For nearly 20 years, scientists have been working to figure out why horseshoe crabs are the best bait for eel and whelk and to produce a substitute.
Dr. Nancy Targett, dean of the University of Delaware's College of Earth, Ocean and Environment and director of Delaware Sea Grant says that work is now bearing fruit. Scientists recently unveiled a new, synthetic bait that is highly attractive to eel and whelk, yet uses only a fraction of the horseshoe crabs previously needed in the industry.
"We developed an artificial bait that's affordable and more easily stored," Target said. It's a win-win."
The artificial, composite bait her research team developed uses a small amount of ground horseshoe crab, compounds in brown seaweed, food-grade chemicals such as baking soda and citric acid, and tissue from an invasive species, the Asian shorecrab.
The addition of the Asian shorecrab allows researchers to reduce the amount of horseshoe crab tissue needed from one-half a female crab to one-sixteenth.
In addition, it's no longer only female crabs that are used as bait.
"We found that it didn't matter whether we used female or male horseshoe crab tissue in the artificial bait," Targett said.

The Mid-Atlantic Fishery Management Council has scheduled a series of scoping hearings to gather public input for a proposed action to protect unmanaged forage species.
The proposed action would consider a prohibition on the development of new, or expansion of existing, directed fisheries on unmanaged forage species in the Mid-Atlantic until adequate scientific information is available to promote ecosystem sustainability.Read more...
