Fish and seafood are used as ingredients in almost every cuisine, even land-locked ones.
Owing to religious restrictions on meats, fish became a popular food in European cuisines during religious fasts. This survives in the tradition of “fish on Fridays” in English-based cuisines.
Nowadays, concerns about fish and seafood include sustainability, and proper labelling to ensure authenticity of what consumers think they are paying for.
