The biological effects of artificial reefs in Smith Mountain Lake, Virginia
Artificial reefs were installed in Smith Mountain Lake, Virginia, during the summer and fall of 1973 to evaluate the biological effects on the aquatic ecosystem. Virtually all sport fishes were attracted to the reef areas. The frequency of sport fish on the reefs generally coincided with their …

Net Productivity On Artificial Reefs In the Mississippi Sound Estimated From Settlement Plate Measurements
<p>The use of artificial reefs as a coastal management tool has become increasingly popular worldwide. The Mississippi Sound has 67 inshore artificial reefs sites, the main goal of which is to increase the production of economically and recreationally important fish, such as speckled trout, white …

An Economic Analysis of Using Retired Vessels to Create Artificial Reefs in Costa Rica
… for the country, but the degradation of coastal reefs has resulted in a significant loss of financial income for developing areas. As a result, many of these areas are searching for methods to revert the degradation of coral reefs.</p> <p>Artificial reefs play an important ecological role in …

Fungal Biofilm Colonization and Succession on Artificial Reefs in the North-Central Gulf of Mexico
… mixed-species fungal biofilm communities on artificial reefs in the marine environment. Previous fungal biofilm studies have failed to observe the naturally-occurring biodiversity in coastal areas, which comprise the most utilized zone of the marine environment. Artificial reefs can increase …

Identification and Genetic Diversity of Lake Sturgeon Larvae on Artificial Reefs in the Huron-Erie Corridor
… and habitat reconstruction. The creation of artificial reefs may be a sustainable management option by allowing the fish to increase their population sizes naturally. Three artificial reefs were built in the HEC in hopes of replacing spawning habitat. To verify the success and efficacy of the …

Resident Benthic Fishes of Artificial Reefs in the Mississippi Sound: Effects of Habitat Relief and Subregion
<p>One of the fundamental questions of artificial reef research concerns the capability of these manmade structures to promote secondary production. Many researchers have questioned whether artificial reefs increase the production of fish biomass, or simply aggregate existing fish biomass. Most …

Reef fish demographics on Louisiana artificial reefs : the effects of reef size on biomass distribution and foraging dynamics
… given the dramatic increase in the number of artificial reefs deployed in coastal ecosystems over the past 50 years. In the Gulf of Mexico, the oil and gas industry has added a significant amount of structure to the Louisiana continental shelf, creating the largest de facto artificial reef …

Evaluation of two reef materials and point or cove locations for construction of artificial reefs in Smith Mountain Lake, Virginia
… initiated in April, 1973, to evaluate the use of artificial reefs in Smith Mountain Lake, Virginia. Twelve areas of the reservoir were selected for study. The sites were chosen from SCUBA and fathometer survey data on the basis of uniformity of water depth, substrate type, amount of submerged …

Community Structure and Production of the Macrobenthos on Four Artificial Reefs in the Mississippi Sound in Relation to Substrate and Profile Type
… its coastal fishery resources by creating artificial reefs. Through this effort, 73 nearshore reefs have been created across the MS coast. Different substrate types used to construct MS artificial reefs include oyster shell and cement rubble. Two types of reef architecture used include high …

Artificial Reef Performance in Lake Pontchartrain, Louisiana
Artificial reef development is a common fishery enhancement tool used in aquatic systems worldwide. In 2003 and 2004, a series of artificial reefs were constructed in a large oligohaline estuary, Lake Pontchartrain, Louisiana to improve recreational fisheries. The reefs are the first in Louisiana …

Assessing Respiration Rates and Nutrient Dynamics of Aritifical Reef Biofilms and Bacterioplankton in the Mississippi Sound
<p>Artificial reefs are primarily used to provide a suitable habitat for target fish populations, but the structures can also improve water quality and benefit non-target organisms. Laboratory incubation experiments were conducted in the presence of biofilm on rubble and in its absence to examine …

Quantifying biotic interactions with inshore subtidal structures: comparisons between artificial and natural reefs
Artificial reefs have been deployed purposely worldwide to influence physical and biological processes around coastlines and in inshore waters; often to augment recreational diving and fishing, support environmental mitigation and habitat restoration and, more recently, for scientific research. The …

Sinking Poor Decision-Making with Best Practices: A Case Study of Artificial Reef Decision-Making in the Florida Keys
The natural reefs of the world are experiencing higher use and pressures, resulting in anthropogenic impacts that are deteriorating many coral stands and creating poor water quality. The Florida Keys rely primarily on the reef system that surrounds the archipelago for their socioeconomic health and …

The Effect of Spill Contaminants on Marine Biofilms and Microbially-Induced Corrosion of Carbon Steel
… of life found in the deep-sea when they become artificial reefs. Spilled crude oil and chemical dispersant from the Deepwater Horizon (DWH) spill may have impacted the preservation of deep-sea historic shipwrecks and their microbiomes if they are located in areas where oil and dispersant were …

Coral conservation programmes in Bali, Indonesia: restoration of degraded reefs and localised socioeconomic benefits
Coral reefs, the “ocean’s rainforests”, are valued at over US $1 Trillion globally through the provision of ecosystem services such as including food production, biogeochemical cycling and tourism. Over the past several decades, these ecosystem services have been threatened by anthropogenic …

Artificial reef creation using decommissioned pipeline protection structures - environmental performance in the North Sea.
… the reuse of mattresses, for example as artificial reefs (ARs), has not been investigated. This thesis provides novel evidence regarding the potential environmental performance of these structures as ARs. Ecological assessments of O&G infrastructure are increasingly being conducted using …

Marine Communities of North Sea Offshore Platforms, and the Use of Stable Isotopes to Explore Artificial Reef Food Webs
… methods were used to compare the food web of an artificial reef located<br/>off the south coast of England with that of a nearby natural reef system, revealing a<br/>similarly complex food web, with similar trophic structure, and similar inputs from<br/>the available food sources. Isotope methods …

Spatial ecology of adult spotted seatrout, Cynoscion nebulosus, in Louisiana coastal waters
… showed clear habitat preferences, whereby oyster reefs and mud-bottom habitats of the estuary proper were used to a greater extent than channel and marsh regions. Seasonal and size trends in habitat use were also evident, as larger fish (> 400 mm TL) showed a high affinity for structured (reef) …
