At the species-interaction level, invasive species can change the behavior, and ultimately the survival of certain native species. Notably, the invasion of the Great Lakes by the Round Goby (Neogobius melanostomus) in the early 1990s has raised questions regarding the impact they have on native Smallmouth Bass (Micropterus dolomieu), which occupy the same habitat. Round Gobies (RG) are known to aggressively evict young Smallmouth Bass (SMB) from shelter habitats and epibenthic substrate, which could lead to reduced growth, increased predation risk, and ultimately, population decline. I quantified the behavior of young SMB, in terms of shelter use, in the presence of invasive Round Gobies in comparison to native Logperch (Percina caprodes) (LP) with a replicated experiment set up in small pools with PVC pipe shelters. Time spent in shelter was measured using video footage. In the presence of Round Gobies, with or without a predator present, SMB spent little to no time in the shelter (0.019 and 10.09 percent, respectively). An increase in shelter use by the SMB occurred in the presence of LP and when in the presence of a predator and no other species. SMB were unable to remain in the shelter in the presence of Round Gobies because they were aggressively evicted, which is an indication that behavior of young-of-the-year Smallmouth Bass is negatively affected in the presence of Round gobies.
