Disclosed is settlement substrate for oyster technology, and, in particular, the present disclosure relates to a concrete settlement substrate for oyster and a preparation method thereof, and a construction method. The concrete settlement substrate for oyster has the characteristics of induction of rapid settlement and metamorphosis of sessile organisms thereto, promotion of long-term growth and good durability, and the oysters are settled on a surface of concrete. A reasonable spatial layout is utilized, such that each concrete pile (block) can effectively break waves and ensure smooth exchange between water bodies on two sides. After oysters settled to each concrete pile (block) breed a large amount, the water bodies can be purified, and the ecological environment in the surrounding sea area can be improved.

A coral holder which either resides in an aquarium or in a transport container. The coral holder may be either a fixed object or an insert. The coral holder has one or more coral channels, preferably elongated channels, which accept corals or coral plug(s) held securely in place anywhere along the channel(s) until the user desires to adjust or remove the coral plug.

A reef replacement system including: a front vertical open side having a horizontal lower edge and a parabolic upper edge, an upper layer extending from said parabolic upper edge to a height approximately equivalent to the height of said lower edge, wherein said system also includes at least two super-imposed cavities underneath said upper layer.
