Biofouling is one of the main problem of fish farming. It causes clogging of the net, thus reducing the amount of water entering the cage and lowering the oxygen level. A special non-toxic paint is applied to the nets to prevent biological pollution. This dye makes the surface of the mesh prickly and prevents organisms from settling.
It prevents the formation of single-celled creatures, mussels and larval organisms and algae formed by various living things.
