Man has been intrigued by the origin of pearls, sensitive to their beauty, and convinced of their medicinal value for at least 5 cent. A mixture of folklore and observation preceded the earliest scientific inquiries. Fishing and trade commenced in S. Asia, between India and Sri Lanka and around the Persian Gulf. In W. and Central Europe, Inner Asia and China, and N. Amer. Freshwater pearls were probably known and treasured before those of marine origin. A refined nomenclature points to a long familiarity with etymologically related words for 'pearl'. Pearls were prominent among the luxury products of world trade and were high among the objectives of expeditions to the eastern and western Tropics. Illustrations.

Since the early 1800s, people have made a living fishing and harvesting mussels in the lower Ohio Valley. These river folk are conscious of an occupational and social identity separate from those who earn their living from the land. Sustained by a shared love of the river, deriving joy from the beauty of their chosen environment, and feeling great pride in their ability to subsist on its wild resources and to master the skills required to make a living from it, many still identify with the nomadic houseboat-dwelling subculture that flourished on the river from the early nineteenth century to the 1950s. Today's community of fisherfolk is small and economically marginal, but their activities sustain a complex set of traditional skills and a body of verbal folklore associated with river life. In Flatheads and Spoonies, Jens Lund describes the activities, boats, gear, verbal lore, and sense of identity of the fisher folk of the lower Ohio River Valley and provides historical and ethnobiological background for their way of life. Lund connects the importance of river fish in the diet of inhabitants of the valley to local fishing activities and explores the relationship between river people and those whose culture is primarily land-based, painting a colorful portrait of river fishing and river life. This book offers a look—historical and ethnographic—at a little-known aspect of traditional life in the American Midwest, still surviving today despite immense changes in environment, resources, and economic base.

Pearly mussels (Unionoidea) live in lakes, rivers, and streams around the world. These bivalves play important roles in freshwater ecosystems and were once both culturally and economically valuable as sources of food, pearls, and mother-of-pearl. Today, however, hundreds of species of these mussels are extinct or endangered. David L. Strayer provides a critical synthesis of the factors that control the distribution and abundance of pearly mussels. Using empirical analyses and models, he assesses the effects of dispersal, habitat quality, availability of fish hosts, adequate food, predators, and parasites. He also addresses conservation issues that apply to other inhabitants of fresh waters around the globe and other pressing issues in contemporary ecology.
