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.
Download or read book Guidelines for the Routine Collection of Capture Fishery Data written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 1999 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: "These guidelines aim to help those who design routine data collection programmes, focusing on the relationship between typical questions asked by policy-makers and managers, and the data required for providing reliable answers. Fisheries policy and management objectives, particularly under the precautionary approach, need to be based upon analyses of reliable data. Data are needed to make rational decisions, evaluate the fisheries performance in relation to management activities and fulfil regional requirements. These objectives are achieved using fishery performance indicators. Indicators are used to measure the state of the resource, the performance of fishing controls, economic efficiency, socio-economic performance and social continuity. The primary factor in choosing what data to collect is the link between the necessary operational, biological, economic and socio-cultural indicators and their associated variables. The way in which different data variables are collected needs tobe tailored to the structure of the fishery. The strategy will be strongly influenced by the budget and personnel available, and the degree to which fishers and others co-operate. The programme must identify which variables should be collected through complete enumeration and which can be sampled. Collection methods are influenced by the variable itself, the strategy, collection point and the skill of the enumerator. Once collected, fishery data must be stored securely, but made easily available for analysis, which is achieved through a computer-based data management system, following the basic data processing principles. The implementation of a data collection programme should follow a normal project cycle, developing a new legal and institutional framework as appropriate"--Abstract.

Download or read book Historical Trends of Tuna Catches in the World written by Makoto Miyake and published by Food & Agriculture Org.. This book was released on 2004 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The total world catch of the major commercial tuna species (albacore, bigeye, bluefin, skipjack and yellowfin) has increased during the last 50 years (from 0.4 to 3.9 million tonnes), but the pattern of increase has varied among species, oceans and fishing gears. The Pacific Ocean has been the predominant region in the world catch, with catches from the Indian Ocean having exceeded those from the Atlantic Ocean in recent years. This publication examines historical trends in the catches of these tuna species and considers the causes of the variations.

Download or read book Mechanisms of Migration in Fishes written by James D. McCleave and published by Springer Science & Business Media. This book was released on 2013-03-13 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last major synthesis of our knowledge of fish migration and the underlying transport and guidance phenomena, both physical and biological, was "Fish Migration" published 16 years ago by F.R. Harden Jones (1968). That synthesis was based largely upon what could be gleaned by classical fishery-biology techni.ques, such as tagging and recapture studies, commercial fishing statistics, and netting and trapping studies. Despite the fact that Harden Jones also provided, with a good deal of thought and speculation, a theoretical basis for studying the various aspects of fish migration and migratory orientation, progress in this field has been, with a few excepti.ons, piecemeal and more disjointed than might have been expected. Thus we welcomed the approach from the NATO Marine Sciences Programme Panel and the encouragement from F.R. Harden Jones to develop a proprosal for, and ultimately to organize, a NATO Advanced Research Institute (ARI) on mechanisms of fish migration. Substantial progress had been made with descriptive, analytical and predictive approaches to fish migration since the appearance of "Fish ~ligration." Both because of the progress and the often conflicting results of research, we felt that the time was again right and the effort justified to synthesize and to critically assess our knowledge. Our ultimate aim was to identify the gains and shortcomings and to develop testable hypotheses for the next decade or two.

Download or read book Regional Fisheries Oceanography of the California Current System written by Sam McClatchie and published by Springer Science & Business Media. This book was released on 2013-09-30 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: The California Current System is one of the best studied ocean regions of the world, and the level of oceanographic information available is perhaps only surpassed by the northeast and northwest Atlantic. The current literature (later than 1993) offers no comprehensive, integrated review of the regional fisheries oceanography of the California Current System. This volume summarizes information of more than 60-year California Cooperative Oceanic Fisheries Investigation (CalCOFI). While providing a large bibliography, the intent was to extract themes relevant to current research rather than to prepare a compendious review of the literature. The work presents a useful review and reference point for multidisciplinary fisheries scientists and biological oceanographers new to working in the California Current System, and to specialists wishing to access information outside their core areas of expertise. In addition it aims to deliver an up to date reference to the current state of knowledge of fisheries oceanography in the California Current System.

Download or read book The Red Circle written by Brandon Webb and published by St. Martin's Press. This book was released on 2012-04-10 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explosive, revealing, and intelligent, The Red Circle provides a uniquely personal glimpse into one of the most challenging and secretive military training courses in the world. Now including an excerpt from The Killing School: Inside the World's Deadliest Sniper Program BEFORE HE COULD FORGE A BAND OF ELITE WARRIORS... HE HAD TO BECOME ONE HIMSELF. Brandon Webb's experiences in the world's most elite sniper corps are the stuff of legend. From his grueling years of training in Naval Special Operations to his combat tours in the Persian Gulf and Afghanistan, The Red Circle provides a rare and riveting look at the inner workings of the U.S. military through the eyes of a covert operations specialist. Yet it is Webb's distinguished second career as a lead instructor for the shadowy "sniper cell" and Course Manager of the Navy SEAL Sniper Program that trained some of America's finest and deadliest warriors-including Marcus Luttrell and Chris Kyle-that makes his story so compelling. Luttrell credits Webb's training with his own survival during the ill-fated 2005 Operation Redwing in Afghanistan. Kyle went on to become the U.S. military's top marksman, with more than 150 confirmed kills. From a candid chronicle of his student days, going through the sniper course himself, to his hair-raising close calls with Taliban and al Qaeda forces in the northern Afghanistan wilderness, to his vivid account of designing new sniper standards and training some of the most accomplished snipers of the twenty-first century, Webb provides a rare look at the making of the Special Operations warriors who are at the forefront of today's military.
