Book Description
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.

Book Description
Inspired by the International White Shark Symposium in 2010, Global Perspectives on the Biology and Life History of the White Shark incorporates the most important contemporary research findings into a single peer-reviewed book. This beautifully illustrated reference represents a historic change in the context of White Shark (Carcharodon carcharias) research. Once considered one of the most poorly understood and difficult sharks to study, this timely book recognizes a new sophisticated focus on the White Shark, raising its status from obscurity to enlightenment. The Global Perspectives on the Biology and Life History of the White Shark celebrates the White Shark as the most studied shark in the sea. Within the chapters one can find new insights into a vast range of topics, such as behavior, physiology, migration patterns, habitat preferences, daily activity patterns, molecular genetics, reproductive biology and new research methods. The book also delves into population monitoring and policy options for managers and researchers.

Book Description
For hundreds of years, the New England cod fishery was one of the most productive in the world, with higher average annual landings than any comparable ocean area. But in the late 1980s, fish catches dropped precipitously, as the cod, flounder, and other species that had long dominated the region seemed to lose their ability to recover from the massive annual harvests. Even today, with fishing sharply restricted, populations have not recovered. Largely overlooked in this disaster is the intriguing human and scientific puzzle that lies at its heart: an anguished, seemingly inexplicable conflict between government scientists and fishermen over how fish populations are assessed, which has led to bitter disputes and has crippled efforts to agree on catch restrictions. In The Great Gulf, author David Dobbs offers a fascinating and compelling look at both sides of the conflict. With great immediacy, he describes the history of the fisheries science in this most studied of oceans, and takes the reader on a series of forays over the Gulf of Maine and Georges Bank on both fishing boats and research vessels. He introduces us to the challenges facing John Galbraith, Linda Despres, and Jay Burnett, passionate and dedicated scientists with the National Marine Fisheries Service who spend countless hours working to determine how many fish there really are, and to the dilemma of Dave Goethel, a whipsmart, conscientious fisherman with 20 years's experience who struggles to understand the complex world he works in while maintaining his livelihood in an age of increasing regulation. Dobbs paints the New England fishery problem in its full human and natural complexity, vividly portraying the vitality of an uncontrollable, ultimately unknowable sea and its strange, frightening, and beautiful creatures on the one hand, and on the other, the smart, irrepressible, unpredictable people who work there with great joy and humor, refusing to surrender to the many reasons for despair or cynicism. For anyone who read Cod or The Perfect Storm, this book offers the next chapter of the story -- how today's fishers and fisheries scientists are grappling with the collapse of this fishery and trying to chart, amid uncertain waters, a course towards its restoration.

Book Description
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.
