Book SynopsisWINNER OF A SOMERSET MAUGHAM AWARD 2021 A BBC RADIO 4 BOOK OF THE WEEK SHORTLISTED FOR THE WAINWRIGHT PRIZE A SUNDAY TIMES AND FINANCIAL TIMES BOOK OF THE YEAR 'Marks the birth of a new star of non-fiction' William Dalrymple 'A beautiful account of immersion in an alien world' Philip Marsden, Guardian There is the Cornwall Lamorna Ash knew as a child – the idyllic, folklore-rich place where she spent her summer holidays. Then there is the Cornwall she discovers when, feeling increasingly dislocated in London, she moves to Newlyn, a fishing town near Land’s End. This Cornwall is messier and harder; it doesn’t seem like a place that would welcome strangers. But before long, Lamorna finds herself on a week-long trawler trip with a crew of local fishermen, afforded a rare glimpse into their world, their warmth and their humour. Out on the water, miles from the coast, she learns how fishing requires you to confront who you are and what it is that tethers you to the land. Dark, Salt, Clear is a bracing journey of discovery and a captivating portrait of a community sustained and defined by the sea for centuries.Trade ReviewAsh gets to the salty heart of why [commercial fishing] still matters, not just to the communities in Cornwall it sustains, but for the richness and cultural heritage it represents ... Beyond the beauty of her prose, Ash’s great strength lies in her ability to capture a sense of place -- Books of the Year * Sunday Times *Part coming-of-age memoir, part anthropological study, Dark, Salt, Clear glistens with deftly told snippets and character-rich stories … Cornwall’s harbourside cottages and ragged cliffs may look picturesque, but they hide an unsettling “anger and insularity”, she argues. With graceful lyricism and endearing humility, Ash gives this rage both voice and face -- Oliver Balch * Financial Times *Terrific ... A hugely moving but unsentimental account of not only today’s fishermen but also a salty, grafting, real-life England too rarely depicted in literature ... It is well-timed, feels rather important, and has excellent tips on the filleting of fish. What more could you want? -- Richard Benson * Mail on Sunday *Lamorna Ash conjures a remarkable sense of place, her book deftly woven with a profound empathy for the people she encounters, as well as great literature, past and present. I loved this book -- Sophy Roberts, author of 'The Lost Pianos of Siberia'One of Spring’s most hotly anticipated titles -- Rachel Cooke * Observer *A beautiful account of immersion in an alien world – the tightly bound fishing community of Newlyn ... Spending weeks with fishermen on small fishing boats, and amid their equally turbulent shore life, Ash offers a sharp and poignant portrait of men living an intense and peripheral existence -- Philip Marsden * Guardian *[An] outstanding travel writing debut … If you love Cornwall for its beaches and photogenic fishing villages, you should read this captivating, true-to-life portrait of a place that, while angry and insular at times, is also fiercely proud and community-minded … Newlyn is a place with much to teach us in these times -- Caroline Sanderson * Daily Express *Beautifully written … [Ash is] an empathetic writer who sees poetry in the everyday … If you read this thoughtful and observant chronicle, you’ll never look at Cornwall in the same way again * Daily Mail *Lamorna Ash is a beautiful prose stylist – precise, perceptive, humane and sensitive – who somehow manages to write in a way that is both earthy and poetic. Her debut book – full of fish and blood and salt and oilskins – marks the birth of a new star of non-fiction -- William DalrympleI love this town and I love this book – both are imbued with the unadorned lessons of hard earned lives -- Mark KurlanskyWith the heart of a novelist and the clarity of an ethnographer, Lamorna Ash reveals the Cornish fishing community of Newlyn in all its tension and hardship and wild joy. Dark, Salt, Clear is a book of deep immersion and a stunning debut -- Philip MarsdenLamorna Ash evokes the vigour and complexity of the country’s westernmost fishing port with a love only a granite heart could resist. As Cornwall’s fishing and farming communities hold their breath to see whether leaving the EU will save or savage them, Dark, Salt, Clear arrives at the perfect time and should be cherished by natives, incomers and emmets alike -- Patrick GaleLamorna writes with a maturity and wisdom that betrays her years and which took me to the very heart of Newlyn while questioning my sense of belonging ... Dark Salt, Clear is a captivating homage to Newlyn and its people -- Lara MaiklemLamorna Ash’s beautiful debut is a seductive, vivid reading experience. A portrait of the life and unique character of a community, it is also an exploration of the spaces around a person, that make up the person – a young woman’s search for her own identity and her self. You’ll love her characters, because they’ve been written with love, and that makes them live on the page -- Barney NorrisLamorna Ash's captivating debut charts her trawler trip with Cornish fishermen, and the lessons she learned about a dying tradition and what it takes to live at sea * Vogue *[Ash] tells the riveting tale of eight days spent at sea on a trawler with a crew of fishermen. Battling homesickness and seasickness, she sets herself to this toughest and most perilous of trades, learning to haul, gut and pack fish.

