Why has the White Crappie sometimes been classified as an invasive species outside its native range?
Answer
Ability to establish large, self-sustaining populations
When the White Crappie is introduced into aquatic ecosystems outside its native range, it can sometimes be designated as an invasive species due to its ecological success in those new areas. The primary reason for this classification stems from its high degree of adaptability and robust reproductive capability. This allows the species to effectively establish large, self-sustaining populations even in environments that might be challenging for other native fish species. Their capacity to thrive, particularly given their tolerance for slightly lower water quality compared to some other sunfish, means they can outcompete or dominate resources, leading to ecological imbalance.
