Which Fish and Shellfish Should You Avoid Buying?
Navigating the seafood market can be tricky. In general, you should avoid buying imported shrimp due to environmental concerns and potential human rights abuses, Chilean Sea Bass due to overfishing, and farmed Atlantic salmon due to questionable farming practices.
Introduction: Navigating the Complexities of Seafood Choices
Choosing sustainable and ethically sourced seafood can feel like navigating a minefield. With complex supply chains, varying fishing regulations, and confusing labeling practices, consumers often struggle to make informed decisions. Which fish or shellfish would you avoid buying? is a question with multiple layers, encompassing environmental sustainability, human rights, and even personal health. This article, guided by expert insight, aims to demystify the seafood selection process, empowering you to make choices that align with your values and protect our oceans.
The Environmental Impact: Overfishing and Destructive Practices
One of the primary reasons to avoid certain fish and shellfish is the detrimental impact of their harvesting on the marine environment.
- Overfishing: When fish are caught faster than they can reproduce, populations dwindle, disrupting the entire ecosystem.
- Destructive Fishing Practices: Bottom trawling, for example, involves dragging heavy nets across the seafloor, destroying coral reefs and other vital habitats.
- Bycatch: The unintentional capture of non-target species, such as dolphins, sea turtles, and seabirds, is a significant concern.
Human Rights Concerns: Exploitation in the Seafood Industry
Beyond environmental concerns, the seafood industry is plagued by human rights abuses, particularly in certain fisheries and processing plants.
- Forced Labor: Workers may be subjected to debt bondage, physical abuse, and extremely poor working conditions.
- Trafficking: Individuals are sometimes trafficked into the fishing industry and forced to work against their will.
- Unsafe Working Conditions: Fisheries are often dangerous environments, with workers facing the risk of injury or death.
Sustainable Alternatives: Empowering Consumers
Fortunately, there are many delicious and sustainable seafood options available. By making informed choices, consumers can support responsible fisheries and protect our oceans.
- Look for Certifications: The Marine Stewardship Council (MSC) label indicates that a fishery meets rigorous sustainability standards.
- Consult Seafood Guides: Organizations like the Monterey Bay Aquarium’s Seafood Watch provide recommendations on the best and worst seafood choices.
- Buy Local: Supporting local fisheries often means shorter supply chains and greater transparency.
Top Offenders: Fish and Shellfish to Avoid
Based on the above concerns, here are some specific fish and shellfish that you should generally avoid buying if possible:
- Imported Shrimp: Often farmed in environmentally damaging ways and associated with human rights abuses.
- Chilean Sea Bass (Patagonian Toothfish): Heavily overfished and often caught using destructive fishing methods.
- Farmed Atlantic Salmon: Can have a negative impact on wild salmon populations and contribute to pollution.
- Orange Roughy: Extremely long-lived and slow-growing, making it vulnerable to overfishing.
- Shark: Many shark species are threatened or endangered due to overfishing and finning.
- Certain Types of Tuna (e.g., Bluefin Tuna): Some tuna populations are severely depleted.
Understanding Seafood Labeling: Decoding the Details
Navigating seafood labeling can be confusing. However, understanding the key information can help you make more informed choices.
- Country of Origin: Indicates where the fish was caught or farmed.
- Fishing Method: Provides information about how the fish was caught (e.g., trawling, longlining, pole and line).
- Farming Method: If the fish is farmed, the label may indicate the type of farming system used (e.g., open net pen, recirculating aquaculture system).
- Certifications: Look for labels from organizations like the MSC, Aquaculture Stewardship Council (ASC), and Best Aquaculture Practices (BAP).
The Role of Aquaculture: Addressing the Challenges
Aquaculture, or fish farming, can be a sustainable way to meet the growing demand for seafood. However, it also presents challenges.
- Environmental Impacts: Some aquaculture practices can pollute waterways, damage habitats, and contribute to disease outbreaks.
