Using Flexi-Panel for Size-Grading and Harvesting
Flexi-Panel is most commonly used for passive grading, splitting the population in a cage to allow for selection and harvesting of the larger, faster-growing fish.
Once the grading operation is complete (when all the smaller fish have swum through the openings in the Flexi-Panel), you can either harvest the remaining larger fish directly from the sweep net or transfer them to another cage for harvesting at a later date.
With the appropriate size of aperture you can, of course, use the Flexi-Panel to size grade your fish at any stage of their growth. The clear benefit of this is that removal of the larger and more dominant fish allows the smaller fish to grow more quickly.
Popular sizes of Flexi-Panels for grading farmed salmon are 10m x 6m, 15m x 6m, and 20m x 10m, but there are no limitations to size. The individual apertures within the panel can also be made to any dimension, with increments of 1mm, the width determining the size of fish that can swim through.
Any size and any aperture can be made as each Flexi-Panel is constructed to the individual customer specifications.
