Which fish is a common example of a pestiferous fish that negatively impacts native populations?

The common carp is recognized as a pestiferous fish that poses significant threats to native aquatic populations. This species is highly adaptable and can thrive in a wide range of aquatic environments, often outcompeting native fish for resources such as food and habitat. Their feeding behavior, which involves uprooting aquatic vegetation, can lead to habitat destruction and further destabilization of ecosystems. This disruption can have cascading effects on native fish populations, as well as other aquatic organisms that rely on healthy plant life for shelter and breeding grounds.

In contrast, the other fish listed, such as trout, salmon, and catfish, generally do not have the same level of negative impact on native populations as common carp do. These species may actually benefit certain ecosystems or maintain balance in their respective habitats rather than exerting the kind of detrimental influence that is characteristic of common carp.
