<p>Predicted Silver Carp relative condition factor (Kn) across locations in the Upper Mississippi River based on data collected during 2021–2023.</p>

A Kn value of 1 indicates that the fish’s weight matches the expected weight for its TL, whereas values above or below 1 indicate a better or poorer body condition, respectively. Points and error bars represent predicted mean Kns and their associated 95% confidence intervals, derived from generalized linear mixed models for the three river sections: Above L&D 19, Pooled Reach, and Open River. <i>P</i> values from the analysis of variance indicate whether the mean Kn values significantly differed across locations within a river section.

The mean Kn values between locations that do not share a lowercase letter within a river section were significantly different at the <i>α</i> = 0.05 level based on pairwise comparisons.</p>
