A process for forming an artificial reef includes forming a form having a geometric shape, applying at least one blockout onto a surface of the form such that the blockout extends outwardly of the surface of the form, applying a sprayable concrete over the form and over a portion of the blockout, curing the sprayable concrete on the form for a period of time such that the sprayable concrete adheres to the blockout, and removing the cured sprayable concrete and the blockout from the surface of the form. The blockout is of a cast concrete material such as a cinder block. The blockout has openings therein so as to open to an interior of the artificial reef.

A rapidly deployable underwater coral cultivation system comprising a tensioned propagule support line or rod, and a propagule-encircling loop for attachment thereto, wherein the propagules' tissues and skeleton overgrow the line/rod. Multiple propagules of a single genetic clone on a line/rod may fuse into a single linear coral colony, whereby the natural structural and anti-fouling attributes of the target organism provide structural rigidity to the system and high survivorship of the live material in nursery culture. A preferred embodiment may provide a low to no maintenance protocol soon after deployment thereby allowing for set and forget through self-planting endpoints. In some embodiments, a vertical arrangement provides full leverage advantage to the support buoy as growth increases (coral) weight. In some embodiments, the vertically-oriented single genetic clone facilitates gamete capture for facilitated spawning in coral (ecosystem) enhancement and restoration.

A structure for attracting and accumulating aquatic organisms that is a simple, inexpensive, non-degradable unit, easy to assemble and use, as well as easy to retrieve and move for use in a different location, formed of a central 4 PVC pipe having cut outs through which are inserted bar slats made of solid, generally rigid, 100% PVC material. The bar installation is a compressed fit into the cut-out sections of pipe, forming a compress fit, self-expanding, spring-lock design. Holes may be drilled in each end of the central pipe so that a hook may be inserted in one end, allowing the habitat structure to be hung from a dock or tethered to another stationary object, or retrieved with a boat hook for ease in removal and relocation. Alternatively, the use of coupling connections permits joining one habitat structure to another in order to form a larger habitat structure.

A shoreline restoration method utilizes a plurality of apparatuses facilitating the formation of a vertical oyster reef. Each apparatus includes a rod frame and a plurality of individual mesh bags are positioned between an inner and an outer frame. The inner and outer frames include top and bottom frame portions and a plurality of side support frame members extending there between. Each individual mesh bag is aligned with at least one outer side support frame member and at least one inner side support frame member and wherein each individual mesh bag is coupled to an adjacent mesh bag. A plurality of cross ties extends between the inner frame and the outer frame and cultch material fills each individual mesh. The shoreline restoration method promotes shell accumulation and expands the tidal zone.

A netting conduit. The conduit defines a continuous channel extending between a first open end and a second open end. The conduit is fabricated from netting having a mesh size sufficient to prevent most fish from traversing through the netting material. The conduit tapers from the first open end to a midsection and enlarges from the midsection to the second open end. The longitudinal edges of the conduit can define a parabolic shape. The conduit further includes stakes that are usable to anchor the conduit to the bed of the waterway in which the conduit is in use.

The present disclosure provides generally for a system and method for planting flora, fauna, and dispersing various organisms through drone delivery. The system may comprise of a drone with seedling box that may hold and drop the pods containing flora or fauna. The seedling box may hold the pods with the flora or fauna in them and at specific intervals drop the pod with the flora or fauna. The seedling box may also hold various organisms or other materials and drop these organisms or materials when directed. A seedling box may comprise loading mechanism and deploying mechanism to facilitate accurate, timely deployment of the pods containing the seedlings. A pod may comprise a weighted tip with hollow cavity for seedling placement and a vertical rod for securing seedling during deployment. Where the system comprises uneven number of seedlings, seedling box may include counterweights to provide stability in configured flight patterns for duration of seedling deployment.

The blockout is of a cast concrete material such as a cinder block. The blockout has openings therein so as to open to an interior of the artificial reef.

The invention provides a marine infrastructure comprising a concrete matrix having a pH of less than 12 for use in promoting the growth of fauna and flora in aquatic environment, and methods for promoting the growth of fauna and flora in aquatic environment, including endolitic and epilitic flora and endolitic and epilitic anaerobic and aerobic flora and fauna.

An artificial structure for promoting microalgae growth includes a 3D-printed structure formed by positioning a printing surface on a movable stage of a 3D bioprinter in contact with a bio-ink that includes a mixture of a pre-polymer material with one or more of cellulose-derived nanocrystals (CNC), and microalgae cells. By projecting modulated light onto the printing surface while moving the stage, the bio-ink is progressively polymerized to define layers of an artificial coral structure with microalgae cells disposed thereon, where the artificial coral structure is configured to scatter light within the structure.
