In order to make plant-based and cultivated seafood as tasty and nutritious as conventional products, we need to understand the properties of those products. GFI’s Phylogenetic Index of Seafood CharactEriStics (PISCES) aggregates data characterizing conventionally-produced seafood. As part of our Sustainable Seafood Initiative, PISCES is designed to inform and accelerate alternative seafood development. Read more about the goals of this resource. For instructions on how to use this tool, please see the PISCES user guide. See something missing? Suggest new cell lines or papers for us to add!
