Introduction to the General Principles of Aquaculture provides novice aquaculturists with an overview of the aquaculture industry so you may proceed successfully in academic studies or commercial ventures. The authors furnish you with insight into the history and development of aquaculture and cover the subjects of natural production versus aquaculture, the aquatic environment, energy requirements of and relationships in aquaculture systems, important components of aquaculture systems, selection of aquaculture species, major cultured species and their distribution, global aquaculture production, a comparison of agriculture and aquaculture, and those factors promoting and constraining aquaculture. The book is liberally illustrated so that students and laymen are able to visualize systems and species. Furthermore, tables and figures are used throughout to emphasize important points, facts, and methods. As an introductory text, it emphasizes several aspects of aquaculture that must be understood by those new to the industry. These aspects include water quality, species of importance around the world, and current and projected aquaculture production on a global basis. The important components of any aquaculture system are also covered in some detail--biological factors, technical-biological factors, technical-economic factors, production cost factors, socioeconomic factors, and species selection factors.Laypersons considering aquaculture as an investment and students considering aquaculture as a career, but who have no real background in agriculture and fisheries sciences,will find this book to be a key information source. Introduction to the General Principles of Aquaculture is written with the global market in mind and instructors will find it to be a useful introductory text at the undergraduate level.

Freshwater Crayfish Aquaculture in North America, Europe, and Australia is the first text to summarize the methods of culture for the eight most important crayfish species in the world. Methods developed to culture crayfishes around the world differ significantly, and this book enables readers to develop workable strategies for cultivating different crayfish species in specific environments. Huner and associate authors cover the following topics in detail:methods of crayfish culturecrayfish diseasescrayfish processingeconomics of crayfish cultureEach of the the three major crayfish industries are well-represented in this new book and special attention is given to the specific needs and accomplishments of each area, which is beneficial to producers in other countries. For example, while hatching technology has been important in Australia and Europe, it hasn?t yet been applied to any degree in North America. At the same time, North America has developed a major crayfish processing industry. Disease problems have resulted in more emphasis on that subject in Europe and yet it is vital to all involved in crayfish aquaculture. Businessmen, farmers, scientists, laymen, or students need to be exposed to the methods and problems associated with crayfish production in different parts of the world if they are to be successful in any crayfish project, whether it be research- or profit-oriented. Freshwater Crayfish Aquaculture in North America, Europe, and Australia is intended to provide all readers with one source of information on the subject of freshwater crayfish aquaculture.Professional staff, advanced students, and extension personnel will find the entire text beneficial. Those in corporate organizations and the agriculture field, especially decisionmakersin operations, will find the methods, markets, and financial considerations in this book a helpful guide.