- Feed Sources: The use of wild-caught fish as feed for farmed fish can exacerbate overfishing.
- Sustainable Practices: Recirculating aquaculture systems and integrated multi-trophic aquaculture (IMTA) are more sustainable alternatives.
Common Mistakes: Avoiding Pitfalls in Seafood Selection
Consumers often make mistakes when selecting seafood. Here are some common pitfalls to avoid:
- Assuming all imported seafood is bad: While many imported seafood products raise concerns, some are sustainably sourced.
- Relying solely on price: Cheaper seafood may be associated with lower environmental or labor standards.
- Ignoring certifications: Look for reputable certifications to ensure sustainability.
- Not asking questions: Don’t hesitate to ask your fishmonger about the origin and harvesting methods of the seafood they sell.

Frequently Asked Questions (FAQs)
What makes imported shrimp so problematic?
Imported shrimp is often farmed in mangrove forests, which are destroyed to make way for shrimp ponds. This habitat destruction contributes to climate change and loss of biodiversity. Additionally, the industry is often associated with forced labor and other human rights abuses.
Why is Chilean Sea Bass considered unsustainable?
Chilean Sea Bass, also known as Patagonian Toothfish, has been heavily overfished in the past. While some fisheries are now better managed, it’s important to choose MSC-certified options to ensure sustainability. Illegal fishing remains a significant concern.
What are the environmental concerns associated with farmed Atlantic salmon?
Farmed Atlantic salmon can pollute waterways with waste and chemicals. It can also escape into the wild, competing with and interbreeding with wild salmon populations. Sustainable aquaculture practices are crucial to minimize these impacts.
Is it always better to buy wild-caught fish than farmed fish?
Not necessarily. While some wild-caught fisheries are well-managed and sustainable, others are overfished. Similarly, some aquaculture practices are more sustainable than others. Certification labels and seafood guides can help you make informed choices.
What does the MSC label mean?
The Marine Stewardship Council (MSC) label indicates that a fishery has been independently certified as meeting rigorous sustainability standards. This means that the fishery is well-managed, minimizes its impact on the environment, and doesn’t contribute to overfishing.
How can I find out which seafood is sustainable in my area?
The Monterey Bay Aquarium’s Seafood Watch program provides regional guides that recommend the best and worst seafood choices based on sustainability criteria. Many local organizations also offer similar resources.
What is bycatch, and why is it a problem?
Bycatch refers to the unintentional capture of non-target species during fishing. It can include dolphins, sea turtles, seabirds, and other marine animals. Bycatch can have devastating impacts on these populations, threatening their survival.
What are some simple steps I can take to make more sustainable seafood choices?
Read up on which fish or shellfish would you avoid buying and then:
- Consult seafood guides.
- Look for certifications.
- Ask your fishmonger questions.
- Choose local seafood when possible.
Are there any specific types of tuna that are more sustainable than others?
Skipjack tuna, particularly when caught using pole and line methods, is generally considered a more sustainable choice than bluefin tuna. Albacore tuna can also be a good option, depending on the fishing method and location.
What is “fish fraud,” and how can I avoid it?
Fish fraud involves mislabeling seafood, often substituting a cheaper or less sustainable species for a more expensive one. To avoid fish fraud, buy from reputable sources, ask questions, and be wary of unusually low prices.
Is it ethical to eat seafood if I am concerned about animal welfare?
The ethics of eating seafood are complex. Fish can feel pain and experience stress, but their cognitive abilities are different from those of mammals. Supporting sustainable fisheries and choosing farmed seafood raised with humane practices can help minimize harm to marine animals.
Where can I find more information about sustainable seafood?
Many organizations offer resources on sustainable seafood, including the Monterey Bay Aquarium’s Seafood Watch, the Marine Stewardship Council, and the Aquaculture Stewardship Council. You can also find information on government websites and in academic journals.
