Model input and output data supporting modeling the Silver Carp metapopulation connection between the Mississippi and Illinois River

September 14, 2026

This data release contains input data, estimated demographic parameters, movement probabilities, and simulated population outputs for a Silver Carp (Hypophthalmichthys molitrix) metapopulation model. The model explores the importance of the interjurisdictional connection between the Illinois and Mississippi Rivers, with a focus on developing strategies to reduce the risk of an invasion to the Great Lakes. Input data include posterior distributions for length-weight relationships, von Bertalanffy growth curves, von Bertalanffy growth curve standard deviations, female length-maturity relationships, and movement (transition) probabilities. Output data contain the final simulated population distributions under different management scenarios.
