Offshore marine cages face punishing waves, dynamic currents, and rapid hypoxia events that can devastate an entire season within hours. Manual diver inspections and surface feeding inspections cannot scale.
Adira's sub-sea telemetry arrays combine high-frequency acoustic hydrophones with stereoscopic AI vision to continuously assess fish biomass, swimming velocity, and feeding satiety, eliminating wasted pelleted feed.
Turnkey sub-surface hardware and software designed to withstand saltwater corrosion, fouling, and offshore storm conditions.
Submersible stereoscopic computer vision nodes tracking fish behavior, schooling density, biomass growth curves, and feeding appetite in open-ocean cages.
Continuous optical and electrochemical sensing nodes monitoring Dissolved Oxygen (DO), pH, Salinity, Ammonia (NH3), Turbidity, and Microalgae blooms.
Autonomous marine telemetry buoys equipped with wave-kinetic and solar PV generation, lithium iron phosphate battery banks, and dual satellite/cellular transceivers.
Observed performance data across commercial salmon, sea bass, and shrimp farming installations.
