Book Description
That one could “walk drishod on the backs” of schools of salmon, shad, and other fishes moving up Atlantic coast rivers was a not uncommon kind of description of their migratory runs during early Colonial times. Accounts tell of awe-inspiring numbers of spawners pushing their way upriver, the waters “running silver,” to complete life cycles that once replenished critical marine fisheries along the Eastern Seaboard. This is a hugely important, fascinating, and unique look at the fish of North America whose history and life-cycles and conservation challenges are poorly understood. Despite these primordial abundances, over the centuries these stocks were so stressed that virtually all are now severely depressed, with many biologically or commercially extinct and some simply forgotten. Running Silver will tell the story of the past, present and future of these sea-river fish. This important book will elevate public consciousness of the contrasts between the historical and the present to show the enormous legacy that has already been lost and to help inspire efforts to save what remains. Drawing on the author's thirty-year career as a scientist and educator with a passion for the native river fish of the North East, Running Silver tells the story of these endangered fish with a mix of research, historical accounts, anecdotes, personal experience, interviews, and images.

Book Description
Genomics has revolutionized biological research over the course of the last two decades. Genome maps of key agricultural species have offered increased understanding of the structure, organization, and evolution of animal genomes. Building upon this foundation, researchers are now emphasizing research on genome function. Published with the World Aquaculture Society, Functional Genomics in Aquaculture looks at the advances in this field as they directly relate to key traits and species in aquaculture production. Functional Genomics in Aquaculture opens with two chapters that provide a useful general introduction to the field of functional genomics. The second section of the book focuses on key production traits such as growth, development, reproduction, nutrition, and physiological response to stress and diseases. The final five chapters focus on a variety of key aquaculture species. Examples looking at our understanding of the functional genomes of salmonids, Mediterranean sea bass, Atlantic cod, catfish, shrimp, and molluscs, are included in the book. Providing valuable insights and discoveries into the functional genomes of finfish and shellfish species, Functional Genomics in Aquaculture, will be an invaluable resource to researchers and professionals in aquaculture, genetics, and animal science.

Book Description
From an award–winning journalist, a “beautifully illustrated” book describing “the most pivotal moments . . . in the climate’s rich . . . 4.5 billion-year history.” (The Washington Post) Colorful and captivating, Weather: An Illustrated History hopscotches through 100 meteorological milestones and insights, from prehistory to today’s headlines and tomorrow’s forecasts. Bite-sized narratives, accompanied by exciting illustrations, touch on such varied topics as Earth’s first atmosphere, the physics of rainbows, the deadliest hailstorm, Groundhog Day, the invention of air conditioning, London’s Great Smog, the Year Without Summer, our increasingly strong hurricanes, and the Paris Agreement on climate change. A groundbreaking work by prominent environmental journalist and author Andrew Revkin, Weather: An Illustrated History presents an intriguing history of humanity’s evolving relationship with Earth’s dynamic climate system and the wondrous weather it generates. “FINALLY, someone has done something about the weather. Andrew Revkin and Lisa Mechaley have given us a startlingly fascinating book about how weather got the way it is, and how we’ve reacted to it, used it, and even helped shape it. There are a hundred captivating stories in this book that are as enlightening as they are fun. Reading them is like seeing the clouds part and the sun come out.” —Alan Alda, longtime host of Scientific American Frontiers and a founder of the Alan Alda Center for Communicating Science at Stony Brook University ”Informative, addictively readable . . . Highly recommended.” —Nathaniel Philbrick, National Book Award winner for In the Heart of the Sea: The Tragedy of the Whaleship Essex ”A gift of a book—at once fascinating, informative, and surprising.” —Elizabeth Kolbert, Pulitzer Prize–winning author of The Sixth Extinction

Book Description
This volume presents a synthesis of basic biological and conservation data for more than 30 species of sturgeons (Acipenseridae), paddlefishes (Polyodontidae) and their fossil allies in the order Acipenseriformes. Since the Jurassic, the four families of sturgeon-like fish have been restricted to the Holarctic, where until very recently they flourished in most major river systems. Today, however, virtually all species of sturgeons and paddlefishes face difficult conservation issues. Papers in the first section of this volume examine paleontology, systematics, evolution and basic biology of Acipenseriformes. The second section of this volume details current conservation status for most of the world's living species of Acipenseriformes. These papers mark the first attempt to make such a global review of recent data from across the northern hemisphere. The emerging picture is discouraging, for negative anthropogenic impacts range from overfishing to water pollution, to dams and water diversion projects, and all species are threatened to some degree. The third section of the volume considers specific human impacts and responses to conservation issues. These include: the Aral Sea ecological disaster and its impact on native sturgeons; a review of methods for restoring sturgeon populations; the use of molecular techniques in developing conservation strategies; the extreme sensitivity of sturgeons and paddlefishes to overfishing; and the history of a recently convicted caviar poaching ring. The volume's summary reviews the status of all extant species and notes future directions for research on behavior, ecology and population biology that could lead to better co-ordinated international conservation efforts.

Book Description
Two events have recently improved the prospects of protecting fish and their environment in Switzerland: the acceptance of a new Federal Water Protection Law in the plebiscite of May 17th 1992, and the new Federal Legislation on Fisheries, in force since January 1st 1994. With this legal framework, the possibilities for protection of nature and landscape have now considerably improved in Switzerland. The most important aims of the Federal Law on Water Protection are to safeguard the natural habitats of the native flora and fauna and water as the habitat of aquatic organisms. This includes not only the preservation or restoration of water quality in lakes and rivers, but also, in rivers used for hydroelectricity, irrigation or as industrial or other water supplies, the maintenance of sufficient water to fulfill the minimal requirements for fish. However, good quality water in sufficient quan tities alone is not enough to guarantee the survival of fish. Intact fish habitats comprise various phYsical structures including plenty of hiding places, hunting grounds, reproduction and nursery areas within suitable distances from each other. This third aspect of conservation and restoration of aquatic habitats is a central point in the new Federal Law on Fisheries. Whereas the former versions of this law were more concerned with fishery regulations, the recent legislation defines new areas of responsibility for the federal and the cantonal governments.
