Bubble Curtains Validated Through Trials in Ireland

Marine aquaculture operations are facing increasingly frequent and complex environmental challenges. As our environment continues to change, harmful plankton blooms, sudden temperature spikes, and changing water currents can all negatively impact fish health, adding stress and even reducing survival rates. These conditions make it harder for farmers to maintain consistent production while keeping fish healthy.  

Traditional methods for managing these challenges include chemical treatment or mechanical barriers, which come with limitations, high costs, and environmental impacts. The future requires sustainable tools that work with natural water conditions. The growing demand for high-quality seafood makes effective management more important than ever.  

Bubble curtain systems are emerging as a practical and effective method to protect fish farms. During Ireland’s 2024 Marine Challenge Program, over 1.8 kilometers of Bubble Tubing® was deployed across two commercial salmon farms, making this the largest bubble curtain installation ever completed in the country. 

Despite challenging offshore conditions, the results were impressive: 

• Consistent and reliable airflow under challenging conditions 

• 60% reduction in harmful plankton within the protected zones 

• Creation of a dynamic water movement that limits problematic organisms 

For salmon farmers, these results proved how large-scale bubble curtains can operate efficiently in even the most demanding conditions. By providing a continuous protective barrier, farmers can better manage risks, support healthy fish, and maintain production. Ultimately, helping the aquaculture industry thrive sustainably.
