UK-based Marine Conservation Society’s Good Fish Guide uses scientific information from reputable and peer-reviewed sources to generate ratings for over 140 different species. Wild capture ratings are reviewed annually and farmed ratings are reviewed every three years, and updated ratings are released on a biannual basis. Rating updates from 2022 can be found here.
