This article is mainly about how fish species are introduced to different bodies of water all over the world. These species are not native to the area and effect the biodiversity of the body of water, fresh or salt. These new species take over ecosystems because they do not have natural predators in their new environment. They also tend to grow larger and live longer because of this. With these new dominant species, other smaller, native species are killed off and plant life is killed off or overgrown and macroinvertibrates die off or overpopulate the water depending on what plant and animal life is killed off.

This is another article that generally talks about non native species being introduced to countries all over the world and that most of the species introduced have impacts on the ecosystems they are taking over. The main cause of the introduction of non native species is aquaculture. Aquaculture fisheries often have fish escape from the farms and get into natural bodies of water. The fish species either survive or don't and the ones that do survive, not only survive but thrive in their new habitats because mainly there are no natural predators. Carp are mainly the most damaging species because they can live in poor quality water and survive in almost any body of fresh water. The Grass Carp and the Silver Carp are under particular concern. Fish farms farm exotic foreign species because they are usually the type of fish that is most demanded.
