摘要： System for vertical adjustment of a fabric 3 delimiting an upper part of a net cage, wherein the fabric is arranged along the whole circumference of the net cage. The system comprises an upper 4 and a lower 5 frame ring which the fabric 3 is fastened to, and a number of stay lines 7 running vertically between the upper and lower ring, as the lower ring 5 may be lifted by pulling the stay lines 7. The invention also comprises an alternative system for vertical adjustment of a fabric 3 delimiting an upper part of a net cage, wherein the fabric 3 is arranged along the whole circumference of the net cage. The system comprises an upper 4 and a lower 5 frame ring, and at the least one lifting ring 6 between, as the fabric is fastened to a fastening ring and the lowermost lifting ring 6A. A fastening ring may either be the upper frame ring 4, or an upper lifting ring 6. The system further comprises a number of stay lines 7 running vertically between the upper and the lower frame ring, as the lower frame ring 5 is lifted by pulling the stay lines 7, and a number of lifting lines 8 running vertically upwards from the lifting rings 6, to lift the fabric 3 by pulling the lifting lines 8. The invention also relates to a net cage comprising an upper part being delimited by a vertical fabric 3 arranged along the whole circumference wherein the water in the part has reduced salinity. The fabric may be adjusted vertically by a system as described above.
