With more than 29,000 species, fishes are the most diverse group of vertebrates on the planet. Of that number, more than 12,000 species are found in freshwater ecosystems, which occupy less than 1 percent of the Earth’s surface and contain only 2.4 percent of plant and animal species. But, on a hectare-for-hectare basis, freshwater ecosystems are richer in species than more extensive terrestrial and marine habitats. Examination of the distribution patterns of fishes in these fresh waters reveals much about continental movements and climate changes and has long been critical to biogeographical studies and research in ecology and evolution. Tim Berra’s seminal resource, Freshwater Fish Distribution,maps the 169 fish families that swim in fresh water around the world. Each family account includes the class, subclass, and order; a pronunciation guide to the family name; life cycle information; and interesting natural history facts. Each account is illustrated, many with historical nineteenth-century woodcuts. Now available in paperback, this heavily cited work in ichthyology and biogeography will serve as a reference for students, a research support for professors, and a helpful guide to tropical fish hobbyists and anglers.

Methods in Stream Ecology, Second Edition, provides a complete series of field and laboratory protocols in stream ecology that are ideal for teaching or conducting research. This updated edition reflects recent advances in the technology associated with ecological assessment of streams, including remote sensing. In addition, the relationship between stream flow and alluviation has been added, and a new chapter on riparian zones is also included. The book features exercises in each chapter; detailed instructions, illustrations, formulae, and data sheets for in-field research for students; and taxanomic keys to common stream invertebrates and algae. With a student-friendly price, this book is key for all students and researchers in stream and freshwater ecology, freshwater biology, marine ecology, and river ecology. This text is also supportive as a supplementary text for courses in watershed ecology/science, hydrology, fluvial geomorphology, and landscape ecology. - Exercises in each chapter - Detailed instructions, illustrations, formulae, and data sheets for in-field research for students - Taxanomic keys to common stream invertebrates and algae - Link from Chapter 22: FISH COMMUNITY COMPOSITION to an interactive program for assessing and modeling fish numbers

This book is an up to date compendium of all information available up to 1997 in respect of the freshwater fish fauna of this region . The classification adopted is generally after Nelson's Fishes of the World (1994), Howes (1991) with inputs from Eschmeyer's Genera of Fishes (1990). For Cyprinine genera the order of an arrangement proposed by Rainborth (1991) has been adhered to. In respect of nemacheilines the arrangement proposed by Banarescu and Nalbant (1995), Kottelat (1990) have been followed. As indicated in the title the Indian region as conceived here includes India, Pakistan, Bangladesh, Mayanmar, Nepal and Sri Lanka within their political boundaries. Afghanistan and other border areas excluded. All primary freshwater fishes are definitely listed and many secondary and peripheral species that visit freshwater are also included. A uniform pattern of citation is adopted. Brief salient features of all the taxa up to orders are given. Descriptive details in respect of families and genera are provided more elaborately. Synonymies include the latest valid name, first reference, type-designations and more important pertinent references to that taxa. All citations have been checked, and cross-checked with the aid of Eschmeyer's work. Species are not described but listed alphabetically with their known range of distribution, but genera are described and arranged according to their known phylogenetic and intergeneric affinities. Keys are provided and simple drawings illustrating characters where needed are given. Synonyms, notes on species, genera, nomenclatural clarifications are given as foot-notes against relevant species marked with an asterisk, but in the foot-note the same serial number alone is cited and not the full species name. Figures depicting a representative of most genera can be seen; for many genera the more common species are illustrated as plate figures. A total of 272 genera with 852 species falling under 71 families and 16 orders are dealt with in this book. A glossary of 218 technical terms with adequate illustrations and a bibliography of 649 references are given. 241 figures and 18 plates are in the book. An addenda made up to date carries brief information of one new genus, 11 new species and one new subspecies.
