Despite the fact hat longline fishing is a traditional and widespread fish capture method, few books describe in detail the principles and applications of longline fishing gear.

Longlinning has been written to provide all the information needed on the many different aspects of longline fishing. It deals the history of the technique, the basic capture principles and how they relate to fish behaviour, important target species, and provides technical descriptions of gear, vessels ad equipment and the different modes of operating longlines. A comparison with other methods of fishing is also...

Salmon aquaculture is one of the most rapidly developing industries in temperate ocean waters throughout the world. Under the expert guidance of three world authorities, an international team of contributing authors examine the underlying elements which have contributed to the accelerated growth of this industry and the likely consequences upon and for the industry as a whole. This volume carries a wealth of knowledge and practical information on major biological, technical and economic aspects of salmon aqauculture through all stages of activity ranging from broodstock to market.

The new edition of this text continues to offer a essential information and practical guidance for all involved in freshwater fisheries management in temperate regions. The whole text has been fully revised and many sections have been completely rewritten to cover the many advances and developments of the last decade.

In the sixteen years since the last edition of Von Brant's classic work was published, fishing and fisheries have undergone vast changes. Not only has there been great progress in the development of new tools, materials and techniques, but the industry has seen an increasing need to address controversial issues such as declining fish stocks, enormous quantities of bycatch and discard and the impact of towed fishing gear on the environment. Fully revised and updated to reflect such changes, the fourth edition of this widely read and popular book offers:

Fully updated new edition Much new information on fertilisation, feeding, stocking, pond aeration Authors are well known for their work on these species Carp and other cyprinids are of huge commercial importance.

The current high demand for fish and increased awareness of the role of the environment in supporting human well being has led to a situation where attitudes to inland water resources are changing rapidly.

Trends in resource use and environmental impact are very evident in inland waters which are particularly vulnerable as they act as collectors of all the activities occurring in their basins and rank as some of the most endangered ecosystems in the world. The principle changes influencing the evolution of the aquatic resource for fisheries are described in this book, which has been...

Over recent years there have been major advances in the application of molecular, biotechnological and genetic techniques to a wide range of aquatic species. Until now, many working in a hands-on capacity in the area of aquaculture have not known what the benefits of this work could be to them. This important new book redresses this situation, providing clear details of the available scientific information and the direct application of techniques under simple and practical situations.

As the world's population and the demand for seafood increase, the production of seafood from aquaculture has also seen massive increase and is set to continue. With wild stocks of many molluscan species depleted, aquaculture is firmly recognised as the means now, and for the future, of bridging the gap between the supply and demand of seafood.

This important book covers the general biology of bivalves, hatchery culture methods and specific and comprehensive details of the cultivation of many commercially important species, including clams, oysters, mussels, scallops...

Despite their importance in terms of employment and income generation, inshore fisheries have been a neglected area of study. The review of the common fisheries policy, especially in the light of the need to re-examine the derogation which reserves access to the inshore zone to coastal state vessels, provides an opportunity to redress the balance. With contributions from leading authorities on fisheries management, the book takes an in-depth look at seven European countries, examining the basis for the definition of inshore fisheries, evaluating their status, and describing the salient...

This book represents the Proceedings of the 37th European Marine Biology Symposium, held in Reykjavik, Iceland, 5-9 August 2002. The main themes of the symposium were Migrations and Dispersal of Marine Organisms. These themes are highly relevant today. There is widespread man-aided dispersal (e.g. by ballast water) of marine plants and animals, which may have substantial effects on the regions receiving new species. The new introductions may result in reduced diversity of plants and animals and may affect natural resources in the countries receiving toxic algae and other foreign elements....

This book arises from case studies and two back-to-back workshops held in Cotonou, Benin in November 2001. They were the combination of much experience and knowledge gathered in the West Africa region and were brought about to explore the concept of poverty, especially how it is a part of the life of fishing communities and our ways of thinking about resolving the issue. The workshops were conceived as a partnership between the UK Department for International Development (DFID), the Food and Agriculture Organization of the United Nations (F AO) and 25 countries of West Africa, working...

This book deals with the processes behind cycles of the phosphate and nitrogen compounds in sediment and the phosphate equilibria between the sediment and the overlying water. In most waters, excessive concentrations of these compounds causes eutrophication: rapid, choking growth of algae. The chapters of this book probe the chemicals involved in considerable detail, and offer the complete understanding needed to remediate or prevent pollution problems.

Covering all aspects of subsistence and commercial aquaculture as practiced across the globe, this fully revised new edition from two leading world authorities in the field is set in two parts: principles and practices, and covers in detail recent developments in: * History and planning * Nutrition * Reproduction and genetic selection * Production statistics and economics * Integrated aquaculture * Sustainability and environmental effects (new chapter) All cultured species groups are addressed, from freshwater and marine fish to shellfish and seaweeds. Essential new facts and data have been...

Celebrating the centenary of the Centre for Environment Fisheries and Aquaculture Science (CEFAS) Fisheries Research Laboratory at Lowestoft, UK, this peer-reviewed, edited tome discusses four interwoven themes:
- The consequences and management of unregulated/unreported catches
- Competition
- External drivers and resource behaviour
- Ecosystems and migration

With contributions from fisheries scientists, policy-makers and managers from more than twenty countries, this international volume has evolved from the CEFAS symposium on...

Since the first edition of this book, 17 years ago, aquaculture has consolidated its position as an important means of producing food and as a contributor to global food security. Cage aquaculture too has continued to expand apace. The third edition of this important, useful and well-received book maintains the original aim of providing a thorough synthesis of information on cages and cage aquaculture practices with data and examples encompassing all major world regions.Fully updated, the book 's comprehensive contents include details of the origin and principles of cage aquaculture and an...

The scallop farming industry continues to expand, providing an important global source of food and revenue. In recent decades over-fishing has caused a decline in wild stocks and as consumer demand increases, the opportunities for new and existing scallop farming ventures are greater than ever before.

In this important new edition, experienced scallop farmer David Hardy offers the reader:

• Practically oriented advice


• New technical, environmental and legislative information


• Key information for running a successful farming...

Recreational or sports fishing is a multi-billion dollar industry worldwide and in many countries represents an important social and cultural activity. In some regions, it also contributes significant income to tourism and tackle businesses. In addition to its importance from a social and economic standpoint, the impact of recreational fishing on the environment and on food webs can often be substantial.

This important book represents the major output from the 4th World Recreational Fishing Conference held in Norway in June 2005. The conference focused on several topics and targeted...

This second edition contains new information on analytical tools in use in fisheries, ecology and acquatic sciences and includes a new chapter on environmental influences on ecology and the aquatic environment.

Although this book provides information on warmwater aquaculture in the United States that should be useful to aquacultural suppliers, lending institutions, resource managers, interested citizens, and others, the principal purpose is to tell the fish farmer what is to be done, why it is to be done, and how to do it. The reader is provided with the essentials of successful warmwater fish farming. The emphasis in this book is clearly on channel catfish, ranging from maintenance of brood stock to the culture of fingerlings and the production of market-sized fish. However, production techniques...
