Fish fillets from the lab

“Will we soon be eating reactor-grown fish fillets, Dr. Rakers?”

We’ve made great progress in that direction. We’ve been working on fish cells since 2008 and have been producing cell-based fish since 2020. It is an important option for feeding the world’s growing population. In the laboratory, fish is made from adult stem cells that we only have to extract once from an animal and then multiply in a bioreactor. Our cultured product isn’t exposed to any environmental toxins and helps to protect the natural animal populations, which are greatly threatened by overfishing. Moreover, it can be produced in precisely the quantities that people actually consume and therefore reduces the amount of waste fish. However, several years of development time will still be needed before we can sell cell-based fish fillets whose appearance, taste, and cooking properties are indistinguishable from those of conventional fish.
