It is specifically to the need for instruction of keepers of coldwater marine life, whether hobbyist, dealer, public aquarist, aquaculturist, laboratory animal technician or fisheries biologist, that this work is directed. The Coldwater Marine Aquarium combines descriptive language and hard numbers in a way that meaningfully depicts the complexities of coldwater seascapes. The emphasis on biogeography in this book is strong, and not inadvertently so. Arguably, any serious marine aquarist should be at least a little conversant with certain fundamental oceanographic and ecological concepts. In that respect, it is hoped that this work serves well in rounding out the bookshelf of frankly any kind of aquarist. But it is especially incumbent upon temperate and deep-water marine aquarists (who have a special penchant for biotope aquaria) to have some biogeographic knowledge of the marinelife in their keep. To that end, a wealth of pertinent field data is given to assist in the recreation of distinct biotopes. A generous assemblage of full-color images provides many vivid examples of topics discussed in the text. 105 pages, 52,592 words.
