内容简介：
Fishes form the largest group of vertebrates, with around 20,000 known species, and they display a remarkable diversity of size, shape, internal structure and ecology to cope with environments ranging from transient puddles to the abyssal depths of the sea. Life in water leads to particular problems for body fluid regulation, locomotion and sensory systems, and these have been resolved in the most ingenious ways. This book, the first edition of which was published in 1982, has been largely rewritten to take account of recent information resulting from the huge rate of publication of scientific papers and books on fishes. Chapters on behaviour and on fisheries and aquaculture. A chapter on endocrines has also been added and all other chapters have been brought entirity up-to-date. The second edition includes a large number of illustrations. This is a textbook for students of fish biology and any of the branches of aquatic biology. Given its combination of breadth and detail, the book also provides a manageable review of fish biology for experienced biologists. Its wide-ranging bibliography is a special feature of the second edition.
