This book was released on 2002-08-09 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear-specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long-lived species are more vulnerable to towed fishing gear than short-lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries-the first time that such data has been assembled and analyzed for the entire nation.

Download or read book Ecology of the Marine Fishes of Cuba written by Rodolfo Claro and published by Smithsonian Institution. This book was released on 2014-06-17 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: Situated at the convergence of the Atlantic Ocean, the Caribbean Sea, and the Gulf of Mexico, Cuba's coastal waters are home to one of the most diverse fish faunas in the Western Hemisphere. However, until now, information in English about Cuban marine fishes and their habitats has been limited. This comprehensive guide to the region's fishes fills that void. Originally published in Spanish in 1994, Ecology of the Marine Fishes of Cuba has been completely updated and revised for this English edition. The book collects and expands on the findings of more than 20 years of work by and international team of ichthyologists and marine biologists studying the coastal fishes and habitats of Cuba. In chapters arranged topically, the thirteen contributors detail the physical characteristics of the Cuban coast; document the physiology, behavior, reproduction, feeding patterns, and growth patterns of the region's fishes; and survey Cuba's fisheries management programs. The result is an unparalleled integration of English- and Spanish-language references on coastal fishes of the western Atlantic, complete with a comprehensive bibliography that constitutes a valuable reference in its own right. The extensive information presented here establishes an important foundation for comparisons of regional biological variations and demonstrates the need for proactive habitat and fishery management policies in the area.
Download or read book The Ecology of Marine Fishes written by Dr. Larry G. Allen and published by Univ of California Press. This book was released on 2006-02-15 with total page 1353 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine fishes have been intensively studied, and some of the fundamental ideas in the science of marine ecology have emerged from the body of knowledge derived from this diverse group of organisms. This unique, authoritative, and accessible reference, compiled by 35 luminary ecologists, evolutionary biologists, and ichthyologists, provides a synthesis and interpretation of the large, often daunting, body of information on the ecology of marine fishes. The focus is on the fauna of the eastern Pacific, especially the fishes of the California coast, a group among the most diverse and best studied of all marine ecosystems. A generously illustrated and comprehensive source of information, this volume will also be an important launching pad for future research and will shed new light on the study of marine fish ecology worldwide. The contributors touch on many fields in biology, including physiology, development, genetics, behavior, ecology, and evolution. The book includes sections on the history of research, both published and unpublished data, sections on collecting techniques, and references to important earlier studies.

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

Book excerpt: Until recently, studies of the marine environment have neglected the physical structure and complexity of fish habitat, underestimating the impact of its degradation and simplification for stock sizes. In this publication, the author maintains that when fishery resources are depleted, harvest controls alone are ineffective for their recovery and subsequent conservation. Integrating ecological and management notions into a common framework, he sets forth the importance of habitat quality in its relation to the life cycles of marine populations, as well as the impact of anthropogenic factors on the abundance or absence of cover.--Publisher's description.
Download or read book Essential Fish Habitat Mapping in the Mediterranean written by Vasilis D. Valavanis and published by Springer Science & Business Media. This book was released on 2009-03-27 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proper designation of Essential Fish Habitat (EFH) is a highly important spatial measure in any management of fishery resources. EFH is defined as those waters and substrates necessary to fish for spawning, breeding, feeding, or growth to maturity, a definition that includes the physical, chemical and biological properties of marine areas and the associated sediment and biological assemblages that sustain fish populations throughout their full life cycle. This book presents latest advances in EFH mapping and modelling and introduces the environmental approach to EFH identification through the combined use of latest technologies and advanced techniques, such as Remote Sensing, Geographic Information Systems and Spatial Statistics. The contents of this book include overviews and comparisons of different approaches on species habitat modelling, methods to identify teleconnection patterns between large-scale meteo-oceanic phenomena and local environmental variation, and EFH maps for cephalopod, shrimp, hake, anchovy, sardine, and swordfish resources in the Mediterranean. The aims of this book are to provide accumulated knowledge on marine species essential habitat mapping and to be a source for further developments in the important topic of marine resource management.
