A-BIOMASS Stereo AI Fish Biomass Camera

Ace Aquatec is a UK aquaculture technology company based in Dundee, Scotland, with offices in Norway, Canada and Chile. It grew from a two-person family business into a supplier with a team of about 40, developing welfare-first technologies for fish farming across growing, predator protection and humane harvest.

A-BIOMASS uses two calibrated stereoscopic cameras that capture images simultaneously. Machine learning identifies each fish and key points such as tail and fins to estimate height, length and weight, tracking multiple fish at once by day or night. A surface box sends data over Wi-Fi or mobile networks to an online portal that shows total biomass and weight distribution across pens and sites, with automatic reports. The company also sells the A-HSU humane stunner for salmon and tilapia and the A-HARVESTCAM for harvest intelligence.

• Stereoscopic imaging: two calibrated cameras capture synchronised images of passing fish.
• Machine learning keypoints: detects tail, fins and body to estimate length, height and weight.
• Day and night operation: adapts to underwater lighting with high resolution and frame rate.
• Wi-Fi or mobile connectivity: surface box streams data to the online portal.
• Multi-site portal: total biomass and distribution across pens and sites with automatic reports.
• Health signals: early signs of disease or lice from imaging.

• Marine cage farms tracking fish weight to plan grading and harvest without netting.
• Tilapia and pangasius exporters adopting camera biomass and humane stunning to meet welfare standards.
• Land-based tank farms using biomass data to optimise feed rations.

• Gives on-demand average weights and size distribution for grading and harvest timing without manual sampling.
• Reduces handling and anaesthetic exposure, which supports fish welfare.
• Supports more precise feed allocation that can reduce waste.
• Proven accuracy above 97% for Arctic charr at Matorka after joint algorithm tuning.

Fish farmers are moving from feed-based growth estimates to direct camera measurement, and welfare standards such as BAP increasingly shape buyer requirements. In Vietnam and Southeast Asia, growth in marine cage culture and land-based tanks for tilapia and other species creates demand for non-invasive biomass monitoring and humane harvest equipment.
