Goldfish Varieties and Genetics

The goldfish, Carassius auratus, a member of the Carp family, Cyprinidae, has been domesticated fGoldfish Varieties and Geneticsor many hundreds of years, as a food fish, a laboratory animal and now most important commercially, for ornamental and aesthetic purposes. There are now many scores of recognised varieties, which have been produced over time by selection processes and other methods described in detail in this stimulating book.

Goldfish Varieties and Genetics covers all major aspects relating to goldfish breeding and genetics in a readable and user-friendly style. An account is presented of the domestication and evolution of the goldfish, including comprehensive details of the relevant genetic and biological principles involved in the development strategies and production of new varieties. The book also covers the subject of goldfish appreciation and the international significance of goldfish shows and show standards. The book concludes with an exciting forward look at the potential evolutionary future for the goldfish.

This important and timely book brings together, for the first time, a wealth of scientific information, presented in a clear and understandable manner by Dr Joseph Smartt, who has many years' experience working in fish genetics and breeding. The book is a must-have purchase for all serious goldfish breeders, hobbyists and dealers, fish biologists and geneticists, aquarium keepers and aquaculture personnel.

Return to the River: Restoring Salmon Back to the Columbia River

Return to the River will describe a new ecosystem-based approach to the restoration of salmon and steelhead populations in the Columbia Return to the River: Restoring Salmon Back to the Columbia RiverRiver, once one of the most productive river basinsfor anadromous salmonids on the west coast of North America. The approach of this work has broad applicability to all recovery efforts throughout the northern hemisphere and general applicability to fisheries and aquatic restoration efforts throughout the world.

The Pacific Northwest is now embroiled in a major public policy debate over the management and restoration of Pacific salmon. The outcome of the debate has the potential to affect major segments of the region's economy - river transportation, hydroelectric production, irrigated agriculture, urban growth, commercial and sport fisheries, etc. This debate, centered as it is on the salmon in all the rivers, has created a huge demand for information. The book will be a powerful addition to that debate.

* A 15 year collaboration by a diverse group of scientists working on the management and recovery of salmon, steelhead trout, and wildlife populations in the Pacific Northwest
* Includes over 200 figures, with four-color throughout the book
* Discusses complex issues such as habitat degradation, juvenile survival through the hydrosystem, the role of artificial production, and harvest reform
