How Optilice 4 works

Optilice works
The fish is pumped from the cage for the Optilice 4-treatment, using the SQ 16 fish pumping system. The fish is counted, and then bathed in temperature-controlled water (-1C – 36 °C seawater or fresh water) in a controlled and time-adjustable time treatment. The underwater circulation of 1000 ltr/sec per line secures a continuous supply of fresh seawater (10 m3/hour per line). 

After the treatment, the fish flows back to the cage, and all sea lice are filtered out and destructed. The system comes with an open construction for easy access, control and cleaning, and a flow of fresh seawater in the outfeed-chute/pipe. Optilice 4 provides a reliable, robust and good monitoring of fish welfare. The system can be combined with grading-equipment and is Optimar Commander compatible.