Book SynopsisA lighthearted and informative narrative about the history of herring and our love affair with the silver darlings. Scots like to smoke or salt them. The Dutch love them raw. Swedes look on with relish as they open bulging, foul-smelling cans to find them curdling within. Jamaicans prefer them with a dash of chilli pepper. Germans and the English enjoy their taste best when accompanied by pickle's bite and brine. Throughout the long centuries men have fished around their coastlines and beyond, the herring has done much to shape both human taste and history. Men have co-operated and come into conflict over its shoals, setting out in boats to catch them, straying, too, from their home ports to bring full nets to shore. Women have also often been at the centre of the industry, gutting and salting the catch when the annual harvest had taken place, knitting, too, the garments fishermen wore to protect them from the ocean's chill. Following a journey from the western edge of Norway to Trade ReviewThe story is told with great charm, and tinged with a spirit of loss and yearning. * Philip Marsden, The Spectator *Mr Murray is a gregarious and engaging raconteur as he flips between the diverse aspects of this versatile little creature. * The Economist *This is a splendid book, filled with passion, wit, and wonderful facts. * Geographical magazine *...a fine, scholarly, restless and keen-brained work. -- John Macleod * Scottish Review of Books *It's a fascinating book and worth a read. * The Glasgow Herald *Like the herring, this is a book that darts across time and oceans. It gleams with story. A wonderful read. -- Sally MagnussonThese herring tales are far more tasty than you might expect. * The Scotsman *Donald S. Murray takes us to places we’ve never been before as he explores the world of herring in a sweet, pellucid, often poetic prose. -- Jay PariniHerring Tales offers a fascinating view of the coastal cultures of northern Europe, of how a 12-inch fish has affected human activity there for hundreds of years. * Philip Marsden, The Spectator *Murray's account of the herring industry has almost as many facets as his slippery subjects have scales ... and offers fillets of history, culture and zoology, with an emphasis on the eclectic. * The Economist *Herring Tales is the story of close-knit communities based around a particular kind of fishing, a world that is both present and, alas, fading. I strongly recommend this eloquent and finely detailed book. -- Jay PariniMurray is one of my favourite authors in any genre, and this quirky book on how the "silver darlings" shaped human taste and history doesn't disappoint. * Guardian *Murray mixes folklore, personal reminiscence, cookery... and intertwines herring culture with political history. -- Brian Morton * Times Literary Supplement *After reading author, poet and Gaelic playwright Donald S Murray's quirky book you may never look at the humble herring in quite the same way! * Countryside *It provides interesting facts and observations about the fish and fishing industry, it's historical and economic impact, some amusing anecdotes, and even a couple of Woody Allen jokes. * Countryside *Who knew fermented fish could be so much fun? -- Anna Burnside * Daily Record *The herring is an unsung hero in the tale of the land and the sea. Its trade brought prosperity, but herring fishing brought misery and loss too. In his lyrical voice Donald Murray sings this tale so we can fathom its depths. And, as is always the case with good poetry, all of it is true. -- Huib Stam, author of Herring: A Love StorySearch as you might, you may be reasonably assured that no other subject of the Emperor Herring will publish a better book about the reign of the silver darlings. ‘Herring Tales’ is a glorious piece of non-fiction … a fast, lively, funny and altogether irresistible book. ‘Herring Tales’ is a tour de force. It may not bring the shoals back, but it will immortalise their memory. * West Highland Free Press *Donald weaves a herring tapestry as beautiful and as intricate as a piece of Harris Tweed. * The New Shetlander *Coated in oatmeal and fried, kippered or pickled or eaten raw, the herring is the best of fish, and Donald Murray’s social, economic and cultural history of the herring fisheries of northern Europe is worthy of it, rich in observation, reflection and anecdote. It’s an entrancing work in which learning is worn lightly and an all but vanished way of life is brought vividly before us. There’s the taste of the sea in the herring and in this book. -- Allan MassieA rare and precious book which is both erudite and humane. Herring Tales takes a humble, overlooked phenomenon and shows how all of life is interwoven with it. Totally life-affirming and inspirational. -- Ewan MorrisonA fascinating, vividly written account of the role of the herring in the history, culture, folklore, festivities as well as cuisine of life all over the North Sea. The canvas is wide, and the author looks at Ireland, Scotland, Iceland, Norway, Holland, with an unexpected glance at Italy thrown in. An informative work and an enthralling read. Donald Murray shows that there is more to the herring than an accompaniment to a plate of chips on a Saturday night after an evening at the pub. -- Joseph FarrellIt is a fascinating read – written with wit and a deep rooted understanding of the subject. * fallonsangler.net *This delightful book celebrates the strong cultural bond between herring and human. * Daily Mail *Table of ContentsMap of The Major Herring Ports of Northern Europe Chapter 1: 'Them Belly Full' Chapter 2: 'When the Seagulls Follow the Travellers' Chapter 3: 'Return to Sender' Chapter 4: 'There's a Ghost in My House' Chapter 5: 'Get Off of My Cloud' Chapter 6: 'Starman' Chapter 7: 'Celebration of the Lizard' Chapter 8: 'Seven Seas of Rhye' Chapter 9: 'Blowing' in the Wind' Chapter 10: 'Dweller on the Threshold' Chapter 11: 'Spirit in the Sky' Chapter 12: 'Will You Still Love Me Tomorrow?'

