Abstract
An artificial underwater habitat for crustacea comprising a plurality of tubular elements for a thermoplastic material having a density of 1.2 to 2, with the tubular elements having a flattened portion while allowing free flow of water therethrough.
[US3929100A]
Claims (11)
1. An artificial underwater habitat for Crustacea comprising a plurality of structures of thermoplastics material having a density of from 1.2 to 2, the structures comprising tubular elements, which are partially flattened at a point along their length while allowing substantially free circulation of water inside the tubular elements.
2. A habitat according to Claim 1, in which the internal diameter of the tubular elements is from 20 to 150 mm, the thickness of the wall of the elements is from 1.5 to 10 mm, the length of the elements is from 100 to 50 mm and the elements are partially flattened at one end.
3. A habitat according to Claim 1, in which the internal diameter of the tubular elements is from 20 to 150 mm, the thickness of the wall of the elements is from 1.5 t 10 mm, the length of the elements is from 200 to 1500 Him and the elements are partially flattened at a point half-way along their length.
4. A habitat according to Claim 1, in which the structures are randomly distributed underwater.
5. * A habitat according to Claim 1, in which the tubular elements are prepared by extruding, through a die, a molten composition comprising at least one thermoplastics material.
6. A habitat according to Claim 5 » in which said composition contains a filler.
7. A habitat according to Claim 6, in which the filler is ash such as that produced in municipal incinerators and thermal power stations.
8. A habitat according to Claim 5 » 6 or 7 in. which the thermoplastics material comprises a polymeric or copolymeric composition based upon vinyl chloride »
9. A habitat according to any one of Claims 5 to 8 , in which the thermoplastics i-oaterial comprises waste material.
10. A habitat according to Claim 1 , substantially as hereinbefore described with reference to Example 1 or 2.
11. A method of making an artificial habitat for Crustacea, which comprises depositing on the seabed a plurality of structures of thermoplastics material having a density from 1.2 to 2 , the structures comprising tubular elements which are partially flattened at a point along their length while allowing free circulation of water inside the tubular elements.
