A market survey was performed on caviar from Romania and Bulgaria, two of the last range states of critically endangered sturgeons threatened by poaching and illegal trade. Twenty-seven samples were collected between April 2011 and February 2012, including two samples of Bulgarian farm caviar bought in an Austrian fish shop. Mitochondrial sequences of the cytochrome b gene and microsatellites were used for species identification. Ten samples were in agreement with the species code on their CITES labels, but four samples were mislabeled, six samples were counterfeit and four samples were offered as 'wild origin,' ignoring the fishing bans in place. At least one sample was upgraded from a lower priced species to a more expensive species. These results demonstrate the weakness of sturgeon protection in these Member States of the European Union and key range states. Therefore, we recommend intensifying conservation and enforcement efforts, including also DNA testing of caviar in containers with apparently correct CITES labels.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
