Sensors System

Full overview, underwater and above…

As aquaculture tanks and ponds have become increasingly bigger and spread over larger areas, the need for high quality real-time video and sensor data has become more important. This has made farming a much more predictable and profitable business. The advanced Akvasmart cameras and sensor systems monitor fish behavior and condition, as well as any surface activites around the farm. Oxygen and temperature sensors monitors environmental conditions for live readings, as well as provide logged data for later analysis. Flexible camera solutions in monochrome or full colour provide crystal clear video images. All surface- and underwater images, feeding and environmental data are transmitted to a control room via wireless or hardwired network systems. From there it is possible to send the signals worldwide and operate the entire system from any PC. The opportunities are virtually endless!

The Akvasmart line of sensors include a wide range of products suitable for commercial fish farming.

Pellet sensors include both Doppler and IR sensors that detects uneaten feed below the fish' eating area in the cages. The signals from the sensors are used to modulate and stop the feeding automatically when the fish are full. The Fishtalk - AkvaControl software allow for adaptive feeding regimes when pellet sensors are used (the fish decides when and how much to eat). In other words: We make your fish talk!

Camera systems include both monochrome and colour cameras. Both underwater and surface mounted cameras are used to monitor the fish. Monochrome cameras are mostly installed as fixed "look-up" cameras monitoring the feeding process. The colour cameras are are used as both feeding and inspection cameras and are mostly controlled by a dual winch that allow for horizontal and vertical camera positioning in the cages. These cameras also have pan and tilt functions.

Environmental sensors include water temperature sensors, tidal current sensors and oxygen sensors (both galvanic and optical).

All pellet sensors, camera systems and environmental sensors are connectec to the feed control base via wireless control systems (CVU or CSU). Some cameras can also be connected to portable monitors or hardwired camera network systems if practical.

Our Vicass Biomass Estimator systems use stereo video images taken of the live fish swimming in the water to detemine length and height of each fish. This data is then entered into an algorithm for the actual fish specie in order to estimate the fish weight.
