Commences with a discussion of biological and statistical considerations involved in designing an effective survey. Examines sampling equipment and techniques used in conducting direct surveys with equal attention to trawl, acoustic, ichthyoplankton and sighting studies. Alternative approaches used in each type of survey are reviewed and numerous case histories illustrate successful applications.

Ocean harvests have plateaued worldwide and many important commercial stocks have been depleted. This has caused great concern among scientists, fishery managers, the fishing community, and the public. This book evaluates the major models used for estimating the size and structure of marine fish populations (stock assessments) and changes in populations over time. It demonstrates how problems that may occur in fisheries dataâ€"for example underreporting or changes in the likelihood that fish can be caught with a given type of gearâ€"can seriously degrade the quality of stock assessments. The volume makes recommendations for means to improve stock assessments and their use in fishery management.

For two decades the idea of governments and fishers working together to manage fisheries has been advocated, questioned, disparaged and, most importantly, attempted in fisheries from North and South America through Europe, Africa, Asia and Oceania. This book is the first time these experiences have been pulled together in a single volume, summarized and explained. The Fisheries Co-management Experience begins with a review of the intellectual foundations of the co-management idea from several professional perspectives. Next, fisheries researchers from six global regions describe what has been happening on the ground in their area. Finally, the volume offers a set of reflections by some of the best authors in the field. The end result describes both the state-of-the-art and emerging issues for one of the most important trends in natural resources management.

This handbook summarises the experience gained over recent years in fishery statistical development by the Fishery Information, Data and Statistics Unit of the FAO, and provides guidance for developing and implementing cost-effective and sustainable fishery surveys. The methodological and operational concepts discussed apply equally to marine and inland capture fisheries. The emphasis is placed on the understanding and interpretation of the statistics, rather than on the computations producing them.

The Ecology of Sandy Shores provides the students and researchers with a one-volume resource for understanding the conservation and management of the sandy shore ecosystem. Covering all beach types, and addressing issues from the behavioral and physiological adaptations of the biota to exploring the effects of pollution and the impact of man's activities, this book should become the standard reference for those interested in Sandy Shore study, management and preservation. - More than 25% expanded from the previous edition - Three entirely new chapters: Energetics and Nutrient Cycling, Turtles and Terrestrial Vertebrates, and Benthic Macrofauna Populations - New sections on the interstitial environment, seagrasses, human impacts and coastal zone management - Examples drawn from virtually all parts of the world, considering all beach types from the most exposed to the most sheltered

This auto-translation book overviews the fish population and its research methods, help readers in understanding the concept of fish population and population identification. It divides into seven chapters according to the characteristics of the subject and the development results. Based on a systematic introduction to the basic concepts and research contents of the biology of fishery resources, the book focuses on the introduction of fish populations and research methods, life history division and early development identification, age identification and growth research, the division of sexual maturity, the determination of reproductive habits and fecundity, feeding characteristics and research methods of fish, and the mechanism of fish colony and migration. Through the study of this course, we can master the basic theory and methods of fish biology research and lay a solid foundation for future researches on fishery resources. This book can be used as a reference book for undergraduates and postgraduates who study fishery resources, as well as for those who are engaged in fishery and marine research. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content.
