description | Increased education of consumers can be an effective tool for conservation of commercially harvested marine species when product labeling is accurate and allows an informed choice. However, generic labeling (e.g., as white fish or surimi) and mislabeling of seafood prevents this and may erode consumer confidence in seafood product labels in general. We used DNA barcoding to identify the species composition of two types of convenience seafood (i.e., products processed for ease of consumption): fish fingers (long pieces offish covered with bread crumbs or batter, n = 241) and seafood sticks (long pieces of cooked fish, n = 30). In products labeled as either white fish or surimi, four teleost species were present. less than 1.5% offish fingers with species-specific information were mislabeled. Results of other studies show substantially more mislabeling (e.g., > 25%) of teleost products, which likely reflects the lower economic gains associated with mislabeling of convenience seafood compared with whole fillets. In addition to species identification, seafood product labels should be required to contain information about, for example, harvesting practices, and our data indicate that consumers can have reasonable confidence in the accuracy of the labels of convenience seafood and thus select brands on the basis of information about current fisheries practice. El incremento del nivel educativo de consumidores puede ser una herramienta efectiva para la conservación de especies marinas explotadas comercialmente cuando el etiquetado del producto es preciso y permite una elección informada. Sin embargo, el etiquetado genérico (e.g., como pescado blanco o surimi) y la identificación incorrecta de mariscos evita esto y puede erosionar la confianza del consumidor respecto a las etiquetas de productos marinos en general. Utilizamos códigos de barra de ADN para identificar la composición de especies de dos tipos de mariscos de preparación rápida (i.e., productos procesados para facilitar el consumo): dedos de pescado (piezas largas de pescado cubiertas de migas de pan o masa, n = 241) y varas de pescado (piezas alargadas de pescado cocido, n = 30). En productos etiquetados como pescado blanco o surimi, se encontraron cuatro especies de peces teleósteos. Menos de 1.5% de los dedos de pescado con información de la especie estaba identificado erróneamente.
