Abstract
Fecundity was estimated for two pallid sturgeon, Scaphirhynchus albus, from the Lower Mississippi River (LMR). Sturgeon measured 827 and 886 mm fork length, weighed <3.2 kilograms and had 16 237 and 17 810 ova per kilogram of body mass (based on mean ovum density) with total fecundity estimates ranging from 43 357 to 58 913. Ovum size in the two sturgeon was 2.5–3.0 mm diameter. Pectoral fin ray sections showed distinct annuli and spawning bands. The smaller sturgeon was aged at 10 and the larger fish at 12 years. Spawning bands were present and suggest the smaller sturgeon first spawned at age 8 and the larger fish at age 9. When compared to published results, the data representing specimens from more northern populations suggest that pallid sturgeon from the LMR mature at comparable ages but at smaller sizes and have greater gonadal mass. These features and greater fecundity per mass unit (number of eggs per kilogram body weight) suggest that LMR pallid sturgeon populations exhibit greater potential for population growth and recovery than other populations with slower growth and lower fecundity.
