Lots of cultures don't class fish in with most meats. In traditional Catholicism the rule against meat on Fridays didn't apply to fish and likewise with Japanese Buddhist rules against meat eating. It's sort of like how most people consider tomatoes to be vegetables even though they aren't, scientifically.

Yeah, in 21st century English fish is a meat but it's non-centrally meat so the meaning is clear when you apply Gricean norms.

Woah woah woah, hold up there. Scientifically speaking, a vegetable is the edible part of a plant. Tomatos are vegetables and fruits scientifically. This is like arguing that a square isn't a rectangle! Okay, carry on <3

Having spent the best part of the last 17 years speaking 21st century English, this is a surprisingly strong assertion to me.

Likewise chicken is often not considered 'meat' despite clearly being the flesh of an animal. It's kind of weird, but not as weird as the people who think "a little bit of ham" in a salad doesn't count as meat.

When I was visiting Brazil I met a bunch of people that called themselves vegetarians who would eat chicken and bacon. Turns out "vegetarian" means not eating beef. It led to some pretty funny misunderstandings.

Judism also doesn't consider fish meat for the purposes of Kosher-ness.
