Plant-based for seafood are being produced using a range of ingredients and processes. The growth of the sector has largely been spearheaded by start-ups, many of which claim to be providing an ethical and sustainable alternative to farmed and wild-caught seafood. As the sector evolves, it is now also beginning to attract the attention of corporate food producers. Currently, plant-based seafood is not widespread globally, with the bulk of producers being based in high-income countries. Most consumers can source traditional seafood at lower prices than plant-based products. If this business model does not change, this niche sector  may struggle to penetrate the mass market.
