In the Western Central Atlantic Fishery Commission (WECAFC) area, large pelagics contribute only about 6% of total landings, but are nonetheless significant for many countries. Large pelagic fishes are caught in all WECAFC states, and within the WECAFC region by several distant water fishing nations. However only 19 of 40 WECAFC Member States report catches to FAO. The fisheries range in scale and technological sophistication from artisanal fishers trolling from canoes to modern commercial longliners and purse seiners (mostly from distant water fishing nations). The available information on development of small-scale and large scale fleets targeting large pelagics, indicates a significant trend of increasing fishing capacity in the countries of the WECAFC region. Several species which are not assessed by ICCAT are of considerable importance in large pelagic fisheries in the WECAFC region. Overall, about half the landings of large pelagics in the WECAFC region are from species which are assessed. Existing institutional mechanisms are not adequate for management of shared or straddling fish stocks and those of highly migratory fish, as per the recent UN Agreement. Any such institution must have linkages with extraregional organisations, primarily ICCAT, and, in order to maximise efficiency and avoid duplication, should also be able to deal with shared, straddling and migratory fish stocks other than pelagics, for example, lobster and reef fishes with planktonic early life history stages. WECAFC, with modifications to its statutes, appears to be the most feasible existing organisation to adopt such a role.

This book reviews and evaluates the scientific basis of U.S. management of fisheries for Atlantic bluefin tuna. In particular, it focuses on the issues of stock structure and stock assessments used by the National Oceanic and Atmospheric Administration's National Marine Fisheries Service for management under the International Convention for the conservation of Atlantic Tunas.

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.

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.

This review was developed as a project in response to the needs of the Intersessional Working Group of WECAFC in its task of identifying key options and priorities. The review describes a group of selected species that are considered to be important to Member States of the WECAFC. It classifies them into transboundary and straddling/highly migratory stocks and their fisheries and provides information on the state of exploitation of the selected species. The review also considers the ecological connectivity between the high seas and the EEZs of coastal nations. Lastly, it highlights issues that need to be addressed to generate a sound scientific knowledge base in support of the strategic reorientation of the Commission.

Annotation Tuna are biologically fascinating, with many specializations such as endothermy (warm-bloodedness), aerobic capacity, and migratory abilities. The primary focus of this book is the physiology of tuna with respect to biomechanics, thermoregulation, and morphology. An evolutionary and phylogenetic backdrop illustrates the importance of comparative perspectives. Because of the economic importance of tuna, a secondary focus of the book is tuna aquaculture and conservation.
