The “Shark-Free Ceviche” seal is a benchmark that will certify fish ceviche products that have not been made with protein from elasmobranchs (sharks and rays) or other species threatened with extinction or protected by law in the countries where the seal is implemented. The aim is to inform consumers that the use of the fish species targeted by this initiative is rejected, to differentiate the companies that join the initiative, and thereby discourage their fishing, trade, and consumption. The challenge is to bring commercial allies on board, who often see the initiative as an increase in their operating costs, even though it is not as much as they think. The positive thing is that more companies want to join, and organizations similar to MarViva in other countries are beginning to show interest in partnering with the seal and implementing it.
