Book Description
Alaska Herring History is a thoroughly researched, well-documented, and comprehensive chronicle of Alaska’s herring fisheries. Author James Mackovjak describes the evolution of these fisheries from the late nineteenth century to the present, including harvest, processing, markets, and sustained-yield management considerations. The book is divided into three parts based on the purposes for which herring have been harvested. Part I is a history of the reduction (fertilizer/fish meal/fish oil) and cured (salted) herring industries and the bait-herring fisheries; part II is a history of the roe-herring fisheries in Southeast Alaska, Prince William Sound, Kodiak Island, lower Cook Inlet, Togiak, and Norton Sound; and part III is a history of the herring spawn-on-kelp industry. Historical and contemporary photos and illustrations—as well as graphs and charts that help summarize the development and, in some cases, the demise of the fisheries—augment this detailed look at the evolution of Alaska's herring fisheries. Balancing scientific details, historical facts, and personal anecdotes from experts in the field, Alaska Herring History will be of interest to historians, social scientists, biologists, and fishery managers and makes an important contribution to Alaska fisheries literature.

Book Description
In this book, the editors present a view of the socioecology of primates and cetaceans in a comparative perspective to elucidate the social evolution of highly intellectual mammals in terrestrial and aquatic environments. Despite obvious differences in morphology and eco-physiology, there are many cases of comparable, sometimes strikingly similar patterns of sociobehavioral complexity. A number of long-term field studies have accumulated a substantial amount of data on the life history of various taxa, foraging ecology, social and sexual relationships, demography, and various patterns of behavior: from dynamic fission–fusion to long-term stable societies; from male-bonded to bisexually bonded to matrilineal groups. Primatologists and cetologists have come together to provide four evolutionary themes: (1) social complexity and behavioral plasticity, (2) life history strategies and social evolution, (3) the interface between behavior, demography, and conservation, and (4) selected topics in comparative behavior. These comparisons of taxa that are evolutionarily distant but live in comparable complex sociocognitive environments boost our appreciation of their sophisticated mammalian societies and can advance our understanding of the ecological factors that have shaped their social evolution. This knowledge also facilitates a better understanding of the day-to-day challenges these animals face in the human-dominated world and may improve the capacity and effectiveness of our conservation efforts.

Book Description
It is now clear that data based on the studies of fish eggs and larvae make a number of unique contributions to fishery science that are crucial for accurate assessment and management of fish populations, including those of commercially important fisheries. This valuable book demonstrates why fish eggs and larvae are important, how the characteristics of early life stages require a somewhat different research approach and how information on early life stages can be applied and interpreted to yield unique insights into fish populations. The editors of Fishery Science have drawn together an extremely useful and well-written book with contributions from internationally respected researchers from North America, Asia and Europe. Chapters include a discussion of the unique nature of early life stages, age and growth, mortality, recruitment, populations analysis, habitats, human impacts and management. A carefully selected set of case studies demonstrates several specific applications of early life history information to a number of fishery problems. Fishery Science was designed to complement existing textbooks and is an essential purchase for all fisheries students and professionals, and for biologists working on the early life stages of fish. This exciting book is also of great value to ecologists, marine, freshwater and environmental scientists, populations biologists and oceanographers. All libraries in universities and research establishments where biological and fishery science are studied and taught should have copies of this book available on their shelves.

Book Description
Fish recruitment is a key process for maintaining sustainable fish populations. In the marine environment, fish recruitment is carried out in many different ways, all of which have different life history strategies. The objective of this book is to argue for greater linkages between basic and applied research on fisheries recruitment, and assessment and management of exploited fish stocks. Following an introductory chapter, this second edition of Fish Reproductive Biology is organized into 3 main sections: Biology, Population Dynamics and Recruitment Information Critical to Successful Assessment and Management Incorporation of Reproductive Biology and Recruitment Considerations into Management Advice and Strategies The authors collectively bring a wide range of diverse experience in areas of reproductive biology, fisheries oceanography, stock assessment, and management. Fully updated throughout, the book will be of great interest to a wide audience. It is useful as a textbook in graduate and undergraduate courses in fisheries biology, fisheries science, and fisheries resource management and will provide vital information for fish biologists, fisheries scientists and managers.

Book Description
Meet the woman whose life revolves around orca, or killer whales. This book tells the fascinating story of Dr Ingrid Visser, a marine scientist who has spent the past ten years studying these creatures. During this time she has got to know many New Zealand orca intimately; she calls them her friends and can identify some by sight. Ingrid has a hands-on approach to her study - getting into the water with them, watching them hunt and interacting in any way she can. Ingrid is the only person to work with orca in the South Pacific and has discovered many differences between their behaviour here and in the northern hemisphere. The book is packed with interesting facts about orca in New Zealand and also tells Ingrid's own personal story and the inspiring encounters she has had with these intriguing animals.

Book Description
Science entwines with matters of the human heart as a whale researcher chronicles the lives of an endangered family of orcas Ever since Eva Saulitis began her whale research in Alaska in the 1980s, she has been drawn deeply into the lives of a single extended family of endangered orcas struggling to survive in Prince William Sound. Over the course of a decades-long career spent observing and studying these whales, and eventually coming to know them as individuals, she has, sadly, witnessed the devastation wrought by the Exxon Valdez oil spill of 1989—after which not a single calf has been born to the group. With the intellectual rigor of a scientist and the heart of a poet, Saulitis gives voice to these vital yet vanishing survivors and the place they are so loyal to. Both an elegy for one orca family and a celebration of the entire species, Into Great Silence is a moving portrait of the interconnectedness of humans with animals and place—and of the responsibility we have to protect them.
