This book was released on 2017 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Artificial reefs (ARs) have been used around the globe for a number of years with the goal of enhancing local fish populations, species diversity and fishing opportunities for commercial and recreational fishers. However, central to the problem of quantifying AR productivity for mobile species is knowing when and for how long they are resident to the AR, and connectivity with adjacent natural habitats. To address this, 45 Kelp Bass (KB), Barred Sand Bass (BSB) and California Sheephead (SH) were monitored using acoustic telemetry on Wheeler North Artificial Reef (WNAR), and an additional 20 individuals were tagged at three adjacent natural rocky reefs near San Clemente, California. SH exhibited significantly higher site fidelity (proportion of days detected; 74 ± 27%) than KB (45 ± 38%) and BSB (30 ± 26%) to WNAR, however, BSB exhibited seasonal residency patterns. Additionally, within WNAR, fish displayed seasonal movement patterns characteristic of spawning behavior. Finally, all fish displayed residency to the reef on which they were tagged, and only 13.3% of all tagged fish were detected on a reef other than the tagging reef. Taken together, the long-term residency and site attachment behavior displayed by the three species examined here suggest that WNAR is serving as satisfactory habitat for these species by providing sufficient prey resources, and that WNAR is providing suitable habitat that meets important life history needs, such as spawning, thereby producing additional fish biomass to the area that would not have been created otherwise.

Download or read book Islands in the Sand written by Daniel A. McCarthy and published by Springer Nature. This book was released on 2020-10-22 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearshore hardbottom reefs of Florida’s east coast are used by over 1100 species of fishes, invertebrates, algae, and sea turtles. These rocky reefs support reproduction, settlement, and habitat use, and are energy sources and sinks. They are also buried by beach renourishment projects in which artificial reefs are used for mitigation. This comprehensive book is for research scientists and agency personnel, yet accessible to interested laypersons including beachfront residents and water-users. An unprecedented collection of research information and often stunning color photographs are assembled including over 1250 technical citations and 127 figures. These shallow reefs are part of a mosaic of coastal shelf habitats including estuarine seagrasses and mangroves, and offshore coral reefs. These hardbottom habitats are federally designated as Essential Fish Habitats - Habitats of Particular Concern and are important feeding areas for federally-protected sea turtles. Organismal and assemblage responses to natural and man-made disturbances, including climate change, are examined in the context of new research and management opportunities for east Florida’s islands in the sand.

This book was released on 2019 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Artificial reefs have been deployed throughout the worlds oceans to act as habitat and fishing enhancement tools. To expand current research on the role of artificial reefs in the marine community, ordination and multivariate regression methods were used here to analyze survey data of natural and artificial reefs. The reefs, located in the Northern Gulf of Mexico (NGOM) and on the West Florida Shelf (WFS), had been previously surveyed from 2004 to 2015 using remote operated vehicle and stationary video techniques. This study tested the hypothesis that similar functional roles are accounted for at both natural and artificial reef sites even if species composition varies. Secondly, it examines the role of environment and fisheries in determining the assemblages. Artificial reefs tended to host communities that were as biodiverse as natural reefs, although not necessarily composed of the same species. Results of an ordination confirmed that as the classification was broadened from the level of species, to family, to functional group, the assemblages on each reef type (natural vs. artificial and NGOM vs WFS) appeared more similar. Dominant groups were present at all levels of classification and included the families Lutjanidae and Carangidae, as well as functional groups Red Snapper and Small Reef Fish. Both natural and artificial reefs tended to be dominated by one of the following: Lutjanidae, Carangidae, or Small Reef Fish, although a continuous gradient was found across the extremes of natural versus artificial reefs. Generalized Additive Models were developed to examine the influence of reef type, location, environment and fishing intensity covariates. Results indicated that for both natural and artificial reefs, the abundance of families and functional groups can be influenced by environmental factors. In both cases, there is strong spatial autocorrelation suggesting connectivity with neighboring reefs.

