This much-needed text, a companion to Fisheries Techniques, is designed as both a reference and a handbook for the study of fishes. It is a source of methods commonly used to research fish genetics, systematics, anatomy, physiology, developmental biology, toxicology, behavior, and ecology. Each of its 20 chapters also provides a comprehensive introduction to the literature of its field.

An excellent teaching text and reference book. This book is intended for fisheries professors, fisheries students, professional biologists, technicians, administrators, and
