A floatable frame (11) for supporting the net of an offshore fish farming apparatus comprises pairs of hoses (12a, 12b) arranged with the hoses of each pair interconnected to one another whereby application of sideways force by tidal movement or a vessel results in longitudinal compression of one hose and tension of the other hose, the successive pairs of hoses being rigidly interconnected at their respective ends whereby forces tending to deflect one pair of hoses either vertically or horizontally are transmitted to a neighbouring pair of hoses. |
