The use of copper-containing impregnation has been one normal control strategy, but for both environmental and market reasons it is appropriate to try to reduce use of copper-containing impregnation. At the same time, it is important that the industry has effective methods to prevent vegetation that ensures optimal environmental conditions for fish and mussels. FHL aquaculture therefore took the initiative in 2004 to a project that would contribute to the Norwegian aquaculture industry benefiting as much as possible from the activities that took place in the development of various strategies to prevent overgrowth of nets - both nationally and internationally. The results show that in recent years there has been a constant development in which strategies used to keep the nets clean. The use of unimpregnated nets is developed and well tested on steel plants, but not for plastering plants. The strategy is cost-competitive with other strategies (including use of copper-containing impregnation). An adequate alternative remedy / substance has not been developed copper-containing impregnation that is commercially available for the Norwegian aquaculture industry. Increased use of large cages mean that fish farming companies are calling for solutions that require the least possible handling of the nets. Efforts are therefore being made to further develop washing solutions so that the nets can be washed at sea. In several of
the projects that take place nationally and internationally, one sees contours of interesting, future-oriented ones
solutions. Particularly interesting results are linked to the color of notlin, the use of coating that makes growth easy to
remove, frequent net changes (double nets) and washing. The solutions of the future may lie in combining several
of these “methods / results” and thus develop tailor-made solutions for the individual locality.
