DESCRIPTION:Is it possible to sustainably harvest a biogenic habitat build
 ing species? Oysters build the very habitat they live in\, with oyster ree
 fs often being the result of hundreds if not thousands of generations of o
 ysters growing on the remains of their ancestors. In healthy reefs\, the p
 opulation amasses enough shell to achieve growth\; compensating for the sh
 ell lost through decomposition\, transport and sedimentation. Large scale 
 harvesting of oysters presents a problem for maintaining the reef. The end
  result can be an imbalance in the shell material left behind compared to 
 what is needed\, and ultimately to the loss of this habitat. \nHere I pres
 ent a model that may provide the solution to the problem. I will present a
  model in which we simulate the gains and losses of shell to determine whe
 re the sustainability criterion of “no net loss of shell” lies. With t
 he uptake and consideration of this model in stock assessments\, fisheries
  management plans can start to define a “sustainable yield” of this bi
 ogenic species.\n
