Abstract

A package (100) of steel wire mesh comprises a steel wire mesh. The steel wire mesh has consecutively along its length direction a first section (102), a second section (104) and a third section (106). The first section is coiled thereby providing a first roll (108) of steel wire mesh. The third section is coiled separately from the first section thereby providing a second roll (110) of steel wire mesh. The second section provides the transition between the first roll of steel wire mesh and the second roll of steel wire mesh.

The legs (11, 12) lie in different planes so that said first hooks (14, 15) can move past each other for closing the clip(10, 20, 36, 42). The first hooks (14, 15) are oriented towards each other. Each of these first hooks (14, 15) ends in a second hook (16, 17) and a wire end(18, 19). The wire ends (18, 19) are oriented away from each other.

Abstract

An aquaculture net (20) has one or more side walls. These side walls comprise wires (12, 14) in a wavy form with maxima and minima, wherein the maxima of one wire (12) interlock with minima of a neighboring wire (14) to form patterns of a series of diamonds. The one or more of side walls have at least two parts (22, 24) wherein the wire direction in one (22) of said parts is different from the wire direction in another (24) of said parts. The aquaculture net (20) thus combines the advantages of a net with horizontal wires in the side walls with the advantages of a net with vertical wires in the side walls.
