First post on the forum so be gentle.
TL;DR: The Spanish company Nueva Pescanova is planning to farm octopus and begin selling it on the market in 2023. They intend to sell 3,000 tons of farmed octopus per year, which amounts to several hundred thousand octopuses. This is concerning given that octopuses are highly intelligent animals; there are no released standards for how the octopuses are going to be kept and raised, nor for how they will be slaughtered. There doesn't seem to be much in the way of coordinated action against this yet.

Assuming ten pound octopi, that's ~600,000 octopi farmed and killed every year. I think that an octopus is ~30% likely to be as morally relevant as an adult human (with wide error bars, I don't know as much about the invertebrates as I'd like to), so this is pretty horrifying to me.
Oh, I'm sorry for being unclear! The second phrasing emphasizes different words (as and adult human) in a way I thought made the meaning of the original post clearer.
