The book is addressed mainly to Fishery Biologists but it is hoped that Fishing Gear Technologists also can acquire some basic knowledge of sampling problems and procedures which, in turn, can result in improved design of gears. The scope of these guidelines is limited to various techniques for capturing and observing fish at all stages of life. It is confined to inland waters, but a wide range of habitats in which fish can be sampled is recognized. Some of these techniques do not differ from those used in commercial or artisanal fisheries, but for sampling they should be used with understanding of the intricate relationships between fish and the gears in operation. The statistical aspects of sampling form an important part of this understanding. The other part is that related to construction and mode of operation of a gear. The reader should be able to choose a gear, or a set of devices, most suitable for his sampling programme out of those described here, although the guidelines do not offer detailed information on the construction of the gears.

This selection of methods is based on lecture notes used at a FAO/DANIDA training course held in Mombasa, Kenya, in May-June 1980. The methods presented are: regression and correlation, estimation of growth parameters from length-frequency data, estimation of mortalities (total, natural, fishing mortality) and analysis of catch and effort data. A brief annotated bibliography of tropical fish stock assessment is included.

It is now clear that data based on the studies of fish eggs and larvae make a number of unique contributions to fishery science that are crucial for accurate assessment and management of fish populations, including those of commercially important fisheries. This valuable book demonstrates why fish eggs and larvae are important, how the characteristics of early life stages require a somewhat different research approach and how information on early life stages can be applied and interpreted to yield unique insights into fish populations. The editors of Fishery Science have drawn together an extremely useful and well-written book with contributions from internationally respected researchers from North America, Asia and Europe. Chapters include a discussion of the unique nature of early life stages, age and growth, mortality, recruitment, populations analysis, habitats, human impacts and management. A carefully selected set of case studies demonstrates several specific applications of early life history information to a number of fishery problems. Fishery Science was designed to complement existing textbooks and is an essential purchase for all fisheries students and professionals, and for biologists working on the early life stages of fish. This exciting book is also of great value to ecologists, marine, freshwater and environmental scientists, populations biologists and oceanographers. All libraries in universities and research establishments where biological and fishery science are studied and taught should have copies of this book available on their shelves.

This bibliography is a compilation of selected references on the marking and tagging of aquatic animals, with special reference to information on different kinds of marks or tags that are available, techniques of applications, retention or recovery of marks or tags, and the effects of marks or tags on the organism. The references are arranged alphabetically byy author, consecutively numbered, and indexed by key words that enable easy access to references on particular subjects. The references are about equally divided between methods of marking fish and methods of marking other aquatic animals.