Book SynopsisWherever you fit into the debate about food - vegan, vegetarian, pescatarian, flexitarian, or carnivore - you cannot argue against the fact that fish have influenced our diet for millennia, and, for many, continue to do so today. We are, after all, an island nation surrounded by seas that were once extremely rich and diverse in its variety of both fish and shellfish, and it's well known that early man was as much a hunter-gatherer on water as on land for fish are a great supplier of protein. Yet only in the last couple of centuries has fishing become an established occupation, and the last forty years has seen a multitude of change in what is now an industry.Outside the industry, little has been written about how this seafood is caught, landed and then reaches us, the consumer. We all know about fish and chip shops, but do we know the difference between a beam and otter trawl? What is the difference between a lobster pot and a lobster creel? Did you know oysters and salmon were once ca

Book SynopsisEat more fish, the doctors say. But is the salmon you are consuming really healthy? In the early 1970s, a group of scientists researched how to make more food for the growing population of the world. They looked to the sea. They sampled genes from salmon in 41 Norwegian and Swedish rivers and designed a new salmon that was fatter and faster growing. This was considered an amazing innovation and was the beginning of a new industry: salmon farming. The industry spread from coastal Norway to Scotland, Canada, Australia, Ireland, Chile, Iceland, the Faroe Islands, and the United States. Business boomed, jobs were created, and a new type of food, the farmed salmon, spread around the globe. People everywhere bought and enjoyed the abundant fish: grilled, poached, roasted, and as sushi and sashimi. They were grateful for this delicious, affordable protein. But at what cost? We now know that there were unintended consequences: some of these new fish escaped, competing for sustenance with other fish in the sea. The new fish spread diseases, salmon louse swarmed, and wild salmon stocks dwindles. In a prizewinning five-year investigation, authors Simen Sætre and Kjetil Østli took an in-depth look at Norway’s role in the global salmon industry and, for the first time, produced a comprehensive evaluation of the detrimental effects of salmon farming. From lice to escapees, from concentrating the waste of sea pens in the fjords through which wild salmon swim to their natal streams to the fact that salmon farming causes a net reduction of protein reaped from the ocean, the results don’t look good. Recent victories, such as the banning of net-pen fish farms in the waters of Washington State, are an indication that we are awakening to the environmental price of engineered fish. It is said that we will continue to make the same mistakes unless we understand them. The New Fish combines nature writing from Norwegian fjords, the coast of Canada, Icelandic landscapes and the far south of Chile with character-driven literary non-fiction and classic muckraking. The authors started with this question: What happens when you create a new animal and place it in the sea? This book will tell you the answer. Trade Review"The detailed history of salmon fisheries is a bit niche, but the authors succeed in highlighting how small decisions can have big ecological consequences." -- Publishers WeeklyJournalists Saetre and Østli make their English language debut with this eye-opening overview of the damage salmon fisheries inflict on the environment and public health. Chronicling the industry’s early days in the authors’ native Norway, they describe how in 1970 brothers Sivert and Ove Grøntvedt established the first salmon farm after putting a large net filled with 16,000 young fish in the sea, and how in 1971 researcher Trygve Gjedrem started a breeding program that still provides much of the world with its salmon stock. According to the authors, the work required to sustain salmon farms had far-reaching if unintended consequences. The tight quarters led to the proliferation of salmon lice that threatened wild populations when captive fish escaped, but delousing agents proved deadly to marine life near the farms. Humans were affected, too: Farmed salmon have gray meat unless they’re fed a synthetic compound that, when consumed in large quantities, can cause vision problems in people. The detailed history of salmon fisheries is a bit niche, but the authors succeed in highlighting how small decisions can have big ecological consequences. It’s a smart if somewhat narrow appraisal of humanity’s complicated relationship with nature. Photos.

