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.

Available in PDF, EPUB and Kindle. Book excerpt: While artificial reefs may have much to offer, they remain an anecdote in the greater scheme of fisheries management, primarily due to the lack of data specific to validating their use. Based on papers presented at the 9th Conference on Artificial Reefs and Artificial Habitats (CARAH) and also including original articles written for this reference,

This book was released on 2017-06-26 with total page 948 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY-NC 2.5 license. The Gulf of Mexico is an open and dynamic marine ecosystem rich in natural resources but heavily impacted by human activities, including agricultural, industrial, commercial and coastal development. The Gulf of Mexico has been continuously exposed to petroleum hydrocarbons for millions of years from natural oil and gas seeps on the sea floor, and more recently from oil drilling and production activities located in the water near and far from shore. Major accidental oil spills in the Gulf are infrequent; two of the most significant include the Ixtoc I blowout in the Bay of Campeche in 1979 and the Deepwater Horizon Oil Spill in 2010. Unfortunately, baseline assessments of the status of habitats and biota in the Gulf of Mexico before these spills either were not available, or the data had not been systematically compiled in a way that would help scientists assess the potential short-term and long-term effects of such events. This 2-volume series compiles and summarizes thousands of data sets showing the status of habitats and biota in the Gulf of Mexico before the Deepwater Horizon Oil Spill. Volume 2 covers historical data on commercial and recreational fisheries, with an analysis of marketing trends and drivers; ecology, populations and risks to birds, sea turtles and marine mammals in the Gulf; and diseases and mortalities of fish and other animals that inhabit the Gulf of Mexico.

This book was released on 2013-10-22 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Artificial habitats have been used for centuries to successfully modify environments for the benefit of Man. In the aquatic environment, the use of artificial habitat technologies is of growing interest worldwide. Opportunities exist in both developed and developing nations to apply these technologies in many areas, including classical scientific investigations of ecosystem structure and function, engineering advances in underwater technology, and fisheries and environmental management. The applications of artificial habitat technologies are taking on ever greater economic, social, and environmental importance globally, not only in developed countries such as Japan where highly sophisticated technologies are used, but also in developing nations, where lower cost practices are in use. There is growing pressure to increase production, while at the same time preserve or enhance the environments and ecosystems surrounding fisheries. This book provides a comprehensive review of the facts, issues, and global trends emerging regarding the use of artificial habitats in aquatic ecosystems. It presents the most recent scientific advances in ecology and engineering technologies related to the building of artificial habitats, and it also presents many of the fisheries management and socioeconomic and environmental issues. Artificial Habitats for Marine and Freshwater Fisheries will be of interest to a broad audience including natural resource scientists, planners, and managers, particularly those interested in aquatic and fisheries science and management; organizations and individuals interested in commercial and recreational fishing; ecologists; environmental economists, engineers, lawyers, and social scientists; and geographers. Presents a global scope Draws together, for the first time, disparate literature Contains contributions by authors in the United States and Japan Features engineering chapters that focus on Japanese advanced technology often not available to the English language audience
