This is a super shortsighted view. Every life form in the ocean plays a role in the ecosystem and catastrophic damages like this have first and second order effects all over the place.
I'm pretty sure my point was the only reason for harvesting snow crab is that it is lucrative for these fisherman, yet snow crab isn't an important staple of any diet, so there was absolutely no compelling societal reason to fish them into population collapse or extinction, not even greed. My suspicion is the majority of the product here was wasted, rotted and discarded, so we should really put pressure on commercial fishers in the US and abroad to find another way to support themselves in order to stop them from killing everything in the ocean rather than romanticize a way of life that is economically and ecologically unsustainable, such as is inexplicably done for ranchers, nor should we frame them as sympathetic victims of climate change.
