Background Information
Horseshoe
crab populations are declining at a steady rate, the crabs are not currently
endangered but if their decline continues at the current rate there will be
problems in the near future. Horseshoe
crabs are a vital link in the food chain; specifically the crabs are prey for
other animals, as their population dwindles other species populations will
decrease as well. Migratory shoe birds
rely on Horseshoe crabs as food while migrating.

Fishery. 2005, July 16)

The problem of declining Horseshoe crab populations is a major issue that needs to be addressed immediately. Many people are involved in the decline of the crab’s populations and would be affected if their populations increased. Examples of people involved with the problem are researchers who use Horseshoe crabs, researchers who study horseshoe crabs themselves, fishermen who use Horseshoe crabs as bait, Horseshoe crab harvesters who collect the crabs then sell them and medical companies who use the crabs’ blood in their products.

The problem of
declining Horseshoe crab populations must be addressed because the crabs are a
vital link in the food chain, one of the oldest living species on the planet
and are widely used in the fields of fishing and biomedical engineering. A successfully built habitat for horseshoe
crab research and breeding would help to increase crab populations and provide
a way to obtain horseshoe crabs without taking them from the wild.
(Goehring, D. 2006, July 19)
(Burgeson, J. 2013, May 7)
The stakeholders
involved in the success of a Horseshoe crab rearing habitat are Horseshoe
Crabs, migratory birds that eat Horseshoe crabs specifically Red Knots,
scientists or students that will study Horseshoe crabs raised in the habitat,
future MAST oceanography students that will use the rearing habitat and
fishermen that could utilize crabs raised in a habitat as bait.
(Park, H. 2012, March 28)
The indented mood of the final
habitat is scientific. The habitat should fit in a laboratory habitat effortlessly.
(Kukla, M. 2008, September 17)
(McGrath, K. 2011, May 18)
(Bell, M. 2007, October 15)
There are currently products on the
market that are designed for raising different types of fish but there are none
for raising horseshoe crabs specifically.
On the market are also regular fish tanks found in a person’s home. Oceanography students are currently raising
horseshoe crabs in compartmentalized tanks.
(van Doorn, A. 2013, September 13)
Horseshoe
crab populations are declining at a considerable rate, the lack of crabs puts a
strain on migratory bird populations because the birds eat Horseshoe
crabs. As well Horseshoe crabs are
harvested to use as bait while fishing and used by medical companies. Increasing the abundance of Horseshoe crabs
will help increase shore bird populations, and harvesters can continue to
harvest the crabs. The primary objective
of creating a rearing habitat for Horseshoe crabs is to design a habitat that
can successfully function to research, test and breed horseshoe crabs.
