These data were compiled to evaluate the potential impact various environmental conditions may have on native fish populaitons through predation. Introduced warm-water sport fishes present a high predation risk for juvenile native fishes, but observations of juvenile native fish surviving and recruiting in some rare cases led us to question what environmental conditions might be responsible for these trends. These data were compiled to allow for a relative comparison of predation effectiveness between a suite of warm-water predators under a variety of environmental conditions. Mean numbers of prey fish surviving in replicated overnight laboratory predation trials were quantified.

The purpose of the data are to evaluate the relative predation effectiveness of a suite of common warm-water introduced fishes in overnight laboratory predation trials. These laboratory data establish a baseline that will assist fisheries managers in evaluating the potential predation impacts warm-water sport fishes may have on native fish populations.
