BioMetrics AS proudly announces the Aquaculture Biomass Monitor the next generation in biomass measurement for net pen aquaculture.

Now, for the first time, there is an easy to use, buoy mounted system that operates continuously in the net pen, collecting data on thousands of fish per hour, from the entire water column, automatically calculating the size, depth and swim speed for each fish detected.

Advanced software has been developed to create fully customizable, easy to read reports, automatically transmitted via the Internet to feed barge operators and management.

Operators now have, in one package, a versatile and innovative new product to help increase feeding efficiency, monitor behavior and chart the daily growth of net pen populations.

  • Technology, testing and background

    BioMetrics AS of Kristiansund, Norway, has partnered with BioSonics Inc. of Seattle, USA, a world leader in scientific split beam sonar systems, to bring decades of accurate and defendable marine fisheries measurement expertise to net pen aquaculture.

    BioMetrics and BioSonics, collaborating with Norwegian salmon producers, have conducted extensive testing at operational salmon farming facilities.

    Over 5,000 hours of net pen data have been collected, analyzed and calibrated with slaughter reports to develop accurate fish size estimation software.
