Various Phenotypes and Genetic Characteristics of Five Imported Ornamental Fish Species

Recently, as the demand for ornamental fish has increased due to the expansion of the ornamental fish market, various species are being imported, but the possibility of new species or species that have not been reported is increasing. In particular, there are concerns about problems such as the introduction of diseases and ecosystem disturbance, so the need for systematic quarantine of ornamental fish is increasing. Currently, ornamental fish, as designated quarantine items, are under quarantine in accordance with the Aquatic Organism Disease Control Act. However, due to a diverse range of breeds and dispersed packaging, quarantine takes a long time, and there are concerns that this may lead to death. To solve these problems, it is important to establish a list of ornamental fish breeds and basic research. In this study, we aim to improve the speed and accuracy of quarantine by visually observing and genetically confirming the relationship between the phenotype and genotype of ornamental fish.
