Any surface submerged in the sea will be subjected to biofouling. Within minutes macromolecules like carbohydrates and proteins will have adhered to the surface forming a basis for the following succession of settling microalgae and bacteria that will be present at the surface within hours. Within days, larvae of macroscopic invertebrates like barnacles, ascidians, tunicates and blue mussels will have colonized the surface. Within one-two weeks a full biofouling community will be present at the surface. The generalized process here described of the development of a fouling community is of course depending on the availability of larvae in the water column, temperature and sea area, but these are the steps that essentially are involved in forming biofouling.
