The Project

Development and commercialisation of safe, effective and user-friendly photonics based sea lice removal system for salmon farms

Background to the project

Salmon farms across the world are suffering from infestations of sea lice. Where infected fish have a far lower selling price due to the lesions the parasites cause, sea lice can also kill salmon. Any more than 3 lice on an infant fish and 10 lice on a mature fish can be fatal. Once sea lice thresholds have been exceeded, regulation requires fish farmers to undertake some form of sea lice removal treatment. Estimates of yearly losses caused to global salmon farmers run as high as $1 billion (€880 million). State of the art solutions to remove sea lice from salmons include use of cleaner fish (ballan wrasse and lumpfish which eats the lice from the salmon) and a range of thermal, chemical, mechanical and laser treatments. Cleaner fish has proven to be an effective solution but there remain major concerns over cleaner fish welfare conditions and the increased pressure on wild stocks of cleaner fish, particularly ballan wrasse. Thermal, mechanical and chemical treatments have shown their efficacy in removing the sea lice from salmon, they also remove the mucus layer from the fish which puts them at a high risk of a secondary infection. Laser technology is effective at removing lice however it only removes one louse at a time and there can be up to 20 lice per fish in some farms.

The Consortium

APS is an innovative Irish SME making great strides in the biophotonic field. The PHOTOLICER project is focussed on the removal of sea lice from farmed salmon using photonics.

UWAVE is a French SME specialising in the design and build of lights for the UV market.
