Luciobarbus graecus is a ray-finned fish species in the family Cyprinidae. It is here placed in Luciobarbus following the IUCN, but that genus is very closely related to the other typical barbels and perhaps better considered a mere subgenus of Barbus.

Scardinius is a genus of ray-finned fish in the family Cyprinidae commonly called rudds. Locally, the name "rudd" without any further qualifiers is also used for individual species, particularly the common rudd. The rudd can be distinguished from the very similar roach by way of the rudd's upturned mouth, allowing it to pick food items such as aquatic insects from the surface of the water with minimal disturbance.

J. Stewart Smith was a British New Zealand man known for releasing several species of invasive freshwater fish into the country's waterways. A self-proclaimed Communist, Smith's goal was to introduce the coarse fishing of his childhood to New Zealand, which originally only had small native galaxias and introduced trout to fish for. Over the course of several decades, Smith would smuggle in fish and breed them in his garage in Massey, before releasing the offspring into rivers and lakes all over North Island. Due to his actions, the ecology of New Zealand's freshwater ecosystems has been permanently altered.
