Fecundity of the Pallid Sturgeon

Abstract Fecundity was estimated for a 17,110-g, 41-year-old, female pallid sturgeon Scaphirhynchus albus taken from the upper Missouri River. The mass of mature eggs weighed 1,952 g, which represented 11.4% of total body weight. Using a mean of 87 eggs/g, we estimated total fecundity at 170,000 eggs for this fish.
