Categorization of artificial reefs
General categorization
- Material of the artificial reef: concrete, steal, ceramic, etc
- Types of general reefs: 65 types
| Concrete | cube type, cylinder type, half-sphere type, jumbo type, hexagon type, cone type, rugged type, improved rugged type, bridge type, bungalow type, half-cylindrical branching type, box type, reefs for shellfish and algae, square type built with electric poles, Large structure built with electric poles, arch type, triangular pyramid type, half-gearwheel type, small reef built with electric poles, recycled PC based block, cross type, tunnel type, cubic reef with fan-shaped platforms, tetrahedron type, improved square reef built with electric poles, multipurpose, double dome type, rib-enforced, hydrodynamically shaped large cubic structure, multipurpose triangular type, labyrinth type |
|---|---|
| Metallic | box type, double box type, reef for soft ground, large steel structure, mid-size reef for soft ground, octagonal hemisphere shaped large-size steel reef, octagonal hemisphere shaped mid-size steel reef, octagonal hemisphere shaped small-size steel reef, stacked cylinder type, octagon box type, dome type, jumbo type, combined trapezoid type, pyramid type, hexagram shaped steel reef, stereobate and tower type, octagram shaped type, triple-octagon compartments type, high and large steel structure |
| Composte material | ceramic for fish and shellfish, ceramic for shellfish and algae, steel type proliferation reef, polymer concrete, hybrid square, oyster shell, hybrid-type marine forest reef,pyramid structure, house-type marine forest reef, stone material combined type, train structure, steel-combined hybrid artificial reef, hexagon panel and H-beam, cross shaped ceramic |
| Others | wrecking, shipwreck reef |
Classified by water depth
- Artificial reefs are divided into nearshore reefs and coastal reefs
- Nearshore reefs: Reefs for fish such as 사각형 square type, hexagonal type, jumbo type, cylinder type, etc
- Coastal reefs: Reefs for shellfish, algae, and marine forest plants such as half-sphere type, bridge type, trapezoid type, etc
Classified by function
- Reefs for fish: Developed for spawning, growing, and feeding fish
- Reefs for shellfish and algae: Developed to breed, grow, and collect shellfish, and to inhabit and artificially transplant algae seeds
- Reefs for fish and shellfish: Developed as a multifunctional reef for fish and shellfish
- Reefs for marine forest plants: Developed to inhabit and grow algae, and to transplant artificial seedlings, enabling the spreading of algae
Classified by form and structure
- Surface structure type: Large effective areas [Mainly built with concrete for shellfish and algae along the coast line and marine forest reef]
- Frame structure type: Frame construction [Large steel structure based reefs serving as fish habitats in nearshore areas]
