Norway leads the world aquaculture production of Atlantic salmon
Salmo salar and farmed Norwegian Atlantic
salmon is currently consumed around the globe. However, sea lice infestation is a
major problem faced by the salmon aquaculture industry in Norway and elsewhere. The
use of wild-caught cleaner fish, mainly wrasses, has been recommended over the other
available methods as the most economical and environmentally friendly option to
control sea lice infestation in salmon farming. Here, we review the development of
the Norwegian wrasse fishery and the use of wrasses as cleaner fish. In this
document, we address the sea lice problem and introduce the main wrasse species
employed as cleaner fish, document the cleaning behaviour of wrasses, present the
development of a new wrasse fishery associated with the salmon aquaculture industry,
and finally, we identify the main challenges associated with the intensive use of
wild-caught cleaner wrasses and provide some insight for future directions of the
wrasse fishery and further development of aquaculture techniques to supply salmon
facilities with domesticated cleaner fish.
