ABSTRACT:
An artificial ocean reef module includes a dome having a hollow interior region, an apex and a lower edge, a ventilation port in the apex leading to the hollow interior region, covered by a hollow guide member having two opposing openings to create a venturi effect to enhance circulation through the dome, and an access port adjacent to the lower edge, leading to the hollow interior region. A base member is preferably secured to the lower edge of the dome. A method of constructing the module, using a hemispherical form having an apex, includes the steps of spreading cement on the outer surface of the form, and creating an opening in the cement at the apex to serve as a module ventilation port. A second embodiment includes a module body formed of concrete and stones and having an outer surface, and a passageway through the module body, the passageway having interior walls, wherein some of the stones protrude from the interior walls for increasing the wall surface area and the module complexity and for limiting predator access to passageway inhabitants. A method of constructing the second embodiment includes the steps of pouring sand into a first form, pressing stones into the sand so that a portion of the stones protrudes above the sand, pouring cement into the first form, permitting the cement to solidify into concrete, removing the form from the concrete, and dislodging the sand from the stones, so that the stones protrude and produce an irregular surface to enhance module complexity.
