    SealFence Seal and Sea Lion Deterrent

    Intelligent Acoustic Deterrent

    SealFence is an intelligent acoustic deterrent system designed to deter seals and sea lions from attacking your farm.

    • Using a unique ultrasonic transmission developed by OTAQ, SealFence creates an acoustic “fence” of protection around your cages.
    • Engineered to provide long term reliability on exposed marine aquaculture sites,  the modular design of SealFence means there are no cables to run between cages;  so both installation and fault finding are simple.
    • SealFence features an optional ACM (Active Condition Monitoring) system which checks and records that every module on site is working correctly 24 hours a day.
    • With 100s of units in use protecting farms around the world, SealFence is a proven long term method of deterring seals.
