Two Echinodorus species were produced in masses in Peruvian Amazonia for international aquarium plant trade from the 1950s to 1990s. In the beginning of this time period production was large-scale including field cultivation, but to the end of the period production faded rapidly. Decline in production was a consequence of rapid development of aquarium plant cultivation in Asia, U.S.A. and Europe. Nowadays aquarium plant production involves in vitro propagation and other highly sophisticated methods, and thus re-establishing large-scale aquarium plant production in Amazonian countries may not be economically viable. However, due to high biodiversity in Amazonia, the area may have a significant role in new aquarium cultivar prospecting.
