Salmon, one of the most determined, single-minded creatures on earth, have for hundreds of thousands of years succeeded in returning from the sea to their birth rivers to spawn - no matter the conditions or obstacles. But in recent years increasingly fewer are returning due to steady incursions into their habitat from dams, industry, and climate change. The salmon of the Pacific Rim are set for near extinction, just like the salmon that once filled the Atlantic Ocean.

Stronghold is an enthralling account of an unlikely visionary, Guido Rahr, and his mission to protect the world s last bastion of wild salmon. The reader is taken on wild and at times dangerous adventure, as we follow him from Oregon to Alaska to one of the world s last remaining wildernesses, in the Russian Far East - a landscape of ecological richness and diversity that is rapidly being developed for oil, gas, minerals, and timber.

As Guido befriends and navigates scientists, conservationists, corrupt officials, Russian oligarchs, unexpected allies, and impenetrable bureaucracies, he reveals the astonishing natural history of the endangered salmon, a species whose demise will reverberate across the planet. And he sets into motion a plan that can secure their survival.

The text is written for an audience of amateur and professional ichthyologists, sportsmen, and fishermen, based on new revisions, original research, and critical reviews of existing information. Species are illustrated by exceptional black and white line drawings, accompanied by distribution maps and tables of meristic data. Distributed for the Yale Peabody Museum of Natural History

The Fishes of the Western North Atlantic series, which began publication in the 1940s by Yale University's Sears Foundation for Marine Research, was from its beginnings conceived to synthesize and make accessible the wealth of information in widely scattered published accounts of the fish fauna of the region for both the layman and the specialist, presenting critical reviews rather than compilations. These reference works are still considered valuable and of interest today to both general audiences and the academic community. As described in the Preface to the first volume, the series was "written on the premise that it should be useful to those in many walks of life-to those casually ... interested ..., to the sportsman ..., to the fisherman ..., as well as to the amateur ichthyologist and the professional scientist." These books remain authoritative studies of the anadromous, estuarine, and marine fishes of the waters of the western North Atlantic from Hudson Bay southward to the Amazon, ranking as primary references for both amateurs and professionals interested in fishes, and as significant working tools for students of the sea.

This book gathers current data on the two types of fish metamorphoses and their endocrine controls. It will be of interest for fish biologists as well as comparative physiologists and endocrinologists. Metamorphosis is a major developmental phase characterized by morphological and physiological changes. It prepares organisms for a drastic shift in habitat and behavior. Among vertebrates, besides the well-known larval metamorphosis in amphibians, two types of metamorphosis are also described in the life cycle of some fish species. Larval metamorphosis, also called first metamorphosis or true metamorphosis, is encountered in lampreys, representative species of basal vertebrates as well as in some teleost groups, elopomorphs and pleuronectiforms, and possibly also in some other teleost species. Secondary metamorphosis occurs in juveniles of some diadromic migratory teleosts, such as salmons and eels, and compared to larval metamorphosis, involves less drastic morphological changes.

In this book, similar species are compared which is an interesting aid to certain identification. Each species account is alive with information as to habits and diets, interesting behaviour patterns, reproduction and larval forms, colour variations, poisonous species and more. There is related information as to line-fishing and bait. The worldwide distribution of these fish is given making it interesting beyond the Southern African coast.

This title will appeal to academics, students, anglers, divers, aquarists, ichthyologists and all ocean enthusiasts. There are 400 species accounts which are accompanied by exquisite colour paintings which assist in identification.

Damselfishes (Pomacentridae) are highly conspicuous, diurnal inhabitants of mainly reef areas, capturing the attention of many scientists. Their high diversity and the many interesting characteristics dealing with their way of life (sound production, breeding biology, sex change, farming and gregarious behavior, settlement, diet, habitat) easily explain how this group is continually kept in the limelight and is the subject of numerous studies. This book gathers the data dealing with damselfish morphology, physiology, behavior, ecology and phylogeny.It contains 14 chapters written by renowned scientists.

Beach-spawning fishes from exotic locations on most continents of the world provide spectacular examples of extreme adaptations during the most vulnerable life cycle stages. The beauty, intriguing biology, and importance of these charismatic fishes at the interface of marine and terrestrial ecosystems have inspired numerous scientific studies. Adaptations of behavior, physiology, development, and ecology are gathered together for the first time in this book. Beach-Spawning Fishes: Reproduction in an Endangered Ecosystem is a comprehensive guide to beach spawning, a charismatic animal behavior that is seen in a surprising number of teleost species. This unexpected form of reproduction provides a window into the ecology of coastal areas, the behaviors and physiology necessary for fishes and their eggs to adapt to terrestrial conditions, and the threats and challenges for conservation and management. Beach-spawning species include important forage fishes such as the capelin, exotic fishes such as the fugu puffer, and the spectacular midnight runs of the California grunion.

