Abstract
The family Atyidae includes over 500 freshwater shrimp species, with ornamental genera Caridina and Neocaridina widely traded for aquariums. From 2008-2024, 26 million individuals of 37 species were imported into Korea, mainly from Taiwan, Indonesia, and Thailand. Imports rose steadily after 2016, dominated by Neocaridina heteropoda, Neocaridina denticulata, Caridina multidentata, Neocaridina davidi, and Caridina cantonensis, comprising 94% of individuals. Although none were CITES-listed, eight Caridina species are threatened (CR/EN) under IUCN. N. davidi is invasive in the U.S. and Japan due to its tolerance and adaptability, and has been found in Germany. Risks include hybridization, disease transmission, and potential ecological disruption if released into the wild. While no ecological damage has yet been reported in Korea, preventive management is needed to avoid escapes and ensure biosecurity in light of increasing imports and ecological risks.
