The catch of the day: The shortcomings of promoting sustainable seafood consumption in Peru

open access: yesConservation Science and Practice, Volume 8, Issue 5, May 2026.
This study investigates the meaning and application of “catch of the day” in Peru by analyzing 233 news articles and genetically testing 43 fish samples from restaurants. Results show that media frequently use the term as a vague marketing phrase, while genetic testing reveals a 60% mislabeling rate. These findings suggest that “catch of the day” lacks
