An Entirely Synthetic Fish
Anders Halverson provides an exhaustively researched and grippingly rendered account of the rainbow trout and why it has become the most commonly stocked and controversial freshwater fish in the United States. Discovered in the remote waters of northern California, rainbow trout have been artificially propagated and distributed for more than 130 years by government officials eager to present Americans with an opportunity to get back to nature by going fishing. Proudly dubbed an entirely synthetic fish by fisheries managers, the rainbow trout has been introduced into every state and province in the United States and Canada and to every continent except Antarctica, often with devastating effects on the native fauna. Halverson examines the paradoxes and reveals a range of characters, from nineteenth-century boosters who believed rainbows could be the saviors of democracy to twenty-first-century biologists who now seek to eradicate them from waters around the globe. Ultimately, the story of the rainbow trout is the story of our relationship with the natural world--how it has changed and how it startlingly has not.

Nutrition and Feeding of Rainbow Trout
This special publication is designed to describe the basic elements of salmonid nutrition. Described are the requirements and functions of nutrients. The feed formulation for salmonids is described, together with the quality control parameters for the most important ingredients in salmonid diets. All fish feeds must be processed to produce feed particles of appropriate size for fish of different ages and sizes. The digestibility and balance of nutrients assumes greater importance in diets for fish because of the importance of preventing eutrophication and increasing the biological oxygen demand in the fish pond. Guides have been established indicating the amount of feed to give daily to fish of various sizes and water temperatures. Fish are poikilotherms whose body temperature, metabolic rate and feeding activity varies with the ambient water temperature. Feeding rates and growth rates are reduced as the temperature is decreased from 15 to 4 C.
