The ocean crisis driving a seafood revolution

Can plant-based seafood feed 10 billion people?

The world’s appetite for fish is growing faster than the ocean can provide. By 2050, nearly 10 billion people will require food, and wild fish populations cannot keep up with the increasing demand.

Research supported by The Good Food Institute reveals that plant-based fish products and lab-cultivated seafood are emerging as viable solutions to this looming crisis. These alternatives could help meet growing demand without further depleting marine ecosystems already pushed to their limits.

The scale of the problem

Nearly 90 percent of marine fisheries are already fully exploited or overfished. Commercial fishing operations now cover more than 55 percent of the ocean’s surface. That is four times more area than all the land used for agriculture combined.

Three billion people currently rely on the ocean for food and jobs. Yet even with perfect management, there is a ceiling on how many fish can be sustainably harvested each year.

“Building a better food system will require a diversity of solutions,” the researchers emphasize.

Climate change compounds the crisis

Rising ocean temperatures are pushing fish populations toward the poles, leaving tropical waters increasingly empty. Some regions could see a 40 percent drop in potential seafood catch by mid-century.

The fishing industry itself contributes to the problem. Fuel-intensive vessels and aquaculture feed production release significant greenhouse gases. This creates a cycle that accelerates the very warming that threatens fish stocks.

Innovation on the horizon

Several companies are already scaling production of seafood alternatives. In Chicago, Aqua Cultured Foods is developing fungi-based seafood using a special fermentation process to create whole-muscle cuts like scallops, shrimp, and tuna.

In Canada, Konscious Foods produces plant-based sushi meals made with locally grown ingredients such as quinoa, carrots, and tomatoes. The company recently received a $5 million investment to expand production and create over 40 new jobs in British Columbia.

Benefits beyond conservation

Alternative seafood offers multiple environmental advantages. By reducing overfishing and bycatch, these products give wild fish populations time to recover. They also minimize habitat destruction and antibiotic use compared to traditional aquaculture.

“Alternative seafood is the future of sustainable seafood,” the researchers conclude. “An ocean of opportunity awaits.”
