Abstract
Artificial substrates for use in open sea enhancing biomass and/or absorbing wave energy, improved by means of particular dispositions and devices concerning their number, mooring, flotation, and using buried anchors and inertia weights. The artificial substrates are associated with affixed sessile organisms such as algae and shellfish and implanted securely even in very rough seas. The fulfill economical requirements for the development of aquacultural farms, aquacultural breakwaters, algae fields and shellfish reefs.
Claims9
An artificial substrate comprising:
- a first bouyant tube having a first end and a second end, the first end being connected by a flexible line to a bottom mooring, the first bouyant tube and the flexible line having lengths such that the first bouyant tube floats in a vertical orientation in a positioned permanently below lowest water level;
- a second bouyant tube having a first end and a second end, the first end being connected by a flexible connector to the second end of said first bouyant tube, the flexible connector and the second bouyant tube having lengths such that the second bouyant tube floats (a) in a substantially vertical orientation with its second end at or just below water surface at high water level and (b) in an inclined orientation at low water lever;
- and
- sessile organisms attached to the first and second bouyant tubes.
1 more element
An artificial substrate for growing sessile organisms thereon, comprising:
- a first bouyant tube connected at a first end by a flexible line to a bottom mooring, the first bouyant tube having an outer surface selected to facilitate attachment of sessile organisms;
- a second bouyant tube connected to a second end of the first bouyant tube;
- and
- means for flexibly connecting the first bouyant tube to the second bouyant tube,
- wherein the second bouyant tube is arranged and constructed such that it stands vertical at high water level and is inclined at low water level.
