Book Description
Techniques and theory for processing otoliths from tropical marine fish have developed only recently due to an historic misconception that these organisms could not be aged. Otoliths are the most commonly used structures from which daily, seasonal or annual records of a fish’s environmental history are inferred, and are also used as indicators of migration patterns, home range, spatial distribution, stock structure and life history events. A large proportion of projects undertaken on tropical marine organisms involve removal and processing of calcified structures such as otoliths, statoliths or vertebrae to retrieve biological, biochemical or genetic information. Current techniques and principles have evolved rapidly and are under constant modification and these differ among laboratories, and more particularly among species and within life history stages. Tropical fish otoliths: Information for assessment, management and ecology is a comprehensive description of the current status of knowledge about otoliths in the tropics. This book has contributions from leading experts in the field, encompassing a tropical perspective on daily and annual ageing in fish and invertebrates, microchemistry, interpreting otolith microstructure and using it to back-calculate life history events, and includes a treatise on the significance of validating periodicity in otoliths.

Book Description
This book provides a comprehensive attempt to adopt an 'integrated' interdisciplinary approach to the study of fisheries. Fisheries are discussed as holistic 'systems', with emphasis on their structure, operation and dynamics. The book's interdisciplinary approach is applied to an analysis of problems faced in pursuing 'sustainable fisheries', with emphasis on six dominant themes: sustainability, uncertainty, complexity, conflict, fishing rights and the nature of management. Within this discussion, several major directions in current fishery thinking are explored, notably the precautionary approach, the ecosystem approach, co-management, and robust management for resilient fisheries.

Book Description
This excellent second edition of Fisheries Biology, Assessment and Management, has been fully updated and expanded, providing a book which is an essential purchase for students and scientists studying, working or researching in fisheries and aquatic sciences. In the same way that excessive hunting on land has threatened terrestrial species, excessive fishing in the sea has reduced stocks of marine species to dangerously low levels. In addition, the ecosystems that support coastal marine species are threatened by habitat destruction, development and pollution. Open access policies and subsidised fishing are placing seafood in danger of becoming a scarce and very expensive commodity for which there is an insatiable demand. Positive trends include actions being taken to decrease the incidental catches of non-target species, consumer preferences for seafood from sustainable fisheries, and the establishment of no-take areas that provide refuges for marine species. But there is an urgent need to do more. Because there is an increasing recognition of the need to manage ecosystems as well as fish stocks, this second edition of this bestselling text book includes an additional chapter on marine ecology. Chapters on parameter estimation and stock assessment now include step-by-step instructions on building computer spreadsheet models, including simulations with random variations that realistically emulate the vagaries of nature. Sections on ecosystem management, co-management, community-based management and marine protected areas have been expanded to match the increased interest in these areas. Containing many worked examples, computer programs and numerous high quality illustrations, Fisheries Biology, Assessment and Management, second edition, is a comprehensive and essential text for students worldwide studying fisheries, fish biology, aquatic and biological sciences. As well as serving as a core text for students, the book is a superb reference for fisheries and aquatic researchers, scientists and managers across the globe, in both temperate and tropical regions. Libraries in all universities where fish biology, fisheries, aquatic sciences and biological sciences are studied and taught will need copies of this most useful new edition on their shelves.

Book Description
The report synthesizes the findings of ten case studies published in FAO Fisheries Technical Paper 426/2. The case studies have been conducted in five medium-sized lakes in the Democratic Republic of the Congo, Malawi, Zambia and Zimbabwe. The synthesis focuses on three features relevant for the SADC region: How has fishing effort developed in these lakes over the last 50 years? What causes changes in fishing effort? How do fishing effort and environmental factors compare in their effects on the regeneration of fish stocks?
