- Summary
- * Invasive species have caused substantial ecological and economic problems globally. • In New Zealand a number of invasive fish species occur and are, in some places, particularly abundant. The acknowledged epicentre and only formally defined containment area for invasive koi carp (an ornamental strain of Cyprinus carpio) in New Zealand is located in the North Island in the Lower Waikato River Basin. • Eutrophic conditions combined with a temperate climate and connected shallow riverine lakes and wetlands provide ideal conditions for the proliferation of this and other invasive fish such as the brown bullhead catfish (Ameiurus nebulosus) and goldfish (Carassius auratus).
