Pacific Salmon Life Histories gives detailed descriptions of the different life phases through which each of the seven species pass. Each chapter is written by a scientist who has spent years studying and observing a particular species of salmon. Some of the topics covered are geographic distribution, transplants, freshwater life, ocean life, development, growth, feeding, diet, migration, and spawning behaviour. The text is richly supplemented by numerous maps, illustrations, colour plates, and tables and there is a detailed general index, as well as a useful geographic index. This volume brings together for the first time, and in a comprehensive form, most of the available biological information on the seven species of Pacific salmon. It is an invaluable source of information for students and teachers of biology and fisheries science, people in the fishing and aquaculture industry, and interested laypersons in countries of the North Pacific and elsewhere.

Manipulation of the microbial gut content of farmed fishes and crustaceans can have a marked effect on their general health, growth, and quality. Expertly covering the science behind the use of prebiotics and probiotics this landmark book explains how the correct manipulation of the gut flora of farmed fishes and crustaceans can have a positive effect on their health, growth rates, feed utilization, and general wellbeing. Aquaculture Nutrition: Gut Health, Probiotics and Prebiotics provides a comprehensive overview of the current knowledge of the gut microbiomes of fish and their importance with respect to host-fish health and performance, providing in-depth, cutting-edge fundamental and applied information. Written by many of the world s leading authorities and edited by Dr Daniel Merrifield and Professor Einar Ringo, this important book discusses in detail the common mechanisms for modulating microbiomes, particularly at the gut level (e.g. probiotics, prebiotics and synbiotics). The book is a key resource for an understanding of the historical development of these products, their known mechanisms of action and their degree of efficacy as presently demonstrated in the literature. The fundamental material provided on the gut microbiota itself, and more broad aspects of microbe-live feed interactions, provide essential reading for researchers, academics and students in the areas of aquaculture nutrition, fish veterinary science, microbiology, aquaculture, fish biology and fisheries. Those involved in the development and formulation of aquaculture feeds and those with broader roles within the aquaculture industry will find a huge wealth of commercially-important information within the book s covers. All libraries in universities and research establishments where biological sciences, nutrition and aquaculture are studied and taught, should have copies of this excellent book on their shelves.

The world's marine fisheries are in trouble, as a direct result of overfishing and the overcapacity of fishing fleets. Despite intensive management efforts, the problems still persist in many areas, resulting in many fisheries being neither sustainable nor profitable. Using bio-economic models of commercial fisheries, this book demonstrates that new management methods, based on individual or community catch quotas, are required to resolve the overfishing problem. Uncertainty about marine systems may be another factor contributing to overfishing. Methods of decision analysis and Bayesian inference are used to discuss risk management and the precautionary principle, arguing that extensive marine reserves may be the best way to protect fisheries, alongside a controlled catch quota system. This book will be of interest to environmental scientists, economists and fisheries managers, providing novel insights into many well-known but poorly understood aspects of fisheries management.

Humans generate millions of tons of waste every day. This waste is rich in water, nutrients, energy and organic compounds. Yet waste is not being managed in a way that permits us to derive value from its reuse, whilst millions of farmers struggle with depleted soils and lack of water. This book shows how resource recovery and reuse (RRR) could create livelihoods, enhance food security, support green economies, reduce waste and contribute to cost recovery in the sanitation chain.

While many RRR projects depend on subsidies and hardly survive their pilot phase, hopeful signs of viable approaches to RRR are emerging around the globe including low-and middle-income countries. Many of these new commercial pathways are being charted in the informal sector, delivering innovative approaches for cost-recovery. These enterprises or projects are tapping into entrepreneurial initiatives and public-private partnerships, leveraging private capital to help realize commercial and/or social value, shifting the focus from treatment for waste disposal to treatment of waste as a valuable resource for safe reuse.

The book provides a compendium of these success stories of resource recovery and reuse. It presents for energy, nutrient and water recovery innovative business models based on approximately 70 empirical cases from around the world, each described and evaluated in a systematic way. The focus is on municipal or agro-industrial waste and models with potential for large-scale out- and up-scaling. For each model, safety concerns and risk mitigation measures are highlighted. This is the first book on business models and their enabling environment for the reuse-oriented sanitation sector.

Like other books in the Laboratory Animal Pocket Reference Series, this guide covers all aspects pertaining to the use of these organisms including their basic biology, humane care and management, husbandry, life support systems, regulatory compliance, technical procedures, veterinary care, and water quality management. In the relatively brief span of only a few decades, the zebrafish has gone from being mainly a hobby fish to a mainstream model animal employed by scientists to study everything from stem cells to the basis of behavioral changes induced by drug addiction. This rapid advance has been fueled largely by numerous and impressive advances in technology, along with detailed characterization of the animal on a genetic and molecular level. These developments have allowed scientists to leverage the many advantages of the zebrafish system to address many important questions in biology and human genetics and disease. However, there are few accepted and established standards for husbandry, management, and care for the fish in laboratory settings and even fewer comprehensive and constantly reliable resources. To this end, the goal of this handbook is to provide managers, veterinarians, investigators, technicians, and regulatory personnel with a concise yet thorough reference on zebrafish biology, care, husbandry, and management. The aim of the book is not to set standards, but rather to arm those working with the fish with scientifically grounded principles and fundamental information that can be used to design sound fish care programs. This handbook is organized into seven chapters: Biology Husbandry Life Support Systems Management Veterinary Care Experimental Methodology Resources The final chapter, Resources, provides the zebrafish user with lists of sources of additional information on the zebrafish model, as well as key references, professional organizations, and suppliers of equipment and supplies used in zebrafish husbandry and care.

