  1. Transplant wild-grown coral onto artificial substrate

    A study in 2009–2011 on a coral reef in the Red Sea, Egypt (Herler & Dirnwober 2011) found that all wild-grown stony corals Acropora digitifera and Acropora selago transplanted onto an artificial substrate survived for at least nine to 15 months. Nine or 15 months after transplanting, all transplanted Acropora digitifera and Acropora selago colonies survived. Wild colonies of Acropora digitifera and Acropora selago (approximately 25 cm diameter) were cut from their natural 1–2 m depth reef with a saw, through the coral rock close to their base, rather than live tissue. Four colonies of each species were transplanted in October 2009 and 12 of each species in April 2010. Colonies were attached with epoxy resin to 10 cm2 or 12 cm2 PVC plates, each of which was attached to a 28 × 35 × 5 cm concrete block with two 1.5 × 5 × 0.1 cm steel plates fixed with steel screws and plastic dowels, which could be removed to allow the PVC plate and colony to be weighed. Colonies were orientated towards the same cardinal direction as in their original location. Both colonies were surveyed in January 2011.
