A Wave of Change in Dining
Ocean ecosystems are under pressure from overfishing and climate change. As a result, plant-based seafood alternatives are emerging as a solution. Companies are creating realistic substitutes for favorites like salmon and shrimp. These products appeal not only to vegans but also to consumers who want to reduce their environmental impact.
“This is more than a trend. It’s a shift in how we think about food and our oceans,” says culinary sustainability expert Dr. Lena Moreau.
Market Growth Is Rapid
The global plant-based seafood market was valued at about USD 600 million in 2024. Moreover, it is projected to grow at a compound annual growth rate of 8.6 percent from 2025 to 2030.
North America leads with a 37.7 percent revenue share. Health-conscious shifts toward flexitarian and vegan diets drive this growth. Meanwhile, Europe is growing at a projected 9 percent CAGR, driven by ethical concerns and sustainability policies.
These alternatives use peas, soy, algae, and legumes to mimic the taste and texture of real seafood. In addition, they help reduce problems like mercury contamination and overfishing.
Leading Companies in the Field
Good Catch Foods is a pioneer in plant-based seafood. They offer tuna, crab cakes, fish burgers, and fillets made from a six-legume blend. Products are available at Whole Foods, Amazon, and in foodservice settings.
“Creating plant-based seafood that tastes like the real thing is challenging, but the demand is clear,” says GoodCatch spokesperson Maya Lin.
Other innovators include OmniFoods, which produces the Golden Fillet for vegan fish and chips, and Mimic Seafood, which uses tomatoes and algae for tuna alternatives. However, the name Ocean’s Harvest appears to be a misnomer; no prominent plant-based brand uses this exact name.
High-End Restaurants Embrace Sustainability
Upscale restaurants are joining the plant-based seafood trend. In New York, Eleven Madison Park operated as fully plant-based from 2021 but reintroduced meat and seafood in 2025. Nevertheless, it continues to feature creative vegan dishes. Dirt Candy offers sophisticated plant-based seafood that mimics the textures of real fish.
London has several fully vegan fine-dining restaurants. Plates is the city’s only Michelin-starred plant-based restaurant. In addition, Gauthier Soho and Studio Gauthier are leading the trend. These venues use fermentation and 3D printing to create kelp caviar and banana blossom “fish.” OmniFoods partners with London eateries to create vegan twists on classics like fish and chips.
Plant-Based Seafood in Retail and Beyond
The trend is also reshaping retail and consumer habits. In Germany, a vegan shopping basket is now five percent cheaper than one with meat, dairy, and seafood. Furthermore, innovations include 3D-printed salmon and algae-based shrimp. Companies like Wildtype Foods are developing cell-based seafood for purity and sustainability.
In the U.S., plant-based food sales reached $8.1 billion in 2024. Importantly, seafood alternatives contributed significantly to this total.
A Sustainable Future for Seafood
As awareness grows, more consumers are seeking ways to protect ocean health and improve personal wellness. Plant-based seafood offers an alternative to overfishing and pollution. Therefore, with projections reaching USD 1.5 billion by 2035, plant-based seafood is not just a trend—it is the future of dining.
