Once the bleeding is completed, the crabs are released far from where they were caught so that they aren't scooped up and re-bled before they have enough time to regenerate what has already been lost. Work, though, continues in the lab, where the powder-blue blood has to be spun in a centrifuge so that the desired elements can be isolated. The LAL, once siphoned off and bottled, is worth about $15,000 per quart.
