Horseshoe crabs are used as bait to fish for [[eel]]s (mostly in the United States) and [[whelk]]. However, fishing with horseshoe crab is temporarily forbidden in [[New Jersey]] (moratorium on harvesting) and restricted to only males in [[Delaware]]. A permanent moratorium is in effect in South Carolina.<ref>{{cite web|url=http://www.dnr.sc.gov/marine/mrri/acechar/specgal/crabshoe.htm|title=Horseshoe crab|work=SC DNR species gallery|accessdate=6 June 2011}}</ref> The eggs are eaten in parts of Southeast Asia and China.<ref>{{Cite web|author=大西一實|title=Vol.56 食うか食われるか?|url=http://www.kaikyokan.com/cgi/fish3/56.htm|work=あくあは〜つ通信 |accessdate=2008-04-18 }}</ref>▼

A low horseshoe crab population in Delaware Bay is hypothesized to endanger the future of the [[red knot]]. Red knots, long-distance migratory shorebirds, feed on the protein-rich eggs during their stopovers on the beaches of New Jersey and Delaware.<ref>{{cite news |url=http://www.ens-newswire.com/ens/mar2008/2008-03-26-093.html |title=Red knots get to feast on horseshoe crab eggs |publisher=[[Environment News Service]] |date=March 26, 2008 |accessdate=January 19, 2011}}</ref> An effort is ongoing to develop adaptive-management plans to regulate horseshoe crab harvests in the bay in a way that protects migrating shorebirds.<ref>{{cite web|last1=October 26, 2011|title=Critter Class Hodge Podge (Horseshoe crabs and Wooly Bears)|url=http://wildlifecenter.org/sites/default/files/cam_archives/26OCT_Hodge-Podge.pdf|publisher=The Wildlife Center|accessdate=9 March 2015}}</ref>▼