Most of what we do on land ends up impacting the ocean, but never is that clearer than when we look at salmon. Centuries of our greatest assaults on nature, from overfishing to dams, from hatcheries to fish farms, from industrial pollution to the ravages of climate change, can be seen in their harrowing yet awe-inspiring life cycle.

From the Pacific to the Atlantic, through Scotland, Ireland, Norway, Iceland, Japan and Siberia, Mark Kurlansky traces the history of the world through his fish-eye lens, laying bare our misdirected attempts to manipulate salmon for our own benefit. Attempts that have had a devastating impact on both fish and earth.

Now, the only way to save salmon is to save the planet, and the only way to save the planet may be to save the salmon.

This is the first comprehensive book on the biology and ecology of pufferfish, also known as blowfish, swellfish, and globefish. Covering 197 species of pufferfish recorded so far from the marine, brackish, and freshwater ecosystems of the world, this important volume expounds on the toxins and associated poisonings of pufferfish. Importantly, the volume also explores the many uses of pufferfish, such as in aquariums, for their nutritional and culinary value, and for their emerging uses in the treatment of pain. Topics covered include: biology and ecology of pufferfish profiles of the world's marine, brackish, and freshwater pufferfish species characteristics of TTX (tetrodotoxin) and STX (saxitoxin) of pufferfish pufferfish poisoning and symptoms: treatment and management aquarium uses of pufferfish nutritional and pharmaceutical values of pufferfish diseases and parasites of pufferfish and their management

This illustrated guide describes the many ways that coarse fish species depend upon the diversity of habitats in river systems and considers how this dependence changes throughout the stages of their lives - from spawning and eggs, through to the juvenile and adult stages- and with changing seasons and river conditions. This knowledge is important if we are to understand the many population bottlenecks and the variety of coarse fish species that have resulted from historic changes to our rivers. It is also important if we are to manage rivers positively to protect and improve the vitality of coarse fisheries - a process that will also benefit the wider wildlife community with which coarse fish are interdependent.

Nanotechnology offers a revolutionary and definitive approach for the efficient delivery of drug molecules to non-healthy tissues and cells. This first volume of a series of two volumes analyzes the basics in the development of drug-loaded nanoplatforms, the so-called nanomedicines. Special attention is given to physicochemical engineering, pharmacokinetics, biocompatibility and biodegradability, representative nanoplatforms (based on lipids, polymers, cyclodextrins, metals, carbon, silica, iron oxides, etc.), and advanced nano-engineering strategies for passive, ligand-mediated, and/or stimuli-sensitive drug delivery and release.

Recent advances in fish cytogenetics have enhanced the interest in chromosome analysis in both fundamental (systematics and comparative genomics among fishes and other vertebrate groups) and applied (aquaculture, conservation and response to pollutants, whole genome sequencing of model fish species) research. Although the genomic material, the chromosomes, is basically the same in the various organisms, experience has clearly shown that fish chromosomes have to be handled with specific protocols. In laboratories around the world, traditional cytogenetic techniques and molecular cytogenetics have seen a vast improvement but the technical details and protocols are often not published in scientific journals because of constraints in format and size and therefore they are not accessible to the whole scientific community. These shortcomings are very well known to fish cytogeneticists and the idea to prepare a specific manual was first discussed during the first "Workshop of Fish Cytogenetics" held in Concarneau (France), in 1992. Resulting from the above workshop, a draft compilation of the techniques and protocols in fish cytogenetics available at that time had been produced and distributed privately, but never published. There does not exist, at present, any published handbook or manual specifically dealing with fish cytogenetics. This book fills this void by bringing together and updating the main techniques so that the traditional methods can be standardized. Moreover, this book includes novel developments or improvements; some of the protocols provided here are practically unknown to the scientific community and even now unpublished.

Immunity studies in sharks over the past three decades have produced some remarkable discoveries. If one message rings true, it is that alternative animal model systems, such as sharks and their relatives, have contributed very substantially to a better understanding of the development evolution of our own immune system. Immunobiology of the Shark describes the cellular, genetic, and molecular specifics of immune systems in sharks. Diverse approaches were employed to study the immunobiology of the shark from basic microscopic observations to detailed genome annotation. The book also raises a series of fascinating questions, which can be addressed experimentally using today's technology. This book will be a valuable resource for mainstream immunologists, comparative immunologists, geneticists, ecologists, evolutionary biologists, and investigators engaged in shark research. The book also aims to illustrate the magnificence of these animals as model systems and underscores the importance of their study to further understand their complex, and often enigmatic, biology.

An understanding of gonorynchiform morphology and systematic inter- and intra-relationships has proven vital to a better understanding of the evolution of lower teleosts in general, and more specifically of groups such as the clupeiforms (e.g., herrings and anchovies), and ostariophysans (e.g., carps, minnows and catfishes). This book examines the current knowledge of gonorynchiform biology, including comparative osteology, myology, epibranchial morphology and development. Phylogenetic interrelationships among gonorynchiform fishes are reexamined.
