How Horseshoe Crabs Are Saving Us from Healthcare-Associated Infections

Global: There are some newer tests that may replace at least the bacteria-detecting role of LAL and TAL, which are not made from horseshoe crab blood. One is recombinant factor C — synthetic version of Factor C, a clotting factor in horseshoe crab blood, from cloned DNA. Another uses human blood. It’s called the monocyte activation test (MAT), also known as the in-vitro pyrogen test, and it may eventually detect non-endotoxin bacteria that horseshoe crab blood can’t reveal. Scientists continue to develop those methods so they can be more reliable and widely used, while also searching for other alternatives. download the pdf.

Climate Change Plays Unlucky for Horseshoe Crabs

US: Horseshoe crab populations are declining across the entire East Coast, from Maine to Florida, and are triggering a domino-effect among the larger animals that prey on them. Already, researchers are observing marked decreases in shore bird populations, especially the red knot bird and loggerhead sea turtles, two species that commonly feast on the crabs. Human activity, from overfishing to population booms along shorelines, have been blamed for recent drops in the number of American horseshoe crab (Limulus polyphemus). A new study in the journal Molecular Biology suggests that climate change may also play a significant role. download the pdf.

From Cod to Conch- How the Fisheries Have Shifted Focus Over The Past Twenty-Five Years

Massachusetts: Jimmy Morgan fished from the Mary and Verna for almost forty years out of Menemsha. In July 2008, there tired fisherman was featured in the magazine, which has covered recreational and commercial fishing regularly through the years. Way back when Janet Messineo used to wait tables in Vineyard restaurants, calamari was never on the menu. And sushi? Who’d ever heard of sushi? And twenty-five years ago, when this magazine began, fishermen could still harpoon swordfish in Vineyard waters. The great collapse of cod stocks had not happened. Few of us had even heard of global warming, let alone anticipated its potential to devastate our lobster fishery. Who thought conch fishing would become a major industry? Who thought “trash” species like the horseshoe crab would need a management plan for protection? Yes, a great deal has changed in the past quarter century: what we harvest from the sea, what we eat of it, what we do with the rest, what’s still out there, and what is no longer out there. download the pdf.

Fishermen Feud Over Horseshoe Crab Protection

Massachusetts: Ancient crabs spawn during full moon in May, June. Among all the species taken by fishermen in this part of the world, horseshoe crabs have, until now, enjoyed a dubious distinction: they were the only ones targeted while in the act of reproducing. The easiest way for many to catch them was to walk the beaches at the times of the full and new moons in May and June and simply pick them up as they came into the shallows to spawn. Not anymore though. As of this year, new regulations will stop the practice. For five days around each full and new moon, they will be left undisturbed as they sow future generations of themselves. A new minimum size limit also has been established. download the pdf.

Last summer, Melissa Alvarez, a senior project biologist with the Army Corps’ New York District, made a few interesting discoveries while inspecting the island.  “I saw movement in the water as the tide was draining one of the creeks,” Alvarez said. “I looked closer and saw something I’ve never seen — there were dozens of juvenile horseshoe crabs swimming within the tidal creek. They were the size of a quarter, but this meant so much more. It means that the restored island is now providing successful breeding for horseshoe crabs.”  download the pdf.

Counting Crabs

Listen to the audio clip

Until recently, the horseshoe crab was considered to be little more than a pest. When they come ashore to spawn, many die, rot and ruin beaches. The Bay of the Delaware River has the greatest concentration of horseshoes in the world. Five years ago, the spawning dropped suddenly. States all along the Atlantic coast moved swiftly to protect the horseshoe, including limiting its catch. But scientists cannot say if enough has been done to help it recover because there is so little information about the horseshoe crab. Bruce Schimmel joined one team getting ready to track and count horseshoes as they are about to come ashore and spawn at Prime Hook Beach in Delaware.

4th International Workshop on the Science and Conservation of Horseshoe Crabs

China: On June 15th-20th in Guangxi and Beihai, China, more than 140 scientists, conservationist, corporate representatives and governmental officials from 18 countries, attended the 4th International Workshop on the Science and Conservation of Horseshoe Crabs, to elevate our collective understanding of the world’s four extant horseshoe crab species, the conservation challenges they face, and how together we can overcome the ignorance and indifference that has for so long hampered efforts to protect these remarkable mariners.

In addition the presentation of papers and posters on the science and conservation of these species, ample time was set aside for working groups to address a host of conservation challenges from collecting data to complete the IUCN RED list assessment on Tachypleus gigas and Carcinoscorpius rotundicauda, to reducing the loss of critical spawning and nursery habitat, eliminating the unsustainable harvest for human consumption and bacterial endotoxin test production in Asia, and to develop an effective conservation message that transcends geographic boundaries, governmental malaise, linguistics, social and cultural indifference.

An important accomplishments to come out of this workshop was The Beibu Gulf Declaration on Global Horseshoe Crab Conservation, which represents our collected resolve towards the conservation of the world’s four extant horseshoe crab species by all those in attendance, and includes the establishment of the International Day of the Horseshoe Crab to be celebrated every year on June 20th.

Horseshoe Crabs Are at Risk—So Endotoxin Tests Are, Too

With a growing focus on the development of innovative biotherapeutics that have a higher risk of endotoxin contamination and the advent of personalized medicine requiring individual drug testing, endotoxin testing workflows are becoming more important than ever. However, relying purely on the horseshoe crab to provide this crucial safety test simply isn’t sustainable. In this article, we consider why protection of the horseshoe crab is so important for our own health, and how the validation of alternative endotoxin testing approaches offers a more sustainable solution. download the pdf.

Proposed Listing of the Red Knot as a Threatened Species Under the Endangered Species Act

Delaware Bay: Many of you – particularly those from North America – are aware of the importance of horseshoe crab eggs as food for migratory shorebirds, especially in Delaware Bay.  The US Fish and Wildlife Service has recently proposed that one of these shorebirds, the Red Knot, be listed as a Threatened Species under the Endangered Species Act.  Such action could have important implications for the future conservation of American horseshoe crabs.

We attach a copy of our letter to the USFWS, expressing our support for the proposed listing of the Red Knot.  While we support the measure, we do raise several concerns that should be addressed if and when the listing is approved.   download the pdf.

Stranded Horseshoe Crabs Helped by a Norwegian Youth

Norway: A few weeks ago, Kristian Fjeld and his grandmother Gry Handberg, traveled from Elverum, Norway, for the sole purpose of seeing horseshoe crabs spawn on Pickering Beach, Delaware. However, the journey started two years ago, when Kristian became interested in living fossils and discovered the horseshoe crab. Working with the Ecological Research & Development Group (ERDG) an international nonprofit organization headquartered in Delaware, with a mission to protect and conserve the world’s four horseshoe crab species, Kristian deepened his interest and desire to see this remarkable mariner. This interest, nurtured by his grandmother Gry, ultimately lead to the decision to visit the shores where this creature spawns in numbers not seen anywhere else in the world, the Delaware Bay. During Kristian’s visit he helped hundreds of stranded horseshoe crabs as part of ERDG’s Just flip ’em!™ program, and as a result, may hold Norway’s record for having rescued the most stranded horseshoe crabs. This fall, Kristian will start junior high school in Elverum.  He has already decided what he will study in the future, marine biology. The attached article from the local Elverum newspaper Ostlendingen, although in Norwegian, is in celebration of this remarkable young man, his loving grandmother, and a journey that took them halfway across the world.
