Population Dynamics of Bowfin in a South Georgia Reservoir: Latitudinal Comparisons of Population Structure, Growth, and Mortality

SEAFWA Journal Volume 1, March 2014

The objectives of this study were to evaluate the population dynamics of bowfin (Amia calva) in Lake Lindsay Grace, Georgia, and to compare those dynamics to other bowfin populations. Relative abundance of bowfin sampled in 2010 in Lake Lindsay Grace was low and variable (mean±SD; 2.7±4.7 fish per hour of electrofishing). Total length (TL) of bowfin collected in Lake Lindsay Grace varied from 233-683 mm. Age of bowfin in Lake Lindsay Grace varied from 0-5 yr. Total annual mortality (A) was estimated at 68%. Both sexes appeared to be fully mature by age 2 with gonadosomatic index values...
