Sea lice control in fish farms

LG Sonic advances in lab tests for sea lice control

The LiceSonic research project, started by a European Consortium coordinated by LG Sonic to develop an environmentally friendly solution to control sea lice in open finfish production, has advanced into lab testing. The first lab tests provided positive results for the further development of an ultrasound solution to control sea lice.

Problems caused by sea lice

The objective of the consortium is to develop a system that targets sea lice by combining ultrasound technology and water quality and fish monitoring. Yearly economic damages caused by sea lice exceeds € 1 billion in reduced production and pharmacological treatment costs. Innovations in sea lice control are needed as using bioactive substances is becoming less efficient. In addition, the process cannot be further increased as wild salmon populations and the ecosystem need protection.

Environmentally friendly sea lice control

Ultrasound technology is a proven technology to control algae and biofouling effectively without causing damages to the environment. The first feasibility study resulted in a reduction of 60% in attached sea lice to salmon by using ultrasound technology combined with fish and water quality monitoring. Different ultrasonic sound wave frequencies will ensure sea lice develop no resistance to the ultrasonic control method.


The consortium is formed by European companies LG Sonic, Control Data Systems (CDS) and Sonic Norway. CDS is a company highly experienced in offshore communication and data systems. Sonic Norway has extensive knowledge of the harsh marine environment in which finfish production facilities are located. Sonic Norway is well known in the aquaculture industry and has close relationships with end-users in the Norwegian market.