Book SynopsisNothing stays buried foreverLifeboat volunteer DI Shona Oliver receives a Mayday call coming from Kilcatrin Island. Upon the beach is the badly burned body of a man, and a boy lies gravely injured nearby. Strewn around them are scores of Second World War incendiary bombs, presumably washed up by the tide from Beaufort’s Dyke, an offshore arms dump deep in the Irish Sea.The dead man is a local fisherman – his son the other victim – and it rocks the tight-knit community on the shores of the Solway Firth. As lead detective, Shona has to maintain a professional distance. But she can’t ignore the hardship that her neighbours who make a living at sea are experiencing. Anger is directed at the Ministry of Defence when the fallout threatens tourism, and livelihoods including Shona’s own family B&B business are at risk. Suspicious behaviour seems to be found at every turn. It’s impossible for Shona to get to the truth unless she can gain the trust of those who know more than they’ve been willing to reveal.

Book SynopsisAquaculture exemplifies the ongoing global struggle to strike a sustainable balance between the conflicting needs of a rapidly increasing world population, human health, ecosystem health, the welfare of wild and domesticated animals, and the economic principles of globalized economies. On the one hand, aquaculture has great potential for providing us with a healthy and nutritious food supply whilst alleviating pressure on captive fisheries and reducing fisheries-induced habitat destruction, overfishing, genetic modification of wild populations, and wholesale waste of bycatch. On the other hand, aquaculture relies heavily on clean water, an increasingly precious (and dwindling) resource that is subject to intense pressure of being used for many competing objectives. This concise primer introduces students to the basic concepts, opportunities, and challenges of aquaculture with an emphasis on ecological considerations. It provides a critical assessment of current aquaculture practices frTrade ReviewThis important new volume on aquaculture presents a remarkable synthesis of all the key issues involved in the commercial culturing of freshwater and marine species. It provides a comprehensive overview of the basic biological elements of aquaculture, including new information on the use of genomic and genetic tools, and incorporates these analyses into a broader ecological, environmental, and sociological context. The emphasis on strategies for protecting water quality-a vital part of the aquaculture enterprise-is especially well-presented. The volume deserves wide readership among students and scientists who not only have interests in aquaculture, but also in sustaining robust aquatic ecosystems in freshwater and marine environments. * George N. Somero, David and Lucile Packard Emeritus Professor of Marine Science, Hopkins Marine Station, Stanford University, USA *Readers can obtain an excellent overall summation of the problems and ways forward as people rely more and more on augmented fish and seafood production.

