Sustainability
In order to be able to increase production with increased sustainability, the challenge is to solve the problem of lice without using polluting chemicals or methods that damage fish health or reduce the quality of the fish.
Salmon lice naturally amongst wild fish, and there are also species of fish that feed on lice. Wrasse and lumpfish are widespread along the coast and are well-suited to our climate. They have proven to be effective for cleaning up in fish farming facilities.
Utilising knowledge of offshore technology, many companies are planning large aquaculture cages that are moored well out to sea, and possibly lowered beneath the lice belt. The cages can be constructed up to eight times as large as today's standard size.
A closed tank or net provides full control over everything that enters and exits. This gives control over the environment and greater opportunities for the growth, health and wellbeing of the fish. Salmon lice, escapes and unwanted emissions can in principle be eliminated in a closed facility.
