Biotactic Research And Videography Observatories
Our network and monitoring equipment are being continuously refined and improved and have the following general features:
- Self-cleaning underwater camera systems (Patent Pending)
- 30+ metre (>100 feet) waterproof conduit and connectors for shallow or deep installation in fresh or saltwater.
- 800 lines color high-resolution video (1/3 SONY Super HAD CCD sensor) with infrared illumination at night (infrared LEDs)
- Biological data are algorithmically filtered and analyzed and streamed live
- If requested by our clients, all video and all sensor data will be continuously uploaded live to the internet and to our central BRAVO computers for secondary biological analysis including species identification, fish counts, abundance estimates, behavioral trend analysis, inter-annual ecological relationships, thermal shifts in activity, responses to effluent, phenological trends, spawning and other ecologically significant activities
- Water and air temperature stored every 30 seconds and continuously uploaded to dedicated websites
- Low maintenance self cleaning glass lens with variable duty-cycles depending on water conditions and nutrient levels
Fish monitoring systems operate automatically using a DSL internet connection, AC/DC power and secure ventilated compartments. Applications include scientific research, agency-based fish and wildlife monitoring, marine biological applications, aquaculture, underwater surveillance, education and basic fun. Since 2005 our underwater fish monitoring network has been used to achieve long-term research objectives related to inter-annual variation in fish migration patterns, migration timing and habitat utilization on a global scale.
The video collected automatically by the BRAVO system is particularly useful for long-term research objectives related to inter-annual variation in fishway counts, fish migration patterns, migration timing, habitat utilization and reproductive behavior. The system has also been proven to be useful for monitoring species at risk, invasive species and observing behavior of benthic organisms such as mussels, crayfish, diving ducks, turtles, various spawning behaviour and wide range of fish and aquatic mammals like otters.