Book SynopsisIn Catching Hell, longtime seafood mogul Allen Ricca and author Joe Muto take readers behind the scenes of the high-end restaurant world and the international market for seafood, and how that industry has been impacted perhaps like no other due to the COVID-19 pandemic.This book exposes the fact that the American diner is being lied to on a regular basis. The culprit varies – sometimes it’s a chef or restaurant owner trying to cut corners to save money; other times it’s an unscrupulous supplier looking to pass off poor product to an unwitting receiver. And the cost of that scam eventually gets passed on to the consumer, whether it be in the form of higher prices at restaurants and markets, lower quality (or even counterfeit) product getting delivered onto your plate, or – God forbid – food poisoning. Furthermore, Ricca argues, the pandemic has only increased corruption in this industry.This book serves as both an exposé and a call to arms, empowering consumers with the knowledge to make more informed choices when dining out. Some of the things this explosive book reveals: The one fish you should never order, one that’s always a rip-off. (And the one fish that’s always a delicious, virtually-unknown bargain.) Why restaurants that advertise “fresh” fish are almost always lying. How to get your favorite restaurant to treat you like royalty – without dropping thousands of dollars. How the covid-19 pandemic has impacted our food supply chain and what it has meant for the everyday worker. Trade Review"An essential read for anyone looking to understand how the restaurant industry really works. Informative, hilarious and gripping. You'll devour every page and still be left wanting more."—Chef Hung Huynh, Season 3 Winner of Bravo’s Top Chef"A book that will not disappoint! Catching Hell is both entertaining and informative, a must read for 2022."—Jamie Bissonnette, James Beard award-winner, Chef & Partner Toro, Coppa, and Little Donkey Boston"Ricca knows this industry inside and out. He tells the story of his colorful career, and explains the business, with enthusiasm, wit, and candor—in lively, often salty, language we all can understand."—Robert Hormats, former vice chairman Goldman Sachs International and Under Secretary of State for Economic Growth, Energy, and the environment (2009-2013)"Come for the seafood, but stay for the gripping tale of personality clashes behind the scenes at some of your favorite restaurants. Ricca and Muto paint a vivid picture of a rough-and-tumble industry that touches all of our lives, but until today, most of us knew nothing about."—Patrick O’Shaughnessy CEO Positive Sum Venture Capital and author, Millennial Money: How Young Investors Can Build a Fortune"Allen Ricca is constantly exploring new products and discovering new tastes, as well as revisiting & satisfying old ones. One thing is constant: his curiosity and dedication to quality food (sourcing) as well as his unyielding commitment to our industry's supply chain is unmatched. I am proud to work with him."—Erik Sun, Owner, PursuitFarms Wagyu, executive chef Intercrew LA"I have known and worked with Allen and his family for over 25 years. This endlessly entertaining book perfectly captures his personality, and gives an unflinching look at the chaotic process that brings seafood from oceans around the world to restaurant kitchens around the corner."—M.J. Alam, Partner and Executive Chef Limani Rockefeller Center NYC"Everyone has something to learn from Catching Hell—whether you are interested in seafood traceability, ethical business practices, or just getting the most out of your seafood order. "—Morgan Chow scientist for California Natural Resources Agency"A heady rollercoaster of jaw-droppers and heart-warmers, Catching Hell is an honest-to-goodness gift to the everyday diner and food-lover.

Book SynopsisThe first deep-sea fishing boats of Cornwall are regarded as being influenced by the three-masted French luggers that sailed over to cause havoc amongst the locals. However, fishing had been practised by Cornishmen for many generations before that, with mackerel and pilchard fishing being prominent. Inshore, lobster and crab fishing had also been popular for generations. This book looks at the development of Cornish fishing boats, from the lugger to Pilchard seine-net boats, once as prolific as the luggers and usually built locally, as were traditional lobster and crab vessels. These are discussed alongside more unusual boats, such as the St Ives ''jumbo'' and the Mevagissey ''tosher''. The book brings the story up to date, including modern photos of existing boats gathering for the bi-annual Looe lugger regatta. After motorisation, the shape of the boat changed forever and the adaptation of old boats to accommodate engines is examined, as are the famous yards and boatbuilders of Cornwall still operational today.

