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.

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.

The definitive resource on tunas and billfishes from the world's top authorities. Tunas and billfishes are peak predators of the oceans. Admired by scientists and naturalists for their speed, grace, unique physiology, and diversity, they are important both ecologically and socioeconomically. Vital sources of food and income for many maritime nations, whose fleets of vessels target them with huge purse seines or miles-long lines, these exhilarating fishes are also highly desired and avidly sought by big game fishers across the globe. In Tunas and Billfishes of the World, Bruce Collette, a leading marine ichthyologist and conservationist, and John Graves, an expert on the biology, fisheries, and management of tunas and billfishes, focus on three families of fishes: Scombridae, the mackerels and tunas; Istiophoridae, sailfish and marlins; and Xiphiidae, the Swordfish. Over the course of 61 in-depth species accounts, Collette and Graves • describe what each species looks like and where it lives • include detailed summaries of the fishes' biology—size, food, habitat, reproduction, and early life history • offer current information about fisheries interests and conservation status • provide up-to-date evaluations of the threat status for each species Accompanied by full-color, scientifically accurate illustrations by renowned illustrator Val Kells, along with range maps for each species, this spectacular volume is the essential book on these majestic inhabitants of the sea. Destined to quickly become the standard reference for scientists, students, and naturalists, Tunas and Billfishes of the World will also be prized by all fishers who pursue these species.

Weaknesses in understanding of tuna distributions and movements have constrained the development of rational management policies. Uncertainties exist in: the selection of management plans and catch and effort data that are representative of a stock; quantification of exchange of adults among management jurisdictions and fishing gears; and identification of the relationships between the environment and tuna movements. This report summarizes a series of discussions between a panel and groups of experts on how to increase understanding of these and other tuna problems. We discuss the uncertainties in current management policy caused by lack of understanding of tuna movement dynamics. We describe and evaluate the research approaches presently used to describe the movements of tunas--mark and recapture and acoustic tracking-- and those which might be used or are just being applied, including new tagging systems, measurement of physiological state and microconstituents of mineralized tissue. Actions needed to improve the knowledge of tuna movements are: 1) establish international arrangements to share tuna movement data, to analyse movements on an oceanwide and worldwide basis and to link international oceanographic programs; 2) increase number and kinds of observations of movements of tuna in the vertical plane; 3) develop and use technology for tracing the actual paths followed by tunas over extended periods and for measuring movements independent of the fishery; and 4) conduct intensive studies on tuna movement dynamics which combine old with the new technologies discussed in the report.
