An artificial reef is a human-created underwater structure, typically built to promote marine life in areas with a generally featureless bottom, to control erosionblock ship passage, block the use of trawling nets, [2] or improve surfing. Many reefs are built using objects that were built for other purposes, for example by sinking oil rigs through the Rigs-to-Reefs programscuttling shipsor by Saaving rubble or construction debris.

Other artificial reefs are purpose built e. Shipwrecks may become Tje reefs when preserved on the seafloor. Regardless of construction method, artificial reefs generally provide hard surfaces where algae and invertebrates such as barnaclescoralsand oysters attach; the accumulation of attached marine life in turn provides intricate structure and food for assemblages of fish. The construction of artificial reefs began in ancient times. Persians blocked the mouth of the Tigris River to thwart Arabian pirates by building an artificial reef [3] and during the First Punic War the Romans built a reef across the mouth of the Carthaginian harbor in Sicily to trap enemy ships within [4] and assist in driving the Carthaginians from https://amazonia.fiocruz.br/scdp/essay/benedick-and-beatrice-argument-quotes/enzyme-catalysis-and-enzyme-inhibition.php island.

Artificial reefs to increase fish yields or for algaculture began no later than 17th-century Japan, when rubble and rocks were used to grow kelp. Beginning before the s, US fishermen used interlaced logs to build artificial reefs. More recently, refuse such as old refrigerators, shopping carts, ditched cars and out-of-service vending machines replaced the logs in ad hoc reefs.

Officially sanctioned projects have incorporated decommissioned shipssubway cars, battle tanks, armored personnel carriersoil drilling rigs and beehive-like reef balls. Artificial reefs tend to develop in more or less predictable stages. click

First, where an ocean current encounters a vertical structure, it can create a plankton -rich upwelling that provides a reliable feeding spot for small fish such as sardines and minnowswhich draw in pelagic predators such as tuna and sharks. Next come creatures seeking protection from the ocean's lethal openness—hole and crevice dwellers such as groupersnappersquirrelfisheels and triggerfish. Opportunistic predators such as jack and barracuda also appear. Over months and years the reef structure becomes encrusted with algaetunicateshard and soft corals and sponges.

An electric reef is an The Benefits Of Biorock Saving The Coral reef where an small low voltage electric charge is applied to a sub-sea metallic structures that causes limestone to precipitate onto a metal frame onto Coarl coral planulae can then attach and grow; the process also speeds up post-attachment growth. Artificial surfing reefs have been created in several locations.

Supporters cite benefits such as coastal protection, habitat enhancement and coastal research. This reef was constructed of large granite rocks placed in a pyramidal shape to form an appropriate breaking wave form that would suit surfers. An artificial reef constructed of over massive, geotextile bags each larger than a bus filled WITH sand was constructed in at Narrowneck on the Gold Coast of Queensland, Australia. This artificial link had two objectives: stabilizing beach nourishment and improving surfing conditions.

Artificial reefs can show quick increases in local fish population rehabilitation, coral reef and algae growth. However, far more than half the amount of biomass found on artificial reefs is attracted from other areas rather than developing there. Instead they operate as fish aggregating devices FADs bringing here fish from other reefs. Concentrating fish on a reef also makes for easier fishing. Benefiys continues. The fish attracted to artificial reef zones vary from reef to reef depending on its age, size and structure.]
