Which organisms are of concern in biofouling?

Explanation:
Biofouling is the buildup of living organisms on submerged surfaces, starting with a microbial film and progressing to larger attached forms. The most troublesome fouling organisms are sessile mollusks such as clams, mussels, and oysters, because they attach firmly and form dense colonies that roughen surfaces, increase hydrodynamic drag, clog intakes, and raise maintenance issues. Algae and bacteria are part of the initial microfouling stages, but the question emphasizes organisms that persist as major surface foulers, which are the bivalves listed. Fish and insects don’t typically act as lasting fouling agents on submerged structures.
