if crab fishing is so dangerous (think Deadliest Catch) why aren’t there crab farms like we have with fish?

Crabs are cannibalistic, and territorial. If we did have a crab farm it would pretty much have to be as big as the area we’re already fishing for them in.
Edit: Weird that one of my most voted comments is about crabs being dicks. I’m not a professional crabber, though my uncle was a crab fisherman for a few seasons.
Couple things, we could cage crabs, but we would need to find a way to let them feed, mate and burrow. Crabs also need vastly different environments as they grow from larvae to full grown crabs, they’re migratory, so it would be very expensive to have a large farm that provides their needs.
There are crab farms, for certain crabs, they don’t produce nearly enough to make fishing obsolete. King Crabs, Dungeness crabs and snow crabs aren’t so friendly.
