Embodiment Construction

[0019] figure 1 The illustrated cage 10 is shown here placed in water 16 and is particularly suitable for fish farming. The cage 10 consists of a net 11 and is preferably fixed to the seabed 15 by means of attachments 12, 13, and said cage extends upwards to the water surface. Depending on water depth, currents, tidal range and soil properties, floating cages connected to the ground or land with different types of attachments and corresponding combinations of such cages are also available.

[0020] The cage 10 here has a rectangular shape, although of course different shapes are also possible. The cages herein may have different shapes, for example, may be circular or square or polygonal. For some applications it is also advantageous that the cage can also be closed at the bottom and / or top of the cage. Depending on the hatching period, it is also possible to place smaller cages inside larger cages so that different mesh sizes can be obtained.

Abstract

A net (11) is particularly suitable for a basket for pisiculture, which may be placed in sea or fresh water (16). The net (11) is made of a wire material (1), producible from individual spiral or similarly bent longitudinal elements, wherein adjacent threads (2, 3, 4, 5) are woven together. Said net is simple and economical to produce.

Description

technical field [0001] The invention relates to a net which is especially used for fish cages and can be placed in sea water or fresh water, and its manufacturing method and device. Background technique [0002] It is known to raise fish using cages made of netting (see eg JP 2002 045084 or WO 96 13973). Nets made of plastic are usually knotted at intersections, typically have a rope diameter of about 2-8 mm and must have smaller mesh openings of about 10-30 mm. Due to the large "material surface" of the nets, there is a risk that animals and plants (e.g. algae, seagrass, moss, mussels, etc.) Nutrients are not conducive to oxygen supply, which adversely affects the penetration of the net, which in turn affects fish farming. [0003] EP-B-0 979 329 discloses a high-strength metal mesh for preventing falling rocks or for fixing ground layers, the metal mesh being woven from high-strength steel wires bent into helical coils and having a three-dimensional structure. The steel...
