Generic names and mislabelling conceal high species diversity in global fisheries markets (2018)
Journal Article
Cawthorn, D., Baillie, C., & Mariani, S. (2018). Generic names and mislabelling conceal high species diversity in global fisheries markets. Conservation Letters, 11(5), e12573. https://doi.org/10.1111/conl.12573

Consumers have the power to influence conservation of marine fishes by selectively purchasing sustainably-harvested species. Yet, this power is hindered by vague labelling and seafood fraud, which may mask market biodiversity and lead to inadvertent...
