I'm not sure this question is actually on-topic for this site: clearly, from a culinary point of view, fish is considered to be meat. It's only from various cultural and religious points of view that fish are seen as some sort of exception to the flesh of animals definition.– Marti Sep 8 '14 at 18:03.'ve heard one of the reasons fish is allowed on Fridays in Lent is because fish do not receive the breathe of life through their nostrils, meaning they are not considered living animals. Other cultures could have similar ideas.
