The public is invited to join the Delaware Department of Natural Resources and Environmental Control (DNREC) for a virtual public hearing conducted by the Atlantic State Marine Fisheries Commission (ASMFC) from 6 to 8 p.m. on Thursday, Sept. 8. The hearing will gather public input on the ASMFC Horseshoe Crab Draft Addendum VIII, which considers adopting the changes to the Adaptive Resource Management (ARM) Framework recommended in the 2021 ARM Framework Revision and allowing its use in setting annual bait harvest specifications for Delaware Bay-origin horseshoe crabs.

The ASMFC, of which Delaware is a member state, initiated Draft Addendum VIII in January 2022, after it accepted the 2021 Revision of the ARM Framework and Peer Review Report for management use. The 2021 ARM revision utilizes the best-available science and includes improvements to the ARM framework’s population models for horseshoe crabs and red knots. It incorporates more sources of horseshoe crab removal data, including mortality due to the biomedical industry and commercial discards from other fisheries. The ARM framework is an ecosystem-based approach to manage the Delaware Bay horseshoe crab population to ensure enough eggs to support the migratory red knot population during their annual spring stopover.

Information about the ASMFC virtual public hearing is available from the DNREC events calendar at de.gov/dnrecevents. Or, the public may access detailed instructions to join, how to provide comments and download the Draft Addendum VIII from asmfc.org.

Horseshoe Crab Management Effectively Supports Red Knot Population

While this year’s spring shorebird migration has ended in Delaware, with the shorebirds embarking for their Arctic nesting grounds fueled for their journey after consuming abundant horseshoe crab eggs, the horseshoe crabs continue to spawn along the shores of Delaware Bay. The annual spring phenomenon of nature features the ecological relationship between migrating shorebirds that feast on horseshoe crab eggs to help sustain their long-distance migration from their wintering grounds as far away as southern South America to their nesting grounds in the Arctic – a one-way trip that can span more than 9,000 miles for some shorebird species.

Shorebirds more than double their body weight during their brief stopover each spring along Delaware Bay, feasting on the abundant supply of horseshoe crab eggs from an increasing horseshoe crab population managed under the Atlantic States Marine Fisheries Commission’s (ASMFC) Adaptive Resource Management (ARM) framework. The ARM framework is an ecosystem-based approach that uses the best-available science to manage the Delaware Bay horseshoe crab population to ensure enough eggs to support the migratory red knot population during their annual spring stopover. Under ARM management, the Delaware Bay horseshoe crab population has steadily increased over the last decade to an estimated 31.3 million crabs, comprising 21.9 million males and 9.4 million females. More information on the ASMFC ARM can be found at asmfc.org.

Delaware allows a limited harvest of 162,136 only male horseshoe crabs – representing less than 1% of the scientifically-estimated total Delaware Bay horseshoe crab population, with the harvested crabs used as bait for Delaware’s commercial conch fishery. Horseshoe crab harvest in the state is not allowed until June 8 after migrating shorebirds have left to avoid disturbing the birds during their stopover. Delaware does not have a horseshoe crab biomedical collection fishery that exists in other states, including New Jersey.

The red knot is listed as a threatened species under the federal Endangered Species Act and as an endangered species by the State of Delaware. The estimated red knot population that stops and feeds each spring along Delaware Bay has remained steady over the previous 10 years, at approximately 40,000 to 50,000 birds annually as reported in the Red Knot Stopover Population Estimate for 2021 produced by the U.S. Geological Survey (USGS), in cooperation with the DNREC Division of Fish and Wildlife and the New Jersey Division of Fish and Wildlife.

The USGS stopover population estimate is based on extensive, scientific red knot surveys. Numerous factors affect the red knot population in addition to horseshoe crab egg availability, including habitat loss, human disturbance, predator dynamics and climate change at wintering, migration and nesting areas. More information on shorebird research and monitoring, including the U.S. Geological Survey red knot stopover population report, is available at https://de.gov/shorebirds.

The DuPont Nature Center managed by the DNREC Division of Fish and Wildlife located near Slaughter Beach provides great views from the center’s large deck overlooking the Mispillion Harbor of a variety of wildlife, including seasonally spawning horseshoe crabs and migrating shorebirds, including the red knot. More information is available from the DuPont Nature Center at de.gov/dnc, where the center’s Mispillion Harbor Cam can be accessed for live views of wildlife visiting the area.
