Reefs form from man-made substrates relatively easily, and they are certainly preferable to a lack of reefs altogether – but can artificial reefs really ever match their natural cousins? They offer shelter to fish during strong currents. The disappearance of coral reefs would lead to a catastrophic loss of biodiversity – coral reefs are thought to be the most biodiverse ecosystems on the planet, displaying a greater variety of life than even rainforests, and it is clear that we need to act now if these environments are to be saved – for many reefs it is already too late. These structures take a plethora of forms, from sunken ships to cinder block stacks, but as long as they are made of a hard substrate and are able to offer protection and a place for sheltering organisms to spawn there is potential for a reef to develop in as little as two-three years.

With artificial reefs there are new places where fisherman can fish and therefor can relieve pressure from natural reefs. There are some definite advantages to the creation of artificial reefs and many of the disadvantages can be controlled through the creation of corrosion free materials that are designed to work with the current environment. It is also possible, however, that the number of tourists in total might increase in response to the increased number of dive-sites, having the opposite effect and causing dive sites in the region to become more popular. This lesson, from Xpeditions, asks students to consider whether artificial reefs are good for marine ecosystems. The region is encountering problems, however, one of which is local people choosing to develop their own personal reefs using suboptimal materials. This suggests that that artificial reefs may be encouraging fish to reproduce more than the naturally occurring reefs scattered throughout the oceans. It may promote irresponsible refuse management.

Also, some substrate promote growth of certain organisms over others. However, many of the marine animals attracted to feed and shelter around artificial reefs do not breed there, and simply visit from other regions of the ocean. An artificial reef can also lead to a high concentration of fish in one small area, creating heightened competition between species, and also, ironically, worsening overfishing in one specific area. The degree of attenuation of incident wave energy depends on the shape, size and material of the artificial reefs. some artificial reefs are merely clusters OF modules arranged on the seabed in regular or irregular configurations. In areas such as the Florida Keys, reefs are closely connected to the economy, attracting tourists that use local businesses and supporting fisheries. An place where we can see the alarming effects of rising temperatures and increasingly acidic waters is coral reefs, which experienced the longest, most widespread, and possibly the most damaging coral bleaching event on record between 2014 and 2017.

ARTIFICIAL REEFS - Some look at the placement of man-made objects in the ocean (on the seafloor, in the water column, or floating on the sea surface) as hard-surface opportunities for establishment of habitat for all sorts of plant and animal marine life to form highly complex community food chains. Reefs around the world are dying – approximately half of the world’s coral reefs have disappeared over the past 30 years, and many are showing signs of following in their stead – be it due to increased water temperature, sea level change or an influx of sediment in previously nutrient-poor conditions. They conclude by writing paragraphs explaining whether they think a new artificial reef should be created in Florida waters. In many ways, this is an elegant solution. Those with no experience may want to consult with local officials and conservation groups to see what kind of action is possible, and environmentally advisable.
