Anti-sargassum and anti-jellyfish net barriers
The most durable and resistant anti-sargassum and anti-jellyfish solutions in the world.

Discover our indestructible system: Zeus
Are you looking for a solution to protect local and tourist populations from invasions of jellyfish and toxic algae (sargassum seaweed, green algae, etc.)?
The protection of maritime areas from invasions of sargassum seaweed or jellyfish requires the use of long-term storm-resistant barriers. Our Zeus retention nets resist extreme conditions: 200 km/h and 4-meter waves.



Our 5 basic principles for a strong barrier net, without the risk of breakage :
1. R & D studies on barrier sizing and positioning, taking into account dynamic constraints (swell, wind, currents, bathymetry) and anchoring conditions.
2. UV-resistant mesh with high mechanical strength and the right elasticity and mesh size.
3. Materials designed for long-term maritime use under high stress (for example, rigid floats that do not disintegrate over time).
4. Installation by professionals who adjust the entire system for optimum performance.
5. Regular net cleaning (frequency to be determined according to location).
Calypso: Portable anti-jellyfish net barrier
We have developed a reduced and transportable version of the Zeus net: the Calypso.
Installed in 20 minutes in the morning by hotel staff, the net covers an area of 100 m of length and ensures the protection of swimmers all day long. In the evening, the net is collected and at the same time allows the swimming area to be cleaned by collecting plastic cups and other trash in the water.
The Calypso is supplied with fixation elements to the ground: screw anchors or sandbags depending on needs.

High-performance net barriers to protect coastlines and ecosystems
V₂O Marine offers tailored solutions to combat the proliferation of sargassum and jellyfish, which threaten coastal areas and beaches. With its anti-sargassum and anti-jellyfish barrier nets, the company contributes to protecting marine ecosystems while preserving nautical and tourism activities.
Zeus: A robust and modular barrier
The Zeus barrier net is designed to efficiently contain sargassum, jellyfish, and other floating debris before they reach beaches. Made from reinforced polyamide, this net stands out for its exceptional resistance to cyclones and extreme weather conditions. Its ballast system ensures optimal stability, even during massive sargassum (brown algae) or green algae wash-ups. Thanks to its modular design, it can be tailored to specific sites, whether port areas, coastal waters, or sensitive aquatic environments.
In addition to preventing sargassum intrusions, Zeus acts as a true security barrier, stopping algae and jellyfish proliferation from disrupting swimming and boating activities. Its exceptional robustness and ability to withstand severe storms make it the ideal solution for regions exposed to harsh climatic conditions.
Calypso: A portable net for quick deployments
Specially designed for quick interventions, the portable Calypso barrier net is a practical solution for restricted access areas or emergency situations. Lightweight and easy to install, this net provides excellent protection against jellyfish invasions and algae proliferation, even in calm waters. Its polyurethane floats ensure perfect buoyancy, while its high-tenacity polyamide structure guarantees durability.
With its portability, the Calypso can be quickly deployed on beaches or in port areas affected by sudden species invasions or macro debris. This net also helps maintain water quality by limiting the photosynthesis of invasive algae.
Eco-Friendly solutions to preserve coastlines
By developing these nets, V₂O Marine adopts an environmentally responsible approach aimed at reducing the impact of marine pollutants and protecting aquatic environments. The Zeus and Calypso nets help maintain the quality of coastal waters while limiting the spread of invasive species and floating debris. These solutions actively combat marine pollution while preserving swimming areas and protecting residents.
Thanks to their weather-resistant design, these nets also meet the demands of maritime operations and challenging weather conditions. With V₂O Marine, choose high-performance, durable equipment that meets today’s environmental challenges.
