Examine the world's leading aquaculture producers! Sustainable Aquaculture: Global Perspectives is a one-of-a-kind primer on the world's leading sources of aquatic production, presenting expert commentary that includes the latest advancements, developments, and research findings. The book examines essential elements of aquaculture (water quality, nutrition, genetics, culture methods) and addresses problems such as over-fishing, coastal and wetland destruction, and habitat and environmental degradation. Sustainable Aquaculture: Global Perspectives addresses policy measures that are essential for the long-term sustainability of the world's fisheries—and the long-term employment of those who rely on the aquaculture industry for their livelihood. As the world's population increases at an alarming rate, the question of how to ensure global food security is one of extreme importance. But the world's total yield is below expectations and the book examines the reasons why: the under-utilization of natural resources, the lack of adoption of modern scientific methods, the lack of standardized, proven pond fertilization protocols; long-term inbreeding and the loss of genetic variability due to genetic drift. Sustainable Aquaculture: Global Perspectives also addresses: freshwater pearl culture breeding programs pond fertilization regimes fish diseases in tropical climates indoor recirculating culture systems water quality management for shrimp farming and much more! With much of its information available in one place for the first time, Sustainable Aquaculture: Global Perspectives is invaluable as a textbook for introductory aquaculture courses and is an essential resource for professionals and researchers.
Safeguard the success of aquaculture operations without expensive antibiotics!Diseases are a major threat to the sustainability of the aquaculture industry.

Everybody Out of the Pond At the Water's Edge will change the way you think about your place in the world. The awesome journey of life's transformation from the first microbes 4 billion years ago to Homo sapiens today is an epic that we are only now beginning to grasp. Magnificent and bizarre, it is the story of how we got here, what we left behind, and what we brought with us. We all know about evolution, but it still seems absurd that our ancestors were fish. Darwin's idea of natural selection was the key to solving generation-to-generation evolution -- microevolution -- but it could only point us toward a complete explanation, still to come, of the engines of macroevolution, the transformation of body shapes across millions of years. Now, drawing on the latest fossil discoveries and breakthrough scientific analysis, Carl Zimmer reveals how macroevolution works. Escorting us along the trail of discovery up to the current dramatic research in paleontology, ecology, genetics, and embryology, Zimmer shows how scientists today are unveiling the secrets of life that biologists struggled with two centuries ago. In this book, you will find a dazzling, brash literary talent and a rigorous scientific sensibility gracefully brought together. Carl Zimmer provides a comprehensive, lucid, and authoritative answer to the mystery of how nature actually made itself.

Originally formed to harbor freed slaves and Americans returning to Africa, Liberia once was a land of hope. That was shattered by a long Civil War that shook its very foundation. Today's Liberia is glimpsed in this second edition. Building on the first edition, this updated volume focuses on the personalities, from the founders of Liberia, to the soldiers who are responsible simultaneously for destruction and the hope of stability. Along with these people, various social and ethnic groups, political parties and labor movements, economic entities and natural resources are profiled in this updated work. A new chronology of Liberia is included, and a selected bibliography suggests further readings for the scholar.
Richard explores the enshrinement of the classics in American antebellum culture. For the first time, knowledge of the classics extended beyond aristocratic males to the middle class, women, African Americans, and frontier settlers, but the Civil War led to a radical alteration of the educational system that steadily eroded their preeminence.
This monumental collection of correspondence between Gertrude Stein and critic, novelist, and photographer Carl Van Vechten provides crucial insight into Stein's life, art, and artistic milieu as well as Van Vechten's support of major cultural projects, such as the Harlem Renaissance. From their first meeting in 1913, Stein and Van Vechten formed a unique and powerful relationship, and Van Vechten worked vigorously to publish and promote Stein's work. Existing biographies of Stein--including her own autobiographical writings--omit a great deal about her experiences and thought. They lack the ordinary detail of what Stein called "daily everyday living" the immediate concerns, objects, people, and places that were the grist for her writing. These letters not only vividly represent those details but also showcase Stein and Van Vechten's private selves as writers. Edward Burns's extensive annotations include detailed cross-referencing of source materials.
This volume presents nearly 250 of Lincoln's most important speeches, state papers, and letters in their entirety. Here are not only the masterpieces—the Gettysburg Address, the Inaugural Addresses, the 1858 Republican Convention Speech, the Emancipation Proclamation—but hundreds of lesser-known gems. Alfred Kazin has written that Lincoln was "not just the greatest writer among our Presidents . . . but the most telling and unforgettable of all American 'public' writer-speakers," and it's never been cleaner than in this comprehensive edition.
This definitive, single-volume edition of the Pulitzer Prize–winning biography delivers “a Lincoln whom no other man . . . could have given us” (New York Herald Tribune Book Review). Celebrated for his vivid depictions of the nineteenth-century American Midwest, Carl Sandburg brings unique insight to the life of Abraham Lincoln in this distinguished biography. He captures both the man who grew up on the Indiana prairie and the president who held the country together through the turbulence and tragedy of the Civil War. Based on a lifetime of research, Sandburg’s biographywas originally published as a monumental, six-volume study. The author later distilled the work down to this single-volume edition that is considered by many to be his greatest work of nonfiction.
A champion of spread-eagle expansionism and an ardent nationalist, Cass subscribed to the Jeffersonian political philosophy, embracing the principles of individual liberty; the sovereignty of the people; equality of rights and opportunities for all citizens; and a strictly construed and balanced constitutional government of limited powers.
Drawing on a deep understanding of the shades and structures of the blues, Steven C. Tracy elucidates the vital relationship between this musical form and the art of Langston Hughes, preeminent poet of the Harlem Renaissance. Tracy provides a cultural context for the poet's work and shows how Hughes mined African-American oral and literary traditions to create his blues-inspired poetry. Through a detailed comparison of Hughes's poems to blues texts, Tracy demonstrates how the poetics, structures, rhythms, and musical techniques of the blues are reflected in Hughes's experimental forms. The volume also includes a discography of recordings by the blues artists--Bessie Smith, Ma Rainey, Blind Lemon Jefferson, and others-who most influenced Hughes, updated in a new introduction by the author.
The year 1816 found America on the cusp of political, social, cultural, and economic modernity. Celebrating its fortieth year of independence, the country's sense of self was maturing. Americans, who had emerged from the War of 1812 with their political system intact, embraced new opportunities. For the first time, citizens viewed themselves not as members of a loose coalition of states but as part of a larger union. This optimism was colored, however, by bizarre weather. Periods of extreme cold and severe drought swept the northern states and the upper south throughout 1816, often referred to as The Year Without a Summer. Faced with thirty-degree summer temperatures, many farmers migrated west in search of better weather and more fertile farmlands. In 1816, historian C. Edward Skeen illuminates this unique year of national transition. Politically, the era of good feelings allowed Congress to devise programs that fostered prosperity. Social reform movements flourished. This election year found the Federalist party in its death throes, seeking cooperation with the nationalistic forces of the Republican party. Movement west, maturation of political parties, and increasingly conte
