Scrutinizing the people, policies, institutions, and issues tied to the shrimping industry in Mississippi, Paul Durrenberger provides this first examination ever of the complexities of an American fishing industry in a single geographical area. He presents an analysis of one elaborate system--from the toils and turmoils of the people who catch the shrimp to the quandaries facing the policymakers who try to regulate them.

The shrimping industry, he contends, occurs on a series of interrelated levels and dimensions and is influenced by the ideas and actions of shrimpers, processors, fisheries managers, bureaucrats, creditors, environmentalists, and scientists. It is also one segment of a wider social, political, economic, and environmental totality.

At a local level Durrenberger investigates the impact of competition from Vietnamese refugees, rivalry between bay and gulf fishermen, an escalating overpopulation of shrimpers in general, and wide-spread resistance to costly, federally mandated devices designed to save sea turtles. Exploring how the industry is increasingly bound to the global economy, he illuminates the threat to the livelihoods of independent shrimpers from ever increasing imports.

Durrenberger assesses the adequacy of folk models of shrimpers and policymakers alike. Decisions about the industry's future, he argues, must be based on valid data and realistic expectations. Too often policies are derived from untested folk models--concepts formulated by participants to justify or rationalize rather than explain what they do.

This volume is a compilation of Dinophyceae which are of interest to phycologists and protozoologists. Since it is very difficult to classify of the unicellular organisms as plants or animals two approaches can be found to the classification of dinoflagellates - the botanical and zoological. We have employed the phycological (botanical) approach in our textbook. However, we view the dinoflagellates as protists which exhibit both plant and animal features.

Classically phycologists divided dinoflagellates into monads, rhizopods, coccals, capsals and trichals based on morphology. During our studies of freshwater dinoflagellates we have observed and recorded stages transcendent among these forms. We have also lumped many poorly described species. We have listed in the appendix all the freshwater species known. Thus we face a dilemma wether to compile dinoflagellates according to classical systematics or to use the classical approach inserting new information. We have chosen the latter.

Modern North American sturgeons and paddlefish are the result of 100 million years of evolution. Once an integral part of aboriginal culture, their numbers were decimated by overfishing and habitat destruction during the past two centuries.

This book details the extensive science aimed at helping these remarkable species recover from the brink of extinction, and describes the historical, biological, and ecological importance of North American sturgeon and paddlefish. The text is enhanced by photographs and detailed line drawings.

This comprehensive volume will be an invaluable resource for researchers, educators, and consultants, in academic and government settings, who work to further scientific understanding of these fishes. No other single compilation has documented current information in such detail.
