What Is Sustainable Seafood?
On February 16, 2025 By newsroom Topic: Food Guide
Sustainable seafood refers to fish and shellfish harvested or farmed in ways that ensure the long-term health of marine ecosystems, minimize environmental damage, and allow populations to replenish naturally. Here’s a guide to understanding the key concepts, labels, and advice to make eco-conscious seafood choices.
Key Methods of Harvesting Seafood
Wild-Caught Seafood
- Challenges: Overfishing, unintended species capture (bycatch), and habitat damage caused by large nets or dredging.
- Sustainable Practices:
- Pole-and-Line Fishing: Catches fish individually, minimizing bycatch and overfishing.
- Troll Fishing: Uses baited lines to catch fish selectively.
Farmed Seafood
- Benefits: Controlled environments reduce exposure to pollutants like mercury and ensure consistent levels of nutrients like omega-3s.
- Concerns: Crowded conditions can lead to disease and antibiotics usage, which may impact surrounding waters.
- Best Practices: U.S.-raised fish often follow stricter pesticide and antibiotic regulations.
Fishing Techniques: Pros and Cons
- Pole-and-Line Fishing
- Pros: Reduces bycatch and supports sustainable populations.
- Cons: Labor-intensive and often more expensive.
-
Example: Wild Planet Skipjack Wild Tuna (100% pole-and-line caught).
-
Longlines and Nets
- Pros: Efficient for large-scale harvesting.
- Cons: High risk of overfishing and unintended capture of endangered species.
Understanding Labels and Certifications
Organic Fish:
- There is no official USDA organic certification for seafood in the U.S.
- Wild-caught fish cannot be organic due to lack of controlled environments.
Seafood Watch:
- Provides a trusted guide for sustainable seafood options.
Farmed vs. Wild-Caught:
- Farmed options are often more affordable, with consistent quality.
- Wild-caught options are favored for their natural environment but can cost more.
Tips for Choosing Sustainable Seafood
- Prioritize Local Options: U.S.-farmed fish typically adheres to stricter sustainability standards.
- Consider Omnivorous Fish: Tilapia and catfish, which feed on algae or insects, reduce the demand for fish-based feed that contributes to overfishing.
- Explore Alternatives: Lesser-known fish like Arctic char or barramundi are often more sustainable and less costly than popular options like salmon or shrimp.
- Check Sustainability Guides: Use tools like Seafood Watch to identify sustainable species and avoid overharvested ones.
