🐟 Cell-Based Seafood

Cultivated Fish, Shrimp & the End of Aquaculture Suffering

The Scale of the Problem Cell-Based Seafood Could Solve

Wild-caught and farmed seafood represents one of the largest sources of animal suffering on Earth. By weight, more fish are killed for food each year than all other farmed animals combined — with estimates ranging from 0.8 to 2.3 trillion wild fish killed annually, plus hundreds of billions more in aquaculture.

How Cultivated Seafood Works

Cultivated (cell-based) seafood uses the same fundamental technology as cultivated meat:

  1. Cell extraction: A small biopsy of cells is taken from a donor fish or shrimp — a minimally invasive, one-time procedure
  2. Cell culture: Cells are grown in bioreactors with nutrient-rich culture media, multiplying rapidly
  3. Scaffolding: For structured products (fillets), cells are grown on edible scaffolds that give the product its texture
  4. Harvest: The resulting product is molecularly identical to conventional seafood — same proteins, omega-3s, and flavor compounds
The welfare case: Once cell lines are established, no new fish need to be harmed for production. The billions of animals currently suffering in aquaculture and wild-catch fisheries could be replaced by a small number of donor animals in controlled laboratory conditions.

Leading Companies and Products

🦐 Shiok Meats (Singapore)

Pioneering cultivated shrimp; shrimp cells are particularly well-suited to cultivation due to their biology. First cultivated shrimp tasting in 2019; working toward commercial scale.

🐟 BlueNalu (USA)

Focused on whole-muscle fish products; demonstrated yellowtail, mahi-mahi, and bluefin tuna prototypes. Partnership with major Japanese seafood distributor Mitsubishi.

🐡 Wildtype (USA)

Cultivated salmon; raised $100M+ in funding; focus on sushi-grade salmon with authentic texture. One of the most advanced US companies in regulatory pathway.

🦑 Avant Meats (Hong Kong)

Cultivated fish maw (swim bladder) and grouper; targeting Asian premium seafood markets where wild-caught prices are extremely high.

🐠 ViaCyte/Finless Foods (USA)

Bluefin tuna cultivation; one of the highest-value and most welfare-concerning wild fisheries — a critical target for cultivated seafood.

🦞 Cultured Decadence (USA)

Cultivated lobster and crab; targeting the premium crustacean market where welfare concerns (boiling alive) are significant.

Regulatory Status 2025

United States

The FDA and USDA share regulatory oversight of cultivated meat and seafood. Upside Foods and Good Meat received FDA clearance for cultivated chicken in 2023 — establishing the regulatory pathway. Cultivated seafood companies are advancing through FDA consultation processes; first approvals expected 2025–2027.

Singapore

Singapore was the first country to approve cultivated meat for sale (Good Meat chicken, 2020) and has positioned itself as a global hub for alternative protein regulation. Several cultivated seafood companies are using Singapore as their regulatory launch market.

European Union

Novel Food Regulation applies to cultivated seafood; the process is more complex than in the US or Singapore, with timelines potentially extending to 2027–2028 for first approvals.

Challenges Ahead

Cost: Cultivated seafood remains expensive — current costs are far above conventional seafood. Scale-up of bioreactor capacity and optimization of culture media (particularly reducing the need for fetal bovine serum) are critical cost reduction priorities.
Texture: Replicating the complex muscle structure of fish fillets is technically challenging. Current products often work best in minced or formed applications (fish cakes, nuggets) rather than whole fillets.
Consumer acceptance: "Lab-grown" associations create perception challenges; industry is exploring framing around "cultivated" and "ocean-kind" seafood.
Omega-3 advantage: Cultivated seafood could be engineered to maintain or enhance omega-3 fatty acid content — a key nutritional reason people eat seafood — by optimizing culture media, potentially matching or exceeding wild-caught nutrition.

The Welfare Bottom Line

Cell-based seafood represents one of the most promising long-term pathways to dramatically reducing aquatic animal suffering. Given the enormous scale of fish and crustacean suffering in both wild capture and aquaculture, even partial market penetration by cultivated seafood could have welfare impacts exceeding most other interventions combined. Supporting this technology — through consumer interest, investment advocacy, and policy support — is one of the highest-leverage actions available to animal welfare advocates.
