Twice a year, fish make a significant journey. The fish lift allows these fish to manoeuvre in a safe way without wasting any water. Via a self-cleansing fish passage, the fish are counted and the water quality is measured. Alarm signals are sent online to the administrator without any cables. This way the fish lift works on automatic fish migration optimisation and the progress of knowledge on the behaviour of fish. The fish passage can be controlled and read from anywhere in the world and is made from light weight recycled plastics.
