As traditional commercial fishing becomes increasingly expensive and restrictive, aquacultural fish production emerges as a practical viable alternative. The Aquaculture Sourcebook is an introductory text and ready reference for information on the fresh-, brackish-, and salt-water farming of both fish and shellfish, as well as of several important algae. Until now, such material has been available only in scattered publications; but the Aquaculture Sourcebook incorporates all the feasibility data pertinent to farming aquacultural species in North America into one easy-to-use text. It will be welcomed not only by current and future aquaculturists, but also by fisheries, seafood company managers, biologists, teachers, and students. The Aquaculture Sourcebook has been designed to satisfy the needs of fisheries, scientists, and commercial aquaculturists by providing, in a handy and well-organized format, information vital for successful North American aquacultural ventures. Concise details are given for over a hundred individual speices, including not only those raised for human consumption, but also organisms reared for feed, bait, or other purposes. Each entry in this valuable volume covers such relevant material as: *the scientific and common names of the organism *its visual appearance and distinctive characteristics *habitat range specifications *species reproduction and development *age- and growth-related factors *specific parasites an diseases *potential predators and/or competitive species *its prospects for future aquacultural success Key groups of closely related species are discussed in a geographical context, highlighting areas which each will find the habitat best for its survival. Great care has been taken to specify ranges of tolerable salinity and optimum temperature for candidate species, and emphasis has been placed on creating aquacultural environments that replicate those normally habitated in nature. Comprehensive, informative, and accessible to layperson and scientist alike, the Aqualculture Sourcebook is both the perfect desktop reference for anyone establishing an aquacultural facility, and a ready reference to help maintain one.

Originally published in 1993, The Medieval World of Nature looks at how the natural world was viewed by medieval society. The book presents the argument that the pragmatic medieval view of the natural world of animals and plants, existed simply to serve medieval society. It discusses the medieval concept of animals as food, labour, and sport and addresses how the biblical charge of assuming dominion over animals and plants, was rooted in the medieval sensibility of control. The book also looks at the idea of plants and animals as not only pragmatic, but as allegories within the medieval world, utilizing animals to draw morality tales, which were viewed with as much importance as scientific information. This book provides a unique and interesting look at the everyday medieval world.

With more than 29,000 species, fishes are the most diverse group of vertebrates on the planet. Of that number, more than 12,000 species are found in freshwater ecosystems, which occupy less than 1 percent of the Earth’s surface and contain only 2.4 percent of plant and animal species. But, on a hectare-for-hectare basis, freshwater ecosystems are richer in species than more extensive terrestrial and marine habitats. Examination of the distribution patterns of fishes in these fresh waters reveals much about continental movements and climate changes and has long been critical to biogeographical studies and research in ecology and evolution. Tim Berra’s seminal resource, Freshwater Fish Distribution,maps the 169 fish families that swim in fresh water around the world. Each family account includes the class, subclass, and order; a pronunciation guide to the family name; life cycle information; and interesting natural history facts. Each account is illustrated, many with historical nineteenth-century woodcuts. Now available in paperback, this heavily cited work in ichthyology and biogeography will serve as a reference for students, a research support for professors, and a helpful guide to tropical fish hobbyists and anglers.
