VIDEO: Delaware Bay Horseshoe Crab Population Sought by Researchers

Posted:

Researchers are looking for answers with regard to determining a horseshoe crab's survival in the delaware bay.
Regulators with the Atlantic States Marine Fisheries Commission say they need to get a firmer grip on how many horseshoe crabs die in association with medical harvesting.
The crabs are harvested for their blue blood, which contains coagulogen, a chemical that can be used to detect bacteria in medical products.
Nearly 50,000 crabs are harvested each year for biomedical use,
And that's not taking into account commercial harvesting by fisherman for bait.
Just in 2014 alone, the commercial harvest grew to $1.8 million dollars from $400,000 dollars in 2004.
