Brown trout (Salmo trutta) introductions that have been studied in New Zealand include predation of native galaxiids and their exclusion from stream habitat, potential reduction in insect and other invertebrate populations that may lead to reduced grazing, increased algal biomass, and other trophic effects, as well as facilitation of the evolution of anti-predator behavior of some invertebrates.
