2000mW
A new era in bird control
Around 50.000 seabirds are killed each year due to bycatch in trawl fisheries worldwide. Bycatch has the highest at-sea impact on seabirds, killing hundreds of thousands, potentially over 1 million, seabirds annually and affecting 30% of the world’s 359 recognised species. Seabirds are the most threatened bird group, with about half experiencing population declines and 31% globally threatened – making this a critical global conservation issue.
How does Birdlaser work?
Birdlaser AquaBeam is equipped with a 2000mW (NOHD 2 Meter) laser module with a constant green laser beam to project a bright green 520 nm moving laser point. The moving laser point is perceived by birds as a physical object. When the laser beam comes close to birds, they fly away as it is perceived as a bird of prey coming from above.
At sunset and sunrise, dust and fog particles in the air are illuminated by the laser beam, and the entire beam becomes visible. During these periods, the birds perceive the entire beam as a stick, and the entire length of the beam becomes effective.
Laser can rotate 360 degrees and cover all area around the boat.
Birdlaser AquaBeam is built in stainless steel and has a range of 2500 meter, the efficiency varies with light and atmospheric conditions.
Birdlaser AquaBeam is mounted on fishing boats aft area keeping the birds away from trawl area.

Reducing Seabird Bycatch in Fisheries Using Laser Based Deterrence Technology
Seabird bycatch remains a critical issue in global fisheries, with large numbers of birds unintentionally killed each year through interactions with fishing gear. Traditional mitigation methods — such as bird-scaring lines, weighted hooks, and night setting — have had some success, but challenges remain, especially under variable conditions and for certain vulnerable species.
To address this, we have developed an innovative laser deterrence systemdesigned to protect seabirds by actively keeping them away from high-risk zones around fishing operations. The system projects dynamic laser patterns across the surface of the water, which seabirds instinctively perceive as a threat, triggering a strong avoidance response without causing harm.
Key advantages of the laser deterrent include:
-
Non-lethal and non-invasive: No physical contact or injury risk to the birds.
-
Highly flexible: Can be adapted to different fishing vessel types and operational settings.
-
Continuous protection: Active both day and night under a range of weather conditions (with specific tuning to light levels and visibility).
-
Reduced operational disruption: Allows normal fishing activities to continue without complex additional gear or procedures.
By integrating this technology into fishing practices, we aim to significantly lower seabird mortality rates, contributing to healthier marine ecosystems and more sustainable fisheries.
