Re: level of effort, some brief googling tells me that there has been some interest in breeding octopuses for food, but it’s been quite difficult, particularly handling the larvae. BBC claims the current state-of-the-art is a promise that farmed octopus will be on the market in 2023.
Update 2024: that octopus farm still isn’t operational due to widespread opposition, but it’s not canceled yet either.
