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.

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.

Fisheries resources are an important component of natural resources. It is an important source of high-quality animal protein and food for humans, which provides employment, economic benefits and social welfare for people engaged in fishing activities. It also has played an important role in food safety, economic development, and foreign trade. Fisheries resources economics is an important branch of both applied economics and resource economics. Its research object is fishery resources and its economic problems. The economics of fishery resources is to focus on the relationship between the demand for human economic activities and the supply of fishery resources, as well as between fishery resources and its development. This book expounds the reasons for the economic problems of fishery resources and the theoretical principles for solving them, so as to reveal the objective rules of the allocation of fishery resources in different regions and at different times, to coordinate the relationship between the utilization of fishery resources and economic development, and to realize the sustainable development of fishery economy. This book will also provide learning materials for undergraduates, graduate students and practitioners engaged in fishery resources development and scientific management.

The realization that many of the surveys which have been done in the past achieved little in relation to what could potentially have been gained, stimulated FAO to publish a series of manuals on resource surveys (Alverson 1971, Mackett 1973, Gulland 1975) which have set out ways of improving the quality of the data obtained from such surveys. However, there have been major advances in fisheries science since the earlier of these manuals was written, and accordingly it was decided, in 1976, that they should be updated and incorporated into a single volume covering all the major aspects of resource surveys.

A review of surveys carried out with the research vessel, Dr. Fridtjof Nansen, from 1975 to mid-1993 in the Indian, Atlantic and Pacific Oceans. The document includes an overview of survey methodology and a description of the development of the acoustic equipment used and the associated problems. Particular emphasis is placed on the surveys in the Arabian Sea.

The ten countries which border the Red Sea and Gulf of Aden depend to varying degrees on the area for their fish supplies with some countries such as South Yemen being totally dependent on the fish resources while to others, such as Israel and Jordan, the area is of minor importance. Catches of all fish species have been increasing slowly in recent years and in 1986 totalled 60.9 thousand tons from the Red Sea and 99.4 thousand tons from the Gulf of Aden. After reviewing the resource assessment and survey work which has been carried out in the area it was concluded that further increases in landings could be achieved on a sustainable basis. However such increases will come from the development of new fisheries and the expansion of the areas presently Fished rather than from traditional fisheries which are, in general, fully exploited. Utilization and marketing problems, particularly with small pelagic and mesopelagic species, however need to be addressed for the full potential of the area to be realized.

This publication updates the regular reviews of the state of the world's marine fishery resources, based mainly on official catch statistics throughout 2002 and relevant stock assessment and other complementary information available until 2004. It considers the global situation and major trends of world marine capture fish production, with detailed information for each FAO statistical area about catches and current state of exploitation, major trends and developments and stock assessment work undertaken in support of fisheries management. Other issues covered include: tunas and tuna-like species resources, world squid resources, deepwater fisheries, and long-term climate variability.
