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

8th generation crab fishing here. Two reasons: space as they would eat each other and it takes to long to shed their shells to grow to get to a good size. When they shed their shell they come out like jelly but slightly bigger and they have to harden up again and that only tends to happen once a year maybe twice in colder water. In the late 90s my father caught a cock (male) brown crab that was one of the biggest caught in the channel. We named it Clarence and gave it to Plymouth aquarium where it sat in one of the tanks. It was over 20inches across the shell with claws the size of boxing gloves and they reckoned it was well over 30 years old. Be impossible to farm that.

They are cannibalistic and territorial as previously commented. Crab farming exists differently vs fishes, they are held in individual ‘hotel boxes’ in a RAS setup (closed loop recirculating water).

Some animals will only “love each other very much” under very specific conditions. Sometimes those conditions are either impossible or very, very expensive to recreate in captivity. Or we just haven’t quite worked out what the conditions are yet. Sometimes it’s cheaper or easier for our corporate overlords to just let workers die instead.

I heard that when Europeans first came to North America, lobster were so plentiful that the lobster would wash up onto the beach in piles up to 2 ft high. But since lobster was considered the cockroach of the sea, it was relatively unpopular to eat.

Interestingly, lobstering is more like farming. Most lobsters will live entirely off bait and be caught hundreds of times and released before they are considered keepers. One study estimated that bait made up for 80% of what wild lobsters eat.