This book was released on 2011-11-06 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reef fish spawning aggregations, ranging from small groups to many tens of thousands of individuals, are spectacular but poorly known natural phenomena whereby fish assemble at specific times and locations to spawn. For some species these large groups may be the only form of reproduction, the high fish numbers briefly giving a false impression of stability and abundance—an ‘illusion of plenty’. They are often a focus for intensive seasonal fishing because of their predictability and because many important commercial fishes form them. Highly vulnerable to overexploitation, many aggregations and their associated fisheries, have disappeared or are in decline. Few are effectively managed or incorporated into protected areas. Aggregations are not well understood by fishery scientists, managers and conservationists and their significance little appreciated by fishers or the wider public. To ensure their persistence to replenish important fisheries in coral ecosystems, maintain their ecosystem function and continue to delight divers, a significant change in perspective is needed to foster protection and management. This book provides comprehensive and practical coverage of the biology, study and management of reef fish aggregations, exploring their how, when, where, and why. It explores ways to better protect, study, manage and conserve them, while identifying key data gaps and questions. The text is extensively illustrated with many unique, never before published, photographs and graphics. Case studies on over 20 interesting and important fishes are included, outlining their biology and fisheries and highlighting major concerns and challenges.

Available in PDF, EPUB and Kindle. Book excerpt: The proximity of the two Rigs to Reefs projects and an operating oil and gas platform to the natural coral formations of the Flower Gardens (WFGB) afforded us the opportunity to not only compare several platform configurations, but also to compare the fish communities at "artificial reefs" to that of a neighboring natural system. It was therefore the purpose of this study to compare the fish communities associated with an operating oil and gas platform, two artificial reef configurations, and the WFGB. Reef configurations included a production platform toppled in place as a deep water artificial reef (West Cameron 617A), a nearby partially removed platform (High Island A355), and an operating production platform (High Island A350). We sought to identify species composition at each site; to estimate the fish biomass/density associated with each site; to determine the effects of side, depth, and distance from each site on fish biomass. Comparisons were then made between these sites and to other sites that had been surveyed.

This book was released on 2016-03-24 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a start-to-finish overview of the whole Fish4Knowledge project, in 18 short chapters, each describing one aspect of the project. The Fish4Knowledge project explored the possibilities of big video data, in this case from undersea video. Recording and analyzing 90 thousand hours of video from ten camera locations, the project gives a 3 year view of fish abundance in several tropical coral reefs off the coast of Taiwan. The research system built a remote recording network, over 100 Tb of storage, supercomputer processing, video target detection and tracking, fish species recognition and analysis, a large SQL database to record the results and an efficient retrieval mechanism. Novel user interface mechanisms were developed to provide easy access for marine ecologists, who wanted to explore the dataset. The book is a useful resource for system builders, as it gives an overview of the many new methods that were created to build the Fish4Knowledge system in a manner that also allows readers to see how all the components fit together.
Download or read book Community Structure of Demersal Temperate Reef Fish at Artificial and Natural Reefs in South Carolina as a Function of Reef Age and Season written by Carly Altizer and published by . This book was released on 2013 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: Artificial reefs serve numerous important functions in the South Atlantic Bight by providing new recreational fishing and diving locations, contributing to state economies, and providing additional habitat for economically valuable reef fishes. However, little is known about how fish communities develop in temperate regions once a new reef is deployed, how they compare to adjacent natural reefs, and how these communities are influenced by season. Therefore, SCUBA video surveys were conducted over a 13-year period (1999-2012) at four unpublished artificial reef sites, three published artificial reef sites of varying ages, and two natural reef sites to assess the impacts of ecological succession and seasonality on species richness, diversity, evenness, fish density, and community structure. Season and reef age had significant effects on diversity and community structure at the unpublished sites, while season alone accounted for these trends at the published sites. Black seabass and tomtate dominated reef fish community structure at the published sites, while economically valuable species, such as groupers and snappers, were more abundant at the unpublished and natural reef sites. These results suggest that fish communities develop quickly at new artificial reefs (i.e., within the first year post-deployment) and that fishing pressure on publicly known reefs may obscure or even prevent community succession.
