As far as I can tell, “3-8 billion killed fish” figure indeed refers to caught fishes, not to farmed fishes (following the links it comes about from the classic 3 trillion / year estimate; http://fishcount.org.uk/published/std/fishcountstudy.pdf). I think that this part of the article is misleading; the relevant number would be the total count of fishes living in farms at any given time, as well as the number of farm slaughters.
I don’t think that’s right. Half the fishes sold to humans for consumption are farmed, but if I understand correctly, a lot of caught fishes are used as feed in farms. Those fishes used for feed will also be relatively smaller and therefore more numerous. So I expect it to indeed be an order of magnitude error.

I thought the same; but nowadays, with half of fish being farmed, it can be an error, but not an order of magnitud error.
