From beer labels to literary classics like A River Runs Through It, trout fishing is a beloved feature of the iconography of the American West. But as Jen Brown demonstrates in Trout Culture: How Fly Fishing Forever Changed the Rocky Mountain West, the popular conception of Rocky Mountain trout fishing as a quintessential experience of communion with nature belies the sport's long history of environmental manipulation, engineering, and, ultimately, transformation.

A fly-fishing enthusiast herself, Brown places the rise of recreational trout fishing in a local and...

Fish nutrition can be the deciding factor between a robust and healthy farmed fish population and low aquaculture production. In an age where chemicals and antibiotics are under greater scrutiny than ever, a strong understanding of the role of nutrients and feed additives is essential in the aquaculture industry.

Dietary Nutrients, Additives and Fish Health is a comprehensive review of dietary nutrients, antinutritional factors and toxins, and non-nutrient dietary additives, and their effects on fish performance and immune system function, as well as overall health.

For centuries, borders have been central to salmon management customs on the Salish Sea, but how those borders were drawn has had very different effects on the Northwest salmon fishery. Native peoples who fished the Salish Sea--which includes Puget Sound in Washington State, the Strait of Georgia in British Columbia, and the Strait of Juan de Fuca--drew social and cultural borders around salmon fishing locations and found ways to administer the resource in a sustainable way. Nineteenth-century Euro-Americans, who drew the Anglo-American border along the forty-ninth parallel, took a very...

Biologists have long marvelled at how anadromous salmonids ? fish that pass from rivers into oceans and back again ? survive as they migrate between these two very different environments. Yet, relatively little is understood about what happens to salmonids in the estuaries where they make this transition from fresh to salt water. This book distills the current knowledge of how eighteen salmonid species around the world (including salmon, steelhead, char, and trout) are adapted to estuaries. It discusses why the waters where rivers and oceans meet are critical to salmonid survival as well...

The competitive and social behaviors of this species are unusually complex for an amphibian. This species is...
