I don't know, but I do know that vegetarians don't eat fish. If you do eat fish, but no mammal/bird flesh, you're a pescotarian.

WTF? Of course it's meat! The real question is whether or not bugs are meat. I don't even really consider them alive in the same sense as other animals.

Would you eat a bug, StarOcean?

Yes   YES

Well, if a "vegetarian" eats fish but not meat for moral reasons or for the environment, he/she is kind of daft since the fishing industry is incredible destructive to the environment and fish breeding farms have horrible conditions for the fish as well the ocean as a biotope (it kills everything under and around it).
So that leaves health benefits, which are true for many kinds of fish, but not all fish is healthy and some meat is just as good for you as most fish, so that's pretty much also down the crapper.
In my opinion; there are no good arguments for eating fish and not meat if you from any logical standpoint. Choosing to do it because you don't like the taste or texture or what have you is something else, and may be more viable as an excuse, but these are the exact reasons people usually don't like fish...

Anything that takes oxygen from air or water through lungs or gills have meat to me. Might be a few exceptions.

Insects don't have lungs but they have lunglike breathing so they might have meat too.

But plants or coral that do photosynthesis don't have meat.

Nutrition wise, it's good for your brain and less fattening compared to pork and beef, but it's still meat.

So if I "Slaps around a bit with a large trout", I'm actually beating them with my meat? Freaking IRC had a secret language... 😒

The confusion is that, in English, meat is categorized into poultry, fish, and meat (mammals). So fish meat is fish, bird meat is poultry, but mammal mea
Vegetarians don't eat fish. They eat only plant based food. An Ovo-lacto-vegetarian eats egg and dairy products, but no meats. The distinction between vegetarianism and veganism is that vegetarianism is a duet, veganism is a way of life. A vegan is a vegetarian who doesn't wear wool, leather, or purchase products from brands that harm animals.

I know "vegetarians" who eat fish (agree, doesn't make sense). I also know some who will eat eggs (which is borderline the same thing).

Vegetarian is just as grey a definition as most people's dietary habits. Vegans are the only true no-hurt-animals diet. But that requires medication to be done right because your body requires animal protien of some form to (B12 I think, if I remember correctly) to keep eyesight, etc.

Personally, I don't see the difference in killing an animal for food or a plant. They are both living things. Just because one doesn't have eyes or one you perceive as somehow a higher life form - its still destroying life to prolong the life of another. That's just nature, its how life is defined. The only concern we should have is how we raise and kill life we need to consume. That should be humane and not cruel. Now, if you're vegetarian because that is your actual healthy diet plan (i.e. you think eating meat is unhealthy and causes fatness), then cool that at least has an arguable stance IMO. I disagree, but I can understand the logic. Not wanting to hurt animals (life) is simply not the way nature / life is designed.

Eat rocks. The only way to make sure you dont consume products of sth that is or was alive.
