Horseshoe Crab Spawning Activity After Beach Nourishment

New York: Beach nourishment is a common shoreline protection method where sediment that has been eroded is replaced, typically using sediment dredged from offshore. To test its efficacy, a team of researchers led by Dr. Mark Botton from Fordham University investigated how beach nourishment projects affect horseshoe crab spawning. The study was conducted at Plumb Beach near the mouth of Jamaica Bay in Brooklyn, New York. This site provided a good study location because it has a history of beach nourishment projects. download the pdf.

The Fourth International Workshop on the Science and Conservation of Horseshoe Crabs

China: In early 2005, ERDG and a number of horseshoe crab biologists and conservationists from around the world began discussions about the need to have a forum in which we could meet, exchange ideas, and plan future research and conservation strategies. This effort culminated in the 1st International Workshop on the Science and Conservation of Horseshoe Crabs, held in the fall of 2007, in New York, USA. After which, it was decided to hold these workshops every four years at locations throughout the four horseshoe crab species spawning range. The 2nd workshop was held in Hong Kong, June 13 -16, 2011. The 3rd workshop was held in Sasebo City, Japan, June 15 -19, 2015. The 4th workshop will be held in Qinzhou City, Guangxi Zhuang, ARC on June 15 -20, 2019. learn more

Horseshoe Crabs, the Red Knot and a Broken Rung

Delaware: This is a story about horseshoe crabs, but we’re going to start by talking about a bird, the red knot, because that’s what people noticed first. We’ll get to the crabs (they aren’t really crabs) and how they save lives (so many lives!) and what’s happening in Asia (it’s even worse than what’s happening here) and climate change (of course). But first, the bird. download the pdf.

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.