Book SynopsisPacific salmon are among the dominant fish groups and the main consumers of forage resources in the upper layer of the subarctic Pacific. In the last years, the majority of Pacific salmon species in North America and in Asia have experienced an increase in abundance, and their role in marine ecosystem has changed. This book examines the feeding habits and trophic status of the Pacific salmon in different regions of the subarctic Pacific under the influence of changing environmental factors. Moreover, this book deals with the present-day Norwegian regulations of saltwater salmon fisheries and particularly Norway''s attempts to harmonise the interests of people and fish. Polycyclic aromatic hydrocarbons (PAH) constitute carcinogenic environmental contaminants such as dioxins. Fishes and particularly Salmonids are very sensitive to the PAH toxicity. The natural and anthropogenic PAH generations lead to an environmental contamination of water, sediments and feed of Salmonids, then to a fish contamination and finally to a human food contamination eating those contaminated fishes. The authors of this book discuss the monitoring of these chemical contaminants in salmon, essential to evaluate the pollution related to human activities and to guarantee the quality of fish as food for human consumption. In addition, the effects of replacing fish oil (FO) with rapeseed oil (RO) in Atlantic salmon post-smolt diets is discussed, and its subsequent effects on liver and muscle fatty acid (FA) composition and growth are described. This book also describes the high-pressure processing of fresh salmon and light preserved products like cold smoked salmon. Its effect on microorganisms, enzymes and organoleptic properties are analysed, as well as the process parameters, pressure, duration, and temperature affecting microorganisms, structure and colour, which all determine the market chances of the product. Moreover, the authors underline the influence of three main factors -- super-chilling, dietary lipids and pre-slaughter crowding stress, on Atlantic salmon flesh quality, with a focus on the role of lysosomes and lysosomal enzymes, cathepsins B and L, in muscle structure degradation and flesh quality.

Book SynopsisThe National Oceanic and Atmospheric Administration (NOAA) has conducted an assessment in response to national and international concerns that overcapacity, overfishing and other often co-occurring undesirable outcomes of a common management problem prevent the attainment of the goal of productive and sustainable marine ecosystems. Other undesirable outcomes include high levels of bycatch, adverse impacts on habitat, less safe working conditions on fishing vessels, lower product quality, poor economic performance, less viable fishing communities, non-compliance with regulations and a management regime that is unnecessarily complex, contentious and costly. This book identifies and describes U.S. federally managed fisheries with the most severe examples of excess harvesting capacity, and recommends cost-effective and privately funded measures that could be used to reduce excess harvesting capacity.

Book SynopsisSex determination, differentiation and gamete maturation are well organised molecular events in vertebrates. In vertebrates, sex determination and differentiation are two important events in the development of gonads (testis or ovary). Sex determination is the genetic (sex chromosomes) or environmental process by which the sex (male or female) of an individual is established. During embryonic development, primordial germ cells migrate from the site of origin to the gonadal primordia where they differentiate along with somatic cells and finally form the indifferent/bipotential gonads. Depending on the action of various factors the bipotential gonads give rise to either testis or ovaries. In most vertebrates, excluding fishes and some amphibians, the event of sex determination is controlled genetically and later the progression of gonadal development is controlled by hormones and other factors. Interestingly, these processes in fishes are controlled not only genetically but also through hormones or environmental factors. These characteristics make fish the champions of sex reversal and serve as excellent animal models to precisely understand sexual development. The next interesting aspect is meiotic maturation which is essentially mediated by gonadotropins and progesterone metabolites to trigger final gamete maturation in fishes which is different from mammals. The novel aspects pertaining to gamete maturation has been studied in great detail in fish which depicts precise regulatory events of gamete maturation.

Book SynopsisThis informative new volume on the reproduction and development of zebrafish provides a timely and fundamental set of chapters presenting new data and critical reviews to the novice student and veteran researcher alike. It covers two major areas of zebrafish biology, reproduction and development, with toxicology emphasised in a number of chapters. Historically, reproductive biology of zebrafish has not been given the attention afforded to the more intensively studied aspects of embryonic development in this model species. In part, this may be due to fewer tools available to zebrafish reproductive biologists. However, with the advent of transparent juvenile and adult lines, new areas of reproduction research become visible both figuratively and literally. Two chapters are devoted to presenting these exciting new fish lines and examples of their use in research to the reproductive biology research community. Reproduction and embryonic development are a continuum which is emphasised in a new review on RNA-binding proteins in the zebrafish oocyte. It is increasingly clear that embryonic development is dependent upon factors present in the female gamete known collectively as "maternal effects", and these oocyte components are beautifully summarised in this chapter. Other chapters cover normal spawning periodicity and vitellogenic oocyte growth dynamics that should interest ovarian physiologists and those interested in zebrafish husbandry.

