New Zealand has a rich and varied assortment of rivers, streams, lakes and wetlands that are home to a modest but really fascinating and varied freshwater fish fauna. For many years this fauna was known to only a small group of specialists and devotees but, over the past few decades, an increasing number of naturalists, conservationists and anglers have begun to discover the attractions and fascination of these fishes. The Reed Field Guide to New Zealand Freshwater Fishes is a complete and easy-to-read reference to the fishes throughout New Zealand and her outlying islands, such as the Chathams. Each entry contains colour photographs, a line drawing and a distribution map and information on size, colour, features particular to the type of fish, distribution, habitat and diet.

In many ways, this book is the culmination of more than four decades of my exp- ration of the taxonomy, biogeography and ecology of New Zealand’s quite small freshwater fish fauna. I began this firstly as a fisheries ecologist with the New Zealand Marine Department (then responsible for the nation’s fisheries research and mana- ment), and then with my PhD at the Museum of Comparative Zoology at Harvard University, Cambridge, MA, USA in the early–mid 1960s. Since then, employed by a series of agencies that have successively been assigned a role in fisheries research in New Zealand, I have been able to explore very widely the natural history of that fauna. Studies of the fishes of other warm to cold temperate southern lands have followed, particularly southern Australia, New Caledonia, Patagonian South America, the Falkland Islands, and South Africa and, in many ways, have provided the rather broader context within which the New Zealand fauna is embedded in terms of geography, phylogeny, and evolutionary history, and knowing this context makes the patterns within New Zealand all the clearer. An additional stream in these studies, in substantial measure driven by the beh- ioural ecology of these fishes round the Southern Hemisphere, has been exploration of the role of diadromy (regular migrations between marine and freshwater biomes) in fisheries ecology and biogeography, and eventually of diadromous fishes wor- wide.

"This landmark publication draws together all that has ever been written about the role of freshwater fishes in the lives of early Maori. Species such as tuna (eels) kanakana (lamprey), inanga and kokopu were of high importance in the traditional diets of Maori, who were well aware of the places and seasons in which these fish could be harvested. Bob McDowall has made it his life's work to read every word ever written on the subject of Maori fisheries, from passing references in explorers' diaries, to the significant literary achievements of Elsdon Best and Te Rangi Hiroa in the 1920s, to the recent reports of the Waitangi Tribunal. In Ikawai, all the knowledge on record is connected into a coherent account for the first time, and interpreted in the light of modern scientific knowledge of the fish fauna. As well as being highly informative, Ikawai also serves to illustrate the beauty associated with Maori fisheries. Bob has amassed an extraordinary collection of photographs of the fish themselves, of the artefacts Maori customarily used in catching fish, and of artworks by modern Maori practitioners, some reflecting the many legends and stories associated with fish. He has also unearthed some stunning and highly significant historical images that were hidden away in archives, libraries and photographic collections. This compendium is an essential resource for anyone interested in the lives and livelihood of New Zealand's earliest settlers." --Publisher.
