Book Description
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.

Book Description
A perfect fish in the evolutionary sense, the broadbill swordfish derives its name from its distinctive bill—much longer and wider than the bill of any other billfish—which is flattened into the sword we all recognize. And though the majesty and allure of this warrior fish has commanded much attention—from adventurous sportfishers eager to land one to ravenous diners eager to taste one—no one has yet been bold enough to truly take on the swordfish as a biographer. Who better to do so than Richard Ellis, a master of marine natural history? Swordfish: A Biography of the Ocean Gladiator is his masterly ode to this mighty fighter. The swordfish, whose scientific name means “gladiator,” can take on anyone and anything, including ships, boats, sharks, submarines, divers, and whales, and in this book Ellis regales us with tales of its vitality and strength. Ellis makes it easy to understand why it has inspired so many to take up the challenge of epic sportfishing battles as well as the longline fishing expeditions recounted by writers such as Linda Greenlaw and Sebastian Junger. Ellis shows us how the bill is used for defense—contrary to popular opinion it is not used to spear prey, but to slash and debilitate, like a skillful saber fencer. Swordfish, he explains, hunt at the surface as well as thousands of feet down in the depths, and like tuna and some sharks, have an unusual circulatory system that gives them a significant advantage over their prey, no matter the depth in which they hunt. Their adaptability enables them to swim in waters the world over—tropical, temperate, and sometimes cold—and the largest ever caught on rod and reel was landed in Chile in 1953, weighing in at 1,182 pounds (and this heavyweight fighter, like all the largest swordfish, was a female). Ellis’s detailed and fascinating, fact-filled biography takes us behind the swordfish’s huge, cornflower-blue eyes and provides a complete history of the fish from prehistoric fossils to its present-day endangerment, as our taste for swordfish has had a drastic effect on their population the world over. Throughout, the book is graced with many of Ellis’s own drawings and paintings, which capture the allure of the fish and bring its splendor and power to life for armchair fishermen and landlocked readers alike.

Book Description
This handbook provides guidance on methods for use in fish ageing studies. Fish age, among other biological parameters, is one of the most relevant pieces of data to attain sustainable exploitation levels of fishery resources. Indeed, most analytical methods used in stock assessment require knowledge of demographic structure according to age of stocks, as well as to recruitment, growth, maturity, natural mortality, etc., which are strictly linked to information on age and age structure. The handbook was put together to deal with identified gaps – which affect both the precision and the accuracy of estimations – regarding ageing schemes, criteria and methodologies used in preparing calcified structures. It focuses on the general principles that underpin age analysis (assignment of birth date, preparation methods, aging scheme reading and identification of true and false rings). Crucially, it aims to contribute to the establishment of common analysis methods, which can enable better calibration across the diverse institutes involved, thereby improving the quality and reliability of results.

Book Description
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.
