Introduction of non-native fish species

The introduction of non-native fish species is a growing concern in aquatic ecosystems worldwide. Many non-native species are introduced intentionally for sport fishing or as pets, while others are unintentionally introduced through ballast water or aquaculture escapees. Non-native fish species can disrupt local food webs, spread diseases, and outcompete native species for resources. They may also have other negative impacts, such as altering water chemistry and habitat structure. Conservation efforts aim to prevent the introduction of non-native species and control their spread, but once established, removing them may be difficult or impossible.
