Book Description
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.

Book Description
This atlas aims to present sound approaches to maturity sampling for a wide range of Mediterranean species – including bony fish, cartilaginous fish, both oviparous and viviparous, crustaceans and cephalopods – based on an accurate determination of the different maturity stages. It includes macroscopic photos of gonads belonging to the main species and, for some, a validation-based histological analysis.

Book Description
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.

Book Description
The final report forms Part I of the volume, and reviews our knowledge of distributional patterns of commercial invertebrates (conch and lobster), demersal and small and large pelagic fish stocks occurring in the Lesser Antilles subregion of the WECAF Commission area, and on the basis of existing information, places these resources in objective categories from a fisheries management perspective. The main options for management of domestic and foreign fishing are outlined. Part II contains background documents on a variety of topics, including reviews of the existing data base on invertebrates and demersal fish stocks, swordfish and oceanic pelagics. An objective classification of stocks by mode of sharing is presented, foreign fishing activity in the subarea is reviewed, and seasonality and migrations of pelagic fish discussed. An overview of options for shared stock management is also included.

Book Description
The FAO Fishery and Aquaculture Circular C942 Revision 3 (C942 Rev. 3) updates and expands the scope of previous revisions of the circular. C942 Rev. 3 is an important baseline document, intended to assist in the global understanding of inland fisheries and inform dialogue on their current and future role. The third revision reviews the status and trends of inland fisheries catch at global, continental and subcontinental levels. It places inland capture fisheries in the context of overall global fish production, and calls attention to the importance of inland capture fisheries with respect to food security and nutrition and the Sustainable Development Goals. It quantifies global inland fisheries resources in terms of food production, nutrition, employment, economic contribution with respect to those countries/regions or subnational areas where they are important. A characterization approach to distinguish large-scale and small-scale fishing operations and their relative contributions is provided. The review provides estimated economic values of inland fisheries, as well as a valuation of potential replacement cost of these (in terms of dollars, other resources such as land and water, feeds). There is also an analysis of the extent and economic value of recreational inland fisheries. The contribution to employment and the gender differences related to this are quantified. The linkages between inland fisheries and biodiversity are also explored. C942 Rev. 3 discusses ways to measure and assess inland fisheries, in particular, how to establish more accurately inland fishery catches in the many situations where there are challenges to collection of catch statistics.

Book Description
Fisheries Biology Assessment and Management is a core text which provides essential information and expert guidance on modern methods of resources management for both temperate and tropical fisheries, and is directed to students of marine science and biology and fisheries researchers, scientists, and managers. Modern catching methods are reviewed in full, analyses of fisheries resource species are provided, from invertebrates (such as sea cucumbers) to migratory fish species (such as tuna) and, unlike other available texts, Fisheries Biology Assessment and Management contains a large number of worked examples and numerous graphs, charts, diagrams and line drawings. Destined to become the foundation text and leading reference in this vital area of fisheries science.

Book Description
The main species of holothurian exploited in the South Pacific are Holothuria scabra, H fuscogilva and H. nobilis, which have high commercial value, Actinopyga echinites, A. miliaris and Thelenota ananas, of medium commercial value, and Holothuria atra, H. fuscopunctata and H mauritiana, whose commercial value is low. Knowledge of the biology of these species is reviewed in detail, as are resource assessment methods. An example of the possible use of remote sensing for estimating potential is given. Harvesting and processing techniques and commodity grading are also discussed, while a chapter focussing on the principal markets for bêche-de-mer, Hong Kong and Singapore concludes that an increase in exports from the countries and territories of the South Pacific is possible if they can supply a consistently good-quality product on a regular basis.
