The most comprehensive field guide ever compiled for identifying reef fishes from the Gulf of California to the Pacific coast of Panama, including offshore islands. Over 500 photographs of 400 species taken in their natural habitat. The book is dedicated to Baja Legend Alex Kerstitch and includes several of his drawings and photographs. The concise text accompanying each species portrait includes the fishs common, scientific and family names, size range, description, visually distinctive features, preferred habitat, typical behaviour, depth range, and geographical distribution.

Nudibranchs are among the most beautiful creatures on the reef, with colors and shapes that dazzle and delight. Unlike fish that may disappear before our eyes in a flash, the showy nudibranchs glides slowly along the substrate, allowing us the time to savor this extraordinary sight. With their shell-less unprotected, bodies how do they survive in seas filled with hungry mouths? How do these sightless creatures navigate the reefs to find food and mates? What and how do they eat? How do they reproduce? What special relationships have they developed with other reef inhabitants? These and many more questions are answered in this informative and lavishly illustrated book. You will never look at a nudibranch the same way again.

There are nearly 1,000 species of freshwater fishes in North America alone, and identifying them can sometimes be a daunting task. In fact, in just the twenty years since publication of the first edition of the "Peterson Field Guide to Freshwater Fishes," the number of species has risen by almost 150, including 19 marine invaders and 16 newly established nonnative species. This second edition incorporates all of these new species, plus all-new maps and a collection of new and revised plates. Some of the species can be told apart only by minute differences in coloration or shape, and these beautifully illustrated plates reveal exactly how to distinguish each species.
The guide includes detailed maps and information showing where to locate each species of fish--whether that species can be found in miles-long stretches of river or small pools that cover only dozens of square feet. The ichthyologic world of the twenty-first century is not the same as it was in the twentieth, and this brand-new edition of the definitive field guide to freshwater fishes reflects these many changes.

Trundling along in essentially the same form for some 220 million years, turtles have seen dinosaurs come and go, mammals emerge, and humankind expand its dominion. Is it any wonder the persistent reptile bested the hare? In this engaging book physiologist Donald Jackson shares a lifetime of observation of this curious creature, allowing us a look under the shell of an animal at once so familiar and so strange. Here we discover how the turtle's proverbial slowness helps it survive a long, cold winter under ice. How the shell not only serves as a protective home but also influences such essential functions as buoyancy control, breathing, and surviving remarkably long periods without oxygen, and how many other physiological features help define this unique animal. Jackson offers insight into what exactly it's like to live inside a shell-to carry the heavy carapace on land and in water, to breathe without an expandable ribcage, to have sex with all that body armor intervening. Along the way we also learn something about the process of scientific discovery-how the answer to one question leads to new questions, how a chance observation can change the direction of study, and above all how new research always builds on the previous work of others. A clear and informative exposition of physiological concepts using the turtle as a model organism, the book is as interesting for what it tells us about scientific investigation as it is for its deep and detailed understanding of how the enduring turtle "works."

Marine researchers are discovering new ocean creatures every day, especially at its deepest depths. From the author of Creatures of the Deep, Encyclopedia of Whales, Dolphins and Porpoises and other books about the ocean and the animals that live there, comes a new title about some of the most unusual marine life forms. The book organizes the creatures into three parts based on where they live in the ocean. Each part has representatives from the various marine animal classes (e.g., fish, crustaceans, jellyfish and siphonophores, squids, tunicates and other invertebrates). Informative captions accompany the 90 gorgeous photographs of otherworldly creatures. Part 1: Surface Waters of the Ocean at Night: The Blackwater Vertical Migrators. In images taken by dedicated blackwater photographers Linda Ianniello and Susan Mears, these mostly larval creatures haunt the near-surface waters making vertical migrations every night to feed. Part 2: Middle to Deep Dark Waters: Masters of the Language of Light. In this perpetual night, survival is a matter of being able to understand and process light signals, some in different colours, some flashing, some faint - the most sophisticated use of bioluminescence on Earth. The sea creatures here are small with big eyes and even larger mouths with extraordinarily sharp teeth; Photographer David Shale travelled with BBC Blue Planet and other expeditions to photograph these deep sea creatures, while photographers Solvin Zankl, Alexander Semenov and others brought their own dedication to expeditions in the Pacific, Indian, Atlantic and Arctic oceans. Part 3. The Continental Shelf to the Abyssal Plain: The Bottom Dwellers. This bottom of the sea has fewer fish, and is populated by such alien-like creatures as no-eyed or tripod fish, sea cucumbers, as well as basket stars, crabs, and worms with species varying by depth and location. The introduction to each part of the book describes what makes the ocean waters at that depth unique, and why it is home to specific types of sea life. The photographs were taken in the ocean by expert divers and submariners, most of whom are both scientists and underwater photographers. The images display the creatures vividly against a background as black as the ocean depths.

