Quorum disruption on industrial scale - an end to natural biofouling?

A critically important event in the life of nearly all marine invertebrates is successfully "settling".

Settling means transitioning from being a floating zooplankton larvae to living in or on the seafloor and other solid marine surfaces. like rocky ledge outcrops seagrasses and seaweeds

It was only relatively recently discovered that  the  larvae of each species  will only succeed in settling, if there is a biofilm of specific bacteria species covering that surface. Mussels, seaworms, barnacles: each requires  a specific microbial welcome mat to land upon
