We design, build and supply
cabled underwater fish and wildlife monitoring systems
that are ideal for monitoring fishways (for example see
Node 10) and any other
artificial or natural underwater habitat. These
units are self-cleaning and designed for long-term, semi-permanent or
permanent
installation in freshwater and marine environments.
Typical hardware and software
configurations consist of 1- 4 live underwater
streaming video camera/sensor pack systems that
automatically filter, collect and transfer novel and
interesting fish activity for outreach, education and research. Our systems
have the following general features:
-
30+ metre (>100 feet) waterproof conduit and
connectors for shallow or deep installation
-
580 lines color high-resolution
video (1/3 SONY Super HAD CCD sensor)
with infrared illumination at night (48 infrared LEDs)
-
Biological data are
algorithmically filtered and analyzed
-
Video and all sensor data
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
-
System can detect
and log signals from
electronically-tagged fish (148 - 152 MHz) using an
external radio receiver and can receive and transmit
sound from each node
-
Water and air temperature stored every 30 seconds and
continuously uploaded
-
Low maintenance self cleaning
glass lens with variable
duty-cycles depending on water conditions and nutrient
levels

These fish monitoring systems use two
levels of post-processing to filter and analyze data.
Level one processing occurs on-site using proprietary fish detection
algorithms. Secondary processing is cloud-based
and takes place when the system automatically sends
pre-processed video data to our central computers.
These machines run sophisticated AI algorithms that
identify fish species, count and measure fish abundance
and return video highlights and data summaries to our
clients. Archival video is automatically posted to
the web and hosted by Biotactic.com (ARCHIVES
here).

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.
