> fish are way less intelligent than farm animals

There is no concrete evidence of this. A lot of sea creatures, including fish, have skin cells that can create polarized light and some seem to have developed communication systems with pulses of polarized light.

Just the other day it was found that some fish can pass the mirror test, didn't you see that?

The prevailing theory is that ratio of brain mass to body mass is more telling than the absolute size of the brain. Fish may fare worse on this metric but I suspect it's just an area where we have very little understanding yet.

Being vegetarian or vegan is not so hard. It is one of many fundamental changes that society should pursue to avert the current ecological crisis and mitigate species loss.

A bit weird nitpicking when you yourself make an insubstantial claim about some "prevailing" theory. I think we can both agree that reducing meat consumption is the right thing to do, it's just sometimes to convince people you need to show some leeway.

Why don't you go check it out yourself?

check what? You posted some links that explain a metric which was theorized to measure intelligence. That wasn't what I requested source for (it's a theory). I asked for a source that says this theory is the prevalent theory.

Btw I never made any comment about fish's brain size, I said they're generally less intelligent than farm animals, which wikipedia agrees with, fits the brain ratio theory too: https://en.wikipedia.org/wiki/Fish_intelligence#Brain

Thanks for derailing the conversation anyway, at the end, there is no such thing as a fish
