Horseshoe Crabs

Identifying Spawning Habitat: Maryland DNR is seeking your help in identifying shoreline used as horseshoe crab spawning habitat in our State of Maryland. While fishing, if you notice horseshoe crabs spawning upon the shoreline, please document the location (GPS coordinates if possible). For horseshoe crabs in the Chesapeake Bay please contact Marek Topolski at 410-260-8263 or by email at mtopolski@dnr.state.md.us. For horseshoe crabs in Maryland coastal bays please contact Steve Doctor at sdoctor@dnr.state.md.us or 410-213-1531.

Horseshoe Crab Tags: If you should find a tagged horseshoe crab, record the tag number, location of observance, and condition of animal, and report this information online - Horseshoe Crab Resighting Form. It is not necessary to remove the tag. Those who report a tagged horseshoe crab may receive a reward.
