The crash of 19 stocks of Fraser River sockeye over a 15 year period forced the Canadian government to close all fishing from 2007 to 2009. The Canadian government, desperate for answers, or at least looking for a way to deflect criticism, struck an inquiry led by justice Bruce Cohen that would last over a year. The decline was quick and dramatic. It looked like Fraser river sockeye populations were going extinct. For more than 20 years, Alexandra Morton, an independent biologist, has been a vocal campaigner against open net pen fish farms. Her research and subsequent publications outline a case that sea lice and disease from the farms have spread to wild salmon populations. She argues that open net fish farms is the source of the problem. But instead of embracing her findings, government and industry have vilified the whistleblower and tried many things to silence her. Finally, after nearly a year of hearings, Morton appeared at the inquiry for two days. The battle lines were quickly drawn and the inquiry became more like a trial of a witness than an information gathering process. It is rare that partnerships between government and corporate interests are acknowledged in public. It's even more rare to see it in action.Includes an extensive bibliography along with over 50 photos in colour and black and white.

"If you've been out there, read this book. If you haven't been out there, never mind watching "reality television" shows - you should read this book, as well. David Goethel is the real thing: a one-of-a-kind mix of grit, guts, determination, passion for his livelihood, and respect for the resource. His story has as much to do with the future of commercial fishing as it does its past."--Brian Robbins, senior contributing editor, Commercial Fisheries News"New England fisheries have a rich history but are faced with several challenges that jeopardize their sustainability. Fortunately, we have fishermen like David Goethel, who dedicated his life to fishing, collaborative research, and stakeholder-driven management and give us hope for creative solutions. I can't think of a person who taught me more about the marine ecosystem, fish biology, fisheries, and effective policies than David. I expect this book will give us the insights we need to sustain the fisheries he loves."--Steve Cadrin, PhD, University of Massachusetts""David's book makes you feel like you are personally on the crew of his fishing boat the Ellen Diane. As a reporter, when I had a question about fishing, he was the credible source."--Roger Wood, associate publisher and podcast producer, InDepthNH"As a ground fish "non permit holder" I learned a lot from David about dealing with the complexity of Federal fairness while watching him work so hard to survive from the North Atlantic fishery. Yet, David Goethel most importantly showed me by example how one deals with impossible road blocks in commercial fishing and personal life. Read Dave Goethel's Endangered Species. It's tough to put down."--John Bell, Mayor of the City of Gloucester, MA, 2002-2008, chair and a founder of The Northeast Seafood Coalition"Dave Goethel's book tells a compelling story of his lifelong love of the ocean and passion for fishing. The book chronicles many fascinating stories of the joys and perils of his journey which starts as a young boy with his father on deep sea fishing boats and moves to being a captain of those same boats while getting a college degree in biology before becoming a commercial fisherman and eventually a fisheries manager. The author also provides a thought-provoking picture of fisheries management and commercial fishing in New England and offers potential solutions for conserving both the fish resources and the small boat commercial fishermen who provide fresh fish for our tables."--Doug Grout, retired fisheries manager and fisheries biologist

Biotechnology refers to a field of applied science that creates products and processes from living organisms and their derivatives. It entails the understanding of the functioning of living organisms at the molecular level. It draws from several academic fields such as chemistry, biology, physics, and mathematics. Marine biotechnology is the use of bioinformatics, biotechnology, and molecular and cell biology to produce products and processes from marine organisms. It is concerned with ocean exploration for creating novel chemical products, enzymes, medicines, and other products and processes. It also contributes significantly to biomaterials, seafood and aquaculture safety, health care diagnostics, and bioremediation. This book unravels the recent studies in the field of marine biotechnology. It will also provide interesting topics for research, which interested readers can take up. This book is a vital tool for all researching or studying marine biotechnology as it gives incredible insights into the emerging trends and concepts.

Certain enzymes that are secreted by microbes such as fungi and bacteria present in the marine environment are called marine enzymes. These microbes secrete different enzymes based on their ecological functions and habitat. Marine microorganisms and their enzymes can function in environments with high pressure and light, high salt concentrations, and in a wide variety of temperatures. Marine enzymes are a significant source of biocatalysis. Fermentation process can be used to produce and extract marine enzymes from animals, microorganisms, and plants. Enzymes generated by marine microorganisms are used in a variety of sectors, including textiles, chemical, pharmaceuticals, biomedicine, agriculture, and food processing. Marine enzymes exhibit a wide range of pharmacological uses, and can be used as pesticides, mycotoxins, pigments, antiparasitics, antibiotics, herbicides, antitumor agents, toxins, and growth promoters for both plants and animals. This book is a compilation of chapters that discuss the most vital concepts and emerging trends with respect to the sources, biocatalytic characteristics, and bioprocesses of marine enzymes. It will help the readers in keeping pace with the rapid changes in this area of study.

Marine biotechnology refers to the use of biotechnology tools on marine resources. It utilizes resources from aquatic living organisms to create new commercially viable applications or products. Marine biotechnology has demonstrated its potential in a wide range of applications from biomedicine to the environment. Commercial applications of marine biotechnology include enhancing the production of marine organisms, bio-prospecting, creation of new products, as well as developing biosensors and diagnostics. The goal of current marine biotechnology research is to develop new methods and tools that will improve the economically and environmentally viable industrial production of compounds derived from marine sources. This book unfolds the current research in marine biotechnology, which will be crucial for the progress of this field in the future. Most of the topics introduced herein cover new techniques and the applications of this area of biotechnology. The book aims to serve as a resource guide for students and experts alike and contribute to the growth of the discipline.
