Give Salmon a Fighting Chance
Against Sea Lice


Give salmon a fighting chance against sea lice
with Sea Lice Defence Technology

Introducing Sea Lice Defence Technology (SLDT) from GenusWave, the first solution to mitigate sea lice outbreaks and maintain fish immune system health. Sea Lice Defence Technology uses disrupts the sea lice host identification and host attachment process, making it harder for sea lice to infect salmon and complete their growth life cycle.

With SLDT from GenusWave, fish farmers can finally put sea lice on the defensive and give salmon a fighting chance.

Predation stress leaves salmon susceptible to sea lice.
Here’s how it works:

Predation Stress

In intensive aquaculture, farmed fish are exposed to severe stress from ongoing seal predation (nets don’t stop predation stress). Salmon’s immune system can handle most challenges, but long-term predation stress taxes a salmon’s energy reserves and overwhelms its defences.

Weakened Immune System
& Low Mucus Production

The salmon’s first line of defence against sea lice is its skin and mucus production, which form a natural protective barrier. But high levels of stress cause fish to produce cortisol and adrenaline, not mucus. With decreased mucus production and lower antibody levels, fish immune systems become weak and severely compromised.

Sea Lice Infestation

Once compromised, the fish immune system can’t fight disease, bacteria, and pathogens. Left highly susceptible to sea lice infestations, sea lice actively identify stressed fish and attach to the fish with compromised immunity. Without proper mucus production to support immune system health, stressed fish in aquaculture environments can’t defend against sea lice.

Sea Lice Defence

We’re putting Sea Lice
on the defensive

Sea Lice Defence Technology (SLDT) uses breakthrough sound technology to disrupt the host identification and host attachment processes and mitigate sea lice infestations.

Disrupt Host Identification

Sea Lice Defence Technology (SLDT) utilizes unique sound frequencies that stimulate mucus production and interfere with the ability of sea lice to identify and target stressed salmon. SLDT counteracts sea lice’s innate attraction to stressed fish and stops sea lice from completing their life cycle.

Stop Host Attachment

By conditioning seals to stay away from salmon farms, GenusWave’s Targeted Acoustic Sound technology eliminates predation stress on fish. Without predation stress, salmon are able to increase mucus production and build stronger immune defences, enabling fish to effectively fight off sea lice attachment.

Ultrasound Solutions

GenusWave’s patented Ultrasound Sea Lice Solutions delivers high vibration to the sea lice membrane, causing it to rupture. The Ultrasound Sea Lice Solution offers fish farmers a last line of defence for severe sea lice infestations that can’t be mitigated through other approaches.

Stop Sea Lice Identification and Attachment

GenusWave offers fish farmers a better way to prevent sea lice infestations

The latest research demonstrates that Sea Lice are able to identify and attach to stressed fish with compromised immune systems. As stressed fish begin to produce cortisol and adrenaline (primary stress hormones) their immune system is compromised and they become targets for sea lice. GenusWave technology uses a multi-step approach to prevent sea lice infestation before they occur.


First, GenusWave acoustic startle technology conditions seals to avoid salmon farms, thereby reducing predation stress on the fish. This allows fish to reduce cortisol release, which in turn leads to strengthened immune system defences.


Next, Sea Lice Defence Technology utilizes specialized sound technology to stimulate mucus production and disrupt the host identification and attachment processes, which sea lice need to go through to complete their life cycle. Mucus production acts as the primary line of defence against sea lice, making it difficult for ectoparasites (sea lice) to attach to salmon. By maintaining fish health and stopping sea lice identification, GenusWave brings to market the first preventative solution to stop sea lice attachment and support fish health.


Unfortunately, current treatments for managing sea lice have a range of unintended consequences that may worsen salmon health. For example, the use of use peroxide treatments and thermolicers remove the salmon’s mucus, leaving salmon susceptible to infections and diseases – including recurring sea lice infestations. Antibiotics can be somewhat effective at lowering disease rates, but antibiotic use leads to a host of negative consequences to both fish and the environment.

Ultrasound Sea Lice Solutions

Patented ultrasound technology for severe Sea Lice infestations

Sea Lice attachment causes chemical changes in fish skin, resulting in skin damage and open wounds, secondary blood loss, electrolyte changes, and cortisol release. Subsequently, these infections decrease fish immune responses, making them susceptible to other diseases and reducing growth.


With over 20 years or research on ultrasound treatments on small pathogens, GenusWave’s Ultrasound Sea Lice Solution targets nauplius and copepodid stages of sea lice and utilizes vibration to kill zooplankton (like Lepeophteirus salmonis, Caligus rogercresseyi, and water fleas), E. coli bacteria, and Zebra Mussel veligers.


Unlike chemical treatments and well boats, GenusWave sends ultrasound wave throughout the surrounding sea water that are harmless to salmon but deadly to sea lice. The treatment includes acoustic cavitation – gas bubbles that violently collapse – which are highly effective on tiny aquatic organisms due to the presence of microscopic gas pockets, which absorb the ultrasound wave’s acoustic energy. When key structures and membranes in the sea lice absorb that that energy, they rupture, killing the sea lice.
