Artifish has since the beginning of 2018 worked with the innovation project EDDI, as part of the study program Biomarine Innovation at NTNU in Ålesund. The project was delivered as a bachelor thesis in May 2019.


(Further down comes a basic description of the project, as well as the reason why the company started the project)

Cleaner fish

According to Store Norske Leksikon cleaner fish are; fish used in fish farming to fight salmon lice. Fish species included in this category are lumpfish and wrasse.

Cleaner fish have been used as a preventative method against salmon lice, and is used by large parts of the aquaculture industry today. Artifish believes biological delicing with cleaner fish can also be the solution to the lice problem. The use of cleaner fish is a more natural solution than for example the use of chemicals, which is an often used method in the fight against salmon lice today. The cleaner fish eats lice directly from the salmon without creating any damages to the salmon.

Unfortunately, cleaner fish does not have any natural conditions to actually eating lice, and thus the method is also not optimal. In addition, there is a significant size difference between cleaner fish such as lumpfish and wrasse, and farmed salmon. The salmon therefore seems daunting to the cleaner fish, which increases the stress level, and leads to inefficiency of the lice eating.

Today, it is under 40 % of all cleaner fish that eat lice during their life cycle in the fish farms.

Educational Digital Intelligence (EDDI)

Artifish has developed a product and a training system that will make the cleaner fish safer around the farmed salmon, and teach them to seek and eat salmon lice. To be able to confirm the training ability of the cleaner fish, a pilot project was completed, in which the cleaner fish, lumpfish were used. This gave promising results. Artifish believes it is realistic to be able to increase the efficiency of the cleaner fish by 125%.

The result of a more efficient cleaner fish, will primarily result in an increase in animal welfare in the fish farming cages. In addition, the aquaculture industry will be able to reduce costs related to delicing, which today is aroun 1 billion euros. An efficient cleaner fish will also lead to a reduction of salmon lice, which in turn will lead to growth in the industry and open up new farming licenses. The Norwegian aquaculture industry needs this solution, in order to live up to becoming Norway's future largest industry.
