Nemo effect

Machine-translated from the Spanish article

The Nemo effect is a term recently adopted in the jargon of biologists, ecologists and, in general, any specialist in the biological sciences. It refers to the Pixar film "Finding Nemo" and is used to describe cases in which populations of exotic species commonly kept as pets develop and spread from individuals (the founders of such a population) that were deliberately released (usually fish, amphibians and reptiles) outside their native range (historical or current) into ecosystems that are not part of their natural distribution area, regardless of the economic and ecological consequences for human populations, ecosystems, habitats and other species. The reasons for such behavior may vary, whether out of ignorance, irresponsibility or whim.
