What is it about?
The findings of this study reveal that 1 out of every 3 fish sold in restaurants, fish markets, and supermarkets are mislabeled and do not correspond to their genetic identification. This is a staggering number and raises serious concerns about the accuracy of labeling in the fishing industry.

Why is it important?
In addition to highlighting the issue of mislabeling in the fishing industry, the study also sheds light on the importance of traceability in ensuring the sustainability of our marine biodiversity. Did you know that artisanal fishing provides 1 out of every 2 fish on the tables of Mexicans? This underscores the need for us to take a more holistic approach to manage our marine resources.

Multiple drivers behind mislabeling of fish from artisanal fisheries in La Paz, Mexico
We hypothesize that the level of supply of each species could help explain mislabeling and substitution rates, where species in low supply and high demand could show higher mislabeling rates and rarely be used as substitutes, while species in high supply and low demand could be used as substitutes for the preferred species.
