Changing Tastes conducted the first ever research into consumer and business decision maker attitudes about animal welfare and antibiotic use in aquaculture. This was done at the request of the Open Philanthropy project. Changing Tastes’ research found that both consumers and purchasing decision makers are concerned about the ways that slaughter practices and the use of antibiotics affect flavor, texture, and quality, and that adopting humane practices can increase the sale of farmed fish and seafood. These findings were presented at the GOAL conference in Ecuador, which brought together the largest aquaculture producers in Latin America and Asia. This work is now beginning to inform the choices of large seafood companies and trade organizations.
