Book Description
The interactions between wild bird populations (many protected by law) and fish, particularly those under commercial culture or part of a fishery is subject of much controversy. Ecological, environmental and conservation pressures run alongside commercial pressures on exploited fish populations. This exciting book draws together contributions from all over the world to provide a fascinating insight into many case studies and conflicts in managed situations as well as looking at the overall ecology of such interactions in normal un-managed ecosystems.

Book Description
Behold the cormorant: silent, still, cruciform, and brooding; flashing, soaring, quick as a snake. Evolution has crafted the only creature on Earth that can migrate the length of a continent, dive and hunt deep underwater, perch comfortably on a branch or a wire, walk on land, climb up cliff faces, feed on thousands of different species, and live beside both fresh and salt water in a vast global range of temperatures and altitudes, often in close proximity to man. Long a symbol of gluttony, greed, bad luck, and evil, the cormorant has led a troubled existence in human history, myth, and literature. The birds have been prized as a source of mineral wealth in Peru, hunted to extinction in the Arctic, trained by the Japanese to catch fish, demonized by Milton in Paradise Lost, and reviled, despised, and exterminated by sport and commercial fishermen from Israel to Indianapolis, Toronto to Tierra del Fuego. In The DevilÕs Cormorant, Richard King takes us back in time and around the world to show us the history, nature, ecology, and economy of the worldÕs most misunderstood waterfowl.

Book Description
The double-crested cormorant, found only in North America, is an iridescent black waterbird superbly adapted to catch fish. It belongs to a family of birds vilified since biblical times and persecuted around the world. Thus it was perhaps to be expected that the first European settlers in North America quickly deemed the double-crested cormorant a competitor for fishing stock and undertook a relentless drive to destroy the birds. This enormously important book explores the roots of human-cormorant conflicts, dispels myths about the birds, and offers the first comprehensive assessment of the policies that have been developed to manage the double-crested cormorant in the twenty-first century. Conservation biologist Linda Wires provides a unique synthesis of the cultural, historical, scientific, and political elements of the cormorant’s story. She discusses the amazing late-twentieth-century population recovery, aided by protection policies and environment conservation, but also the subsequent U.S. federal policies under which hundreds of thousands of the birds have been killed. In a critique of the science, management, and ethics underlying the double-crested cormorant’s treatment today, Wires exposes “management” as a euphemism for persecution and shows that the current strategies of aggressive predator control are outdated and unsupported by science.

Book Description
This is the story of the survival, recovery, astonishing success, and controversial status of the double-crested cormorant. After surviving near extinction driven by DDT and other contaminants from the 1940s through the early 1970s, the cormorant has made an unprecedented comeback from mere dozens to a population in the millions, bringing the bird again into direct conflict with humans. Hated for its colonial nesting behavior; the changes it brings to landscapes; and especially its competition with commercial and sports fishers, fisheries, and fish farmers throughout the Great Lakes and Mississippi Delta regions, the cormorant continues to be persecuted by various means, including the shotgun. In The Double-Crested Cormorant, Dennis Wild brings together the biological, social, legal, and international aspects of the cormorant's world to give a complete and balanced view of one of the Great Lakes' and perhaps North America's most misunderstood species. In addition to taking a detailed look at the complex natural history of the cormorant, the book explores the implications of congressional acts and international treaties, the workings and philosophies of state and federal wildlife agencies, the unrelenting efforts of aquaculture and fishing interests to "cull" cormorant numbers to "acceptable" levels, and the reactions and visions of conservation groups. Wild examines both popular preconceptions about cormorants (what kinds of fish they eat and how much) and the effectiveness of ongoing efforts to control the cormorant population. Finally, the book delves into the question of climate and terrain changes, their consequences for cormorants, the new territories to which the birds must adapt, and the conflicts this species is likely to face going forward.

Book Description
The history of channel catfish farming in the United States serves as a model for the development of pond-based aquaculture industries worldwide. Channel catfish farming is the largest and economically most important aquaculture industry in the United States. In 2003, over 300,000 metric tons (662 million pounds) of channel catfish were processed, representing about half the total United States aquaculture production. Demand for farm-raised catfish is strong, with record processing years in 2002 and 2003. In 22 chapters written by active scientists in the field, Biology and Culture of Channel Catfish comprehensively synthesizes over 30 years of research on this American icon. Throughout the book, fundamental biological aspects of channel catfish are linked to practical culture techniques. Topics include: • Latest information on reproductive physiology, genetics, and breeding • Comprehensive treatment of catfish nutrition, feeds, and feeding practices • Water quality management and pond dynamics • In-depth review of immunology in channel catfish • Practical information on diseases and health management • Techniques for commercial culture, including innovative techniques such as raceways, recirculating systems, and partitioned aquaculture systems • Catfish economics and marketing • Exploration of environmental concerns, including recommended Best Management Practices
