Consumers and regulators influence conservation of marine finfish by controlling harvest demand and availability. Consumer power to choose sustainably‐harvested species is threatened by seafood mislabeling, which may be a product of fraud or human error. Here we examined the prevalence of mislabeling, and its financial and ecological implications, by compiling and analyzing an international dataset of DNA barcoding studies of marine finfish ( n = 43). On average, DNA‐identified species sold were less expensive (−2.98% ex‐vessel price) and more sustainable (+3.88% IUCN status) than species listed on their label; thus, mislabeling had a net positive impact on the conservation status of sold species. However, ecological impacts of some frequently mislabeled taxa were potentially severe, suggesting eco‐conscious consumers may want to avoid certain genera. Mislabeling may be reduced by increasing traceability and identification of seafoods, particularly at points in the chain‐of‐custody beyond ports, where the majority of mislabeling occurred.
