Download or read book The Future of Bluefin Tunas written by Barbara A. Block and published by JHU Press. This book was released on 2019-08-06 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most thorough and current account of scientific research on bluefin tunas—the largest, most sought-after tunas in the world Bluefin tunas are dominant keystone predators known for their impressive size, strength, endurance, and speed. Electronic tags have revealed that they can dive to great depths (over 6000 feet) and migrate vast distances—from frigid subpolar seas to warm tropical waters—for spawning. Prized for their rich taste and unique texture, bluefin tunas are also a worldwide commodity of great value. However, over the past few decades, overfishing throughout their range has led to significant population reductions. In The Future of Bluefin Tunas, Barbara A. Block brings together renowned bluefin experts from 15 different countries to share the latest information on the science, fisheries policy, and management decisions related to each of the three species within the Thunnus group—Atlantic, Pacific, and Southern. Synthesizing basic and applied research, the book delves into every aspect of these majestic fish, from their life history and genetic makeup to their ecology and migrations. Ichthyologists and marine scientists dedicated to the study of these fishes report on the latest stock assessments, explore the results of advances such as biologging and DNA sampling, and assess the potential of bluefin tuna aquaculture. The Future of Bluefin Tunas provides critical research findings to inform decisions that will impact tunas and the ocean ecosystems they affect. Scientists, fisheries managers, policymakers, and marine conservationists will take away key data from this timely volume to help them ensure these remarkable fish continue in perpetuity.

Book excerpt: Historically, whenever tuna was hauled ashore, the sounds of battle were never far away. ‘Tuna Wars’ tells the untold story of the power struggles emerging around tuna, from the distant past to your present-day dinner table. In the ancient past, the giant tuna was the first fish to become the basis of a large-scale industry and a ‘global’ trade that created fortunes: Hannibal was able to finance his elephant campaign on Rome thanks to tuna. From the Middle Ages on, a tuna fishing monopoly on Spain’s southern coast allowed the nobility to completely dominate the area and even lead the ‘invincible’ Armada. When the markets for tuna increased exponentially thanks to technical advances, tuna eventually became a billion-dollar business and one of the most-consumed fish species worldwide. But this massive expansion came at a price. An 18th century monk in Madrid was the first to warn that tuna fisheries needed to be run sustainably for the sake of future generations. And the issue of sustainability would go on to become a game-changer in the modern tuna wars, characterized by new alliances and partnerships, hybrid warfare and commercial power struggles. In addition to accompanying you through the history of tuna and sharing insights into fisheries science and approaches to sustainably managing fisheries, Tuna Wars offers practical guidance on choosing sustainably fished tuna. In short, it will tell you everything you ever wanted to know about tuna, but were afraid to ask.
Download or read book Four Fish written by Paul Greenberg and published by Penguin. This book was released on 2010-07-15 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: “A necessary book for anyone truly interested in what we take from the sea to eat, and how, and why.” —Sam Sifton, The New York Times Book Review Acclaimed author of American Catch and The Omega Princple and life-long fisherman, Paul Greenberg takes us on a journey, examining the four fish that dominate our menus: salmon, sea bass, cod, and tuna. Investigating the forces that get fish to our dinner tables, Greenberg reveals our damaged relationship with the ocean and its inhabitants. Just three decades ago, nearly everything we ate from the sea was wild. Today, rampant overfishing and an unprecedented biotech revolution have brought us to a point where wild and farmed fish occupy equal parts of a complex marketplace. Four Fish offers a way for us to move toward a future in which healthy and sustainable seafood is the rule rather than the exception.
Download or read book The Bluefin Tuna Fishery in the Bay of Biscay written by José Luis Cort and published by Springer. This book was released on 2019-02-07 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book is an original contribution to the knowledge on fishing and research associated with one of the most enigmatic fish of our seas: bluefin tuna, Thunnus thynnus (L.). Based on available evidence, it reconstructs the possible methods used to catch large spawners in the Strait of Gibraltar thousands of years ago and describes the much more recent overfishing that led to a great reduction in the catches of the trap fishery on the area and the disappearance of the northern European fisheries. It is the first book to relate the overfishing of juvenile fishes in certain areas to the decline of large spawners in other very distant areas, revealing one of the main underlying causes of this decline, which has remained a mystery to the fishing sector and scientists alike for over 50 years. This finding should serve to prevent similar cases from arising in the future.
Download or read book The Physiological Ecology of Tunas written by Gary Sharp and published by Elsevier. This book was released on 2012-12-02 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Physiological Ecology of Tunas documents the proceedings of the Tuna Physiology Workshop held at the National Marine Fisheries Service Southwest Fisheries Center at La JoDa, California, January 10-15, 1977. The contributions made by researchers at the workshop are organized into seven chapters. The first chapter includes studies on the morphological diversity and muscle-tissue-specific enzymatic attributes of scombrids. Papers in the second chapter deal with the integrated aspects of tuna behavior and capabilities that result from their complex cardiovascular system. The third chapter contains studies on skipjack tuna white muscle and the locomotor muscles of Scomber and Katsuwonus. The fourth chapter focuses on the thermal biology of tunas while the fifth chapter examines the hydromechanics of tuna propulsion. The sixth chapter provides information on energetic costs of tunas, and observations on physiological demands and correlates. It culminates with a conceptual model for the complex life cycle of the extant "ultimate tuna," the Atlantic bluefin tuna. The seventh chapter discusses applications of tuna physiology studies.

Download or read book Dolphins and the Tuna Industry written by National Research Council and published by National Academies Press. This book was released on 1992-02-01 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents key conclusions about the controversial killing of thousands of dolphins each year during tuna fishing in the eastern tropical Pacific. Dolphins drown in nets that are set to catch yellowfin tuna, which tend to swim beneath dolphin herds. After 20 years of intense debate among environmentalists, the tuna industry, and policymakers, this fatal by-product of tuna fishing remains a high-profile public issue. Dolphins and the Tuna Industry provides a neutral examination of the scientific and technical questions at the core of the problem. Recommendations for solutions are offered in two areas: developing new techniques that promise to reduce dolphin mortality with the existing purse-seine method of tuna fishing, and developing entirely new methods of finding tuna that are not swimming with dolphins. Dolphins and the Tuna Industry provides a comprehensive, highly readable overview of the dolphin-tuna controversy, useful to experts and newcomers to the issue. It explores the processes of tuna fishing and dolphin mortality, the status of the tuna industry, and the significant progress made in reducing dolphin mortality through modifications in fishing practice. The volume includes: An overview of U.S. laws and policies relating to tuna and dolphins. An illustrated look at how tuna fishing crews use their equipment, focusing on the purse seine, which is the method most economical to the industry but most deadly to the dolphins. An overview of what is known about tuna and dolphin populations and the remarkable bond between them. A step-by-step description of the fishing process and efforts to let dolphins escape from the nets. An analysis of possible approaches to reducing dolphin kill, including more stringent regulatory approaches and incentives for the tuna industry. This book will be indispensible to environmental and animal protection groups, tuna fishing crews and processors, companies that market tuna products, policymakers, regulators, and concerned individuals.