Book SynopsisCatch share programs are a fishery management tool that dedicates a secure share of quota allowing individual fishermen, fishing cooperatives, fishing communities, or other entities to harvest a fixed amount of fish. With clearly defined fishing privileges, fishermen no longer need to "race to fish," but instead can make harvest decisions based upon market conditions, improving economic performance, and weather conditions, which improves crew safety. These incentives can reduce the cost of taking conservation actions and can encourage individual fishing choices that are more consistent with sustainable fishing practices such as reducing low-value or undersized catch that is discarded at sea but is frequently associated with high mortality rates. The ability to align fishermen''s economic incentives with the long-term biological health of the fishery singularly distinguishes catch share programs from traditional fishery management strategies (i.e., trip limits, gear restrictions, etc.). Nationwide, there are 15 catch share programs currently in operation. This book provides basic information on the economic performance of U.S. catch share programs using a standard set of indicators that are uniformly applied across these highly diverse programs.

Book SynopsisAquaculture is one of the fastest growing sectors of agriculture globally. Production in freshwater and marine fisheries has plateaued or is declining, and the increasing demand for seafood and need for affordable protein sources in third world countries will ensure growth of aquaculture in the future. Tilapia are the second most cultured fish world-wide behind the carps, and even though they are easily cultured in a wide variety of environments and are relatively resistant to aquaculture stressors compared to other cultured finfish species, significant losses to disease still occur under intensive culture. This book discusses the biology, management practices and human consumption of tilapia.

Book SynopsisIn general, aquaculture and fish farming cause negative impacts on the environment and wild fish populations. One of the major problems is the escape of farmed fish, especially exotic species, which can alter the population dynamics and ecology of wild stocks. Therefore, the reduction or even extinction of natural stocks may occur through predation and/or competition for resources. This book discusses the biology, behaviour and conservation strategies of both carp and catfish.

Book SynopsisThe fishery defines the culture and heritage of Newfoundland and Labrador. But historically, it was merchants who wielded power and reaped the bounty created by workers. This changed in 1971 when a group of dedicated people created what was then known simply as the Fishermens Union. Their goalwhich was derided as idealistic and doomed to failure -- was to change the power structure of the fishing industry to ensure workers could finally obtain their rightful share of the wealth. But the naysayers were wrong, and the union has survived market crashes, industry restructuring, divisive corporate campaigns, scandalous levels of foreign overfishing, and devastating fish stock collapses. Earle McCurdy, who spent most of his career with the FFAW-Uniform, has been at the center for many of the unions important battles. Drawing on personal experience, as well as dozens of interviews and extensive research, McCurdy tells the compelling true story of challenge and triumph.

Book SynopsisNorwegian spring-spawning herring and Northeast Arctic cod are two of the largest and commercially most important fish stocks in the North Atlantic. Both these stocks have their spawning fields at the Norwegian coast and they have been the major target species for Norwegian fisheries for a millennium. They are also among the few fish stocks in the world which have been systematically investigated and monitored for more than a century. The scientific results arrived at early in the century for these two stocks, formed the basis for much of the development in international fisheries science later on. This book describes how fisheries, fisheries science and management for Norwegian spring-spawning herring and Northeast Arctic cod developed during the 20th century. Both populations had serious declines in stock size and yield due to overfishing. The herring stock was in a state of collapse for about 20 years. Management measures introduced during the two-three last decades made both stocks recover in the 1990s.

Book SynopsisThis volume presents the results of an interview survey among Greenland subsistence hunters on walruses and the catch of walruses in West and Northwest Greenland. In these areas, the catch of walruses is still an important part of the traditional subsistence hunting culture. The Greenland walrus hunting grounds have experienced marked environmental changes due to climate change and quotas were introduced for the catch across all of Greenland in 2006. Thus, we wanted to explore how these changes had affected the local communities by interviewing seventy-six experienced walrus hunters living in twenty-two settlements and towns along the ca. 1,700 km coast from Maniitsoq in the south to Siorapaluk in the north. The interviews resulted in a wealth of detailed information about how climate changes and introduction of quotas have affected the walruses and the walrus hunting practice. The main text summarises the broad findings while more details are provided in the individual hunter statements in four appendices.

Book SynopsisThe karst landforms of China are renowned around the world for the beauty of their landscapes, but it is less well appreciated that they also contain extensive cave systems with very significant underwater habitats. China also has an extremely high level of biodiversity, including over 1,500 freshwater fish species. Unsurprisingly, some of these species inhabit the karst cave systems and have flourished and diversified under unique environmental conditions. As a result, cave fishes in China are particularly abundant and diverse when compared to those of other countries of the world. These remarkable fishes have received considerable research attention from Chinese ichthyologists and, for the first time, this book makes their resulting findings directly accessible to the English-speaking world through a remarkable endeavour of Sino-British collaboration.

