Thane A. Militz's opinion article: "The 'Nemo Effect': Perception and reality of Finding Nemo's impact on marine aquarium fisheries"
examines the impact of such motion pictures on the demand for the animal stars as pets. Generally the article underlines the need for more and better data, not only documenting the trade, but more importantly for data on the status of targeted populations and catch data to form the base for fishery and wildlife trade management.
With the studied data being restricted to import data to the US, the authors find no evidence for a raise in demand for wild-caught A. ocellaris following the film. However, it is likely that studying import data to Europe, including the captive bred A. ocellaris obtained largely from US based breeders, would have provided a different picture.
