How to Choose Sustainable Bluefin Tuna
If you’re committed to making environmentally friendly choices, consider these tips:
Look for Certifications: Opt for Bluefin Tuna that carries certifications like the Marine Stewardship Council (MSC) label.
Choose Farm-Raised Bluefin: While not perfect, farm-raised Bluefin Tuna is a more sustainable option than wild-caught.
Avoid Consuming Juveniles: Eating smaller, younger Bluefin Tuna puts additional pressure on populations.
