Quick summary: Discover how the global seafood supply chain works—from fishing & aquaculture to processing, logistics, and retail. Learn how tech is transforming the industry!

You pick up a piece of salmon at the grocery store or order shrimp at your favourite restaurant—but have you ever wondered where it actually came from? Was it sustainably sourced? Is it really the species labelled on the package? Was it caught legally? With over 200 million tons of seafood consumed annually, the seafood supply chain is complex, global, and highly regulated. Retailers, restaurants, and consumers demand sustainability, quality, and traceability—but meeting these expectations isn’t easy. 

Studies show that 20-30% of seafood is mislabelled or sourced from illegal, unreported, and unregulated (IUU) fishing operations. 

These questions are more important than ever because seafood fraud, illegal fishing, and unsustainable practices are widespread. For retailers, distributors, and seafood brands, lack of supply chain transparency leads to regulatory fines & shipment holds, lost consumer trust and financial losses Technology is revolutionizing seafood traceability, making it easier than ever to track fish from the ocean to your plate. Keep reading to discover why seafood supply chain transparency is critical for compliance, sustainability, and business success!

The 5 Key Stages of the Global Seafood Supply Chain  

Ever wonder how seafood makes its way from the ocean to your plate? If you’re a retailer, distributor, importer, or seafood brand, the answer isn’t as simple as ‘it’s caught, shipped, and sold.’ 

The global seafood supply chain is a highly complex, multi-step journey involving fishermen, processors, exporters, logistics providers, retailers, and restaurants—all working under strict regulations and rising consumer expectations for sustainability and traceability. 

Stage 1: Harvesting – Wild-Caught vs. Farmed Seafood 

This is where it all begins—the moment seafood is either caught from the wild or farmed through aquaculture. 

Wild-Caught Seafood 

  • Commercial fishing vessels head out to oceans, rivers, and lakes to catch species like tuna, cod, and shrimp. 
  • Common fishing methods include trawling, long-lining, and pole-and-line fishing. 

If your seafood comes from unverified sources, you could be importing illegally fished products—a compliance nightmare! 

Farmed (Aquaculture) Seafood 

  • Fish, shrimp, oysters, and mussels are raised in controlled environments. 
  • This accounts for over 50% of the world’s seafood supply. 

Stage 2: Processing & Quality Control 

Once seafood is harvested, it must be processed quickly to maintain freshness and quality. 

What Happens at This Stage? 

  • Sorting & grading for size, species, and quality. 
  • Cleaning, gutting, and filleting for preparation. 
  • Freezing, smoking, or packaging for transport. 

Implement blockchain-based traceability to verify handling & processing logs

Stage 3: Global Distribution & Logistics  

This is where things get tricky—because seafood is highly perishable and must be kept at optimal temperatures during transport. 

The Cold Chain Breakdown 

  • Step 1: Seafood is loaded onto refrigerated trucks or blast-frozen for air & sea freight. 
  •  Step 2: It’s shipped across international borders under strict regulations. 
  •  Step 3: It arrives at distribution centers, wholesalers, or foodservice providers. 

Stage 4: Retail, Foodservice & Consumer Access 

Once seafood reaches supermarkets, restaurants, and online retailers, consumers expect fresh, safe, and traceable products. 

Where Seafood Goes Next 

  • Retail stores & supermarkets sell fresh, frozen, and canned seafood. 
  • Restaurants & hotels source seafood in bulk from distributors. 
  • E-commerce platforms offer direct-to-consumer seafood delivery. 

Use QR codes on packaging so consumers can trace seafood back to its origin. 

Stage 5: Compliance, Sustainability & The Future of Seafood Supply Chains 

 Regulations are getting stricter. FDA seafood safety laws, and IUU fishing restrictions mean retailers and suppliers must prove full traceability. 

The Rising Pressure for Sustainability 

  • Consumers demand sustainable seafood (MSC, ASC, Fair Trade). 
  • Businesses must document supply chain transparency to avoid legal risks. 
  • AI & blockchain technology are helping improve end-to-end traceability. 

Whole Foods Market ensures all seafood is responsibly sourced & traceable—driving consumer loyalty and sales. 

Ensure supply chain audits to stay compliant with global regulations. 

The global seafood supply chain is complex, highly regulated, and constantly evolving.

Key Challenges in the Global Seafood Supply Chain  

The seafood industry is a massive global market, but behind every fresh fillet at a restaurant or frozen shrimp at a supermarket lies a highly complex supply chain. And with complexity comes risk—from fraud and mislabelling to food safety failures and compliance challenges. 

 For retailers, distributors, and seafood brands, failure to address these risks can mean: 

  • Lost revenue from spoilage, delays, and supply chain inefficiencies. 
  •  Fines and legal action due to non-compliance with international regulations. 
  • Damaged reputation from selling mislabelled or illegally sourced seafood. 

