The introduction of rainbow trout (Oncorhynchus mykiss) to an enclosure within a Great Lakes tributary in Ontario caused a 35% decline in stonefly abundance relative to areas without rainbow trout. Stonefly populations were adversely affected by both predation and disturbance, which led to emigration.

Laboratory

In a laboratory experiment, Lithobates spectabilis tadpoles altered their behavior in the presence of visual and chemical cues from the invasive predator Oncorhynchus mykiss. In the presence of chemical cues, tadpoles increased their refugia use and in the presence of visual cues they increased their distance from the visual cue.
