Why Clean a Dock or Marina?

-       Reduce weight burden on floating structures
-       Reduce decay on organic structures
-       Reduce risk to patrons and vessels
-       Allow for structural inspection and maintenance
 
Rapid growth:
Oysters and barnacles can establish small colonies between 2-6 months and grow to 3-6” individually. New growth continues to layer on top of old growth over time.

Decay:
Hard fouling creates a small ecosystem that supports decay-associated microorganisms which migrate from the sea floor. Some organisms feed on organic materials. organism waste products can deteriorate organic materials.
 
Patron risk:
    Oysters and barnacles are filter feeders, accumulating toxic reservoirs of aquatic pollution introduced by urban activity. The calcium carbonate shells have sharp edges that can cause serious injury and infection.
