A device comprising a corkscrew; a substantially flexible shaft operably attached to the corkscrew at a first end of the shaft; and one or more protrusions extending from the shaft between the first end of the shaft and a second end of the shaft. Methods of using the device are also disclosed.

Systems and methods for creating habitats for benthic macro-invertebrate organisms and fish are provided. The system contains a platform and woody material attached thereto. The platform also contains openings for trapping useful organic materials, such as leaf pack and wood, and tassels that provide additional habitats or attached the woody material. The system may be installed in a river, stream, creek, or other fresh water source. The platform may be substantially flat, or may be bent to form a hollow-tube-shaped structure, with openings at both ends of the structure. The systems provide habitat, places to hold on during high flows, places to trap useable organics such as leaf pack and wood and nesting areas to support macrobenthic organisms. The system can be placed into a stream channel to restore the stream or maintain healthy conditions in a stream.

A shark barrier includes a plurality of resiliently flexible, elongate members that extend in a generally upright condition between a sea floor and a sea surface. The elongate members are arranged so as to have the appearance of a thicket, preferably a kelp forest, when viewed from within the water and include magnets to assist in deterring certain shark species. The elongate members may be secured to the sea floor by an anchoring base and are held in the generally upright condition by a buoy or buoyant material held within the elongate members.

The present invention pertains to optical wave guides (ie structures that guide waves by restricting the transmission of energy to one direction) buoys, anchors, and climate change. The Algal Wave Guide directs energy to Algae in maritime and lake environments in order to expand the viable range of highly productive carbon sequestering environments such as the Brown Algae among others. Sequestering carbon at sea has several advantages over terrestrial methods such as lower cost, surface availability compared to land based real estate, reduced infrastructure, increased fishery quotas, commercial chemical and lubricant production, tourism, fertilizer inputs, etc.
