Autonomous Fish Monitoring & Counting Systems

Biotactic offers a variety of autonomous fish monitoring and counting equipment for purchase. We also provide end-to-end data analysis services. Please contact us directly to discuss your specific project needs, configuration and cable lengths, as well as data analysis options and pricing.
Autonomous Underwater Fish Monitoring Systems
Our BRAVO fish monitoring systems have been meticulously designed to facilitate long-term underwater data collection in open habitats such as streams, lakes, rivers, and marine environments or closed channels such as fishways, bypass channels, aqueducts, culverts or other fish passage structures at dams and other facilities. These clever systems broadcast and collect video data that can be used to identify, measure and count fish for research, management, education and public outreach - and they can keep themselves clean automatically without any need for underwater maintenance. Both our permanent and mobile systems are being continuously refined and improved.

Permanent Fish Monitoring Systems- BRAVO G3

We began designing and testing permanent underwater fish monitoring systems in 2005. In 2009 we developed the first self-cleaning underwater camera systems that allow the G3 system to operate continuously without maintenance in both freshwater and marine environments. The system uses fish detection algorithms to record archival activity both day and night while streaming video and water temperature live anywhere around the world. Systems can be both hard-wired or powered by a solar array and connected through satellite communications in more remote locations.
Our network and monitoring equipment have the following general features:
  • 15+ metre (>50 feet) waterproof conduit and connectors for shallow or deep installation in fresh or saltwater
  • 1000+ lines color high-resolution video (1/3 SONY Super HAD CCD sensor) with infrared illumination at night (infrared LEDs)
  • Low maintenance self cleaning glass lens with variable duty-cycles depending on water conditions and nutrient levels
  • Biological data are algorithmically filtered, time and date stamped and recorded to 500GB solid state hard drive on a single board 1.8GHz computer with a dual core processor, no moving parts and 8GB of RAM
  • Water and air temperature measured and recorded every 30 seconds
  • If requested, all video and sensor data will be continuously uploaded live to the internet through our central BRAVO network
  • Our fish monitoring systems can easily be upgraded to fish counting systems whereby recorded biological data are analyzed in near-real time using AI to determine species identification, abundance, direction of passage and net daily passage, peak passage rates as well as fish length and condition

    Mobile Fish Monitoring Systems- BRAVO M2

    These solar-powered fish monitoring systems are designed for use in remote locations where internet access or power may not be available. Fish activity is detected both day and night and recorded on SD cards.
    Our mobile systems have the following general features:
  • Fully waterproof sealed enclosure and camera with 15+ metre (>50 feet) waterproof cable
  • Stand alone power with continuous maintenance-free operation with one 12V deep-cycle battery and solar panel
  • Time and date-stamped video recorded to SD card (up to 32GB)
  • Variable frame capture rates (1-30fps) and motion detection to remove periods of inactivity to reduce data processing time
  • BRAVO Mobile M2 Fish Counting System

    Fish Counters and Data Analysis

    We have developed and meticulously tested machine learning AI software called the BRAIN (Biotactic Research Artificial Intelligence Network). Biological data captured using our M2 and G3 systems can be processed through the BRAIN which will determine species identification, abundance, direction of passage, net daily passage, peak passage rates as well as fish length and condition. For G3 systems streaming online this data analysis is performed each day and data is made available online within 24 hours providing clients with a near-real time understanding of fish dynamics in their system.


    PIT Tracking Antennas
    Passive Integrated Transponders (PIT), when utilized in fisheries studies, can facilitate the identification and tracking of individual fish without impeding or obstructing the normal biological behaviour of the tagged animal for it's entire life. PIT tags are a reliable, efficient and effective means for monitoring fish movements and habitat utilization over long periods of time. We can design and build PIT tracking antennas to suit specific site or structure specifications for both full-duplex and half-duplex tag types. A single antenna can be utilized to record fish passage, or several antennas can be synchronized together to record fish attraction and passage efficiency, for example, in fishways at dams. Tracking data are logged on-site and transmitted to the internet and by ftp for subsequent analysis.

    All antenna systems are manufactured, tuned and tested according to site specifications and specific study details.
