The lumpfish

The lumpfish is easily recognizable by its short, round body, and short fins, which make it a rather weak swimmer. To make up for its lack of swimming ability, the lumpfish has a round sucker disk on the underside of the body, so can be sedentary and sit and rest on the substrate or under shelters.

With sea lice being one of the main problems limiting the growth of salmon farming in the sea, many alternative solutions to chemical and mechanical treatments to prevent or remove sea lice are being researched and developed. This is a result of the intensified focus on fish welfare. But there is no doubt that the best biological and financial results are also achieved when fish welfare is in focus. Lumpfish eating the lice off the salmon while swimming together inside the cages has proven to be a very gentle, environment-friendly, and effective method to remove the lice.
