weather conditions – at very exposed locations – the interaction between fish net, sinker tube and cage flotation collar functions optimally, which is why several fish farmers along the harsh Norwegian coastline have now invested in a significant number of these nets Midgard for their farms.


THE AQUALINE MIDGARD SYSTEM® CONSISTS OF A NUMBER OF KEY ATTRIBUTES:


1. Newly designed fi sh net in which the sinker tube is connected directly to the net’s baseline rope, with the total weight of the sinker tube coming onto the net. Additionally the sinker tube lifting and lowering ropes when not in use are completely loose and independent of the net tensioning sys- tem. This totally eliminates the risk of these ropes coming in contact with the net and potentially causing net wear or damage. 2. A system where power winches are built into the cage for lifting and lowering the sinker tube with fi sh net connected. This can be done at a fully

ears of painstaking research and rigorous testing have culminated in the Aqualine Midgard System®, designed to prevent escapes and keep fish, and fish farm workers, safe. In addition to the work Aqualine have initiated themselves, they


synchronised gradual and constant lifting speed for the full circumference of the cage, all done in a totally controllable operation. This operation can easily be performed in a fast and effi cient manner, without endangering the fi sh stocks contained within the net or most importantly not putting the farm workers operating the system at a safety risk. To power this winching system only requires one portable electric generator (mounted on a boat) to power all the winches involved, with no requirement for numerous service boats with hydraulic cranes fi tted.
