A method of assembling a cage according to claim 8, characterised in that, The method comprises the following steps: S1, when the net cage needs to be assembled, four vertical columns (1) are vertically placed, the vertical columns (1) are fixed by external fixing mechanisms, and then the lower connecting frames (2) are fixed with the vertical columns (1); S2, then the truss (3) is hoisted by hoisting equipment, so that the truss (3) moves horizontally between adjacent connecting frames (2), workers pull the slide rods (5) on both sides to make the slide rods (5) move along the slide cavities, thereby moving the connecting plates (6), the positions of the insertion holes (20) on the connecting plates (6) are adjusted, and the insertion holes (20) on the connecting plates (6) are accurately aligned with the insertion holes (20) on the connecting frames (2); S3, if the insertion holes (20) on the connecting plates (6) cannot be aligned with the insertion holes (20) on the connecting frames (2) by the movement of the slide rods (5) alone, the position of the connecting plates (6) is adjusted by the adjusting assembly, so that the slide rods (5) can assist in aligning the insertion holes (20) on the connecting plates (6) with the insertion holes (20) on the connecting frames (2), after the alignment of the insertion holes (20) is completed, the bolts are inserted into the insertion holes (20), so that the connecting plates (6) are fixed with the connecting frames (2), and then the joint between the slide rods (5) and the truss (3) is welded and fixed. S4, through the above operation first to the lower truss (3) is installed in turn, then in the upper truss (3) is installed in turn, when the truss (3) is installed, the breeding net (4) is fixedly installed between the plurality of trusses (3), complete the assembly of the net cage.
