Longlining is becoming increasingly more important as a method of fishing commercially for certain prime species of fish- particulary in the face of declining stocks. Longlining is much more selective that any other form of fishing and is thus more environmentally acceptable. Furthermore, longlining allows for the targeting of particular prime species and fish caught by this method are less damaged and thus hold a higher value. Despite the many major benefits of longlining, there are, as yet few books which address the technical and economic aspects of this method of commercial fishing. Written by an expert, this new book describes the principles and development of longlining fishing and explains the action of chemical sensing in fish and their behaviour towards baited hooks. Details of gear construction, the operation cycle for longlines, longline vessels and the different principles of mechanised baiting and on-board gear handling are provided and typical examples are given. The target species, gear parameters and catching efficiency, and the selective properties of longline gear are fully discussed whilst a concluding chapter compares longlining with other fishing methods.

In developing countries, traditional fishermen are important food contributors, yet technological information and development assistance to third-world nations often focuses on agriculture and industrial fishing, without addressing the needs of independent, small-scale fishermen. This book explores technological considerations of small-scale, primitive fishing technologies, and describes innovative, relatively inexpensive methods and tools that have already been successfully applied in developing countries. It offers practical information about all aspects of small-scale fishing, including boat design and construction, fishing methods and gear, artificial reef construction and fish aggregating devices, techniques for coastal mariculture, and simple methods for processing and preserving fish once they are caught. Fisheries Technologies for Developing Countries is illustrated throughout with photographs of the devices and construction methods described in the text.

Illegal, unreported and unregulated (IUU) fishing is a serious threat to sustainable fisheries, marine ecosystems and the livelihoods of legitimate fishers globally. To address it, the Common Oceans ABNJ Tuna Project is exploring ways to strengthen and harmonize the use of monitoring, control and surveillance tools, and combat IUU fishing in tuna fisheries across the marine areas beyond national jurisdiction.One tool is the use of electronic monitoring systems to monitor individual vessel operations at sea. In a typical electronic monitoring application, cameras, recording video or still images, are deployed at key points on the vessel to allow a view of the fishing operation. The video footage is stored on hard drives that government officials can use to review compliance with regulations, as well as record detailed data on catch and effort. It was envisaged that industry would have access to these data for its own operational purposes.To test the best way to incorporate this technology as complementary compliance tool, two pilot trials were set up: one in Ghana to cover the domestic tuna purse seine fleet fishing; and one in Fiji to cover the domestic longline fisheries. Close collaboration was established between national governments and industry for implementation.The overall aim of the pilots was to develop an effective implementation process at the national level, so that the information could be properly utilized for compliance purposes. This report documents the successful completion of these trials, and the lessons learned that could benefit electronic monitoring programmes elsewhere.

Feed your fascination with sharks! This complete resource enlightens readers on the biology, ecology, and behavior of sharks with approachable explanations and more than 250 stunning color illustrations. Studies of shark biology have flourished over the last several decades. An explosion of new research methods is leading to a fascinating era of oceanic discovery. Shark Biology and Conservation is an up-to-date, comprehensive overview of the diversity, evolution, ecology, behavior, physiology, anatomy, and conservation of sharks. Written in a style that is detailed but not intimidating by world-renowned shark specialists Dan Abel and Dean Grubbs, it relays numerous stories and insights from their exciting experiences in the field. While explaining scientific concepts in terms that non-specialists and students can understand, Abel and Grubbs reveal secrets that will illuminate even the experts. The text provides readers with a robust and wide range of essential knowledge as it • introduces emerging as well as traditional techniques for classifying sharks, understanding their behavior, and unraveling the mysteries of their evolution; • draws on both established shark science and the latest breakthroughs in the field, from molecular approaches to tracking technologies; • highlights the often-neglected yet fascinating subject of shark physiology, including heart function, sensory biology, digestion, metabolic performance, and reproduction; • addresses big picture ecological questions like "Which habitats do sharks prefer?" and "Where do sharks migrate and for what purpose?"; • describes the astonishing diversity of sharks' adaptations to their environment; • discusses which shark conservation techniques do and don't work; and • comments on the use and misuse of science in the study of sharks. Enhanced by hundreds of original color photographs and beautifully detailed line drawings, Shark Biology and Conservation will appeal to anyone who is spellbound by this wondrous, ecologically important, and threatened group, including marine biologists, wildlife educators, students, and shark enthusiasts.

There are many things and services in our everyday life that we take for granted, and telecommunications is one of them. We surf the internet, send emails to friends and colleagues abroad, talk to family members in foreign countries over the phone, book airline seats and make banking transactions without actually realizing and appreciating the sophisticated technology that enables us to do so. This report covers the history and nature of cables, their special status in international law, their interaction with the environment and other ocean users and, finally, the challenges of the future. It is an evidence-based synopsis that aims to improve the quality and availability of information to enhance understanding and cooperation between all stakeholders. UNEP-WCMC in collaboration with the International Cable Protection Committee and UNEP has prepared this new report to provide an objective, factual description of the sub-marine cable industry and the interaction of submarine telecommunications (which route 95% of all international communications traffic) with the marine environment. This important report seeks to focus and guide deliberations and decision making on the wise conservation and protection of the oceans in concert with their sustainable management and use.

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.