Lack of Traceability Leads to Fraud, Illegal Fishing, and Mislabeling 

Many seafood products change hands multiple times before reaching consumers. Without a transparent tracking system, it’s easy for: 

  • Seafood fraud (swapping cheap fish for premium species) to go undetected. 
  • Illegal, Unreported, and Unregulated (IUU) fishing to infiltrate supply chains. 
  • Mislabelled seafood to be sold to consumers, leading to legal consequences. 

Studies show that 20-30% of seafood worldwide is mislabelled, with cheap fish like pangasius often sold as more expensive species like cod. 

Some Farms Use Unsustainable Feed Sources, Antibiotics, or Poor Environmental Practices 

While aquaculture (fish farming) provides nearly 50% of the world’s seafood, not all farms operate sustainably. Issues include: 

  • Feeding farmed fish with wild-caught fish, contributing to overfishing. 
  • Overuse of antibiotics, leading to environmental and health concerns. 
  • Pollution from overcrowded fish farms, harming marine ecosystems. 

A shrimp farm in Southeast Asia found to be using illegal antibiotics, can lead to an EU import ban on their products. 

If Seafood Isn’t Processed and Frozen Quickly, It Can Spoil Before It Even Leaves the Facility 

Seafood is highly perishable delays in gutting, filleting, freezing, or packaging can cause: 

  •  Rapid bacterial growth, making seafood unsafe to eat. 
  •  Financial losses from wasted product. 
  •  Quality degradation, leading to lower consumer satisfaction. 

A salmon processing plant in Canada can lose an entire day’s catch due to a power outage that delays freezing. 

Poor Temperature Control Leads to Financial Losses and Food Safety Risks 

The seafood supply chain relies on cold chain logistics—any break in temperature control can: 

  • Cause spoilage, resulting in financial losses. 
  •  Fail food safety inspections, leading to shipment rejection. 
  •  Increase the risk of foodborne illnesses, damaging brand reputation. 

A seafood distributor shipping lobster from Maine to Europe can suffer huge monetary losses when refrigeration units fail mid-transit. 

A Shipment That Sits on the Dock Too Long Can Lose Its Freshness and Value 

Delays at ports, customs, and distribution centres can reduce the quality and market value of seafood. 

  • Even a few hours of exposure to improper temperatures can degrade seafood. 
  • Frozen seafood that thaws and refreezes suffers in texture and taste. 

A tuna shipment from Southeast Asia can be held at a port for 48 hours due to paperwork issues, rendering the fish unsellable. 

Border Regulations and Paperwork Delays Can Hold Up Products Until They’re No Longer Usable 

Seafood is one of the most regulated food industries, requiring: 

  • Import/export documentation (FDA, etc.). 
  • Sustainability certifications (MSC, ASC, Fair Trade). 
  • Customs declarations to verify legality and traceability. 

 An EU seafood retailer will need to destroy 5,000 kg of shrimp because their DDS (Due Diligence Statement) is incomplete. 

Global Seafood Buyers Want Proof of Sustainable Sourcing 

Consumers want to know where their seafood comes from—but most retailers don’t provide enough information. Brands that fail to demonstrate sustainability risk losing customers to competitors who do. 

Whole Foods Market can increase seafood sales by 30% by offering QR code tracking for sustainably sourced fish. 

Mislabelling Leads to Brand Reputation Damage & Regulatory Fines 

Seafood mislabelling is a huge problem worldwide, leading to: 

  • Fines and lawsuits for food fraud. 
  •  Erosion of consumer trust in brands & retailers. 
  • Legal action from regulatory bodies (EU, FDA, etc.). 

A sushi restaurant chain in the U.S. can be fined millions of dollars after DNA tests reveals that 70% of its fish is mislabelled.

Sustainable Fishing: Protecting Oceans While Feeding the World 

Sustainable fishing ensures that seafood is harvested responsibly, allowing fish populations to replenish naturally while protecting marine ecosystems. It prioritizes ethical fishing methods, reduced bycatch, and habitat conservation to prevent overfishing and maintain ocean health for future generations. 

  • Eco-friendly techniques like pole-and-line fishing, selective netting, and regulated quotas help maintain species balance. 
  •  Sustainability certifications (MSC, ASC, Fair Trade) ensure consumers and businesses are sourcing responsibly. 
  •  Technology-driven traceability guarantees seafood is legally and ethically sourced, preventing illegal, unreported, and unregulated (IUU) fishing. 

Sustainable fishing isn’t just an environmental responsibility—it’s a business necessity as consumers and regulators demand ethical sourcing.
