In a cooperation project with NORCE Research, we have delivered our two first pilot systems of the FRS cameras to BKK. BKK, who is interested in the local fish population and migration patterns, has installed the systems at two suitable fish ladders. We are looking forewards to working together with both BKK and NORCE to further develop the system and implement customer ideas and requirements.

Mohn Technology is continuously working on testing and improving our machine vision algorithms for our different camera systems. After we completed a prototype test of our FRS camera (Fish Research System) this winter with NORCE LFI at Byglandsfjord, we got new footage to test.
Machine vision is one of the most important aspects of the FRS camera, and high precision algorithms help us deliver the best possible results. The FRS allows the user to efficiently monitor underwater life with greatly reduced manual data processing efforts.
This version was trained on a small data set, but the results were pretty impressive. The machine vision algorithm detects fish that are hard to see manually (especially those inside the net).
The system provides both still images and video, which makes it easy to verify and classify the fish.
Theis particular setup, with a fishing net funneling fish past the FRS camera, is used by NORCE to research fish population in lakes and fjords. It is one of many ways to use the FRS camera to gather data about marine life.
Mohn Technology is currently testing an underwater stereo camera system with Institute of Marine Research. The accuracy testing performed this time was done by comparing the distance between the white dots on a calibration bar to the camera based measurements. The distance between the dots is 596,4 mm, and most measurements had a margin of error around 0,5%
These kinds of tests are important to verify the hardware accuracy under different conditions and improve software. Underwater machine vision measurements are more complex due to the poor light and contrast. The underwater stereo camera is a compact version of what is used in the autonomous Fish Research System (FRS)
Mohn Technolgy is working on an autonomous net cleaning system. Early pool testing and development is done on a simplified prototype that has an umbilical for live tracking of the process. The autonomous properties can be transferred to future prototype versions even though they will differ greatly from this early version. Both the prototype and future vessel is battery powered.
The automatic wall tracking is possible by the use of an accurate IMU (Inertial measurement unit), a stereo camera and some clever programming.
Cool way to end the YoungFish season, with an interesting lecture on reducing food waste with Jaja Bergen and Lerøy Seafood!
We got to taste, smell and feel different seafood in order to learn about quality and when it is really past due. Dont just look at the date, use your nose!
Test of a new biomass tool with IMR
A new and updated prototype of our autonomous Fish Research System camera was installed at a NORCE-facility in Byglandsfjorden. The object is to remotely register fish activity and test the system performance.
A short and successful test of a new and innovative tool for the fishing fleet! The trail main object was to test how easy launch and recovery of our tool from a fishing vessel in operation would be. Everything went as planned!
Thanks to all who visited us at the AqKva aquaculture conference 17. january.
A lot of nice people stopped by, who we really enjoyed talking to! There were also many very interesting exhibitors and presentations.
