Some are old and retired freighters and ships that once plied the oceans of the world but now serve as habitats for marine life. Others are newer reefs that have been designed and built for specific applications. With the field of aquatic habitat technology continually growi

This book was released on 2009 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This project builds on a previous effort to characterize reef fishes and corals on low diversity, mid and outer shelf banks (Sonnier, McGrail) in the northwestern Gulf of Mexico (Gulf). Previously, we investigated recruitment patterns through fine-scale surveys of low diversity reefs and collected new recruits off experimental settlement structures. The aim of the current work was to expand the scope of our recruitment survey to include both low and high diversity coral reef habitats in the northwestern Gulf. Specifically, we quantified the density and diversity of juvenile reef fishes present on two low diversity (Sonnier, Stetson) and two high diversity (East and West Flower Garden) banks. This work was originally planned for the summer of 2008; however, our first two scheduled trips on the RV MANTA (new vessel of the NOAA Flower Garden Banks National Marine Sanctuary) were cancelled by NOAA due to mechanical problems. In response, our survey period was changed to September when another vessel (RV Fling) was available. Unfortunately, due to Hurricane Ike, which caused the Galveston Campus of TAMUG to close for the entire fall semester, this vessel was no longer available for research during the planned survey period. In response, all surveys were conducted in the summer of 2009 and the sampling effort (number of cruises) and temporal scope increased because we were able to combine vessel time from 2008 and 2009"--Project summary.

Available in PDF, EPUB and Kindle. Book excerpt: Artificial Reefs in European Seas focuses on artificial reef research in the Mediterranean and NE Atlantic. The book describes most of the long-term projects running in European seas, presents the legal and economic issues, and suggests future uses for artificial reefs in the European context. Readership: Professionals working on or interested in the uses of artificial reefs for fishery management, coastal zone management, aquaculture and nature conservation. The case studies of reef research programmes make the book ideal for degree students studying topics in ecology, and fisheries and coastal management.

Download or read book Estimating Reef Fish Reproductive Productivity on Artificial and Natural Reefs Off the Atlantic Coast of the Southeastern United States written by Bryan Lawrence Danson and published by . This book was released on 2009 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Artificial reefs (ARs) are generally designed to increase habitat for reef fishes, especially economically important species [e.g., black sea bass (BSB; Centropristis striata)]. The three principle goals of ARs are to create reef habitat to reduce fishing pressure on natural reefs, to enhance production of reef fish species, and to provide habitat in areas that increase the convenience or efficiency of harvesting reef-associated species. No known research has attempted to assess the enhancement of reproductive productivity of reef fishes on ARs off the southeastern Atlantic coast. The present study first attempted to document spawning on four South Carolina (SC) ARs from 2008-2009 via histology in four abundant reef fishes: BSB, gray triggerfish (Balistes capriscus), red porgy (RP; Pagrus pagrus), and vermilion snapper (Rhomboplites aurorubens). The present study then investigated the reproductive production of BSB on two ARs and one natural reef (NR) off Charleston, SC, by estimating potential annual fecundity (PAF) m−2 in the spring of 2009. An equation relating fecundity to standard length (SL) was applied to estimates of density and length to estimate PAF m−2. The BSB fecundity assessment was conducted on fish collected by the MARMAP program at SC-NR from 2000-2009. Density estimations were collected through underwater 360-degree point count videos. Length estimates were obtained from fish collected via hook-and-line sampling on the ARs to document spawning. Spawning was documented on the ARs in RP and BSB. Black sea bass was found to exhibit indeterminate fecundity, spawning frequency was re-calculated, and batch fecundity was significantly related to fish length and weight. Potential annual fecundity m−2 was 2.5-fold to four-fold greater on the ARs than on the NR, owing to the greater density and greater mean SL of BSB on the ARs compared to the NR. The methods provided here allow the comparison of reproductive productivity in fishes between ARs and NRs for the purpose of evaluating ARs as tools to enhance production.

This book was released on 1982 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using small artificial reefs made of cement blocks, a community of shallow water reef fishes was experimentally studied in Barkley Sound (British Columbia) to examine the structuring mechanisms in this assemblage The community under study inhabited a shallow reef made of rock boulders. The abundance of fish fluctuated with the seasons The species diversity of this fish community was low (H' = 0.3-10), one species (Coryphopterus nicho/si) comprising more than 80% of the individuals present Four species of rockfishes ( Sebastes caurinus, S. ma/iger, S. me/anops, and S. pinniger) and three species of benthic fishes (Hexagrammos decagrammus, Jordania zonope, and Artedius spp.) were also common. Experimental communities were established on ten identical artificial reefs made of cement blocks. Two series of reefs, built six months apart on sand 10 m away from the natural reef, tested the effects of seasons on community development. A third series, built in direct contact with the natural reef, examined the effects of distance and isolation on community development In each series a species equilibrium (approximately 6 species) was reached within six months The specific composition of the artificial reefs was similar to that of the natural reef, although species other than Coryphopterus nicho/si were more abundant Both juveniles and adults of all species were present, except for the rockfishes, which were represented only by young individuals. Tagging indicated that the benthic species remained permanently on the reefs, whereas a yearly turnover in rockfishes occurred The intensity of interactions between species was estimated by measuring shifts in habitat use on the artificial reefs. Only Sebastes me/anops showed consistent shifts in its space use in response to changes in the density of other species Only two of these shifts appeared to be the result of interspecific competition. Interactions between species, with the exception of S. me/anops had little effect on the spatial distribution of fish within the reefs. I examined the significance of the patterns of similarity between communities inhabiting identical habitats. High similarity values are usually interpreted as indicating the equilibrium status -- that is communities structured primarily by interspecific competition -- of a community, whereas low values are usually interpreted in the opposite direction -- i.e non-equilibrium communities structured by mechanisms other than interspecific competition (mostly stochastic events). This was tested using a randomization test. The null hypothesis of the test was that random colonization from the surrounding habitats was sufficient to explain the community structure on the artificial reefs. Six additional reefs (one third the original size) were built to test the effects of habitat size on community structure. The observed values on the reefs did not differ significantly from the null values, indicating that mechanisms, such as competition, were not required to explain the structure of the community. Habitat size had a strong effect, and the interpretations of previous studies were re-examined in light of this finding.
