The image of those crabs bleeding out is pretty shocking even for someone like myself who hunts my own meat. Are they alive during this process?

They are, yes, and in general they survive the process: https://web.archive.org/web/20130622155603/http://scholar.lib.vt.edu/theses/available/etd-12172003-122534/unrestricted/HurtonThesis.pdf https://web.archive.org/web/20130622155603/http://scholar.li...

If you click the BI link under the image [0] and watch the video they say they're still alive, and that they try to only drain 30% of their blood before putting them back in the ocean. But (paraphrasing) up to 30% don't survive the process and "no one really knows if they even recover down there".

  >no one really knows if they even recover down there It seems like it would be pretty easy to find out. I guess there isn't much motivation to open that can of worms.

    If the answer is a hard no, then you could fully bleed out just 1/3 of the crabs. My naive assumption is that this would help guarantee a stable population, which would probably be beneficial to the bleeders.

  It is tricky to get correct information here, as many of the organization that are related to the conservation of the species are funded by the main producers of LAL based endotoxin tests (and hence bleeders, or procurers of Horseshoe crab blood). At this point, Horseshoe crabs are critical infrastructure in qualityquality control for Pharma and medtech. Source: Co-founded biotech startup in the horseshoe crab space that had to fold.

Crabs have basically insect brains, 10 times less neurons than a bee. Can they suffer? That's an interesting question. It's probably their size throwing you off, would you feel the same about a cricket in that position?

  Horseshoe crabs aren't crabs. They're distantly related, although both are arthropods. Not much brain activity going on there. But honestly pain and suffering are so hard to nail down outside the tetrapods. I'd say the fact that until we started harvesting their blood more sustainably, they pretty much all died is enough of a reason to harvest them more sustainably, regardless of how we define the ability to suffer. They're an important food source for a lot of different animals and we shouldn't be damaging their numbers when we can get the same product without killing them. Also, they like to hump fishermen's boots during breeding season, which is absolutely hilarious and I think well worth preserving the species.

Do you give blood? I do, sometimes I'm in a room with a few other people bleeding red into pouches. I do not find it upsetting, naturally.

  Presumably you aren't abducted by creatures beyond your comprehension who start draining your blood without asking! I don't suspect the crabs have any real understanding of what's happening so the morality of it is ambiguous, but your analogy isn't really analogous.
