A handle for an aquatic aggregation apparatus that upon placement by measured passage with a line connected thereto provides for shelteringly attracting and accumulating aquatic organisms, the handle defined by an elongated member configured with a medial arcuate portion and a pair of distal arcuate seating portions for passage through and engagement with respective longitudinal opposing slots of a supporting member that further receives elongated slats through spaced-apart slots therein to define arms for the attracting and accumulating of aquatic organisms to and about the aggregation apparatus for facilitating fishing habitats, allowing the habitat apparatus to be hung from a dock or retrieved with a boat hook for ease in removal and relocation.

A structure for attracting fish in lakes and ponds is presented that includes a central mast with one or more angled shafts for the fish to rest upon and congregate near.

A modular ecological system is disclosed, comprising an ecological structure with a base section featuring a body with a first end region, a second end region, and upper and lower curved surfaces extending between the ends. Side walls converge at an apex region, creating a defined thickness and supporting lateral rods extending outwardly. The system includes a wheel and axle assembly attachable to the rods and a truss assembly with elements extending from the wheel and axle assembly to the apex, providing structural reinforcement. Flotation devices are attachable through openings in the curved surfaces to facilitate buoyancy. The system may include symmetrically arranged flotation devices, connection points, looped cables, and a load distribution nub on the upper curved surface. A method for assembling the system involves positioning and securing the wheel and axle assembly, engaging axle receiving sections, and attaching flotation devices through defined openings for stability in various environments.

An improved marine life sanctuary assembly that is completely underwater and is designed to duplicate a natural mangrove that provides protection and promotes an underwater ecosystem, which can help reverse the decline in the fish population, aviary habitats, erosion, and the like and help to promote land and marine colonization.

An artificial reef structure including thin tensile members as part of the structure. These tensile members readily accumulate marine life to create a more organic structure. The reef structure can accommodate a wide variety of ocean sensing and communication systems. Embedded lighting and electronic elements can be used to attract and monitor marine life.

An algal reef includes ash powder obtained by burning coal or biomass and a hardening agent that has hardened through a chemical reaction in a state of being mixed with the ash powder. The hardening agent may contain at least one of slaked lime or gypsum hemihydrate. The algal reef may include at least one of granules containing calcium carbonate or gravel as an aggregate. The granules containing calcium carbonate may be produced by the reaction of calcium hydroxide with carbon dioxide in a carbon dioxide absorption facility. In the algal reef, pellets containing the ash powder and the hardening agent may be put into a liquid-permeable bag.
