BioSeaLice -- Effect of electric field as a barrier for spread of free-living and infective salmon lice larvae (Lepeophtheirus salmonis)

BioSeaLice -- Effect of electric field as a barrier for spread of free-living and infective salmon lice larvae (Lepeophtheirus salmonis)

Electric fences represent a non-invasive method to prevent sea lice infestation and rely on physical damage with limited resistance development potential.

Over the last decade, the development of pulsed electromagnetic (EM) fields around net pens has been shown to significantly reduce infestation rates of farmed salmon. Commercial systems are available and these can be deployed with a range of voltages (30-48V) covering the surface 10 m of farm pens.

However, important parameters such as lethal levels and how the pulses impact the salmon lice physiologically are still unclear; the currently used settings are derived from experience in large scale setups and are not systematically evaluated in terms of efficiency and cost effectiveness (power consumption).

BioSeaLice aims to determine the impact of electric fields on larval stages (nauplii and copepodids), lethal levels and potentially altered behaviour, physiological responses at the cellular level, recovery time and the ability of surviving larvae to infect and survive on the salmon hosts.
