Iowa Project

Estimating age, growth, and mortality in a tributary-spawning population of Shovelnose Sturgeon using a long-term mark-recapture dataset.

January 2023 - December 2025


Participating Agencies

  • Iowa Department of Natural Resources

This project seeks to utilize an 18 year mark-recapture dataset to overcome challenges with estimating important population parameters for making management decisions for the Shovelnose Sturgeon population that is harvested for caviar and meat in the Mississippi River.