Fish nutrition can be the deciding factor between a robust and healthy farmed fish population and low aquaculture production. In an age where chemicals and antibiotics are under greater scrutiny than ever, a strong understanding of the role of nutrients and feed additives is essential in the aquaculture industry. Dietary Nutrients, Additives and Fish Health is a comprehensive review of dietary nutrients, antinutritional factors and toxins, and non-nutrient dietary additives, and their effects on fish performance and immune system function, as well as overall health. The book opens with an overview of fish immune systems and health. Subsequent chapters delve into proteins and amino acids, lipids and fatty acids, carbohydrates, beta glucans, vitamins, minerals, antinutrients, mycotoxins, nucleotides, prebiotics, probiotics, organic acids and their salts, and plant extracts and their impacts on fish health, growth, and development. The text then concludes with a chapter on feeding practices. Authored by leaders in aquaculture, Dietary Nutrients, Additives and Fish Health will be an invaluable resource to graduate students, researchers and professionals alike.

Combining natural history with beguiling autobiographical and historical narrative, To Sea and Back is a dazzling portrait of a fish whose story is closely intertwined with our own. 'Indispensable and powerful... To Sea and Back mingles history with biography and science... Shelton writes with a poet's ear... A writer to be prized.'-- Tom Adair, Scotsman The Atlantic salmon is an extraordinary and mysterious fish. In To Sea and Back, Richard Shelton combines memoir and deep scientific knowledge to reveal, from the salmon's point of view, both the riverine and marine worlds in which it lives. He explores this iconic fish's journey to reach its feeding grounds in the northern oceans before making the return over thousands of miles to the burns of its birth to reproduce. Along the way, Shelton describes the feats of exploration that gave us our first real understanding of the oceans, and shows how this iconic fish is a vital indicator of the health of our rivers and oceans. Above all, To Sea and Back is the story of Richard Shelton's lifelong passion for the sea and his attempt to solve the perennial enigmas of the salmon's secret life.

An engaging account of the natural history of rock and boulder-strewn shores around Britain's coastline Rocky Shores explores the species, communities and landscape of the narrow strip of land surrounding much of the British Isles. While it may be limited in extent, this habitat is incredibly biodiverse, and this insightful book details all the patterns of marine life that might be encountered on sheltered and exposed shores, from the inhospitable splash zone to the repeatedly submerged lower shore, and everything in between. Comprehensive chapters accompanied by exceptional photographs cover various members of the rocky-shore community in turn: striking lichens that colourfully adorn the rocks; seaweeds that have sustained human settlements for millennia; mysterious and often spectacular worms and their relatives; molluscs with variously configured shells; spiny-skinned echinoderms that move using tube feet; arthropods that range from tiny marine insects to heavy-clawed crabs; and microscopic species that drift around at the mercy of the tides. Rock pools provide pockets of diversity dotted across the shore, while the strandline at the high-tide mark supports a unique assemblage of microbes and invertebrates that attracts a variety of birds and mammals. For anyone with a love of the shore - from the occasional rockpooler to avid naturalists - this book is a must for your collection.

This volume explores nonhuman animals’ involvement with human maritime activities in the age of sail—as well as the myriad multispecies connections formed across different geographical locations knitted together by the long history of global ship movement. Far from treating the ship as a confined space defined by the sea, Maritime Animals considers the ship’s connections to broader contexts and networks and covers a variety of locations, from the Canadian Arctic to the Pacific Islands. Each chapter focuses on the oceanic experiences of a particular species, from ship vermin, animals transported onboard as food, and animal specimens for scientific study to livestock, companion and working animals, deep-sea animals that find refuge in shipwrecks, and terrestrial animals that hunker down on flotsam and jetsam. Drawing on recent scholarship in animal studies, maritime studies, environmental humanities, and a wide range of other perspectives and storytelling approaches, Maritime Animals challenges an anthropocentric understanding of maritime history. Instead, this volume highlights the ways in which species, through their interaction with the oceans, tell stories and make histories in significant and often surprising ways. In addition to the editor, the contributors to this volume include Anna Boswell, Nancy Cushing, Lea Edgar, David Haworth, Donna Landry, Derek Lee Nelson, Jimmy Packham, Laurence Publicover, Killian Quigley, Lynette Russell, Adam Sundberg, and Thom van Dooren.

Salmon are one of the most popular and commonly eaten fish and are among the most important fishery resources in the world. They are born and die in fresh water but can live in both fresh water and seawater where they migrate between rivers and oceans, showing amazing abilities to home to their natal stream precisely. However, their dynamic life cycles and mysterious abilities of natal stream imprinting and homing migration are not well understood. Physiological Aspects of Imprinting and Homing Migration in Salmon: Emerging Researches and Opportunities is a pivotal reference source that introduces the dynamic and complicated life cycle of salmon connected with fish migration and climate changes and presents physiological mechanisms of natal stream imprinting and homing in salmon with special references to hormone, olfaction, memory, and behavior. Additionally, salmon resources concerning salmon commercial fisheries, aquaculture, and global propagation systems are discussed. This book is ideally designed for ichthyologists, environmentalists, pisciculture professionals, fisheries, marine biologists, scientists, researchers, academicians, and students seeking coverage on one of the most integral species of fish in the world.
