Exactly, fish is meat, it's flesh. I understand preference, I don't understand a weird moral equivalency that doesn't count animals that live underwater as animals.
People on this thread have talked about fish being 'free and wild' but the vast majority of fish and shellfish people eat is farmed.
I wouldn't eat farmed salmon, the only fish I eat is wild and line caught, and I don't eat it often because good fish, as with good meat is very expensive. I buy mackerel and sardines as regular fish. I don't buy salmon or bass or other than treat time.
Occasionally other fish such as sea trout in season and John Dory and turbot Cornish catch.
Prawns, brown shrimp are the native prawn and delicious and sustainable, mussels are generally rope-grown and a bit flabby, clams are reliable and oysters should obviously be only eaten in the R months when natives are in season. Langoustine are from northern waters around the British Isles and are lovely, if not brutal on the thumb.
I don't actually think the vast majority of people really think about where their food comes from.
And I love cod but it's problematic in terms of stock, haddock and hake are great firm white fish caught in our waters.
As an island nation we don't love fish as much as we should, mainly going for the farmed stuff, most of our excellent catch is sold to mainland Europe, we have an amazing cold water stock that we should enjoy.
But flabby farmed salmon and imported prawns seem to be the choice.
And I haven't even spoken about cephalopods who are generally as intelligent and as social as your average dog and are highly social.
So yes, I don't understand pescitarianism.
