The main chemical input from aquaculture is from medicines and the treatment of pen nets with antifoulants.
The use of medicines in Marrine Harvest is always in strict compliance with the relevant regulations prescribed by certified veterinarians.
Antifoulants are chemical compounds used to prevent fouling, that is the growth of algae (seaweed) on nets and cages. Algal growth can hinder water circulation through the cages and cause oxygen depletion.
We are interested in assessing new eco-friendly antifoulants and physical control methods, such as net cleaning systems or systems using alternating nets in the same pen (environmental nets). The products that we use on Marine Harvest farms are those that have been demonstrated to have minimal environmental impact.
