The horseshoe crab has a tendency to fall in population in its distribution area, and in 2004 is defined by the "red directory of chinese species" as an endangered species. The horseshoe crab is an indicator species of the estuary ecosystem, and can reflect the overall health and stability of the coastal wetland ecology. The amoebocyte extract in blue blood of Chinese horseshoe crab can be made into horseshoe crab reagent, which can sensitively detect trace bacterial endotoxin and fungal polysaccharide, and is widely used in clinical medicine, pharmacy, food industry and other fields. The artificial breeding and propagation and release are used for supplementing the population quantity in natural environment, and are important site-moving protection measures for recovering the horseshoe crab resources. At present, proliferation and release of the horseshoe crab mainly take 1-age larvae, but Carmichael et al (2003) obtain that the death rate of the young horseshoe crab with 6 or more ages in the natural environment is obviously lower than that of the young horseshoe crab with 1-5 ages, and the proliferation and release of the young horseshoe crab with 6 or more ages can ensure the effect of scientific release.
