitats were not located. The population, ranging from ages 3 to 14, was estimated at 147 individuals. Growth equation parameters and rates of mortality were similar to those...
