One glimmer of hope is this is in Monterey - where the Moneterey Bay Aquarium is. I understand they have a few programs directed at conservation efforts. Let's hope they take this up.
First of all the rocky botom can offer some kind of protection against trawls.
And second, is not clear if this octopus are edible. I can't identify the species with this video. Maybe Graneledone but I'm not sure. The much smaller squat lobster (Munida? Munidopsis?) in the video can be deceptive but the octopus look very small to me. We could be talking about a small animal of only 10cm of mantle length (body minus tentacles). Probably not valuable enough to risk the fishing material and spending fuel on it.
