This means future growth cannot rely on incremental growth in wild-caught seafood. And while aquaculture has been the primary source of new fish supply in recent years, it has not been able to keep pace with demand. So-called alternative seafood—substitutes for popular fish and shellfish such as tuna, salmon, and shrimp—provides one way to help scale seafood and provide high-end protein. Although still in its early days, alternative seafood shows significant potential across three production options, each with its own advantages: plant-based, fermentation-enabled, and cultivated.
