Book excerpt: Excerpt from Experiments in Propagation of Freshwater Mussels of the Quadrula Group The fresh-water mussels of central North America with their heavy shells of beautiful pearl are a natural resource the value of which probably has not begun to be realized. The extensive development of the pearl-button industry in a brief period of 20 years is evidence of the wealth of the original natural supply; but a very evident decrease of readily obtainable shells, along with the increasing necessity for extension of clamming operations to more and more distant sources of supply, has made it evident that this resource is not unlimited.

This book was released on 2016-12-14 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Studies on the Reproduction and Artificial Propagation of Fresh-Water Mussels The writers' personal attention has in the main been directed to a study of the conditions of reproduction in the group and the parasitism of the larva in their bearing upon the problem of artificial infection of fishes with glochidia, while such phases of the investigation as geographical distribution, systematic studies, and a number of special ecological problems have been in the hands of other investigators. At the recently established biological station of the Bureau of Fisheries at Fairport, Iowa, while construction was still in progress, the work of propagating some of the commercial species was inaugurated, and the excellent facilities of the station, which has been especially designed for the purpose, are now being utilized by members of the stafi in attacking fundamental problems of both a scientific and an economic nature.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Protection of Fresh-Water Mussels The history of the fresh-water mussel industry gives illustration of the promptness with which an American industry may be developed once the pathway is found. Undertaken in a small way scarcely more than a score of years ago, the manufacture of pearl buttons began almost immediately to assume the proportions of an important national industry. As early as 1898, when the enterprise was only 6 years old, there were about 50 factories in more than a dozen towns along the Mississippi. With improved machinery and methods further expansion occurred, until within a few years the output approximated 30 million gross of buttons, with a value of many millions of dollars. The growth of the industry has continued to the present time, but exact figures will not be available until the Bureau has completed a statistical survey now in progress. Not less important has been a resultant economic change, or modification of custom, that has affected practically every person in the country. Where marine pearl was in rare use, fresh-water pearl, with its quality and price, came to fill a universal requirement. In one decade pearl buttons were high in price, used only upon the better clothing, and commonly saved when clothing was discarded, while in the most general use were buttons of metal or agate or wood, which rusted or broke or warped. In the next decade good pearl buttons, neat and durable, were available to everybody and used upon the widest variety of clothing. A former luxury had become a common necessity. Coincident with the rise of the manufacturing industry, there developed an important and widespread fishery, directly employing thousands of persons and indirectly affecting persons and communities of varied occupation.

Download or read book Freshwater Mussel Ecology written by David L. Strayer and published by Univ of California Press. This book was released on 2008-06-10 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
