Long-term studies on the reproductive ecology of Smallmouth Bass, Micropterus dolomieu, in the St Lawrence River has allowed us to assess the impact of invasive species.  Specifically, we compare the nesting locations, mating success, and reproductive success during the early 1990s (pre-invasion) with current values today (post-invasion).  We then discuss the potential long-term effects of those impacts on recruitment of smallmouth bass in this system and the fishery for this important species.
