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.
