Most floating fish cages consist of a floating cage collar, mooring system, and net cage hanging freely down from the floater. Any current moving through the net will deform the net. This deformation depends on the current velocity, the nets ability to attract forces, and the gravity forces from weights at the lower end of the net. The forces on the net will vary with the deformation. This paper shows that for this kind of cage, a reduced velocity Vred = U·(ρ/2G)1/2 , where G is the equivalent weight per area of the net, will be sufficient to estimate the drag force and deformation of the net. The present work is analytical, combined with computer simulations. The reduced velocity parameter could be used to determine the needed bottom weights. The quick estimation of the drag force on the net could be used as an input to mooring design.
