Artificial Breeding of Horseshoe Crabs 人工繁殖馬蹄蟹

Production: Paul Shin and S.G. Cheung, filmed by: Alice Chan, Department of Biology and Chemistry, City University of Hong Kong

Starting from 2006, Ocean Park Conservation Foundation Hong Kong (OPCFHK) has partnered with City University of Hong Kong (CityU) to work on improving artificial breeding and rearing practices, as well as life support system for horseshoe crabs.  Great footage set to soft pleasant music showing the spawning and embryonic development of fertilized eggs until hatching.  (3:30) 





The Count: Conserving Long Island’s Horseshoe Crabs

Leslie Von Pless, 2015.  http://wakemultimedia.com/2015/06/22/the-count-conserving-long-islands-horseshoe-crabs/   (11:25)

documentary on the process and significance of collecting data by surveying spawning horseshoe crabs on Long Island, including interviews with several researchers and citizen scientists;  emphasizes the critical connection of sustaining horseshoe crab populations to Red Knots, a shorebird species recently federally listed as “threatened” that depends on horseshoe crab eggs for food during its spring migration.

The Indian Horseshoe Crab

Pandey, Mike (producer). Riverbank Studios, New Delhi, India.

This video clip introduces the pioneering research of Dr. Anil Chatterji on potential new biomedical applications of materials extracted from the fluid inside horseshoe crab (HSC) eggs; includes great close-up photography of HSC embryos moving inside a transparent fluid-filled membrane, and views of scientific procedures used for extracting eggs and sperm from HSCs as part of the research. Concludes with a message promoting conservation of the species.

Nick Bakers “Weird Creatures” Series

Comprehensive, compelling and creatively-conceived look at horseshoe crabs from Nick Baker “Weird Creatures” series.  Using the unifying theme of its long evolutionary history of survival, the film brings in various HSC experts, along with extensive footage of spawning on Delaware Bay to explore interesting aspects of HSC anatomy, life cycle, ecology and importance to man.  Includes a nice piece about halfway through on the biomedical use of HSC blood, and another segment further along featuring HSC vision expert Dr. Bob Barlow describing the eyes.  The final third of the video documents the use of HSCs for bait and the key linkage HSC eggs provide to hemispheric shorebird migration. In closing, a strong case of concern is made for potential threats to that survival posed by human activities today.  (47:07)

Epic Wildlife

Quick & simple introduction to the anatomy, life cycle, ecology & values of the HSC from Epic Wildlife TV series.  Point of interest:  The opening shots of the strange wildlife form from Russia (that was used to justify the HSC for inclusion in the piece) is actually not an HSC at all (appears to be a Triops crustacean)!  (2:33)
