Marine Antifouling

The accumulation of microorganisms, plants, algae, slime, barnacles and other sea life (also called biofouling) significantly impacts the shipping industry.  Biofouling increases drag on the vessel which reduces the overall performance and increases fuel consumption and maintenance costs. 

LSI has led the way in developing antimicrobials for use in marine antifouling coatings to help prevent biofouling on ship’s bottoms.



Aquaculture has become necessary to meet the increasing seafood demands of a growing population.  The marine aquaculture industry raises fish using net-pens.  These net-pens are susceptible to accumulating unwanted marine plants and animals, algae and other sea life.  Also called biofouling, the increase of biomass accumulation can be very detrimental to the fish environment and costly.  Biofouling can significantly increase the weight and drag and this added weight and drag can compromise the integrity of the net-pen, resulting in breakage and the loss of fish.  Biofouling also reduces water flow which can decrease the oxygen and increase the concentration of fish waste leaving an undesirable environment for the fish.

LSI has developed products that offer lasting antifouling performance in aquaculture applications. Some of the benefits include:

  • More control over the system
  • Reduced damage to the net and the system
  • More efficient systems
  • Reduced underwater cleaning
  • Less disturbance to the fish environment