The authors are two of the best taxonomic experts in crustacean decapods, who have established the actual taxonomy and systematic of numerous and important groups of decapods. They have introduced new views and approaches on the taxonomy, phylogeny and biogeography of these crustaceans. This international edition adds diagnoses and identification keys to all world families and genera: this information simply doesn't exist in any other book. During the last decade, the world register of marine species (WORMS) has created the list of known species and promoted the publication of numerous compilations on crustacean decapods. However, except specialists of each taxa, very few colleagues can identify correctly the new families and genera - there are no keys to these new groups. This book is the first to contain these world keys and is therefore a life rope for students, marine biologists, taxonomists and naturalists. The mixture of taxonomic line drawings, color illustrations and images of real-life specimens is extremely helpful for identification, especially when working in the field.

'A wonderful and important book, that from its first pages draws the reader along on a fascinating, gripping, often funny journey.' Robert Macfarlane, bestselling author of Underland. An idiosyncratic history of our island story told through five iconic fish On these rain-swept islands in the North Atlantic man and fish go back a long way. Fish are woven through the fabric of the country's history: we depend on them - for food, for livelihood and for fun - and now their fate depends on us in a relationship which has become more complex, passionate and precarious in the sophisticated 21st Century. In Silver Shoals Charles Rangeley-Wilson travels north, south, east and west through the British Isles tracing the histories, living and past, of our most iconic fish - cod, carp, eels, salmon and herring - and of the fishermen who catch them and care for them. In the company of trawlermen, longshoremen, conservationists and anglers Charles goes to sea in a trawler, whiles away hot afternoons setting eel nets, tries to bag his first elusive carp and drifts for herring on Guy Fawkes night as fireworks starburst the sky. Underscoring this journey is a fascinating historical exploration of these creatures that have shaped our island story. We learn how abundant and valued these fish were centuries before our current crisis of over-fishing: we learn how eels built our monasteries, how cod sank the Spanish Armada, how fish and chips helped us through two World Wars. Of course there is a deeper environmental dimension to the story, but Charles' optimistic perspective is this: no one is more invested in fish than the fishermen whose lives depend on them. If we can find a way to harness that passion then the future of fish and fishermen in Britain could be as extraordinary as its past.

The book Fisheries Resource Conservation discusses contemporary issues affecting global fish populations. This book describes insufficient conservation measures, jurisdictional disputes and illegal fishing vessels as some of the issues that threaten fish stocks. It stresses that there's an urgent need to adopt sustainable fishing practices, since communities that depend on fishery resources risk having their livelihoods stopped when fish populations are threatened. This book mentions the impact of globalization on local fish stocks, where the influx of external fishing boats into coastal waters has severely affected some countries' ability to fulfill domestic demand for the commodity. People must understand the importance of preserving fish populations if it's to be used as a long-term food resource.

As Four Thousand Hooks opens, an Alaskan fishing schooner is sinking. It is the summer of 1972, and the sixteen-year-old narrator is at the helm. Backtracking from the gripping prologue, Dean Adams describes how he came to be a crew member on the Grant and weaves a tale of adventure that reads like a novel--with drama, conflict, and resonant portrayals of halibut fishing, his ragtag shipmates, maritime Alaska, and the ambiguities of family life. At sea, the Grant's crew teach Dean the daily tasks of baiting thousands of longline hooks and handling the catch, and on shore they lead him through the seedy bars and guilty pleasures of Kodiak. Exhausted by twenty-hour workdays and awed by the ocean's raw power, he observes examples of human courage and vulnerability and emerges with a deeper knowledge of himself and the world. Four Thousand Hooks is both an absorbing adventure story and a rich ethnography of a way of life and work that has sustained Northwest families for generations. This coming of age story will appeal to readers including young adults and anyone interested in ocean adventures, commercial fishing, maritime life, and the Northwest coast.

The work, education, and health concerns of Canada's increasing population of fisherwomen--rural women who work on inshore fishing boats to supplant family income lost to fish plant closures--are profiled in this study of how women's work in previously male-dominated trades impact their identity and autonomy. Narratives from fisherwomen and statistics about the fishing workforce inform this gender analysis of how vocational restructuring challenges traditional patriarchal codes. The complex joys, struggles, and dangers that fisherwomen encounter shed light on this sociological transition.
