I recommend this study for all importers of ornamental fish!!!
Why? It might have a serious impact on our fish industry due to strict quarantine regulations that can be implemented in your country!
This study reports the results of a nationwide parasitological survey that was conducted from 2019 to 2022 to investigate the potential introduction of monogenean parasites into India via the ornamental fish trade. A total of 619 individual exotic ornamental fish representing 27 teleost species from nine families were collected from major aquaria markets and examined for monogeneans. 26 monogenean species from 12 known genera were detected and identified in 17 of the 27 fishes examined.
