Seafood mislabeling in Honolulu, Hawai´i
Seafood mislabeling misleads consumers about the abundance of commercially harvested and cultured species, hinders consumer choice, and allows overfished and threatened species to reach the marketplace. Despite the importance of seafood in local culture and in the tourist-driven economy of Hawai´i,...

Seafood mislabeling misleads consumers about the abundance of commercially harvested and cultured species, hinders consumer choice, and allows overfished and threatened species to reach the marketplace.

Here, we use mitochondrial DNA barcoding to investigate patterns of seafood mislabeling in restaurants, groceries, and sushi bars in the greater Honolulu area.
