Summary
Diets were quantified in 282 age-0 sturgeon (15-120 mm) from four reaches of the Missouri River, none of which were pure pallid sturgeon. Prey items in the stomach were identified in the laboratory under microscope to taxonomic order and life stage (larvae, pupae, where appropriate), and counted. Consumption percentage (prey weight in the gut as a percentage of body weight) was measured to assess fullness.
