I'm super surprised that they even bother. I would have thought this were a simple birth->death captivity cycle. Though I wouldn't be surprised if this were only out of necessity; perhaps the crabs simple don't thrive in captivity.
Or perhaps we have less of an ethical standard for the animals we farm just because we like the taste of their milk on our taste buds.
Unfortunately, as far as animal ethics go, it feels like progress is so slow that even etching out a comment is a waste of time. It's like being for women suffrage in the 1700s; people just roll their eyes at you, and you hope the people 100 or 200 or 300 years down the road wake up because it's not happening in your lifetime.
Then again, I admit it's no simple feat for us humans to have gone from bone and fur and tribal technology to a global technological civilization in just thousands of years. And every awakening and enlightenment is always obvious and taken for granted in hindsight. There's probably even a good benefit to having such glacially evolving ethics: taking a bad fork in the road can kill a civilization.
