The document discusses several areas of concern regarding oyster shell replenishment including consistent funding needs, increasing shell prices due to competition, and a limited 10-25 year supply of fossil shell. It also notes the unique machinery originally built in 1964 used in shelling operations.

3. Areas of Concern
• Consistent funding-Shells must be replenished
regularly to maintain productivity-currently $7
return for $1 spent
• Increasing shell prices-competition among
restoration partners and private industry
• 10-25 year supply of fossil shell
left(dependent on rate of removal)
• A unique set of machinery originally built in
1964

GearTypes Versus Harvest
Patent Tong Dredge Hand Scrape Harvest

11. Alternative Substrate
• Stone
– Needs to be appropriate size
– 4 to 5 times amount deployed compared to shell
– Suitable bottom
• Crushed Concrete
– Free of any foreign objects(plastic, rebar, other
construction materials)
• Deployable 3-D structures(castles, reef balls,…)
– Harvest resistant
– Can create user conflicts
– Good for shallow water/fringe
