Horseshoe Crab Project
This tag-and-release research/education project focuses on the population ecology of the horseshoe crab (Limulus polyphemus) in Long Island Sound. Dr. Jennifer Mattei of Sacred Heart University's Biology Department is the principle investigator of this long-term, community wide research project. The Maritime Aquarium participates by tagging and collecting data on horseshoe crabs encountered during field studies and research cruises. It has been recently discovered that migratory shorebird survival is linked to the horseshoe crab's breeding season. Migrating shorebirds consume horseshoe crab eggs, helping fuel their long trip north to breed. In addition, the federally protected loggerhead sea turtle also depends on horseshoe crabs for food. Horseshoe crabs are also important to humans because of a component in their blood that is used to detect bacterial contamination in manufactured drugs and other pharmaceutical products.
By understanding the population dynamics of this species we will be better able to manage their harvest and prevent their extinction. The horseshoe crab population ecology investigation is currently being supported by a grant from the Long Island Sound License Plate Program, managed by the Connecticut Department of Environmental Protection and Sacred Heart University. Other participants include, Project Oceanology, SoundWaters, Bridgeport Aquaculture School, the Peabody Museum and the Connecticut Audubon Coastal Center. To participate in this study, contact Dr. Mattei at 203-365-7577 or matteij@sacredheart.edu

Tagging can usually start 2 hours before and extend to 2 hours after low tide. For those accompanying the TMA staff, we will meet about 4:45 AM to do tagging at Calf Pasture beach. We usually need to park outside the park and walk in the main entrance. Gear to the right, follow the road and gather at the Shea monument at the Coast Guard Auxillary/sailing school area at the southwest corner of the park.
Each participant should bring the following:
• Food and water bring your own please.
• good headlamp or flash light(s) with broad dim light
• pencils
• insect repellent, (midges and mosquitoes are common in most places at these times).
• Waders, hip boots or knee boots, sturdy walking shoes or clothing that can get wet and are appropriate for the weather.
Some find gardening/flooring knee pads a blessing and a sturdy bucket (6 gal. wine or sheet rock compound) great to sit on.
Training for this activity can be done on location, or prior to the activity. There will be two training sessions at the Maritime Aquarium for those who wish to attend on Wednesday, May 14 and again on Saturday, May 17 from 7 to 9 PM. The training will include information on natural history as well as how to tag.
