During mesocosm experiments, F. rusticus reduced the abundance of the native snail species Lymnaea stagnalis; when F. rusticus co-occured with Cipangopaludina chinensis (the Chinese mysterysnail), Lymnaea stagnalis was extirpated from the mesocosm.

Faxonius rusticus reduced the number of Faxonius propinquus in an experiement, possibly partly due to predation, as predation by F. rusticus on F. virilis was observed in the experiment and in the field.

Rusty crayfish were highly successful in preying on juvenile lake sturgeon (all crayfish immediately captured a sturgeon). Sturgeon also shifted habitat in response to crayfish, which could make them more vulnerable to fish predators.
