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

Some crabs are already farmed, notably mud crabs in south asia and hairy crabs in China.
Deep sea crabs aren’t farmed simply because it’s not economically viable. Depending on the species they might take 10 years to reach market size and live hundreds of metres deep, whereas mud crabs can be sold in less than a year.
Also some species are prone to attack each other.

Not really mentioned is it takes a king crab five years to reach harvesting size. For farmed animals this is a pretty long time. For comparison beef cattle are slaughtered at about 18 months – 2 years.

There are many reasons why some animals and plants can’t be grown in a farm set up. Stress on the animal is the main one. Lots can’t handle captive life. Inter fighting is another one. Proper food supply can be an issue as well. Pretty much, at this point, it it can be farmed, it already is being farmed

Dunno about other countries but there are crab and lobster farms here in my country (Vietnam). And it is not rare either. Wild ones are considered better and more expensive, but the majority of crabs supply here comes from farm.

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.
