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 …

Bayesian optimization and Cartesian-grid simulations for artificial reef design
… methods to prevent these effects, natural coral reefs have demonstrated comparable wave energy dissipation to artificial defenses while also providing a positive influence on the ocean ecosystem. Therefore, this thesis presents an artificial reef structure with a drag coefficient that is an order …

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 …

Effects of Artificial Reef Implementation on Fish Populations in a Marine Protected Area: Bluefields Bay, Jamaica
… order to allow fish populations to rebound. An artificial reef was created within Bluefields Bay Marine Sanctuary, a newly created no-take preserve. The goal of the artificial reef is to provide protection and habitat for various fish populations. Once the population reaches carrying capacity, …

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 …

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 …

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 …

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
… role that habitat plays in the life history of reef-associated fishes is particularly significant 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 …

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 …

Can Waters Around Durney Key, Pasco County, Florida, Support Coral Recruitment to Artificial Substrates?
To determine whether an artificial reef installation is feasible, there must be a thorough characterization of the habitat. An understanding of both small-scale and large-scale environmental processes is needed to determine factors that potentially will influence the reef. Large-scale processes …

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 …

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 …

Epifaunal assemblage of a newly established oyster reef with two substrates
An artificial oyster reef constructed in Boca Ciega Bay, off of the War Veteran's Memorial Park, St. Petersburg, Florida, in 2005, was used to compare a mined shell material to the typical oyster shell substrate used in artificial reef projects as an alternative substrate and cultch material. Half …
