Body of Abstract (250 words or less): Since the mid-1990's, horseshoe crabs (Limulus polyphemus) have been the basis of significant commercial fisheries for bait (eels and whelks) and biomedical use (extraction of blood for Limulus amoebocyte lysate). We compared the sex ratio, size structure, and condition index of the horseshoe crab population in Delaware Bay, New Jersey before and after the expansion of the fishery in the mid-1990's to evaluate some possible impacts of the fishery on reproductive biology. Both sexes have experienced population declines, but females have declined more rapidly than males. Consequently, the sex ratio in the spawning population in Delaware Bay has become more skewed towards males, which is consistent with the preferential harvesting of females for the eel bait fishery. We did not observe significant changes in the size structure of the population, despite the reported preference of the bait and biomedical industries for larger animals. Similarly, we saw no temporal shift in the carapace condition index, suggesting that fishing was not selective for "younger" individuals within the population. We recommend continued monitoring of the carapace condition index as a means of detecting new recruits into the adult population.
