A Photographic Guide to Freshwater Fishes of New Zealand is the first comprehensive reference on New Zealand freshwater fishes since the publication of Bob McDowell's field guide (Heinemann Reed) over 12 years ago. It includes all freshwater fishes, both introduced and native fishes, with useful identification charts at the back of the book for bullies and whitebait (diadromous galaxids). Rod Morris has gone to great lengths to capture the very best images and numerous colour photographs through the book will assist in identifying the male and female of the species, and the subtle differences between related fishes. An extensive introduction includes highly topical coverage of freshwater ecology and conservation issues surrounding the quality of New Zealand's waterways, making this book an invaluable information resource. In addition, keen anglers will be delighted to find full entries on trout, salmon, and rudd, including rare hybrids. And mini-maps provided for each entry give an indication of the distribution of each species throughout the country.