Book SynopsisThe history of pearling is inextricably linked to the history of Bahrain, the strategically-located Gulf archipelago set amidst one of the richest and most plentiful pearl fisheries in the world. Sea of Pearls tells the story of pearl fishing in the Gulf, and the role that this timeless industry played in global commerce, fashion, urban development, political struggles and the earliest ever long-distance maritime trade. From the 18th to 20th centuries, the industry boomed, as pearls were fished by ever-increasing numbers of tribesmen and townspeople to feed an expanding international market. Bahrain was at the centre of this activity before the industry's collapse in the early 20th century with the introduction of cultured pearls from Japan. The influx of traders, migrants, merchants and political advisors - each seeking to partake in the booming trade - left an indelible mark on the Gulf, germinating new city-states with cosmopolitan communities, which are now the global metropolises that we know today. Launching with the generous support of the Bahrain Authority of Culture and Antiquities (BACA), Sea of Pearls spotlights Bahrain's UNESCO-listed 'Pearling Path', a 3.5 km pathway taking visitors on a journey from the oyster beds of Muharraq to the historical merchant homes and other structures involved in the pearling economy. Lavishly illustrated, this book covers in unprecedented detail the history, development, impact and florescence of this ancient industry before it died out and was eclipsed in the age of oil. It is essential reading, not only for those wishing to understand the historical growth and geopolitical dynamics of pearl fishing, but also for those interested in the history and origins of the Gulf states. It is the fascinating, seldom-told story behind the world's enduring desire for one of humankind's most prized precious stones.

Book SynopsisLiving resources of the sea and fresh water have long been an important source of food and economic activity. With fish stocks continuing to be over-exploited, there is a clear focus on fisheries management, to which acoustic methods can and do make an important contribution.Trade Review"This very useful guide is now in its second considerably improved and updated edition … highly recommended." (Work Boat World, October 2008) "The new volume of Fisheries Acoustics captures the advances in the technology associated with the use of acoustics to find, classify, size, enumerate, examine the behaviour of, and help manage various types of fish."(Reviews in Fisheries Science, November 2006) "A thorough treatment of the acoustic instruments, sophisticated displays, and microprocessor-based signal processing used throughout the world to map the distribution of fish, estimate biomass, locate fish shoals, monitor fish movement, and study fish behavior. Emphasizes the practical methods for assessing fish stock; also discusses the design, execution, and interpretation of surveys, drawing from examples in many parts of the world."(Book News (SciTech Book News), September 2005) "If you really want to know how depth sounders, sonars and their ilk work, you need this book. If you want to learn how to use your fish finding equipment more effectively, you need it even more."(Ausmarine) "This textbook is an essential reference for professionals involved with the design and use of acoustic equipment for assessing fisheries and plankton populations...this book will be an invaluable tool for any practitioner or researcher requiring an understanding of the fundamentals of fisheries acoustics.the modernised edition is timely and welcome"(Reviews in Fish Biology and Fisheries (2007), 17:633-634)Table of ContentsSeries Foreword.

Book SynopsisThe impact of pollution on fisheries and the potential health implications of eating contaminated fish are areas of considerable concern for the fishing and aquaculture communities, government bodies and the general public. Pollution, as well as over fishing, may well be contributory to recent serious declines in global fish stocks.Trade Review"This book will be an important resource for environmental toxicologists and fishery biologists. Postgraduates and researchers new to the field will also find the book invaluable. For others, working within narrow specialist fields, it provides an insight into the wider impacts that pollution in fish can cause."

Book SynopsisBeginning late in the nineteenth century and culminating in the 1985 Pacific Salmon Treaty, Canada and the United States carried out long and contentious negotiations to provide a framework for cooperation for conserving and sharing the vitally important Pacific salmon resource. This book traces provides an insider's perspective on the tumultuous negotiations.Trade Review"Both authors have been deeply immersed in Canada's management of its salmon resources and conflicts with US fisheries. The treatment of the subject is nicely balanced and even-handed... This masterful account is likely to be the definitive work, given its combination of breadth and depth with the added value of a balanced insider's view." - Edward L.
