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.

The parlous state of our freshwater ecosystems is just one signal that we face a more widespread, and unprecedented, environmental crisis. New Zealand’s dairy industry is big business. But what are the hidden – and not so hidden – costs of intensive farming? Evidence presented here by ecologist Mike Joy demonstrates that intensive dairy farming has degraded our freshwater rivers, streams and lakes to an alarming degree. This situation, he argues, has arisen primarily through governmental policy that prioritises short-term economic growth over long-term environmental sustainability. This BWB Text is a call to arms, urging New Zealand to change course or risk the wellbeing of future generations.

The management of water supply and quality in lakes, rivers, and reservoirs has proceeded largely on the basis of local rather than global considerations. High-quality freshwater resources are now in critically short supply, not only because of local problems such as over-irrigation and eutrophication, but also as a result of large-scale impacts such as climate effects on the hydrosphere. This book explores the dichotomy of global strategies (international and generic) versus local strategies (site-specific) for lake, river, and reservoir management, and presents a series of contrasting perspectives on topics that include monitoring, modeling, water treatment, eutrophication, and restoration. The final chapter integrates these perspectives and identifies strengths, weaknesses, and complementary aspects of the two approaches to help refine future strategies for the sustainable use of the world's freshwater resources.

The influence of Bernard Dussart's contributions to limnology in general as well as to freshwater copepodology in particular can hardly be overestimated. From 1945 until his decease late 2008, he has devoted more than 60 years of his life to studying freshwater bodies and their inhabitants. Next to his 200+ scientific papers, his frequent travels brought him all over the world, where he invariably left an inheritage of enhanced interest in problems of freshwater biology and management. The contributions in this book show the progress of research on the Copepoda found in continental waters and in part continue along the lines B. Dussart has set out: a worthy tribute to one of the very nestors of copepodology of fresh waters.
